+# App Settings & Theme System
+
+## Overview
+
+The app uses a centralized `AppSettingsBox` (Hive) for storing all app-level settings. This includes theme preferences, language settings, notification preferences, and other user configurations.
+
+---
+
+## AppSettingsBox
+
+**Location**: `lib/core/database/app_settings_box.dart`
+
+### Initialization
+
+```dart
+// In main.dart - call before runApp()
+await AppSettingsBox.init();
+```
+
+### Storage Keys
+
+| Key | Type | Default | Description |
+|-----|------|---------|-------------|
+| **Theme** |
+| `seed_color_id` | String | `'blue'` | Selected theme color ID |
+| `theme_mode` | int | `0` | 0=system, 1=light, 2=dark |
+| **Language** |
+| `language_code` | String | `'vi'` | Language code (vi, en) |
+| **Notifications** |
+| `notifications_enabled` | bool | `true` | Master notification toggle |
+| `order_notifications` | bool | `true` | Order status notifications |
+| `promotion_notifications` | bool | `true` | Promotion notifications |
+| `chat_notifications` | bool | `true` | Chat message notifications |
+| **User Preferences** |
+| `onboarding_completed` | bool | `false` | Onboarding flow completed |
+| `biometric_enabled` | bool | `false` | Biometric login enabled |
+| `remember_login` | bool | `false` | Remember login credentials |
+| **App State** |
+| `last_sync_time` | String | - | Last data sync timestamp |
+| `app_version` | String | - | Last launched app version |
+| `first_launch_date` | String | - | First app launch date |
+
+### Usage
+
+```dart
+// Generic get/set
+AppSettingsBox.get<String>('key', defaultValue: 'default');
+await AppSettingsBox.set('key', value);
+
+// Helper methods
+AppSettingsBox.getSeedColorId();           // Returns 'blue', 'teal', etc.
+await AppSettingsBox.setSeedColorId('teal');
+
+AppSettingsBox.getThemeModeIndex();        // Returns 0, 1, or 2
+await AppSettingsBox.setThemeModeIndex(1);
+
+AppSettingsBox.getLanguageCode();          // Returns 'vi' or 'en'
+await AppSettingsBox.setLanguageCode('en');
+
+AppSettingsBox.areNotificationsEnabled();  // Returns true/false
+AppSettingsBox.isOnboardingCompleted();
+AppSettingsBox.isBiometricEnabled();
+```
+
+---
+
+## Theme System
+
+### Architecture
+
+```
+colors.dart          → Seed color options & status colors
+app_theme.dart       → ThemeData generation from seed color
+theme_provider.dart  → Riverpod state management
+```
+
+### Available Seed Colors
+
+| ID | Name | Color |
+|----|------|-------|
+| `blue` | Xanh dương | `#005B9A` (default) |
+| `teal` | Xanh ngọc | `#009688` |
+| `green` | Xanh lá | `#4CAF50` |
+| `purple` | Tím | `#673AB7` |
+| `indigo` | Chàm | `#3F51B5` |
+| `orange` | Cam | `#FF5722` |
+| `red` | Đỏ | `#E53935` |
+| `pink` | Hồng | `#E91E63` |
+
+### Providers
+
+```dart
+// Main theme settings provider (persisted)
+themeSettingsProvider
+
+// Convenience providers
+currentSeedColorProvider     // Color - current seed color
+seedColorOptionsProvider     // List<SeedColorOption> - all options
+```
+
+### Usage in App
+
+```dart
+// app.dart - Dynamic theme
+class MyApp extends ConsumerWidget {
+  @override
+  Widget build(BuildContext context, WidgetRef ref) {
+    final settings = ref.watch(themeSettingsProvider);
+
+    return MaterialApp(
+      theme: AppTheme.lightTheme(settings.seedColor),
+      darkTheme: AppTheme.darkTheme(settings.seedColor),
+      themeMode: settings.themeMode,
+      // ...
+    );
+  }
+}
+```
+
+### Changing Theme
+
+```dart
+// Change seed color
+ref.read(themeSettingsProvider.notifier).setSeedColor('teal');
+
+// Change theme mode
+ref.read(themeSettingsProvider.notifier).setThemeMode(ThemeMode.dark);
+
+// Toggle light/dark
+ref.read(themeSettingsProvider.notifier).toggleThemeMode();
+```
+
+### Color Picker Widget Example
+
+```dart
+class ColorPickerWidget extends ConsumerWidget {
+  @override
+  Widget build(BuildContext context, WidgetRef ref) {
+    final options = ref.watch(seedColorOptionsProvider);
+    final current = ref.watch(themeSettingsProvider);
+
+    return Wrap(
+      spacing: 8,
+      children: options.map((option) {
+        final isSelected = option.id == current.seedColorId;
+        return GestureDetector(
+          onTap: () => ref
+              .read(themeSettingsProvider.notifier)
+              .setSeedColor(option.id),
+          child: Container(
+            width: 48,
+            height: 48,
+            decoration: BoxDecoration(
+              color: option.color,
+              shape: BoxShape.circle,
+              border: isSelected
+                  ? Border.all(color: Colors.white, width: 3)
+                  : null,
+            ),
+            child: isSelected
+                ? const Icon(Icons.check, color: Colors.white)
+                : null,
+          ),
+        );
+      }).toList(),
+    );
+  }
+}
+```
+
+---
+
+## Using ColorScheme
+
+With the `fromSeed()` approach, always use `Theme.of(context).colorScheme` for colors:
+
+```dart
+// Via context extension (recommended)
+final cs = context.colorScheme;
+
+// Common color usage
+cs.primary              // Main brand color (buttons, links)
+cs.onPrimary            // Text/icons on primary color
+cs.primaryContainer     // Softer brand background
+cs.onPrimaryContainer   // Text on primaryContainer
+
+cs.secondary            // Secondary accent
+cs.tertiary             // Third accent color
+
+cs.surface              // Card/container backgrounds
+cs.onSurface            // Primary text color
+cs.onSurfaceVariant     // Secondary text color
+
+cs.outline              // Borders, dividers
+cs.outlineVariant       // Lighter borders
+
+cs.error                // Error states
+cs.onError              // Text on error
+
+// Example widget
+Container(
+  color: cs.primaryContainer,
+  child: Text(
+    'Hello',
+    style: TextStyle(color: cs.onPrimaryContainer),
+  ),
+)
+```
+
+### Status Colors (Fixed)
+
+These colors don't change with theme (from backend):
+
+```dart
+AppColors.success   // #28a745 - Green
+AppColors.warning   // #ffc107 - Yellow
+AppColors.danger    // #dc3545 - Red
+AppColors.info      // #17a2b8 - Blue
+```
+

+3. ✅ `lib/features/account/data/models/city_model.dart`
+4. ✅ `lib/features/account/data/models/ward_model.dart`
+5. ✅ Updated `lib/core/constants/storage_constants.dart`
+   - Added `cityBox` and `wardBox`
+   - Added `cityModel = 31` and `wardModel = 32`
+   - Shifted all enum IDs by +2
+
+## Implementation Status
+
+### Completed:
+- ✅ Domain entities (City, Ward)
+- ✅ Hive models with type adapters
+- ✅ Storage constants updated
+- ✅ Build runner generated .g.dart files
+
+### Remaining (Need to implement):
+
+1. **Remote Datasource** - `lib/features/account/data/datasources/location_remote_datasource.dart`
+2. **Local Datasource** - `lib/features/account/data/datasources/location_local_datasource.dart`
+3. **Repository Interface** - `lib/features/account/domain/repositories/location_repository.dart`
+4. **Repository Implementation** - `lib/features/account/data/repositories/location_repository_impl.dart`
+5. **Providers** - `lib/features/account/presentation/providers/location_provider.dart`
+6. **Update AddressFormPage** to use the providers
+
+## API Endpoints (from docs/auth.sh)
+
+### Get Cities:
+```bash
+POST /api/method/frappe.client.get_list
+Body: {
+  "doctype": "City",
+  "fields": ["city_name","name","code"],
+  "limit_page_length": 0
+}
+```
+
+### Get Wards (filtered by city):
+```bash
+POST /api/method/frappe.client.get_list
+Body: {
+  "doctype": "Ward",
+  "fields": ["ward_name","name","code"],
+  "filters": {"city": "96"},
+  "limit_page_length": 0
+}
+```
+
+## Offline-First Strategy
+
+1. **Cities**: Cache in Hive, refresh from API periodically
+2. **Wards**: Load from API when city selected, cache per city
+
+Would you like me to generate the remaining implementation files now?

+# Favorites Feature Simplification Summary
+# Date: 2025-11-18
+# 
+# CHANGES MADE:
+# =============
+#
+# 1. Simplified favorites_provider.dart
+#    - Removed old Favorites provider (Set<String> of product IDs)
+#    - Kept only FavoriteProducts provider (List<Product>)
+#    - Helper providers now derive from FavoriteProducts:
+#      * isFavorite(productId) - checks if product is in list
+#      * favoriteCount() - counts products in list
+#      * favoriteProductIds() - maps to list of product IDs
+#    - Add/remove methods now use favoriteProductsProvider.notifier
+#    - No userId filtering - uses authenticated API session
+#
+# 2. Updated favorites_page.dart
+#    - Changed clearAll to show "under development" message
+#    - Still watches favoriteProductsProvider (already correct)
+#
+# 3. Updated favorite_product_card.dart
+#    - Changed from favoritesProvider.notifier to favoriteProductsProvider.notifier
+#    - Remove favorite now calls the correct provider
+#
+# 4. Updated product_detail_page.dart
+#    - Changed toggleFavorite from favoritesProvider.notifier to favoriteProductsProvider.notifier
+#
+# KEY BEHAVIORS:
+# ==============
+#
+# - All favorites operations work with Product entities directly
+# - No userId parameter needed in UI code
+# - Repository methods still use 'current_user' as dummy userId for backwards compatibility
+# - API calls use authenticated session (token-based)
+# - Add/remove operations refresh the products list after success
+# - Helper providers safely return defaults during loading/error states
+#
+# FILES MODIFIED:
+# ==============
+# 1. lib/features/favorites/presentation/providers/favorites_provider.dart
+# 2. lib/features/favorites/presentation/pages/favorites_page.dart
+# 3. lib/features/favorites/presentation/widgets/favorite_product_card.dart
+# 4. lib/features/products/presentation/pages/product_detail_page.dart
+#
+# ARCHITECTURE:
+# ============
+#
+# Main Provider:
+#   FavoriteProducts (AsyncNotifierProvider<List<Product>>)
+#     ├── build() - loads products from repository
+#     ├── addFavorite(productId) - calls API, refreshes list
+#     ├── removeFavorite(productId) - calls API, refreshes list
+#     ├── toggleFavorite(productId) - adds or removes based on current state
+#     └── refresh() - manual refresh for pull-to-refresh
+#
+# Helper Providers (derived from FavoriteProducts):
+#   isFavorite(productId) - bool
+#   favoriteCount() - int
+#   favoriteProductIds() - List<String>
+#
+# Data Flow:
+#   UI -> FavoriteProducts.notifier.method() -> Repository -> API
+#   API Response -> Repository caches locally -> Provider updates state
+#   Helper Providers watch FavoriteProducts and derive values
+#
+# TESTING:
+# ========
+# To verify the changes work:
+# 1. Add products to favorites from product detail page
+# 2. View favorites page - should load product list
+# 3. Remove products from favorites page
+# 4. Toggle favorites from product cards
+# 5. Check that favoriteCount updates in real-time
+# 6. Test offline mode - should use cached products
+
+echo "Favorites feature simplified successfully!"
+echo "Main provider: FavoriteProducts (List<Product>)"
+echo "Helper providers derive from product list"
+echo "No userId filtering - uses API auth session"

+**# Authentication Flow - Frappe/ERPNext Integration
+
+## Overview
+
+The authentication system integrates with Frappe/ERPNext API using a session-based approach with SID (Session ID) and CSRF tokens stored in FlutterSecureStorage.
+
+## Complete Flow
+
+### 1. App Startup (Check Saved Session)
+
+**When**: User opens the app
+
+**Process**:
+1. `Auth` provider's `build()` method is called
+2. Checks if user session exists in FlutterSecureStorage
+3. If logged-in session exists (userId != public_api@dbiz.com), returns User entity
+4. Otherwise returns `null` (user not logged in)
+5. **Note**: Public session is NOT fetched on startup to avoid provider disposal issues
+
+**Important**: The public session will be fetched lazily when needed:
+- Before login (on login page load)
+- Before registration (when loading cities/customer groups)
+- Before any API call that requires session (via `ensureSession()`)
+
+**API Endpoint**: `POST /api/method/dbiz_common.dbiz_common.api.auth.get_session`
+
+**Request**:
+```bash
+curl -X POST 'https://land.dbiz.com/api/method/dbiz_common.dbiz_common.api.auth.get_session' \
+  -H 'Content-Type: application/json' \
+  -d ''
+```
+
+**Response**:
+```json
+{
+  "session_expired": 1,
+  "message": {
+    "data": {
+      "sid": "8c39b583...",
+      "csrf_token": "f8a7754a9ce5..."
+    }
+  },
+  "home_page": "/app",
+  "full_name": "Guest"
+}
+```
+
+**Storage** (FlutterSecureStorage):
+- `frappe_sid`: "8c39b583..."
+- `frappe_csrf_token`: "f8a7754a9ce5..."
+- `frappe_full_name`: "Guest"
+- `frappe_user_id`: "public_api@dbiz.com"
+
+---
+
+### 2. Initialize Public Session (When Needed)
+
+**When**: Before login or registration, or before any API call
+
+**Process**:
+1. Call `ref.read(initializeFrappeSessionProvider.future)` on the page
+2. Checks if session exists in FlutterSecureStorage
+3. If no session, calls `FrappeAuthService.getSession()`
+4. Stores public session (sid, csrf_token) in FlutterSecureStorage
+
+**Usage Example**:
+```dart
+// In login page or registration page initState/useEffect
+@override
+void initState() {
+  super.initState();
+  // Initialize session when page loads
+  WidgetsBinding.instance.addPostFrameCallback((_) {
+    ref.read(initializeFrappeSessionProvider.future);
+  });
+}
+```
+
+Or use `FutureBuilder`:
+```dart
+FutureBuilder(
+  future: ref.read(initializeFrappeSessionProvider.future),
+  builder: (context, snapshot) {
+    if (snapshot.connectionState == ConnectionState.waiting) {
+      return LoadingIndicator();
+    }
+    return LoginForm(); // or RegistrationForm
+  },
+)
+```
+
+### 3. Loading Cities & Customer Groups (Using Public Session)
+
+**When**: User navigates to registration screen
+
+**Process**:
+1. Session initialized (if not already) via `initializeFrappeSessionProvider`
+2. `AuthRemoteDataSource.getCities()` is called
+3. Gets stored session from FlutterSecureStorage
+4. Calls API with session headers
+5. Returns list of cities for address selection
+
+**API Endpoint**: `POST /api/method/frappe.client.get_list`
+
+**Request**:
+```bash
+curl -X POST 'https://land.dbiz.com/api/method/frappe.client.get_list' \
+  -H 'Cookie: sid=8c39b583...; full_name=Guest; system_user=no; user_id=public_api%40dbiz.com; user_image=' \
+  -H 'X-Frappe-CSRF-Token: f8a7754a9ce5...' \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "doctype": "City",
+    "fields": ["city_name", "name", "code"],
+    "limit_page_length": 0
+  }'
+```
+
+**Response**:
+```json
+{
+  "message": [
+    {"city_name": "Hồ Chí Minh", "name": "HCM", "code": "HCM"},
+    {"city_name": "Hà Nội", "name": "HN", "code": "HN"}
+  ]
+}
+```
+
+**Similarly for Customer Groups**:
+```json
+{
+  "doctype": "Customer Group",
+  "fields": ["customer_group_name", "name", "value"],
+  "filters": {
+    "is_group": 0,
+    "is_active": 1,
+    "customer": 1
+  }
+}
+```
+
+---
+
+### 4. User Login (Get Authenticated Session)
+
+**When**: User enters phone number and password, clicks login
+
+**Process**:
+1. `Auth.login()` is called with phone number
+2. Gets current session from FlutterSecureStorage
+3. Calls `AuthRemoteDataSource.login()` with phone + current session
+4. API returns new authenticated session
+5. `FrappeAuthService.login()` stores new session in FlutterSecureStorage
+6. Dio interceptor automatically uses new session for all subsequent requests
+7. Returns `User` entity with user data
+
+**API Endpoint**: `POST /api/method/building_material.building_material.api.auth.login`
+
+**Request**:
+```bash
+curl -X POST 'https://land.dbiz.com/api/method/building_material.building_material.api.auth.login' \
+  -H 'Cookie: sid=8c39b583...' \
+  -H 'X-Frappe-CSRF-Token: f8a7754a9ce5...' \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "username": "0123456789",
+    "googleid": null,
+    "facebookid": null,
+    "zaloid": null
+  }'
+```
+
+**Response**:
+```json
+{
+  "session_expired": 1,
+  "message": {
+    "data": {
+      "sid": "new_authenticated_sid_123...",
+      "csrf_token": "new_csrf_token_456..."
+    }
+  },
+  "home_page": "/app",
+  "full_name": "Nguyễn Văn A"
+}
+```
+
+**Storage Update** (FlutterSecureStorage):
+- `frappe_sid`: "new_authenticated_sid_123..."
+- `frappe_csrf_token`: "new_csrf_token_456..."
+- `frappe_full_name`: "Nguyễn Văn A"
+- `frappe_user_id`: "0123456789"
+
+---
+
+### 5. Authenticated API Requests
+
+**When**: User makes any API request after login
+
+**Process**:
+1. `AuthInterceptor.onRequest()` is called
+2. Reads session from FlutterSecureStorage
+3. Builds cookie header with all required fields
+4. Adds headers to request
+
+**Cookie Header Format**:
+```
+Cookie: sid=new_authenticated_sid_123...; full_name=Nguyễn Văn A; system_user=no; user_id=0123456789; user_image=
+X-Frappe-CSRF-Token: new_csrf_token_456...
+```
+
+**Example**: Getting products
+```bash
+curl -X POST 'https://land.dbiz.com/api/method/frappe.client.get_list' \
+  -H 'Cookie: sid=new_authenticated_sid_123...; full_name=Nguyễn%20Văn%20A; system_user=no; user_id=0123456789; user_image=' \
+  -H 'X-Frappe-CSRF-Token: new_csrf_token_456...' \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "doctype": "Item",
+    "fields": ["item_name", "item_code", "standard_rate"],
+    "limit_page_length": 20
+  }'
+```
+
+---
+
+### 6. User Logout
+
+**When**: User clicks logout button
+
+**Process**:
+1. `Auth.logout()` is called
+2. Clears session from both:
+   - `AuthLocalDataSource` (legacy Hive)
+   - `FrappeAuthService` (FlutterSecureStorage)
+3. Gets new public session for next login/registration
+4. Returns `null` (user logged out)
+
+**Storage Cleared**:
+- `frappe_sid`
+- `frappe_csrf_token`
+- `frappe_full_name`
+- `frappe_user_id`
+
+**New Public Session**: Immediately calls `getSession()` again to get fresh public session
+
+---
+
+## File Structure
+
+### Core Services
+- `lib/core/services/frappe_auth_service.dart` - Centralized session management
+- `lib/core/models/frappe_session_model.dart` - Session response model
+- `lib/core/network/api_interceptor.dart` - Dio interceptor for adding session headers
+
+### Auth Feature
+- `lib/features/auth/data/datasources/auth_remote_datasource.dart` - API calls (login, getCities, getCustomerGroups, register)
+- `lib/features/auth/data/datasources/auth_local_datasource.dart` - Legacy Hive storage
+- `lib/features/auth/presentation/providers/auth_provider.dart` - State management
+
+### Key Components
+
+**FrappeAuthService**:
+```dart
+class FrappeAuthService {
+  Future<FrappeSessionResponse> getSession(); // Get public session
+  Future<FrappeSessionResponse> login(String phone, {String? password}); // Login
+  Future<Map<String, String>?> getStoredSession(); // Read from storage
+  Future<Map<String, String>> ensureSession(); // Ensure session exists
+  Future<Map<String, String>> getHeaders(); // Get headers for API calls
+  Future<void> clearSession(); // Clear on logout
+}
+```
+
+**AuthRemoteDataSource**:
+```dart
+class AuthRemoteDataSource {
+  Future<GetSessionResponse> getSession(); // Wrapper for Frappe getSession
+  Future<GetSessionResponse> login({phone, csrfToken, sid, password}); // Login API
+  Future<List<City>> getCities({csrfToken, sid}); // Get cities for registration
+  Future<List<CustomerGroup>> getCustomerGroups({csrfToken, sid}); // Get customer groups
+  Future<Map<String, dynamic>> register({...}); // Register new user
+}
+```
+
+**Auth Provider**:
+```dart
+@riverpod
+class Auth extends _$Auth {
+  @override
+  Future<User?> build(); // Initialize session on app startup
+
+  Future<void> login({phoneNumber, password}); // Login flow
+  Future<void> logout(); // Logout and get new public session
+}
+```
+
+**AuthInterceptor**:
+```dart
+class AuthInterceptor extends Interceptor {
+  @override
+  void onRequest(RequestOptions options, RequestInterceptorHandler handler) {
+    // Read from FlutterSecureStorage
+    // Build cookie header
+    // Add to request headers
+  }
+}
+```
+
+---
+
+## Session Storage
+
+All session data is stored in **FlutterSecureStorage** (encrypted):
+
+| Key | Description | Example |
+|-----|-------------|---------|
+| `frappe_sid` | Session ID | "8c39b583..." |
+| `frappe_csrf_token` | CSRF Token | "f8a7754a9ce5..." |
+| `frappe_full_name` | User's full name | "Nguyễn Văn A" |
+| `frappe_user_id` | User ID (phone or email) | "0123456789" or "public_api@dbiz.com" |
+
+---
+
+## Public vs Authenticated Session
+
+### Public Session
+- **User ID**: `public_api@dbiz.com`
+- **Full Name**: "Guest"
+- **Used for**: Registration, loading cities/customer groups
+- **Obtained**: On app startup, after logout
+
+### Authenticated Session
+- **User ID**: User's phone number (e.g., "0123456789")
+- **Full Name**: User's actual name (e.g., "Nguyễn Văn A")
+- **Used for**: All user-specific operations (orders, cart, profile)
+- **Obtained**: After successful login
+
+---
+
+## Error Handling
+
+All API calls use proper exception handling:
+
+- **401 Unauthorized**: `UnauthorizedException` - Session expired or invalid
+- **404 Not Found**: `NotFoundException` - Endpoint not found
+- **Network errors**: `NetworkException` - Connection failed
+- **Validation errors**: `ValidationException` - Invalid data
+
+---
+
+## Future Enhancements
+
+1. **Password Support**: Currently reserved but not sent. When backend supports password:
+   ```dart
+   Future<GetSessionResponse> login({
+     required String phone,
+     required String csrfToken,
+     required String sid,
+     String? password, // Remove nullable, make required
+   }) async {
+     // Add 'password': password to request body
+   }
+   ```
+
+2. **Token Refresh**: Implement automatic token refresh on 401 errors
+
+3. **Session Expiry**: Add session expiry tracking and automatic re-authentication
+
+4. **Biometric Login**: Store phone number and use biometric for quick re-login
+
+---
+
+## Testing the Flow
+
+### 1. Test Public Session
+```dart
+final frappeService = ref.read(frappeAuthServiceProvider).value!;
+final session = await frappeService.getSession();
+print('SID: ${session.sid}');
+print('CSRF: ${session.csrfToken}');
+```
+
+### 2. Test Login
+```dart
+final auth = ref.read(authProvider.notifier);
+await auth.login(
+  phoneNumber: '0123456789',
+  password: 'not_used_yet',
+);
+```
+
+### 3. Test Authenticated Request
+```dart
+final remoteDataSource = ref.read(authRemoteDataSourceProvider).value!;
+final cities = await remoteDataSource.getCities(
+  csrfToken: 'from_storage',
+  sid: 'from_storage',
+);
+```
+
+### 4. Test Logout
+```dart
+await ref.read(authProvider.notifier).logout();
+```
+
+---
+
+## Debugging
+
+Enable cURL logging to see all requests:
+
+**In `dio_client.dart`**:
+```dart
+dio.interceptors.add(CurlLoggerDioInterceptor());
+```
+
+**Console Output**:
+```
+╔══════════════════════════════════════════════════════════════
+║ POST https://land.dbiz.com/api/method/building_material.building_material.api.auth.login
+║ Headers: {Cookie: [HIDDEN], X-Frappe-CSRF-Token: [HIDDEN], ...}
+║ Body: {username: 0123456789, googleid: null, ...}
+╚══════════════════════════════════════════════════════════════
+
+╔══════════════════════════════════════════════════════════════
+║ Response: {session_expired: 1, message: {...}, full_name: Nguyễn Văn A}
+╚══════════════════════════════════════════════════════════════
+```
+
+---
+
+## Summary
+
+The authentication flow is now fully integrated with Frappe/ERPNext:
+
+1. ✅ App startup checks for saved user session
+2. ✅ Public session fetched lazily when needed (via `initializeFrappeSessionProvider`)
+3. ✅ Public session used for cities/customer groups
+4. ✅ Login updates session to authenticated
+5. ✅ All API requests use session from FlutterSecureStorage
+6. ✅ Dio interceptor automatically adds headers
+7. ✅ Logout clears session and gets new public session
+8. ✅ cURL logging for debugging
+9. ✅ No provider disposal errors
+
+All session management is centralized in `FrappeAuthService` with automatic integration via `AuthInterceptor`.**

+
+## Usage Example
+
+### Update Cart Provider to Use Repository
+
+```dart
+@riverpod
+class Cart extends _$Cart {
+  CartRepository get _repository => ref.read(cartRepositoryProvider);
+
+  @override
+  CartState build() {
+    // Load cart items from API on initialization
+    _loadCartItems();
+    return CartState.initial();
+  }
+
+  Future<void> _loadCartItems() async {
+    try {
+      final items = await _repository.getCartItems();
+      // Convert domain entities to UI state
+      state = state.copyWith(items: _convertToCartItemData(items));
+    } catch (e) {
+      // Handle error
+    }
+  }
+
+  Future<void> addToCart(Product product, {double quantity = 1.0}) async {
+    try {
+      // Call repository with ERPNext item code
+      final items = await _repository.addToCart(
+        itemIds: [product.erpnextItemCode ?? product.productId],
+        quantities: [quantity],
+        prices: [product.basePrice],
+      );
+
+      // Update UI state
+      state = state.copyWith(items: _convertToCartItemData(items));
+    } on NetworkException catch (e) {
+      // Show error to user
+      _showError(e.message);
+    } catch (e) {
+      _showError('Failed to add item to cart');
+    }
+  }
+
+  Future<void> removeFromCart(String productId) async {
+    try {
+      await _repository.removeFromCart(itemIds: [productId]);
+
+      // Update UI state
+      final updatedItems = state.items
+          .where((item) => item.product.productId != productId)
+          .toList();
+      state = state.copyWith(items: updatedItems);
+    } catch (e) {
+      _showError('Failed to remove item from cart');
+    }
+  }
+
+  List<CartItemData> _convertToCartItemData(List<CartItem> entities) {
+    // Convert domain entities to UI data models
+    // You'll need to fetch Product entities for each CartItem
+    // This is left as TODO
+    return [];
+  }
+
+  void _showError(String message) {
+    // Show SnackBar or error dialog
+  }
+}
+```
+
+## Important Notes
+
+### Product ID Mapping
+- **UI Layer**: Uses `product.productId` (UUID)
+- **API Layer**: Expects `item_id` (ERPNext code)
+- **Always use**: `product.erpnextItemCode ?? product.productId`
+
+### Hive Best Practice
+```dart
+// CORRECT: Use Box<dynamic> with .whereType<T>()
+Box<dynamic> get _cartBox => _hiveService.getBox<dynamic>(HiveBoxNames.cartBox);
+
+final items = _cartBox.values
+    .whereType<CartItemModel>()
+    .toList();
+
+// WRONG: Don't use Box<CartItemModel>
+// This causes HiveError when box is already open as Box<dynamic>
+```
+
+### Error Handling Pattern
+```dart
+try {
+  // Try operation
+  await _repository.addToCart(...);
+} on StorageException {
+  rethrow; // Let caller handle
+} on NetworkException {
+  rethrow; // Let caller handle
+} on ServerException {
+  rethrow; // Let caller handle
+} on ValidationException {
+  rethrow; // Let caller handle
+} catch (e) {
+  // Wrap unknown errors
+  throw UnknownException('Operation failed', e);
+}
+```
+

+- Use `cartRepositoryProvider`
+- Call API methods instead of local-only state
+- Handle async operations
+- Show loading states
+- Display error messages
+
+### 2. Implement Offline Queue (MEDIUM PRIORITY)
+- Create offline queue service

+
+## Quick Usage
+
+### 1. Import the Repository
+
+```dart
+import 'package:worker/features/cart/data/repositories/cart_repository_impl.dart';
+import 'package:worker/features/cart/domain/entities/cart_item.dart';
+```
+
+### 2. Use in Your Provider
+
+```dart
+@riverpod
+class Cart extends _$Cart {
+  CartRepository get _repository => ref.read(cartRepositoryProvider);
+
+  // Add to cart
+  Future<void> addProductToCart(Product product, double quantity) async {
+    try {
+      final items = await _repository.addToCart(
+        itemIds: [product.erpnextItemCode ?? product.productId],
+        quantities: [quantity],
+        prices: [product.basePrice],
+      );
+      // Update UI state with items
+    } catch (e) {
+      // Show error
+    }
+  }
+
+  // Get cart items
+  Future<void> loadCart() async {
+    try {
+      final items = await _repository.getCartItems();
+      // Update UI state with items
+    } catch (e) {
+      // Show error
+    }
+  }
+
+  // Remove from cart
+  Future<void> removeProduct(String itemId) async {
+    try {
+      await _repository.removeFromCart(itemIds: [itemId]);
+      // Update UI state
+    } catch (e) {
+      // Show error
+    }
+  }
+}
+```
+
+## API Methods Available
+
+```dart
+// Add items to cart (replaces/updates existing)
+Future<List<CartItem>> addToCart({
+  required List<String> itemIds,      // ERPNext item codes
+  required List<double> quantities,
+  required List<double> prices,
+});
+
+// Remove items from cart
+Future<bool> removeFromCart({
+  required List<String> itemIds,
+});
+
+// Get all cart items
+Future<List<CartItem>> getCartItems();
+
+// Update quantity (uses addToCart internally)
+Future<List<CartItem>> updateQuantity({
+  required String itemId,
+  required double quantity,
+  required double price,
+});
+
+// Clear entire cart
+Future<bool> clearCart();
+
+// Get cart total
+Future<double> getCartTotal();
+
+// Get cart item count
+Future<int> getCartItemCount();
+```
+
+## Error Handling
+
+All methods can throw:
+- `NoInternetException` - No network connection
+- `TimeoutException` - Request timeout
+- `UnauthorizedException` - 401 auth error
+- `ForbiddenException` - 403 permission error
+- `NotFoundException` - 404 not found
+- `ServerException` - 5xx server error
+- `NetworkException` - Other network errors
+- `StorageException` - Local storage error
+- `ValidationException` - Invalid input
+- `UnknownException` - Unexpected error
+
+## Important Notes
+
+### Product ID Mapping
+```dart
+// ALWAYS use erpnextItemCode for API calls
+final itemId = product.erpnextItemCode ?? product.productId;
+
+await _repository.addToCart(
+  itemIds: [itemId],  // ERPNext code, not UUID
+  quantities: [quantity],
+  prices: [product.basePrice],
+);
+```
+
+### Offline Support
+- Read operations fallback to local storage when offline
+- Write operations save locally and queue for sync (TODO)
+- Cart persists across app restarts
+
+### Response Format
+Methods return domain `CartItem` entities:
+```dart
+class CartItem {
+  final String cartItemId;
+  final String cartId;
+  final String productId;      // ERPNext item code
+  final double quantity;
+  final double unitPrice;
+  final double subtotal;
+  final DateTime addedAt;
+}
+```
+
+## Common Patterns
+
+### Add Product to Cart
+```dart
+void onAddToCart(Product product) async {
+  try {
+    setState(() => _isLoading = true);
+
+    await _repository.addToCart(
+      itemIds: [product.erpnextItemCode ?? product.productId],
+      quantities: [1.0],
+      prices: [product.basePrice],
+    );
+
+    // Show success
+    ScaffoldMessenger.of(context).showSnackBar(
+      SnackBar(content: Text('Added to cart')),
+    );
+  } catch (e) {
+    // Show error
+    ScaffoldMessenger.of(context).showSnackBar(
+      SnackBar(content: Text('Failed to add to cart')),
+    );
+  } finally {
+    setState(() => _isLoading = false);
+  }
+}
+```
+
+### Load Cart on Page Open
+```dart
+@override
+void initState() {
+  super.initState();
+  _loadCart();
+}
+
+Future<void> _loadCart() async {
+  try {
+    final items = await ref.read(cartRepositoryProvider).getCartItems();
+    // Update state
+  } catch (e) {
+    // Handle error
+  }
+}
+```
+
+### Update Quantity
+```dart
+Future<void> onQuantityChanged(String itemId, double newQuantity, double price) async {
+  try {
+    await _repository.updateQuantity(
+      itemId: itemId,
+      quantity: newQuantity,
+      price: price,
+    );
+    // Reload cart
+    await loadCart();
+  } catch (e) {
+    // Show error
+  }
+}
+```
+
+### Remove Item
+```dart
+Future<void> onRemoveItem(String itemId) async {
+  try {
+    await _repository.removeFromCart(itemIds: [itemId]);
+    // Reload cart
+    await loadCart();
+  } catch (e) {
+    // Show error
+  }
+}
+```
+
+## Testing
+
+Run tests with:
+```bash
+flutter test
+```
+
+Test files location:
+- `/Users/ssg/project/worker/test/features/cart/`
+
+## Troubleshooting
+
+### Issue: "Box is already open and of type Box<dynamic>"
+**Solution**: The datasource already uses `Box<dynamic>`. Don't re-open boxes with specific types.
+
+### Issue: "Network error" on every request
+**Solution**: Check if user is authenticated. Cart endpoints require valid session.
+
+### Issue: Items not syncing to API
+**Solution**: Check network connection. Items save locally when offline.
+
+### Issue: "ProductId not found in cart"
+**Solution**: Use ERPNext item code, not product UUID. Check `product.erpnextItemCode`.
+
+## Next Steps
+
+1. Update existing `cart_provider.dart` to use repository
+2. Add loading states to cart UI
+3. Add error messages with SnackBar
+4. Test all cart operations
+5. Implement offline queue (optional)

+# Cart Feature - Key Code Reference
+
+## 1. Adding Item to Cart with Conversion
+
+```dart
+// In cart_provider.dart
+void addToCart(Product product, {double quantity = 1.0}) {
+  // Calculate conversion
+  final converted = _calculateConversion(quantity);
+  
+  // Create cart item with conversion data
+  final newItem = CartItemData(
+    product: product,
+    quantity: quantity,                    // User input: 10
+    quantityConverted: converted.convertedQuantity,  // Billing: 10.08
+    boxes: converted.boxes,                // Tiles: 28
+  );
+  
+  // Add to cart and auto-select
+  final updatedSelection = Map<String, bool>.from(state.selectedItems);
+  updatedSelection[product.productId] = true;
+  
+  state = state.copyWith(
+    items: [...state.items, newItem],
+    selectedItems: updatedSelection,
+  );
+}
+
+// Conversion calculation (mock - replace with backend)
+({double convertedQuantity, int boxes}) _calculateConversion(double quantity) {
+  final converted = (quantity * 1.008 * 100).ceilToDouble() / 100;
+  final boxes = (quantity * 2.8).ceil();
+  return (convertedQuantity: converted, boxes: boxes);
+}
+```
+
+## 2. Cart Item Widget with Checkbox
+
+```dart
+// In cart_item_widget.dart
+Row(
+  crossAxisAlignment: CrossAxisAlignment.start,
+  children: [
+    // Checkbox (aligned to top)
+    Padding(
+      padding: const EdgeInsets.only(top: 34),
+      child: _CustomCheckbox(
+        value: isSelected,
+        onChanged: (value) {
+          ref.read(cartProvider.notifier).toggleSelection(item.product.productId);
+        },
+      ),
+    ),
+    
+    const SizedBox(width: 12),
+    
+    // Product Image
+    ClipRRect(...),
+    
+    const SizedBox(width: 12),
+    
+    // Product Info with Conversion
+    Expanded(
+      child: Column(
+        children: [
+          Text(item.product.name),
+          Text('${price}/${unit}'),
+          
+          // Quantity Controls
+          Row([
+            _QuantityButton(icon: Icons.remove, onPressed: decrement),
+            Text(quantity),
+            _QuantityButton(icon: Icons.add, onPressed: increment),
+            Text(unit),
+          ]),
+          
+          // Conversion Display
+          RichText(
+            text: TextSpan(
+              children: [
+                TextSpan(text: '(Quy đổi: '),
+                TextSpan(
+                  text: '${item.quantityConverted.toStringAsFixed(2)} m²',
+                  style: TextStyle(fontWeight: FontWeight.bold),
+                ),
+                TextSpan(text: ' = '),
+                TextSpan(
+                  text: '${item.boxes} viên',
+                  style: TextStyle(fontWeight: FontWeight.bold),
+                ),
+                TextSpan(text: ')'),
+              ],
+            ),
+          ),
+        ],
+      ),
+    ),
+  ],
+)
+```
+
+## 3. Select All Section
+
+```dart
+// In cart_page.dart
+Container(
+  child: Row(
+    mainAxisAlignment: MainAxisAlignment.spaceBetween,
+    children: [
+      // Left: Checkbox + Label
+      GestureDetector(
+        onTap: () => ref.read(cartProvider.notifier).toggleSelectAll(),
+        child: Row(
+          children: [
+            _CustomCheckbox(
+              value: cartState.isAllSelected,
+              onChanged: (value) => ref.read(cartProvider.notifier).toggleSelectAll(),
+            ),
+            const SizedBox(width: 12),
+            Text('Chọn tất cả'),
+          ],
+        ),
+      ),
+      
+      // Right: Selected Count
+      Text('Đã chọn: ${cartState.selectedCount}/${cartState.itemCount}'),
+    ],
+  ),
+)
+```
+
+## 4. Sticky Footer
+
+```dart
+// In cart_page.dart
+Positioned(
+  bottom: 0,
+  left: 0,
+  right: 0,
+  child: Container(
+    decoration: BoxDecoration(
+      color: AppColors.white,
+      border: Border(top: BorderSide(...)),
+      boxShadow: [...],
+    ),
+    child: SafeArea(
+      child: Row(
+        children: [
+          // Delete Button (48x48)
+          InkWell(
+            onTap: hasSelection ? deleteSelected : null,
+            child: Container(
+              width: 48,
+              height: 48,
+              decoration: BoxDecoration(
+                border: Border.all(color: AppColors.danger, width: 2),
+                borderRadius: BorderRadius.circular(10),
+              ),
+              child: Icon(Icons.delete_outline),
+            ),
+          ),
+          
+          const SizedBox(width: 16),
+          
+          // Total Info
+          Expanded(
+            child: Column(
+              children: [
+                Text('Tổng tạm tính (${selectedCount} sản phẩm)'),
+                Text(currencyFormatter.format(selectedTotal)),
+              ],
+            ),
+          ),
+          
+          const SizedBox(width: 16),
+          
+          // Checkout Button
+          ElevatedButton(
+            onPressed: hasSelection ? checkout : null,
+            child: Text('Tiến hành đặt hàng'),
+          ),
+        ],
+      ),
+    ),
+  ),
+)
+```
+
+## 5. Selection Logic in Provider
+
+```dart
+// Toggle single item
+void toggleSelection(String productId) {
+  final updatedSelection = Map<String, bool>.from(state.selectedItems);
+  updatedSelection[productId] = !(updatedSelection[productId] ?? false);
+  state = state.copyWith(selectedItems: updatedSelection);
+  _recalculateTotal();
+}
+
+// Toggle all items
+void toggleSelectAll() {
+  final allSelected = state.isAllSelected;
+  final updatedSelection = <String, bool>{};
+  for (final item in state.items) {
+    updatedSelection[item.product.productId] = !allSelected;
+  }
+  state = state.copyWith(selectedItems: updatedSelection);
+  _recalculateTotal();
+}
+
+// Delete selected
+void deleteSelected() {
+  final selectedIds = state.selectedItems.entries
+      .where((entry) => entry.value)
+      .map((entry) => entry.key)
+      .toSet();
+
+  final remainingItems = state.items
+      .where((item) => !selectedIds.contains(item.product.productId))
+      .toList();
+
+  final updatedSelection = Map<String, bool>.from(state.selectedItems);
+  for (final id in selectedIds) {
+    updatedSelection.remove(id);
+  }
+
+  state = state.copyWith(
+    items: remainingItems,
+    selectedItems: updatedSelection,
+  );
+  _recalculateTotal();
+}
+```
+
+## 6. Recalculate Total (Selected Items Only)
+
+```dart
+void _recalculateTotal() {
+  // Only include selected items
+  double subtotal = 0.0;
+  for (final item in state.items) {
+    if (state.selectedItems[item.product.productId] == true) {
+      subtotal += item.lineTotal; // Uses quantityConverted
+    }
+  }
+
+  final memberDiscount = subtotal * (state.memberDiscountPercent / 100);
+  const shippingFee = 0.0;
+  final total = subtotal - memberDiscount + shippingFee;
+
+  state = state.copyWith(
+    subtotal: subtotal,
+    memberDiscount: memberDiscount,
+    shippingFee: shippingFee,
+    total: total,
+  );
+}
+```
+
+## 7. Payment Method Options
+
+```dart
+// Full Payment
+Radio<String>(
+  value: 'full_payment',
+  groupValue: paymentMethod.value,
+  onChanged: (value) => paymentMethod.value = value!,
+),
+const Column(
+  children: [
+    Text('Thanh toán hoàn toàn'),
+    Text('Thanh toán qua tài khoản ngân hàng'),
+  ],
+),
+
+// Partial Payment
+Radio<String>(
+  value: 'partial_payment',
+  groupValue: paymentMethod.value,
+  onChanged: (value) => paymentMethod.value = value!,
+),
+const Column(
+  children: [
+    Text('Thanh toán một phần'),
+    Text('Trả trước(≥20%), còn lại thanh toán trong vòng 30 ngày'),
+  ],
+),
+```
+
+## 8. Order Summary with Conversion
+
+```dart
+// Item display in checkout
+Row(
+  children: [
+    Expanded(
+      child: Column(
+        crossAxisAlignment: CrossAxisAlignment.start,
+        children: [
+          // Line 1: Product name
+          Text(item['name']),
+          
+          // Line 2: Conversion (muted)
+          Text(
+            '$quantityM2 m² ($boxes viên / ${quantityConverted.toStringAsFixed(2)} m²)',
+            style: TextStyle(color: AppColors.grey500),
+          ),
+        ],
+      ),
+    ),
+    
+    // Price (using converted quantity)
+    Text(_formatCurrency(price * quantityConverted)),
+  ],
+)
+```
+
+## 9. Custom Checkbox Widget
+
+```dart
+class _CustomCheckbox extends StatelessWidget {
+  final bool value;
+  final ValueChanged<bool?>? onChanged;
+
+  @override
+  Widget build(BuildContext context) {
+    return GestureDetector(
+      onTap: () => onChanged?.call(!value),
+      child: Container(
+        width: 22,
+        height: 22,
+        decoration: BoxDecoration(
+          color: value ? AppColors.primaryBlue : AppColors.white,
+          border: Border.all(
+            color: value ? AppColors.primaryBlue : Color(0xFFCBD5E1),
+            width: 2,
+          ),
+          borderRadius: BorderRadius.circular(6),
+        ),
+        child: value
+            ? Icon(Icons.check, size: 16, color: AppColors.white)
+            : null,
+      ),
+    );
+  }
+}
+```
+
+## 10. Delete Confirmation Dialog
+
+```dart
+void _showDeleteConfirmation(BuildContext context, WidgetRef ref, CartState cartState) {
+  showDialog<void>(
+    context: context,
+    builder: (context) => AlertDialog(
+      title: const Text('Xóa sản phẩm'),
+      content: Text('Bạn có chắc muốn xóa ${cartState.selectedCount} sản phẩm đã chọn?'),
+      actions: [
+        TextButton(
+          onPressed: () => context.pop(),
+          child: const Text('Hủy'),
+        ),
+        ElevatedButton(
+          onPressed: () {
+            ref.read(cartProvider.notifier).deleteSelected();
+            context.pop();
+            ScaffoldMessenger.of(context).showSnackBar(
+              const SnackBar(
+                content: Text('Đã xóa sản phẩm khỏi giỏ hàng'),
+                backgroundColor: AppColors.success,
+              ),
+            );
+          },
+          style: ElevatedButton.styleFrom(backgroundColor: AppColors.danger),
+          child: const Text('Xóa'),
+        ),
+      ],
+    ),
+  );
+}
+```
+
+## CSS/Flutter Equivalents

+# Cart Quantity Update Debounce Implementation
+
+## Overview
+Implemented a 3-second debounce for cart quantity updates to prevent excessive API calls. UI updates happen instantly, but API sync is delayed until the user stops changing quantities.
+
+## Problem Solved
+**Before**: Every increment/decrement button press triggered an immediate API call
+- Multiple rapid clicks = multiple API calls
+- Poor performance and UX
+- Unnecessary server load
+- Potential rate limiting issues
+
+**After**: UI updates instantly, API syncs after 3 seconds of inactivity
+- User can rapidly change quantities
+- Only one API call after user stops
+- Smooth, responsive UI
+- Reduced server load
+
+## Implementation Details
+
+### 1. Debounce Timer in Cart Provider
+**File**: `lib/features/cart/presentation/providers/cart_provider.dart`
+
+```dart
+@Riverpod(keepAlive: true)
+class Cart extends _$Cart {
+  /// Debounce timer for quantity updates (3 seconds)
+  Timer? _debounceTimer;
+
+  /// Map to track pending quantity updates (productId -> quantity)
+  final Map<String, double> _pendingQuantityUpdates = {};
+
+  @override
+  CartState build() {
+    // Cancel debounce timer when provider is disposed
+    ref.onDispose(() {
+      _debounceTimer?.cancel();
+    });
+
+    return CartState.initial().copyWith(
+      memberTier: 'Diamond',
+      memberDiscountPercent: 15.0,
+    );
+  }
+}
+```
+
+### 2. Local Update Method (Instant UI Update)
+
+```dart
+/// Update item quantity immediately (local only, no API call)
+///
+/// Used for instant UI updates. Actual API sync happens after debounce.
+void updateQuantityLocal(String productId, double newQuantity) {
+  if (newQuantity <= 0) {
+    removeFromCart(productId);
+    return;
+  }
+
+  final currentState = state;
+  final itemIndex = currentState.items.indexWhere(
+    (item) => item.product.productId == productId,
+  );
+
+  if (itemIndex == -1) return;
+  final item = currentState.items[itemIndex];
+
+  // Update local state immediately (instant UI update)
+  final converted = _calculateConversion(
+    newQuantity,
+    item.product.conversionOfSm,
+  );
+
+  final updatedItems = List<CartItemData>.from(currentState.items);
+  updatedItems[itemIndex] = item.copyWith(
+    quantity: newQuantity,
+    quantityConverted: converted.convertedQuantity,
+    boxes: converted.boxes,
+  );
+
+  final newState = currentState.copyWith(items: updatedItems);
+  state = _recalculateTotal(newState);
+
+  // Track pending update for API sync
+  _pendingQuantityUpdates[productId] = newQuantity;
+
+  // Schedule debounced API sync
+  _scheduleDebouncedSync();
+}
+```
+
+### 3. Debounce Scheduling
+
+```dart
+/// Schedule debounced sync to API (3 seconds after last change)
+void _scheduleDebouncedSync() {
+  // Cancel existing timer (restarts the 3s countdown)
+  _debounceTimer?.cancel();
+
+  // Start new timer (3 seconds debounce)
+  _debounceTimer = Timer(const Duration(seconds: 3), () {
+    _syncPendingQuantityUpdates();
+  });
+}
+```
+
+### 4. Background API Sync
+
+```dart
+/// Sync all pending quantity updates to API
+Future<void> _syncPendingQuantityUpdates() async {
+  if (_pendingQuantityUpdates.isEmpty) return;
+
+  final repository = await ref.read(cartRepositoryProvider.future);
+  final currentState = state;
+
+  // Create a copy of pending updates
+  final updates = Map<String, double>.from(_pendingQuantityUpdates);
+  _pendingQuantityUpdates.clear();
+
+  // Sync each update to API (background, no loading state)
+  for (final entry in updates.entries) {
+    final productId = entry.key;
+    final quantity = entry.value;
+
+    final item = currentState.items.firstWhere(
+      (item) => item.product.productId == productId,
+      orElse: () => throw Exception('Item not found'),
+    );
+
+    try {
+      await repository.updateQuantity(
+        itemId: item.product.erpnextItemCode ?? productId,
+        quantity: quantity,
+        price: item.product.basePrice,
+      );
+    } catch (e) {
+      // Silent fail - keep local state, user can retry later
+      print('[Cart] Failed to sync quantity for $productId: $e');
+    }
+  }
+}
+```
+
+### 5. Updated Increment/Decrement Methods
+
+```dart
+/// Increment quantity (with debounce)
+///
+/// Updates UI immediately, syncs to API after 3s of no changes.
+void incrementQuantity(String productId) {
+  final currentState = state;
+  final item = currentState.items.firstWhere(
+    (item) => item.product.productId == productId,
+  );
+  updateQuantityLocal(productId, item.quantity + 1);
+}
+
+/// Decrement quantity (minimum 1, with debounce)
+///
+/// Updates UI immediately, syncs to API after 3s of no changes.
+void decrementQuantity(String productId) {
+  final currentState = state;
+  final item = currentState.items.firstWhere(
+    (item) => item.product.productId == productId,
+  );
+  // Keep minimum quantity at 1, don't go to 0
+  if (item.quantity > 1) {
+    updateQuantityLocal(productId, item.quantity - 1);
+  }
+}
+```
+
+### 6. Force Sync on Navigation & Checkout
+
+**File**: `lib/features/cart/presentation/pages/cart_page.dart`
+
+#### A. Force Sync on Page Disposal
+```dart
+class _CartPageState extends ConsumerState<CartPage> {
+  @override
+  void dispose() {
+    // Force sync any pending quantity updates before leaving cart page
+    ref.read(cartProvider.notifier).forceSyncPendingUpdates();
+    super.dispose();
+  }
+}
+```
+
+#### B. Force Sync on Checkout Button (Skip Debounce) ⚡
+```dart
+class _CartPageState extends ConsumerState<CartPage> {
+  bool _isSyncing = false;
+
+  @override
+  Widget build(BuildContext context) {
+    return ElevatedButton(
+      onPressed: hasSelection && !_isSyncing
+          ? () async {
+              // Set syncing state (show loading)
+              setState(() {
+                _isSyncing = true;
+              });
+
+              // Force sync immediately - NO WAITING for debounce!
+              await ref
+                  .read(cartProvider.notifier)
+                  .forceSyncPendingUpdates();
+
+              // Reset syncing state
+              if (mounted) {
+                setState(() {
+                  _isSyncing = false;
+                });
+
+                // Navigate to checkout with synced data
+                context.push(RouteNames.checkout);
+              }
+            }
+          : null,
+      child: _isSyncing
+          ? const CustomLoadingIndicator() // Show loading while syncing
+          : Text('Tiến hành đặt hàng'),
+    );
+  }
+}
+```
+
+**Provider Method**:
+```dart
+/// Force sync all pending quantity updates immediately
+///
+/// Useful when:
+/// - User taps checkout button (skip 3s debounce)
+/// - User navigates away or closes cart
+/// - Need to ensure data is synced before critical operations
+Future<void> forceSyncPendingUpdates() async {
+  _debounceTimer?.cancel();
+  await _syncPendingQuantityUpdates();
+}
+```
+
+## User Flow
+
+### Scenario 1: Rapid Clicks (Debounced)
+```
+User clicks +5 times rapidly (within 3 seconds)
+  ↓
+Each click: UI updates instantly (1→2→3→4→5)
+  ↓
+Timer restarts on each click
+  ↓
+User stops clicking
+  ↓
+3 seconds pass
+  ↓
+Single API call: updateQuantity(productId, 5)
+```
+
+### Scenario 2: Manual Text Input (Immediate)
+```
+User types "10" in quantity field
+  ↓
+User presses Enter
+  ↓
+Immediate API call: updateQuantity(productId, 10)
+  ↓
+No debounce (direct input needs immediate sync)
+```
+
+### Scenario 3: Navigate Away (Force Sync)
+```
+User clicks + button 3 times
+  ↓
+UI updates: 1→2→3
+  ↓
+Timer is running (1 second passed)
+  ↓
+User navigates back
+  ↓
+dispose() called
+  ↓
+forceSyncPendingUpdates() executes
+  ↓
+Immediate API call: updateQuantity(productId, 3)
+```
+
+### Scenario 4: Checkout Button (Force Sync - Skip Debounce) ⚡ NEW
+```
+User clicks + button 5 times
+  ↓
+UI updates: 1→2→3→4→5
+  ↓
+Timer is running (1 second passed, would wait 2 more seconds)
+  ↓
+User clicks "Tiến hành đặt hàng" (Checkout)
+  ↓
+Button shows loading spinner
+  ↓
+forceSyncPendingUpdates() called IMMEDIATELY
+  ↓
+Debounce timer cancelled
+  ↓
+API call: updateQuantity(productId, 5) - NO WAITING!
+  ↓
+Navigate to checkout page with synced data ✅
+```
+
+## Benefits
+
+✅ **Instant UI feedback** - No waiting for API responses
+✅ **Reduced API calls** - Only 1 call per product after changes stop
+✅ **Better UX** - Smooth, responsive interface
+✅ **Server-friendly** - Minimizes unnecessary requests
+✅ **Offline-ready** - Local state updates work offline
+✅ **Force sync on exit** - Ensures changes are saved
+✅ **Skip debounce on checkout** - Immediate sync when user clicks checkout ⚡ NEW
+
+## Configuration
+
+### Debounce Duration
+Default: **3 seconds** ✅
+
+To change:
+```dart
+_debounceTimer = Timer(const Duration(seconds: 3), () {
+  _syncPendingQuantityUpdates();
+});
+```
+
+Recommended values:
+- **2-3 seconds**: Responsive, good balance (current setting) ✅
+- **5 seconds**: More conservative (fewer API calls)
+- **1 second**: Very aggressive (more API calls, but faster sync)
+
+## Testing
+
+### Manual Testing
+1. **Test rapid clicks**:
+   - Open cart
+   - Click + button 10 times rapidly
+   - Watch console: Should see only 1 API call after 3s
+
+2. **Test text input**:
+   - Type quantity directly
+   - Press Enter
+   - Should see immediate API call
+
+3. **Test navigation sync**:
+   - Click + button 3 times
+   - Immediately navigate back
+   - Should see API call before page closes
+
+4. **Test multiple products**:
+   - Change quantity on product A
+   - Change quantity on product B
+   - Wait 3 seconds
+   - Should batch update both products
+
+5. **Test checkout force sync** ⚡ NEW:
+   - Click + button 5 times rapidly
+   - Immediately click "Tiến hành đặt hàng" (within 3s)
+   - Button should show loading spinner
+   - API call should happen immediately (skip debounce)
+   - Should navigate to checkout with synced data
+
+### Expected Behavior
+```
+// Rapid increments (debounced)
+Click +1 → UI: 2, API: none
+Click +1 → UI: 3, API: none
+Click +1 → UI: 4, API: none
+Wait 3s → UI: 4, API: updateQuantity(4) ✅
+
+// Direct input (immediate)
+Type "10" → UI: 10, API: none
+Press Enter → UI: 10, API: updateQuantity(10) ✅
+
+// Navigate away (force sync)
+Click +1 → UI: 2, API: none
+Navigate back → UI: 2, API: updateQuantity(2) ✅
+
+// Checkout button (force sync - skip debounce) ⚡ NEW
+Click +5 times → UI: 1→2→3→4→5, API: none
+Click checkout (after 1s) → Loading spinner shown
+→ API: updateQuantity(5) IMMEDIATELY (skip remaining 2s debounce)
+→ Navigate to checkout ✅
+```
+
+## Error Handling
+
+### API Sync Failure
+- Local state is preserved
+- User sees correct quantity in UI
+- Error is logged silently
+- User can retry by refreshing cart
+
+### Offline Behavior
+- All updates work in local state
+- API calls fail silently
+- TODO: Add to offline queue for retry when online
+
+## Performance Impact
+
+### Before Debounce
+- 10 rapid clicks = 10 API calls
+- Each call takes ~200-500ms
+- Total time: 2-5 seconds of loading
+- Poor UX, server strain
+
+### After Debounce
+- 10 rapid clicks = 1 API call (after 3s)
+- UI updates are instant (<16ms per frame)
+- Total time: 3 seconds wait + 1 API call
+- Great UX, minimal server load
+
+## Future Enhancements
+
+1. **Batch Updates**: Combine multiple product updates into single API call
+2. **Offline Queue**: Persist pending updates to Hive for offline resilience
+3. **Visual Indicator**: Show "syncing..." badge when pending updates exist
+4. **Configurable Timeout**: Allow users to adjust debounce duration
+5. **Smart Sync**: Sync immediately before checkout/payment

+# Cart Initialization & Keep Alive Implementation
+
+## Overview
+The cart is now initialized when the app starts (on HomePage mount) and kept alive throughout the entire app session. This ensures:
+- Cart data is loaded from API once on startup
+- Cart state persists across all navigation
+- No unnecessary re-fetching when navigating between pages
+- Real-time cart badge updates across all screens
+
+## Implementation Details
+
+### 1. Cart Provider with Keep Alive
+**File**: `lib/features/cart/presentation/providers/cart_provider.dart`
+
+```dart
+@Riverpod(keepAlive: true)  // ✅ Keep alive throughout app session
+class Cart extends _$Cart {
+  @override
+  CartState build() {
+    return CartState.initial().copyWith(
+      memberTier: 'Diamond',
+      memberDiscountPercent: 15.0,
+    );
+  }
+
+  Future<void> initialize() async {
+    // Load cart from API with Hive fallback
+    // ...
+  }
+}
+
+// Dependent providers also need keepAlive
+@Riverpod(keepAlive: true)
+int cartItemCount(Ref ref) {
+  final cartState = ref.watch(cartProvider);
+  return cartState.items.length;
+}
+
+@Riverpod(keepAlive: true)
+double cartTotal(Ref ref) {
+  final cartState = ref.watch(cartProvider);
+  return cartState.total;
+}
+```
+
+### 1.1 Cart Data Providers with Keep Alive
+**File**: `lib/features/cart/data/providers/cart_data_providers.dart`
+
+**CRITICAL**: All cart data layer providers must also use `keepAlive: true` to prevent disposal errors:
+
+```dart
+@Riverpod(keepAlive: true)
+CartLocalDataSource cartLocalDataSource(Ref ref) {
+  final hiveService = HiveService();
+  return CartLocalDataSourceImpl(hiveService);
+}
+
+@Riverpod(keepAlive: true)
+Future<CartRemoteDataSource> cartRemoteDataSource(Ref ref) async {
+  final dioClient = await ref.watch(dioClientProvider.future);
+  return CartRemoteDataSourceImpl(dioClient);
+}
+
+@Riverpod(keepAlive: true)
+Future<CartRepository> cartRepository(Ref ref) async {
+  final remoteDataSource = await ref.watch(cartRemoteDataSourceProvider.future);
+  final localDataSource = ref.watch(cartLocalDataSourceProvider);
+  return CartRepositoryImpl(
+    remoteDataSource: remoteDataSource,
+    localDataSource: localDataSource,
+  );
+}
+```
+
+**Why all providers need keepAlive:**
+- Cart provider depends on cartRepository
+- If repository is disposed, cart operations fail with "Ref disposed" error
+- All dependencies in the chain must persist together
+- Ensures consistent lifecycle management
+
+**Benefits of `keepAlive: true`:**
+- Provider state is never disposed
+- Cart data persists when navigating away and back
+- No re-initialization needed on subsequent visits
+- Consistent cart count across all app screens
+- No "Ref disposed" errors during async operations
+
+### 2. HomePage Initialization
+**File**: `lib/features/home/presentation/pages/home_page.dart`
+
+```dart
+class HomePage extends ConsumerStatefulWidget {
+  const HomePage({super.key});
+
+  @override
+  ConsumerState<HomePage> createState() => _HomePageState();
+}
+
+class _HomePageState extends ConsumerState<HomePage> {
+  @override
+  void initState() {
+    super.initState();
+    // Initialize cart from API on app startup
+    WidgetsBinding.instance.addPostFrameCallback((_) {
+      ref.read(cartProvider.notifier).initialize();
+    });
+  }
+
+  @override
+  Widget build(BuildContext context) {
+    // Watch cart item count for badge
+    final cartItemCount = ref.watch(cartItemCountProvider);
+    // ...
+  }
+}
+```
+
+**Why in HomePage?**
+- HomePage is the first screen after login
+- Ensures cart is loaded early in app lifecycle
+- Provides immediate cart count for navigation badge
+
+### 3. Cart Badge Integration
+**Location**: All pages with cart icon/badge
+
+```dart
+// Any page can watch cart count - it's always available
+final cartItemCount = ref.watch(cartItemCountProvider);
+
+// Display badge
+if (cartItemCount > 0)
+  Badge(
+    label: Text('$cartItemCount'),
+    child: Icon(Icons.shopping_cart),
+  )
+```
+
+## Data Flow
+
+```
+App Start
+    ↓
+HomePage mounts
+    ↓
+initState() calls cart.initialize()
+    ↓
+Cart loads from API → Syncs to Hive
+    ↓
+Cart state updates with items
+    ↓
+cartItemCountProvider updates
+    ↓
+All badges across app update reactively
+    ↓
+[keepAlive ensures state persists during navigation]
+```
+
+## API & Local Storage Integration
+
+### Initialize Flow
+1. **API First**: Fetch cart items from ERPNext API
+2. **Product Details**: For each cart item, fetch full product data
+3. **Calculate Conversions**: Apply business rules (boxes, m², etc.)
+4. **Update State**: Set cart items with full product info
+5. **Local Sync**: Automatically synced to Hive by repository
+
+### Offline Fallback
+- If API fails, cart loads from Hive cache
+- All mutations queue for sync when online
+- See `cart_repository_impl.dart` for sync logic
+
+## Cart Operations
+
+All cart operations work seamlessly after initialization:
+
+```dart
+// Add to cart (from any page)
+await ref.read(cartProvider.notifier).addToCart(product, quantity: 2.0);
+
+// Remove from cart
+await ref.read(cartProvider.notifier).removeFromCart(productId);
+
+// Update quantity
+await ref.read(cartProvider.notifier).updateQuantity(productId, 5.0);
+
+// Clear cart
+await ref.read(cartProvider.notifier).clearCart();
+```
+
+All operations:
+- Sync to API first
+- Fallback to local on failure
+- Queue for sync when offline
+- Update UI reactively
+
+## Testing Keep Alive
+
+To verify keepAlive works:
+
+1. **Navigate to HomePage** → Cart initializes
+2. **Add items to cart** → Badge shows count
+3. **Navigate to Products page** → Badge still shows count
+4. **Navigate back to HomePage** → Cart state preserved, no re-fetch
+5. **Navigate to Cart page** → Same items, no loading
+6. **Hot restart app** → Cart reloads from API
+
+## Performance Benefits
+
+- **One-time API call**: Cart loads once on startup
+- **No re-fetching**: Navigation doesn't trigger reloads
+- **Instant updates**: All cart operations update state immediately
+- **Offline support**: Hive cache provides instant fallback
+- **Memory efficient**: Single provider instance for entire app
+
+## Error Handling
+
+If cart initialization fails:
+- Error stored in `cartState.errorMessage`
+- Can retry via `ref.read(cartProvider.notifier).initialize()`
+- Cart page shows error state with retry button
+- Local Hive cache used if available
+

+- **Repository**: `lib/features/cart/data/repositories/cart_repository_impl.dart`
+- **HomePage**: `lib/features/home/presentation/pages/home_page.dart`
+
+## Future Enhancements
+
+Potential improvements:
+- Add periodic background sync (every 5 minutes)
+- Implement optimistic updates for faster UI
+- Add cart merge logic when switching accounts
+- Implement cart expiry (clear after 30 days)
+- Add analytics tracking for cart events

+# Cart Feature Update Summary
+
+## Overview
+Updated the cart feature to match the new HTML design with selection checkboxes, sticky footer, and conversion quantity display.
+
+## Files Modified
+
+### 1. Cart State (`lib/features/cart/presentation/providers/cart_state.dart`)
+
+**Changes:**
+- Added `quantityConverted` (double) and `boxes` (int) fields to `CartItemData`
+- Updated `lineTotal` calculation to use `quantityConverted` instead of `quantity`
+- Added `selectedItems` map (productId -> isSelected) to `CartState`
+- Added getters:
+  - `selectedCount` - Number of selected items
+  - `isAllSelected` - Check if all items are selected
+  - `selectedTotal` - Total price of selected items only
+
+**Impact:**
+- Cart items now track both user-entered quantity and converted (rounded-up) quantity
+- Supports per-item selection for deletion and checkout
+
+---
+
+### 2. Cart Provider (`lib/features/cart/presentation/providers/cart_provider.dart`)
+
+**New Methods:**
+- `_calculateConversion(quantity)` - Simulates 8% markup for rounding up tiles
+  - Returns `(convertedQuantity, boxes)` tuple
+- `toggleSelection(productId)` - Toggle single item selection
+- `toggleSelectAll()` - Select/deselect all items
+- `deleteSelected()` - Remove all selected items from cart
+
+**Updated Methods:**
+- `addToCart()` - Auto-selects new items, calculates conversion
+- `removeFromCart()` - Also removes from selection map
+- `updateQuantity()` - Recalculates conversion on quantity change
+- `_recalculateTotal()` - Only includes selected items in total calculation
+
+**Key Logic:**
+```dart
+// Conversion calculation (simulated)
+final converted = (quantity * 1.008 * 100).ceilToDouble() / 100;
+final boxes = (quantity * 2.8).ceil();
+```
+
+---
+
+### 3. Cart Item Widget (`lib/features/cart/presentation/widgets/cart_item_widget.dart`)
+
+**New Features:**
+- Checkbox on left side (20x20px, 6px radius)
+- Checkbox aligned 34px from top to match HTML design
+- Converted quantity display below quantity controls:
+  ```
+  (Quy đổi: 10.08 m² = 28 viên)
+  ```
+
+**Layout:**
+```

+)
+```
+
+### Cart State
+```dart
+CartState(
+  items: [CartItemData(...)],
+  selectedItems: {
+    'product-1': true,
+    'product-2': false,
+    'product-3': true,
+  },
+  selectedWarehouse: 'Kho Hà Nội - Nguyễn Trãi',
+  memberTier: 'Diamond',
+  memberDiscountPercent: 15.0,
+  subtotal: 17107200.0,       // Only selected items
+  total: 14541120.0,          // After discount
+  ...
+)
+```
+
+---
+

+## Testing Notes
+
+### Manual Test Scenarios:
+
+1. **Selection**
+   - [ ] Add 3 items to cart
+   - [ ] Toggle individual checkboxes
+   - [ ] Use "Select All" button in AppBar
+   - [ ] Use "Chọn tất cả" in select all section
+   - [ ] Verify count: "Đã chọn: X/Y"
+
+2. **Deletion**
+   - [ ] Select 2 items
+   - [ ] Click delete button
+   - [ ] Confirm deletion
+   - [ ] Verify items removed and total updated
+
+3. **Conversion Display**
+   - [ ] Add item with quantity 10
+   - [ ] Verify conversion shows: "(Quy đổi: 10.08 m² = 28 viên)"
+   - [ ] Change quantity to 15
+   - [ ] Verify conversion updates
+
+4. **Checkout Flow**
+   - [ ] Select items
+   - [ ] Click "Tiến hành đặt hàng"
+   - [ ] Verify checkout page shows conversion details
+   - [ ] Check payment method options (2 radios)
+   - [ ] Verify Diamond discount shown
+
+5. **Empty States**
+   - [ ] Delete all items
+   - [ ] Verify empty cart message
+   - [ ] Select 0 items
+   - [ ] Verify checkout button disabled
+   - [ ] Verify delete button disabled
+
+---
+
+## Migration Notes
+
+### Breaking Changes:
+- `CartItemData` constructor now requires `quantityConverted` and `boxes`
+- Existing cart data will need migration
+- Any code reading cart items must handle new fields
+
+### Backward Compatibility:
+- Old cart items won't have conversion data
+- Consider adding migration in cart provider initialization
+- Default conversion: `quantityConverted = quantity * 1.01`, `boxes = 0`
+
+### TODO for Production:
+1. Replace mock conversion calculation with backend API
+2. Get conversion rate from product specifications (tile size)
+3. Persist selection state in Hive (optional)
+4. Add loading states for delete operation
+5. Implement undo for accidental deletions
+6. Add analytics for selection patterns
+
+---
+
+## Performance Considerations
+
+- Selection state stored in Map for O(1) lookups
+- Total recalculated on every selection change
+- Consider debouncing if performance issues arise
+- Sticky footer uses Stack/Positioned for smooth scroll
+
+---
+
+## Accessibility
+
+- All checkboxes have proper touch targets (22x22 minimum)
+- Delete button has tooltip
+- Disabled states have visual feedback (opacity)
+- Selection count announced for screen readers
+
+---
+
+## Next Steps
+
+1. Test on physical devices
+2. Verify conversion calculations with business team
+3. Update API integration for conversion data
+4. Add unit tests for selection logic
+5. Add widget tests for cart page
+6. Consider adding animation for item deletion

+Icon(Icons.add, size: 16)
+IconButton(
+  icon: Icon(Icons.delete_outline),
+  onPressed: () {},
+)
+```
+
+### After (FontAwesome)
+```dart
+FaIcon(FontAwesomeIcons.cartShopping, size: 24, color: Colors.blue)
+FaIcon(FontAwesomeIcons.plus, size: 16)
+IconButton(
+  icon: FaIcon(FontAwesomeIcons.trashCan),
+  onPressed: () {},
+)
+```
+
+## Size Guidelines
+
+FontAwesome icons tend to be slightly larger than Material icons at the same size. Recommended adjustments:
+
+| Material Size | FontAwesome Size | Notes |
+|---------------|------------------|-------|
+| 24 (default) | 20-22 | Standard icons |
+| 20 | 18 | Small icons |
+| 16 | 14-15 | Tiny icons |
+| 48 | 40-44 | Large icons |
+| 64 | 56-60 | Extra large |
+
+## Color Usage
+
+FontAwesome icons use the same color properties:
+```dart
+// Both work the same
+Icon(Icons.add, color: AppColors.primaryBlue)
+FaIcon(FontAwesomeIcons.plus, color: AppColors.primaryBlue)
+```
+
+## Common Issues & Solutions
+
+### Issue 1: Icon Size Mismatch
+**Problem**: FontAwesome icons appear larger than expected
+**Solution**: Reduce size by 2-4 pixels
+```dart
+// Before
+Icon(Icons.add, size: 24)
+
+// After
+FaIcon(FontAwesomeIcons.plus, size: 20)
+```
+
+### Issue 2: Icon Alignment
+**Problem**: Icons not centered properly
+**Solution**: Use `IconTheme` or wrap in `SizedBox`
+```dart
+SizedBox(
+  width: 24,
+  height: 24,
+  child: FaIcon(FontAwesomeIcons.plus, size: 18),
+)
+```
+
+### Issue 3: Icon Not Found
+**Problem**: Icon name doesn't match
+**Solution**: Check FontAwesome documentation or use search
+```dart
+// Use camelCase, not snake_case
+// ❌ FontAwesomeIcons.shopping_cart
+// ✅ FontAwesomeIcons.cartShopping
+```
+
+## Migration Checklist
+
+- [x] Add `font_awesome_flutter` to pubspec.yaml
+- [x] Run `flutter pub get`
+- [ ] Update all `Icons.*` to `FontAwesomeIcons.*`
+- [ ] Replace `Icon()` with `FaIcon()`

+# Review API Integration - Implementation Summary
+
+## Overview
+Successfully integrated the Review/Feedback API into the Flutter Worker app, replacing mock review data with real API calls from the Frappe/ERPNext backend.
+
+## Implementation Date
+November 17, 2024
+
+---
+
+## API Endpoints Integrated
+
+### 1. Get List Reviews
+```
+POST /api/method/building_material.building_material.api.item_feedback.get_list
+
+Request Body:
+{
+  "limit_page_length": 10,
+  "limit_start": 0,
+  "item_id": "GIB20 G04"
+}
+```
+
+### 2. Create/Update Review
+```
+POST /api/method/building_material.building_material.api.item_feedback.update
+
+Request Body:
+{
+  "item_id": "Gạch ốp Signature SIG.P-8806",
+  "rating": 0.5,  // 0-1 scale (0.5 = 2.5 stars out of 5)
+  "comment": "Good job 2",
+  "name": "ITEM-{item_id}-{user_email}"  // Optional for updates
+}
+```
+
+### 3. Delete Review
+```
+POST /api/method/building_material.building_material.api.item_feedback.delete
+
+Request Body:
+{
+  "name": "ITEM-{item_id}-{user_email}"
+}
+```
+
+---
+
+## Rating Scale Conversion
+
+**CRITICAL**: The API uses a 0-1 rating scale while the UI uses 1-5 stars.
+
+### Conversion Formulas
+- **API to UI**: `stars = (apiRating * 5).round()`
+- **UI to API**: `apiRating = stars / 5.0`
+
+### Examples
+| API Rating | Stars (Decimal) | Stars (Rounded) |
+|------------|-----------------|-----------------|
+| 0.2        | 1.0             | 1 star          |
+| 0.4        | 2.0             | 2 stars         |
+| 0.5        | 2.5             | 3 stars         |
+| 0.8        | 4.0             | 4 stars         |
+| 1.0        | 5.0             | 5 stars         |
+
+**Implementation**:
+- `Review.starsRating` getter: Returns rounded integer (0-5)
+- `Review.starsRatingDecimal` getter: Returns exact decimal (0-5)
+- `starsToApiRating()` helper: Converts UI stars to API rating
+- `apiRatingToStars()` helper: Converts API rating to UI stars

+
+## Domain Layer
+
+### Review Entity
+**File**: `/Users/ssg/project/worker/lib/features/reviews/domain/entities/review.dart`
+
+```dart
+class Review {
+  final String id;              // Review ID (format: ITEM-{item_id}-{user_email})
+  final String itemId;          // Product item code
+  final double rating;          // API rating (0-1 scale)
+  final String comment;         // Review text
+  final String? reviewerName;   // Reviewer name
+  final String? reviewerEmail;  // Reviewer email
+  final DateTime? reviewDate;   // Review date
+
+  // Convert API rating (0-1) to stars (0-5)
+  int get starsRating => (rating * 5).round();
+
+  // Get exact decimal rating (0-5)
+  double get starsRatingDecimal => rating * 5;
+}
+```
+
+### Repository Interface
+**File**: `/Users/ssg/project/worker/lib/features/reviews/domain/repositories/reviews_repository.dart`
+
+```dart
+abstract class ReviewsRepository {
+  Future<List<Review>> getProductReviews({
+    required String itemId,
+    int limitPageLength = 10,
+    int limitStart = 0,
+  });
+
+  Future<void> submitReview({
+    required String itemId,
+    required double rating,
+    required String comment,
+    String? name,
+  });
+
+  Future<void> deleteReview({required String name});
+}
+```
+
+### Use Cases
+1. **GetProductReviews**: Fetches reviews with pagination
+2. **SubmitReview**: Creates or updates a review (validates rating 0-1, comment 20-1000 chars)
+3. **DeleteReview**: Deletes a review by ID
+
+---
+
+## Data Layer

+- Sorts reviews by date (newest first)
+- Delegates to remote data source
+
+---
+
+## Presentation Layer
+
+### Riverpod Providers
+**File**: `/Users/ssg/project/worker/lib/features/reviews/presentation/providers/reviews_provider.dart`
+
+**Data Layer Providers**:
+- `reviewsRemoteDataSourceProvider`: Remote data source instance
+- `reviewsRepositoryProvider`: Repository instance
+
+**Use Case Providers**:
+- `getProductReviewsProvider`: Get reviews use case
+- `submitReviewProvider`: Submit review use case
+- `deleteReviewProvider`: Delete review use case
+
+**State Providers**:
+```dart
+// Fetch reviews for a product
+final reviewsAsync = ref.watch(productReviewsProvider(itemId));
+
+// Calculate average rating
+final avgRating = ref.watch(productAverageRatingProvider(itemId));
+
+// Get review count
+final count = ref.watch(productReviewCountProvider(itemId));
+
+// Check if user can submit review
+final canSubmit = ref.watch(canSubmitReviewProvider(itemId));
+```
+
+**Helper Functions**:
+```dart
+// Convert UI stars to API rating
+double apiRating = starsToApiRating(5); // 1.0
+
+// Convert API rating to UI stars
+int stars = apiRatingToStars(0.8); // 4
+```
+
+---
+
+## UI Updates
+
+### 1. ProductTabsSection Widget
+**File**: `/Users/ssg/project/worker/lib/features/products/presentation/widgets/product_detail/product_tabs_section.dart`
+
+**Changes**:
+- Changed `_ReviewsTab` from `StatelessWidget` to `ConsumerWidget`
+- Replaced mock reviews with `productReviewsProvider`
+- Added real-time average rating calculation
+- Implemented loading, error, and empty states
+- Updated `_ReviewItem` to use `Review` entity instead of `Map`
+- Added date formatting function (`_formatDate`)
+
+**States**:
+1. **Loading**: Shows CustomLoadingIndicator
+2. **Error**: Shows error icon and message
+3. **Empty**: Shows "Chưa có đánh giá nào" with call-to-action
+4. **Data**: Shows rating overview and review list
+
+**Rating Overview**:
+- Dynamic average rating display (0-5 scale)
+- Star rendering with full/half/empty stars
+- Review count from actual data
+
+**Review Cards**:
+- Reviewer name (with fallback to "Người dùng")
+- Relative date formatting (e.g., "2 ngày trước", "1 tuần trước")
+- Star rating (converted from 0-1 to 5 stars)
+- Comment text
+
+### 2. WriteReviewPage
+**File**: `/Users/ssg/project/worker/lib/features/products/presentation/pages/write_review_page.dart`

+
+---
+
+## API Constants Updated
+
+**File**: `/Users/ssg/project/worker/lib/core/constants/api_constants.dart`
+
+Added three new constants:
+```dart
+static const String frappeGetReviews =
+  '/building_material.building_material.api.item_feedback.get_list';
+
+static const String frappeUpdateReview =
+  '/building_material.building_material.api.item_feedback.update';
+
+static const String frappeDeleteReview =
+  '/building_material.building_material.api.item_feedback.delete';
+```
+
+---
+
+## Error Handling
+
+### Network Errors
+- **NoInternetException**: "Không có kết nối internet"
+- **TimeoutException**: "Kết nối quá lâu. Vui lòng thử lại."
+- **ServerException**: "Lỗi máy chủ. Vui lòng thử lại sau."
+
+### HTTP Status Codes
+- **400**: BadRequestException - "Dữ liệu không hợp lệ"
+- **401**: UnauthorizedException - "Phiên đăng nhập hết hạn"
+- **403**: ForbiddenException - "Không có quyền truy cập"
+- **404**: NotFoundException - "Không tìm thấy đánh giá"
+- **409**: ConflictException - "Đánh giá đã tồn tại"
+- **429**: RateLimitException - "Quá nhiều yêu cầu"
+- **500+**: ServerException - Custom message from API
+
+### Validation Errors
+- Rating must be 0-1 (API scale)
+- Comment must be 20-1000 characters
+- Comment cannot be empty
+
+---
+
+## Authentication Requirements
+
+All review API endpoints require:
+1. **Cookie**: `sid={session_id}` (from auth flow)
+2. **Header**: `X-Frappe-Csrf-Token: {csrf_token}` (from auth flow)
+
+These are handled automatically by the `AuthInterceptor` in the DioClient configuration.
+
+---
+
+## Review ID Format
+
+The review ID (name field) follows this pattern:
+```
+ITEM-{item_id}-{user_email}
+```
+
+**Examples**:
+- `ITEM-GIB20 G04-john.doe@example.com`
+- `ITEM-Gạch ốp Signature SIG.P-8806-user@company.com`
+
+This ID is used for:
+- Identifying reviews in the system
+- Updating existing reviews (pass as `name` parameter)
+- Deleting reviews
+
+---
+
+## Pagination Support
+
+The `getProductReviews` endpoint supports pagination:
+
+```dart
+// Fetch first 10 reviews
+final reviews = await repository.getProductReviews(
+  itemId: 'GIB20 G04',
+  limitPageLength: 10,
+  limitStart: 0,
+);
+
+// Fetch next 10 reviews
+final moreReviews = await repository.getProductReviews(
+  itemId: 'GIB20 G04',
+  limitPageLength: 10,
+  limitStart: 10,
+);
+```
+
+**Current Implementation**: Fetches 50 reviews at once (can be extended with infinite scroll)
+
+---
+
+## Testing Checklist

+
+---
+
+## Known Issues and Limitations
+
+### 1. Build Runner
+**Issue**: Cannot run `dart run build_runner build` due to Dart SDK version mismatch
+- Required: Dart 3.10.0
+- Available: Dart 3.9.2
+
+**Workaround**: Manually created `reviews_provider.g.dart` file
+
+**Solution**: Upgrade Dart SDK to 3.10.0 and regenerate
+
+### 2. API Response Format
+**Issue**: Actual API response structure not fully documented
+
+**Assumption**: Based on common Frappe patterns:
+```json
+{
+  "message": [
+    {
+      "name": "...",
+      "item_id": "...",
+      "rating": 0.5,
+      "comment": "...",
+      "owner": "...",
+      "creation": "..."
+    }
+  ]
+}
+```
+
+**Recommendation**: Test with actual API and adjust `ReviewModel.fromJson()` if needed
+
+### 3. One Review Per User
+**Current**: Users can submit multiple reviews for the same product
+
+**Future Enhancement**:
+- Check if user already reviewed product
+- Update `canSubmitReviewProvider` to enforce one-review-per-user
+- Show "Edit Review" instead of "Write Review" for existing reviews
+
+### 4. Review Deletion
+**Current**: Delete functionality implemented but not exposed in UI
+
+**Future Enhancement**:
+- Add "Delete" button for user's own reviews
+- Require confirmation dialog
+- Refresh list after deletion
+
+---
+
+## Next Steps
+
+### Immediate
+1. **Test with Real API**: Verify actual response format and adjust model if needed
+2. **Upgrade Dart SDK**: To 3.10.0 for proper code generation
+3. **Run Build Runner**: Regenerate provider code automatically
+
+### Short-term
+1. **Add Review Editing**: Allow users to edit their own reviews
+2. **Add Review Deletion UI**: Show delete button for user's reviews
+3. **Implement Pagination**: Add "Load More" button for reviews
+4. **Add Helpful Button**: Allow users to mark reviews as helpful
+5. **Add Review Images**: Support photo uploads in reviews
+
+### Long-term
+1. **Review Moderation**: Admin panel for reviewing flagged reviews
+2. **Verified Purchase Badge**: Show badge for reviews from verified purchases
+3. **Review Sorting**: Sort by date, rating, helpful votes
+4. **Review Filtering**: Filter by star rating
+5. **Review Analytics**: Show rating distribution graph
+

+## Code Examples
+
+### Fetching Reviews in a Widget
+```dart
+@override
+Widget build(BuildContext context, WidgetRef ref) {
+  final reviewsAsync = ref.watch(productReviewsProvider('PRODUCT_ID'));
+
+  return reviewsAsync.when(
+    data: (reviews) {
+      if (reviews.isEmpty) {
+        return Text('No reviews yet');
+      }
+      return ListView.builder(
+        itemCount: reviews.length,
+        itemBuilder: (context, index) {
+          final review = reviews[index];
+          return ListTile(
+            title: Text(review.reviewerName ?? 'Anonymous'),
+            subtitle: Text(review.comment),
+            leading: Row(
+              mainAxisSize: MainAxisSize.min,
+              children: List.generate(
+                5,
+                (i) => Icon(
+                  i < review.starsRating
+                      ? Icons.star
+                      : Icons.star_border,
+                ),
+              ),
+            ),
+          );
+        },
+      );
+    },
+    loading: () => const CustomLoadingIndicator(),
+    error: (error, stack) => Text('Error: $error'),
+  );
+}
+```
+
+### Submitting a Review
+```dart
+Future<void> submitReview(WidgetRef ref, String productId, int stars, String comment) async {
+  try {
+    final submitUseCase = ref.read(submitReviewProvider);
+
+    // Convert stars (1-5) to API rating (0-1)
+    final apiRating = stars / 5.0;
+
+    await submitUseCase(
+      itemId: productId,
+      rating: apiRating,
+      comment: comment,
+    );
+
+    // Refresh reviews list
+    ref.invalidate(productReviewsProvider(productId));
+
+    // Show success message
+    ScaffoldMessenger.of(context).showSnackBar(
+      SnackBar(content: Text('Review submitted successfully!')),
+    );
+  } catch (e) {
+    // Show error message
+    ScaffoldMessenger.of(context).showSnackBar(
+      SnackBar(content: Text('Error: $e')),
+    );
+  }
+}
+```
+
+### Getting Average Rating

+Widget build(BuildContext context, WidgetRef ref) {
+  final avgRatingAsync = ref.watch(productAverageRatingProvider('PRODUCT_ID'));
+
+  return avgRatingAsync.when(
+    data: (avgRating) => Text(
+      'Average: ${avgRating.toStringAsFixed(1)} stars',
+    ),
+    loading: () => Text('Loading...'),

+

+
+## State Management Lifecycle
+
+```
+1. Initial State (Loading)
+   ├─► productReviewsProvider returns AsyncValue.loading()
+   └─► UI shows CustomLoadingIndicator
+
+2. Loading State → Data State
+   ├─► API call succeeds
+   ├─► Provider returns AsyncValue.data(List<Review>)
+   └─► UI shows review list
+
+3. Data State → Refresh State (after submit)
+   ├─► User submits new review
+   ├─► ref.invalidate(productReviewsProvider)
+   ├─► Provider state reset to loading
+   ├─► API call re-executes
+   └─► UI updates with new data
+
+4. Error State
+   ├─► API call fails
+   ├─► Provider returns AsyncValue.error(exception)
+   └─► UI shows error message
+
+5. Empty State (special case of Data State)
+   ├─► API returns empty list
+   ├─► Provider returns AsyncValue.data([])
+   └─► UI shows "No reviews yet" message
+```
+
+---
+
+## Caching Strategy
+
+```
+Provider State Cache (Riverpod)
+         │
+         ├─► Auto-disposed when widget unmounted
+         │   (productReviewsProvider uses AutoDispose)
+         │
+         ├─► Cache invalidated on:
+         │   - User submits review
+         │   - User deletes review
+         │   - Manual ref.invalidate() call
+         │
+         └─► Cache refresh:
+             - Pull-to-refresh gesture (future enhancement)
+             - App resume from background (future enhancement)
+             - Time-based expiry (future enhancement)
+
+HTTP Cache (Dio CacheInterceptor)
+         │
+         ├─► Reviews NOT cached (POST requests)
+         │   (only GET requests cached by default)
+         │
+         └─► Future: Implement custom cache policy
+             - Cache reviews for 5 minutes
+             - Invalidate on write operations
+```
+
+---
+
+## Testing Strategy
+
+```
+Unit Tests
+├─► Domain Layer
+│   ├─► Use cases
+│   │   ├─► GetProductReviews
+│   │   ├─► SubmitReview (validates rating & comment)
+│   │   └─► DeleteReview
+│   └─► Entities
+│       └─► Review (starsRating computation)
+│
+├─► Data Layer
+│   ├─► Models (fromJson, toJson, toEntity)
+│   ├─► Remote Data Source (API calls, error handling)
+│   └─► Repository (model-to-entity conversion, sorting)
+│
+└─► Presentation Layer
+    └─► Providers (state transformations)
+
+Widget Tests
+├─► _ReviewsTab
+│   ├─► Loading state
+│   ├─► Empty state
+│   ├─► Data state
+│   └─► Error state
+│
+├─► _ReviewItem
+│   ├─► Displays correct data
+│   ├─► Date formatting
+│   └─► Star rendering
+│
+└─► WriteReviewPage
+    ├─► Form validation
+    ├─► Submit button states
+    └─► Error messages
+
+Integration Tests
+└─► End-to-end flow
+    ├─► Fetch reviews
+    ├─► Submit review
+    ├─► Verify refresh
+    └─► Error scenarios
+```
+
+This architecture follows:
+- ✅ Clean Architecture principles
+- ✅ SOLID principles
+- ✅ Dependency Inversion (interfaces in domain layer)
+- ✅ Single Responsibility (each class has one job)
+- ✅ Separation of Concerns (UI, business logic, data separate)
+- ✅ Testability (all layers mockable)

+# Reviews API - Quick Reference Guide
+
+## Rating Scale Conversion
+
+### Convert UI Stars to API Rating
+```dart
+// UI: 5 stars → API: 1.0
+final apiRating = stars / 5.0;
+```
+
+### Convert API Rating to UI Stars
+```dart
+// API: 0.8 → UI: 4 stars
+final stars = (rating * 5).round();
+```
+
+### Helper Functions (in reviews_provider.dart)
+```dart
+double apiRating = starsToApiRating(5);  // Returns 1.0
+int stars = apiRatingToStars(0.8);       // Returns 4
+```
+
+---
+
+## Provider Usage
+
+### Get Reviews for Product
+```dart
+final reviewsAsync = ref.watch(productReviewsProvider(itemId));
+
+reviewsAsync.when(
+  data: (reviews) => /* show reviews */,
+  loading: () => const CustomLoadingIndicator(),
+  error: (error, stack) => /* show error */,
+);
+```
+
+### Get Average Rating
+```dart
+final avgRatingAsync = ref.watch(productAverageRatingProvider(itemId));
+```
+
+### Get Review Count
+```dart
+final countAsync = ref.watch(productReviewCountProvider(itemId));
+```
+
+### Submit Review
+```dart
+try {
+  final submitUseCase = ref.read(submitReviewProvider);
+
+  await submitUseCase(
+    itemId: productId,
+    rating: stars / 5.0,  // Convert stars to 0-1
+    comment: comment,
+  );
+
+  // Refresh reviews
+  ref.invalidate(productReviewsProvider(productId));
+} catch (e) {
+  // Handle error
+}
+```
+
+### Delete Review
+```dart
+try {
+  final deleteUseCase = ref.read(deleteReviewProvider);
+
+  await deleteUseCase(name: reviewId);
+
+  // Refresh reviews
+  ref.invalidate(productReviewsProvider(productId));
+} catch (e) {
+  // Handle error
+}
+```
+
+---
+
+## API Endpoints
+
+### Get Reviews

+  // Invalid data: e.message
+} on NotFoundException {
+  // Review not found
+} on ServerException {
+  // Server error (5xx)
+} catch (e) {
+  // Unknown error
+}
+```
+
+### Status Codes
+- **400**: Bad Request - Invalid data
+- **401**: Unauthorized - Session expired
+- **403**: Forbidden - No permission
+- **404**: Not Found - Review doesn't exist
+- **409**: Conflict - Review already exists
+- **429**: Too Many Requests - Rate limited
+- **500+**: Server Error
+
+---
+
+## Validation Rules
+
+### Rating
+- Must be 0-1 for API
+- Must be 1-5 for UI
+- Cannot be empty
+
+### Comment
+- Minimum: 20 characters
+- Maximum: 1000 characters
+- Cannot be empty or whitespace only
+
+---
+
+## Date Formatting
+
+```dart
+String _formatDate(DateTime date) {
+  final now = DateTime.now();
+  final diff = now.difference(date);
+
+  if (diff.inDays == 0) return 'Hôm nay';
+  if (diff.inDays == 1) return 'Hôm qua';
+  if (diff.inDays < 7) return '${diff.inDays} ngày trước';
+  if (diff.inDays < 30) return '${(diff.inDays / 7).floor()} tuần trước';
+  if (diff.inDays < 365) return '${(diff.inDays / 30).floor()} tháng trước';
+  return '${(diff.inDays / 365).floor()} năm trước';
+}
+```
+
+---
+
+## Review ID Format
+
+```
+ITEM-{item_id}-{user_email}
+```
+
+**Examples**:
+- `ITEM-GIB20 G04-john@example.com`
+- `ITEM-Product123-user@company.com`
+
+---
+
+## Testing Checklist
+
+- [ ] Reviews load correctly
+- [ ] Rating conversion works (0-1 ↔ 1-5)
+- [ ] Submit review refreshes list
+- [ ] Average rating calculates correctly
+- [ ] Empty state shows when no reviews
+- [ ] Loading state shows during API calls
+- [ ] Error messages display correctly
+- [ ] Date formatting works
+- [ ] Star ratings display correctly
+- [ ] Form validation works
+
+---
+
+## Common Issues
+
+### Issue: Reviews not loading
+**Solution**: Check auth tokens (sid, csrf_token) are set
+
+### Issue: Rating conversion wrong
+**Solution**: Always use `stars / 5.0` for API, `(rating * 5).round()` for UI
+
+### Issue: Reviews not refreshing after submit
+**Solution**: Use `ref.invalidate(productReviewsProvider(itemId))`
+
+### Issue: Provider not found error
+**Solution**: Run `dart run build_runner build` to generate .g.dart files

+# Favorites API Integration - Implementation Summary
+
+## Overview
+Successfully integrated the Frappe ERPNext favorites/wishlist API with the Worker app using an **online-first approach**. The implementation follows clean architecture principles with proper separation of concerns.
+
+## API Endpoints (from docs/favorite.sh)
+
+### 1. Get Favorites List
+```
+POST /api/method/building_material.building_material.api.item_wishlist.get_list
+Body: { "limit_start": 0, "limit_page_length": 0 }
+```
+
+### 2. Add to Favorites
+```
+POST /api/method/building_material.building_material.api.item_wishlist.add_to_wishlist
+Body: { "item_id": "GIB20 G04" }
+```
+
+### 3. Remove from Favorites
+```
+POST /api/method/building_material.building_material.api.item_wishlist.remove_from_wishlist
+Body: { "item_id": "GIB20 G04" }
+```
+
+## Implementation Architecture
+
+### Files Created/Modified
+
+#### 1. API Constants
+**File**: `lib/core/constants/api_constants.dart`
+- Added favorites endpoints:
+  - `getFavorites`
+  - `addToFavorites`
+  - `removeFromFavorites`
+
+#### 2. Remote DataSource
+**File**: `lib/features/favorites/data/datasources/favorites_remote_datasource.dart`
+- `getFavorites()` - Fetch all favorites from API
+- `addToFavorites(itemId)` - Add item to wishlist
+- `removeFromFavorites(itemId)` - Remove item from wishlist
+- Proper error handling with custom exceptions
+- Maps API response to `FavoriteModel`
+
+#### 3. Domain Repository Interface
+**File**: `lib/features/favorites/domain/repositories/favorites_repository.dart`
+- Defines contract for favorites operations
+- Documents online-first approach
+- Methods: `getFavorites`, `addFavorite`, `removeFavorite`, `isFavorite`, `getFavoriteCount`, `clearFavorites`, `syncFavorites`
+
+#### 4. Repository Implementation
+**File**: `lib/features/favorites/data/repositories/favorites_repository_impl.dart`
+- **Online-first strategy**:
+  1. Try API call when connected
+  2. Update local cache with API response
+  3. Fall back to local cache on network errors
+  4. Queue changes for sync when offline
+
+**Key Methods**:
+- `getFavorites()` - Fetches from API, caches locally, falls back to cache
+- `addFavorite()` - Adds via API, caches locally, queues offline changes
+- `removeFavorite()` - Removes via API, updates cache, queues offline changes
+- `syncFavorites()` - Syncs pending changes when connection restored
+
+#### 5. Provider Updates
+**File**: `lib/features/favorites/presentation/providers/favorites_provider.dart`
+
+**New Providers**:
+- `favoritesRemoteDataSourceProvider` - Remote API datasource
+- `favoritesRepositoryProvider` - Repository with online-first approach
+
+**Updated Favorites Provider**:
+- Now uses repository instead of direct local datasource
+- Supports online-first operations
+- Auto-syncs with API on refresh
+- Maintains backward compatibility with existing UI
+
+## Online-First Flow
+
+### Adding a Favorite
+```
+User taps favorite icon
+    ↓
+Check network connectivity
+    ↓
+If ONLINE:
+  → Call API to add favorite
+  → Cache result locally
+  → Update UI state
+    ↓
+If OFFLINE:
+  → Add to local cache immediately
+  → Queue for sync (TODO)
+  → Update UI state
+  → Sync when connection restored
+```
+
+### Loading Favorites
+```
+App loads favorites page
+    ↓
+Check network connectivity
+    ↓
+If ONLINE:
+  → Fetch from API
+  → Update local cache
+  → Display results
+    ↓
+If API FAILS:
+  → Fall back to local cache
+  → Display cached data
+    ↓
+If OFFLINE:
+  → Load from local cache
+  → Display cached data
+```
+
+### Removing a Favorite
+```
+User removes favorite
+    ↓
+Check network connectivity
+    ↓
+If ONLINE:
+  → Call API to remove
+  → Update local cache
+  → Update UI state
+    ↓
+If OFFLINE:
+  → Remove from cache immediately
+  → Queue for sync (TODO)
+  → Update UI state
+  → Sync when connection restored
+```
+
+## Error Handling
+
+### Network Errors
+- `NetworkException` - Connection issues, timeouts
+- Falls back to local cache
+- Shows cached data to user
+
+### Server Errors
+- `ServerException` - 500 errors, invalid responses
+- Falls back to local cache
+- Logs error for debugging
+
+### Authentication Errors
+- `UnauthorizedException` - 401/403 errors
+- Prompts user to re-login
+- Does not fall back to cache
+
+## Offline Queue (Future Enhancement)
+
+### TODO: Implement Sync Queue
+Currently, offline changes are persisted locally but not automatically synced when connection is restored.
+
+**Future Implementation**:
+1. Create offline queue datasource
+2. Queue failed API calls with payload
+3. Process queue on connection restore
+4. Handle conflicts (item deleted on server, etc.)
+5. Show sync status to user
+
+**Files to Create**:
+- `lib/core/sync/offline_queue_datasource.dart`
+- `lib/core/sync/sync_manager.dart`
+
+## Testing
+
+### Unit Tests (TODO)
+- `test/features/favorites/data/datasources/favorites_remote_datasource_test.dart`
+- `test/features/favorites/data/repositories/favorites_repository_impl_test.dart`
+- `test/features/favorites/presentation/providers/favorites_provider_test.dart`
+
+### Integration Tests (TODO)
+- Test online-first flow
+- Test offline fallback
+- Test sync after reconnection
+
+## Usage Example
+
+### In UI Code
+```dart
+// Add favorite
+ref.read(favoritesProvider.notifier).addFavorite(productId);
+
+// Remove favorite
+ref.read(favoritesProvider.notifier).removeFavorite(productId);
+
+// Check if favorited
+final isFav = ref.watch(isFavoriteProvider(productId));
+
+// Refresh from API
+ref.read(favoritesProvider.notifier).refresh();
+```
+
+## Benefits of This Implementation
+
+1. **Online-First** - Always uses fresh data when available
+2. **Offline Support** - Works without network, syncs later
+3. **Fast UI** - Immediate feedback from local cache
+4. **Error Resilient** - Graceful fallback on failures
+5. **Clean Architecture** - Easy to test and maintain
+6. **Type Safe** - Full Dart/Flutter type checking
+
+## API Response Format
+
+### Get Favorites Response
+```json
+{
+  "message": [
+    {
+      "name": "GIB20 G04",
+      "item_code": "GIB20 G04",
+      "item_name": "Gibellina GIB20 G04",
+      "item_group_name": "OUTDOOR [20mm]",
+      "custom_link_360": "https://...",
+      "thumbnail": "https://...",
+      "price": 0,
+      "currency": "",
+      "conversion_of_sm": 5.5556
+    }
+  ]
+}
+```
+
+### Add/Remove Response
+Standard Frappe response with status code 200 on success.
+
+## Configuration Required
+
+### Authentication
+The API requires:
+- `Cookie` header with `sid` (session ID)
+- `X-Frappe-Csrf-Token` header
+
+These are automatically added by the `AuthInterceptor` in `lib/core/network/api_interceptor.dart`.
+
+### Base URL
+Set in `lib/core/constants/api_constants.dart`:
+```dart
+static const String baseUrl = 'https://land.dbiz.com';
+```
+
+## Next Steps
+
+1. **Test with real API** - Verify endpoints with actual backend
+2. **Implement sync queue** - Handle offline changes properly
+3. **Add error UI feedback** - Show sync status, errors to user
+4. **Write unit tests** - Test all datasources and repository
+5. **Add analytics** - Track favorite actions for insights
+6. **Optimize caching** - Fine-tune cache expiration strategy
+
+## Notes
+
+- Current implementation uses hardcoded `userId = 'user_001'` (line 32 in favorites_provider.dart)
+- TODO: Integrate with actual auth provider when available
+- Offline queue sync is not yet implemented - changes are cached locally but not automatically synced
+- All API calls use POST method as per Frappe ERPNext convention
+
+---
+
+**Implementation Date**: December 2024
+**Status**: ✅ Complete - Ready for Testing
+**Breaking Changes**: None - Backward compatible with existing UI

+# Favorites Page - Loading State Fix
+
+## Problem
+Users were seeing the empty state ("Chưa có sản phẩm yêu thích") flash briefly before the actual favorites data loaded, even when they had favorites. This created a poor user experience.
+
+## Root Cause
+The `favoriteProductsProvider` is an async provider that:
+1. Loads favorites from API/cache
+2. Fetches all products
+3. Filters to get favorite products
+
+During this process, the provider goes through these states:
+- **Loading** → Returns empty list [] → Shows loading skeleton
+- **Data** → If products.isEmpty → Shows empty state ❌ **FLASH**
+- **Data** → Returns actual products → Shows grid
+
+The flash happened because when the provider rebuilt, it momentarily returned an empty list before the actual data arrived.
+
+## Solution
+
+### 1. Added `ref.keepAlive()` to Providers
+```dart
+@riverpod
+class Favorites extends _$Favorites {
+  @override
+  Future<Set<String>> build() async {
+    ref.keepAlive(); // ← Prevents provider disposal
+    // ... rest of code
+  }
+}
+
+@riverpod
+Future<List<Product>> favoriteProducts(Ref ref) async {
+  ref.keepAlive(); // ← Keeps previous data in memory
+  // ... rest of code
+}
+```
+
+**Benefits**:
+- Prevents state from being disposed when widget rebuilds
+- Keeps previous data available via `favoriteProductsAsync.valueOrNull`
+- Reduces unnecessary API calls
+
+### 2. Smart Loading State Logic
+
+```dart
+loading: () {
+  // 1. Check for previous data first
+  final previousValue = favoriteProductsAsync.valueOrNull;
+
+  // 2. If we have previous data, show it while loading
+  if (previousValue != null && previousValue.isNotEmpty) {
+    return Stack([
+      _FavoritesGrid(products: previousValue), // Show old data
+      LoadingIndicator(), // Small loading badge on top
+    ]);
+  }
+
+  // 3. Use favoriteCount as a hint
+  if (favoriteCount > 0) {
+    return LoadingState(); // Show skeleton
+  }
+
+  // 4. No data, show skeleton (not empty state)
+  return LoadingState();
+}
+```
+
+### 3. Data State - Only Show Empty When Actually Empty
+
+```dart
+data: (products) {
+  // Only show empty state when data is actually empty
+  if (products.isEmpty) {
+    return const _EmptyState();
+  }
+
+  return RefreshIndicator(
+    child: _FavoritesGrid(products: products),
+  );
+}
+```
+
+## User Experience Flow
+
+### Before Fix ❌
+```
+User opens favorites page
+  ↓
+Loading skeleton shows (0.1s)
+  ↓
+Empty state flashes (0.2s) ⚡ BAD UX
+  ↓
+Favorites grid appears
+```
+
+### After Fix ✅
+```
+User opens favorites page
+  ↓
+Loading skeleton shows (0.3s)
+  ↓
+Favorites grid appears smoothly
+```
+
+**OR** if returning to page:
+```
+User opens favorites page (2nd time)
+  ↓
+Previous favorites show immediately
+  ↓
+Small "Đang tải..." badge appears at top
+  ↓
+Updated favorites appear (if changed)
+```
+
+## Additional Benefits
+
+### 1. Better Offline Support
+- When offline, previous data stays visible
+- Shows error banner on top instead of hiding content
+- User can still browse cached favorites
+
+### 2. Faster Perceived Performance
+- Instant display of previous data
+- Users don't see empty states during reloads
+- Smoother transitions
+
+### 3. Error Handling
+```dart
+error: (error, stackTrace) {
+  final previousValue = favoriteProductsAsync.valueOrNull;
+
+  // Show previous data with error message
+  if (previousValue != null && previousValue.isNotEmpty) {
+    return Stack([
+      _FavoritesGrid(products: previousValue),
+      ErrorBanner(onRetry: ...),
+    ]);
+  }
+
+  // No previous data, show full error state
+  return _ErrorState();
+}
+```
+
+## Files Modified
+
+1. **lib/features/favorites/presentation/providers/favorites_provider.dart**
+   - Added `ref.keepAlive()` to `Favorites` class (line 81)
+   - Added `ref.keepAlive()` to `favoriteProducts` provider (line 271)
+
+2. **lib/features/favorites/presentation/pages/favorites_page.dart**
+   - Enhanced loading state logic (lines 138-193)
+   - Added previous value checking
+   - Added favoriteCount hint logic
+
+## Testing Checklist
+
+- [x] No empty state flash on first load
+- [x] Smooth loading with skeleton
+- [x] Previous data shown on subsequent visits
+- [x] Loading indicator overlay when refreshing
+- [ ] Test with slow network (3G)
+- [ ] Test with offline mode
+- [ ] Test with errors during load
+
+## Performance Impact
+
+✅ **Positive**:
+- Reduced state rebuilds
+- Better memory management with keepAlive
+- Fewer API calls on navigation
+
+⚠️ **Watch**:
+- Memory usage (keepAlive keeps data in memory)
+- Can manually dispose with `ref.invalidate()` if needed
+
+## Future Improvements
+
+1. **Add shimmer duration control**
+   - Minimum shimmer display time to prevent flash
+   - Smooth fade transition from skeleton to content
+
+2. **Progressive loading**
+   - Show cached data first
+   - Overlay with "Updating..." badge
+   - Fade in updated items
+
+3. **Prefetch on app launch**
+   - Load favorites in background
+   - Data ready before user navigates to page
+
+---
+
+**Status**: ✅ Implemented
+**Impact**: High - Significantly improves perceived performance
+**Breaking Changes**: None

+# Order Model API Integration Update
+
+## Summary
+Updated OrderModel and orders_provider to match the simplified API response structure from the ERPNext/Frappe backend.
+
+## API Response Structure
+```json
+{
+    "message": [
+        {
+            "name": "SAL-ORD-2025-00107",
+            "transaction_date": "2025-11-24",
+            "delivery_date": "2025-11-24",
+            "address": "123 add dad",
+            "grand_total": 3355443.2,
+            "status": "Chờ phê duyệt",
+            "status_color": "Warning"
+        }
+    ]
+}
+```
+
+## Changes Made
+
+### 1. OrderModel (`lib/features/orders/data/models/order_model.dart`)
+**New Fields Added:**
+- `statusColor` (HiveField 18): Stores API status color (Warning, Success, Danger, etc.)
+- `transactionDate` (HiveField 19): Transaction date from API
+- `addressString` (HiveField 20): Simple string address from API
+
+**Updated Methods:**
+- `fromJson()`: Made fields more nullable, added new field mappings
+- `toJson()`: Added new fields to output
+- Constructor: Added new optional parameters
+
+### 2. Orders Provider (`lib/features/orders/presentation/providers/orders_provider.dart`)
+**API Field Mapping:**
+```dart
+{
+  'order_id': json['name'],
+  'order_number': json['name'],
+  'status': _mapStatusFromApi(json['status']),
+  'total_amount': json['grand_total'],
+  'final_amount': json['grand_total'],
+  'expected_delivery_date': json['delivery_date'],
+  'transaction_date': json['transaction_date'],
+  'address_string': json['address'],
+  'status_color': json['status_color'],
+  'created_at': json['transaction_date'],
+}
+```
+
+**Status Mapping:**
+- "Chờ phê duyệt" / "Pending approval" → `pending`
+- "Đang xử lý" / "Processing" → `processing`
+- "Đang giao" / "Shipped" → `shipped`
+- "Hoàn thành" / "Completed" → `completed`
+- "Đã hủy" / "Cancelled" / "Rejected" → `cancelled`
+
+### 3. Order Card Widget (`lib/features/orders/presentation/widgets/order_card.dart`)
+**Display Updates:**
+- Uses `transactionDate` if available, falls back to `createdAt`
+- Uses `addressString` directly from API instead of parsing JSON
+
+## Benefits
+1. **Simpler mapping**: Direct field mapping without complex transformations
+2. **API consistency**: Matches actual backend response structure
+3. **Better performance**: No need to parse JSON addresses for list view
+4. **Status colors**: API-provided colors ensure UI consistency with backend
+
+## API Endpoint
+```
+POST /api/method/building_material.building_material.api.sales_order.get_list
+Body: { "limit_start": 0, "limit_page_length": 0 }
+```
+
+## Testing Notes
+- Ensure API returns all expected fields
+- Verify Vietnamese status strings are correctly mapped
+- Check that dates are in ISO format (YYYY-MM-DD)
+- Confirm status_color values match StatusColor enum (Warning, Success, Danger, Info, Secondary)
