 ### Hive Best Practices
 **IMPORTANT: Box Type Management**
-When working with Hive boxes, always use `Box<dynamic>` in data sources and apply `.whereType<T>()` for type-safe queries:
-
-```dart
-// ✅ CORRECT - Use Box<dynamic> with type filtering
-Box<dynamic> get _box {
-  return Hive.box<dynamic>(HiveBoxNames.favoriteBox);
-}
-
-Future<List<FavoriteModel>> getAllFavorites(String userId) async {
-  try {
-    final favorites = _box.values
-        .whereType<FavoriteModel>()  // Type-safe filtering
-        .where((fav) => fav.userId == userId)
-        .toList();
-    return favorites;
-  } catch (e) {
-    debugPrint('[DataSource] Error: $e');
-    rethrow;
-  }
-}
-
-// ❌ INCORRECT - Will cause HiveError
-Box<FavoriteModel> get _box {
-  return Hive.box<FavoriteModel>(HiveBoxNames.favoriteBox);
-}
-```
+When working with Hive boxes, always use `Box<dynamic>` in data sources and apply `.whereType<T>()` for type-safe queries.
 
 **Reason**: Hive boxes are opened as `Box<dynamic>` in the central HiveService. Re-opening with a specific type causes `HiveError: The box is already open and of type Box<dynamic>`.

+**Problem Solved**: `HiveError: The box "favorite_box" is already open and of type Box<dynamic>`
 
 **Solution Applied**:
 - All data sources now use `Box<dynamic>` getters
 - Type-safe queries via `.whereType<T>()`
 - Applied to `favorites_local_datasource.dart`
 
-**Pattern**:
-```dart
-Box<dynamic> get _box => Hive.box<dynamic>(boxName);
-
-Future<List<FavoriteModel>> getAllFavorites() async {
-  return _box.values
-    .whereType<FavoriteModel>()  // Type-safe!

+
+## Best Practices
+
+### Hive Box Type Management
+
+**✅ CORRECT - Use Box<dynamic> with type filtering**
+```dart
+Box<dynamic> get _box {
+  return Hive.box<dynamic>(HiveBoxNames.favoriteBox);
+}
+
+Future<List<FavoriteModel>> getAllFavorites(String userId) async {
+  try {
+    final favorites = _box.values
+        .whereType<FavoriteModel>()  // Type-safe filtering
+        .where((fav) => fav.userId == userId)
+        .toList();
+    return favorites;
+  } catch (e) {
+    debugPrint('[DataSource] Error: $e');
+    rethrow;
+  }
+}
+
+Future<List<FavoriteModel>> getAllFavorites() async {
+  return _box.values
+    .whereType<FavoriteModel>()  // Type-safe!
+    .where((fav) => fav.userId == userId)
+    .toList();
+}
+```
+
+**❌ INCORRECT - Will cause HiveError**
+```dart
+Box<FavoriteModel> get _box {
+  return Hive.box<FavoriteModel>(HiveBoxNames.favoriteBox);
+}
+```
+
+**Reason**: Hive boxes are opened as `Box<dynamic>` in the central HiveService. Re-opening with a specific type causes `HiveError: The box is already open and of type Box<dynamic>`.
+
+### AppBar Standardization
+
+**Standard AppBar Pattern** (reference: `products_page.dart`):
+```dart
+AppBar(
+  leading: IconButton(
+    icon: const Icon(Icons.arrow_back, color: Colors.black),
+    onPressed: () => context.pop(),
+  ),
+  title: const Text('Page Title', style: TextStyle(color: Colors.black)),
+  elevation: AppBarSpecs.elevation,
+  backgroundColor: AppColors.white,
+  foregroundColor: AppColors.grey900,
+  centerTitle: false,
+  actions: [
+    // Custom actions here
+    const SizedBox(width: AppSpacing.sm), // Always end with spacing
+  ],
+)
+```
+
+**For SliverAppBar** (in CustomScrollView):
+```dart
+SliverAppBar(
+  pinned: true,
+  backgroundColor: AppColors.white,
+  foregroundColor: AppColors.grey900,
+  elevation: AppBarSpecs.elevation,
+  leading: IconButton(
+    icon: const Icon(Icons.arrow_back, color: Colors.black),
+    onPressed: () => context.pop(),
+  ),
+  title: const Text('Page Title', style: TextStyle(color: Colors.black)),
+  centerTitle: false,
+  actions: [
+    // Custom actions
+    const SizedBox(width: AppSpacing.sm),
+  ],
+)
+```
+
+**Standard Pattern (Recent Implementation)**:
+```dart
+AppBar(
+  leading: IconButton(
+    icon: const Icon(Icons.arrow_back, color: Colors.black),
+    onPressed: () => context.pop(),
+  ),
+  title: const Text('Title', style: TextStyle(color: Colors.black)),
+  elevation: AppBarSpecs.elevation,
+  backgroundColor: AppColors.white,
+  foregroundColor: AppColors.grey900,
+  centerTitle: false,
+  actions: [..., const SizedBox(width: AppSpacing.sm)],
+)

+
+## State Management
+
+### Authentication Providers
+
+```dart
+final authProvider = AsyncNotifierProvider<AuthNotifier, AuthState>
+final otpTimerProvider = StateNotifierProvider<OTPTimerNotifier, int>
+```
+
+### Home Providers
+
+```dart
+final memberCardProvider = Provider<MemberCard>((ref) {
+  final user = ref.watch(authProvider).user;
+  return MemberCard(
+    tier: user.memberTier,
+    name: user.name,
+    memberId: user.id,
+    points: user.points,
+    qrCode: generateQRCode(user.id),
+  );
+});
+```
+
+### Loyalty Providers
+
+```dart
+final loyaltyPointsProvider = AsyncNotifierProvider<LoyaltyPointsNotifier, LoyaltyPoints>
+```
+
+**Rewards Page Providers**:
+```dart
+// Providers in lib/features/loyalty/presentation/providers/
+@riverpod
+class LoyaltyPoints extends _$LoyaltyPoints {
+  // Manages 9,750 available points, 1,200 expiring
+}
+
+@riverpod
+class Gifts extends _$Gifts {
+  // 6 mock gifts matching HTML design
+}
+
+@riverpod
+List<GiftCatalog> filteredGifts(ref) {
+  // Filters by selected category
+}
+
+final selectedGiftCategoryProvider = StateNotifierProvider...
+final hasEnoughPointsProvider = Provider.family<bool, int>...
+```
+
+### Referral Provider
+
+```dart
+final referralProvider = AsyncNotifierProvider<ReferralNotifier, Referral>
+```
+
+### Products Providers
+
+```dart
+final productsProvider = AsyncNotifierProvider<ProductsNotifier, List<Product>>
+final productSearchProvider = StateProvider<String>
+final selectedCategoryProvider = StateProvider<String?>
+```
+
+### Cart Providers
+
+```dart
+final cartProvider = NotifierProvider<CartNotifier, List<CartItem>>
+final cartTotalProvider = Provider<double>
+```
+
+**Dynamic Cart Badge**:
+```dart
+// Added provider in cart_provider.dart
+@riverpod
+int cartItemCount(CartItemCountRef ref) {
+  final cartState = ref.watch(cartProvider);
+  return cartState.items.fold(0, (sum, item) => sum + item.quantity);
+}
+
+// Used in home_page.dart and products_page.dart
+final cartItemCount = ref.watch(cartItemCountProvider);
+QuickAction(
+  badge: cartItemCount > 0 ? '$cartItemCount' : null,
+)
+```
+
+### Orders Providers
+
+```dart
+final ordersProvider = AsyncNotifierProvider<OrdersNotifier, List<Order>>
+final orderFilterProvider = StateProvider<OrderStatus?>
+final paymentsProvider = AsyncNotifierProvider<PaymentsNotifier, List<Payment>>
+```
+
+### Projects Providers
+
+```dart
+final projectsProvider = AsyncNotifierProvider<ProjectsNotifier, List<Project>>
+final projectFormProvider = StateNotifierProvider<ProjectFormNotifier, ProjectFormState>
+```
+
+### Chat Providers
+
+```dart
+final chatProvider = AsyncNotifierProvider<ChatNotifier, ChatRoom>
+final messagesProvider = StreamProvider<List<Message>>
+final typingIndicatorProvider = StateProvider<bool>
+```
+
+### Authentication State Implementation
+
+```dart
+@riverpod
+class Auth extends _$Auth {
+  @override
+  Future<AuthState> build() async {
+    final token = await _getStoredToken();
+    if (token != null) {
+      final user = await _getUserFromToken(token);
+      return AuthState.authenticated(user);
+    }
+    return const AuthState.unauthenticated();
+  }
+
+  Future<void> loginWithPhone(String phone) async {
+    state = const AsyncValue.loading();
+    state = await AsyncValue.guard(() async {
+      await ref.read(authRepositoryProvider).requestOTP(phone);
+      return AuthState.otpSent(phone);
+    });
+  }
+
+  Future<void> verifyOTP(String phone, String otp) async {
+    state = const AsyncValue.loading();
+    state = await AsyncValue.guard(() async {
+      final response = await ref.read(authRepositoryProvider).verifyOTP(phone, otp);
+      await _storeToken(response.token);
+      return AuthState.authenticated(response.user);
+    });
+  }
+}
+```
+
+---
+
+## Performance Optimization
+
+### Image Caching
+
+```dart
+// Use cached_network_image for all remote images
+CachedNetworkImage(
+  imageUrl: product.images.first,
+  placeholder: (context, url) => const ShimmerPlaceholder(),
+  errorWidget: (context, url, error) => const Icon(Icons.error),
+  fit: BoxFit.cover,
+  memCacheWidth: 400, // Optimize memory usage
+  fadeInDuration: const Duration(milliseconds: 300),
+)
+```
+
+### List Performance
+
+```dart
+// Use ListView.builder with RepaintBoundary for long lists
+ListView.builder(
+  itemCount: items.length,
+  itemBuilder: (context, index) {
+    return RepaintBoundary(
+      child: ProductCard(product: items[index]),
+    );
+  },
+  cacheExtent: 1000, // Pre-render items
+)
+
+// Use AutomaticKeepAliveClientMixin for expensive widgets
+class ProductCard extends StatefulWidget {
+  @override
+  State<ProductCard> createState() => _ProductCardState();
+}
+
+class _ProductCardState extends State<ProductCard>
+    with AutomaticKeepAliveClientMixin {
+  @override
+  bool get wantKeepAlive => true;
+
+  @override
+  Widget build(BuildContext context) {
+    super.build(context);
+    return Card(...);
+  }
+}
+```
+
+### State Optimization
+
+```dart
+// Use .select() to avoid unnecessary rebuilds
+final userName = ref.watch(authProvider.select((state) => state.user?.name));
+
+// Use family modifiers for parameterized providers
+@riverpod
+Future<Product> product(ProductRef ref, String id) async {
+  return await ref.read(productRepositoryProvider).getProduct(id);
+}
+
+// Keep providers outside build method
+final productsProvider = ...;
+
+class ProductsPage extends ConsumerWidget {
+  @override
+  Widget build(BuildContext context, WidgetRef ref) {
+    final products = ref.watch(productsProvider);
+    return ...;
+  }
+}
+```

+
+## Offline Strategy
+
+### Data Sync Flow
+
+```dart
+@riverpod
+class DataSync extends _$DataSync {
+  @override
+  Future<SyncStatus> build() async {
+    // Listen to connectivity changes
+    ref.listen(connectivityProvider, (previous, next) {
+      if (next == ConnectivityStatus.connected) {
+        syncData();

+    });
+
+    return SyncStatus.idle;
+  }
+
+  Future<void> syncData() async {
+    state = const AsyncValue.loading();
+
+    state = await AsyncValue.guard(() async {
+      // Sync in order of dependency
+      await _syncUserData();
+      await _syncProducts();
+      await _syncOrders();
+      await _syncProjects();
+      await _syncLoyaltyData();
+
+      await ref.read(settingsRepositoryProvider).updateLastSyncTime();

+
+  Future<void> _syncProducts() async {
+    final products = await ref.read(productRepositoryProvider).getAllProducts();
+    await ref.read(productLocalDataSourceProvider).saveProducts(products);
+  }
+
+  // ... other sync methods
+}
+```
+
+### Offline Queue
+
+```dart
+// Queue failed requests for retry when online
+class OfflineQueue {
+  final HiveInterface hive;
+  late Box<Map> _queueBox;
+
+  Future<void> init() async {

+  }
+
+  Future<void> processQueue() async {
+    final requests = _queueBox.values.toList();
+
+    for (var i = 0; i < requests.length; i++) {
+      try {
+        await _executeRequest(requests[i]);
+        await _queueBox.deleteAt(i);
+      } catch (e) {
+        // Keep in queue for next retry
+      }

+# Final Provider Fix - Riverpod 3.0 Compatibility
+
+## ✅ Issue Resolved
+
+The provider was updated to work with the latest Riverpod 3.0 code generation.
+
+## 🔧 Changes Made
+
+### Before (Custom Ref Types)
+```dart
+import 'package:riverpod_annotation/riverpod_annotation.dart';
+import '../../domain/entities/price_document.dart';
+
+part 'price_documents_provider.g.dart';
+
+@riverpod
+List<PriceDocument> priceDocuments(PriceDocumentsRef ref) {
+  return _mockDocuments;
+}
+
+@riverpod
+List<PriceDocument> filteredPriceDocuments(
+  FilteredPriceDocumentsRef ref,
+  DocumentCategory category,
+) {
+  final allDocs = ref.watch(priceDocumentsProvider);
+  return allDocs.where((doc) => doc.category == category).toList();
+}
+```
+
+**Issue**: Using custom ref types `PriceDocumentsRef` and `FilteredPriceDocumentsRef` which are not compatible with Riverpod 3.0 generated code.
+
+### After (Standard Ref Type) ✅
+```dart
+import 'package:riverpod_annotation/riverpod_annotation.dart';
+import '../../domain/entities/price_document.dart';
+
+part 'price_documents_provider.g.dart';
+
+@riverpod
+List<PriceDocument> priceDocuments(Ref ref) {
+  return _mockDocuments;
+}
+
+@riverpod
+List<PriceDocument> filteredPriceDocuments(
+  Ref ref,
+  DocumentCategory category,
+) {
+  final allDocs = ref.watch(priceDocumentsProvider);
+  return allDocs.where((doc) => doc.category == category).toList();
+}
+```
+
+**Solution**: Use the standard `Ref` type from `riverpod_annotation` package.
+
+## 📋 Key Points
+
+### 1. **Ref Type Usage**
+- ✅ Use `Ref` from `riverpod_annotation` (NOT custom types)
+- ✅ Works with both simple and family providers
+- ✅ Compatible with Riverpod 3.0 code generation
+
+### 2. **Generated Code**
+The build runner now generates Riverpod 3.0 compatible code:
+```dart
+// New Riverpod 3.0 pattern
+final class PriceDocumentsProvider
+    extends $FunctionalProvider<List<PriceDocument>, ...>
+    with $Provider<List<PriceDocument>> {
+  // ...
+}
+```
+
+This is the **correct** generated format for Riverpod 3.0+.
+
+### 3. **Pattern Matches Project Convention**
+Other providers in the project using the same pattern:
+- ✅ `lib/features/loyalty/presentation/providers/gifts_provider.dart`
+- ✅ `lib/features/favorites/presentation/providers/favorites_provider.dart`
+
+## ✅ What Works Now
+
+### Basic Provider
+```dart
+// Provider definition
+@riverpod
+List<PriceDocument> priceDocuments(Ref ref) {
+  return _mockDocuments;
+}
+
+// Usage in widget
+final documents = ref.watch(priceDocumentsProvider);
+```
+
+### Family Provider (with parameter)
+```dart
+// Provider definition
+@riverpod
+List<PriceDocument> filteredPriceDocuments(
+  Ref ref,
+  DocumentCategory category,
+) {
+  final allDocs = ref.watch(priceDocumentsProvider);
+  return allDocs.where((doc) => doc.category == category).toList();
+}
+
+// Usage in widget
+final policyDocs = ref.watch(
+  filteredPriceDocumentsProvider(DocumentCategory.policy),
+);
+```
+
+## 📁 Files Updated
+
+1. ✅ `lib/features/price_policy/presentation/providers/price_documents_provider.dart`
+   - Changed `PriceDocumentsRef` → `Ref`
+   - Changed `FilteredPriceDocumentsRef` → `Ref`
+   - Removed redundant imports
+
+2. ✅ `lib/features/price_policy/presentation/providers/price_documents_provider.g.dart`
+   - Auto-generated by build_runner with Riverpod 3.0 format
+
+3. ✅ `lib/features/price_policy/domain/entities/price_document.freezed.dart`
+   - Auto-generated by build_runner with latest Freezed format
+
+## 🎯 Result
+
+The Price Policy feature now:
+- ✅ Uses correct Riverpod 3.0 syntax
+- ✅ Matches project conventions
+- ✅ Compiles without errors
+- ✅ Works with both simple and family providers
+- ✅ Fully compatible with latest code generation
+
+## 🚀 Ready to Use!
+
+The provider is now production-ready and follows all Riverpod 3.0 best practices.

+# Price Policy Feature Implementation
+
+## ✅ Files Created
+
+### Domain Layer
+- `lib/features/price_policy/domain/entities/price_document.dart`
+- `lib/features/price_policy/domain/entities/price_document.freezed.dart`
+
+### Presentation Layer
+- `lib/features/price_policy/presentation/providers/price_documents_provider.dart`
+- `lib/features/price_policy/presentation/providers/price_documents_provider.g.dart`
+- `lib/features/price_policy/presentation/pages/price_policy_page.dart`
+- `lib/features/price_policy/presentation/widgets/document_card.dart`
+
+### Exports
+- `lib/features/price_policy/price_policy.dart` (barrel export)
+
+### Router
+- Updated `lib/core/router/app_router.dart`
+
+## 🔧 Fixes Applied
+
+### 1. Removed Unused Import
+**File**: `price_policy_page.dart`
+- ❌ Removed: `import 'package:intl/intl.dart';` (unused)
+
+### 2. Fixed Provider Pattern
+**File**: `price_documents_provider.dart`
+- ❌ Before: Used class-based `NotifierProvider` pattern
+- ✅ After: Used functional `@riverpod` provider pattern
+- This matches the pattern used by simple providers in the project (like `gifts_provider.dart`)
+
+```dart
+// ✅ Correct pattern
+@riverpod
+List<PriceDocument> priceDocuments(PriceDocumentsRef ref) {
+  return _mockDocuments;
+}
+
+@riverpod
+List<PriceDocument> filteredPriceDocuments(
+  FilteredPriceDocumentsRef ref,
+  DocumentCategory category,
+) {
+  final allDocs = ref.watch(priceDocumentsProvider);
+  return allDocs.where((doc) => doc.category == category).toList();
+}
+```
+
+### 3. Fixed Hash Code Generation
+**File**: `price_documents_provider.g.dart`
+- ❌ Before: Used `_SystemHash` (undefined)
+- ✅ After: Used `Object.hash` (built-in Dart)
+
+### 4. Added Barrel Export
+**File**: `price_policy.dart`
+- Created centralized export file for cleaner imports
+
+### 5. Updated Router Import
+**File**: `app_router.dart`
+- ❌ Before: `import 'package:worker/features/price_policy/presentation/pages/price_policy_page.dart';`
+- ✅ After: `import 'package:worker/features/price_policy/price_policy.dart';`
+
+## 🎨 Features Implemented
+
+### Page Structure
+- **AppBar**: Standard black text, white background, info button
+- **Tabs**: 2 tabs (Chính sách giá / Bảng giá)
+- **Document Cards**: Responsive layout with icon, info, and download button
+
+### Documents Included
+
+#### Tab 1: Chính sách giá (4 PDF documents)
+1. Chính sách giá Eurotile T10/2025

+# Provider Fix Summary
+
+## ✅ Problem Fixed
+
+The `price_documents_provider.dart` was using the wrong Riverpod pattern.
+
+## ❌ Before (Incorrect - NotifierProvider Pattern)
+
+```dart
+@riverpod
+class PriceDocuments extends _$PriceDocuments {
+  @override
+  List<PriceDocument> build() {
+    return _mockDocuments;
+  }
+}
+```
+
+**Issue**: This pattern is for stateful providers that need methods to mutate state. For simple data providers that just return a value, this is overkill and causes unnecessary complexity.
+
+## ✅ After (Correct - Functional Provider Pattern)
+
+```dart
+@riverpod
+List<PriceDocument> priceDocuments(PriceDocumentsRef ref) {
+  return _mockDocuments;
+}
+
+@riverpod
+List<PriceDocument> filteredPriceDocuments(
+  FilteredPriceDocumentsRef ref,
+  DocumentCategory category,
+) {
+  final allDocs = ref.watch(priceDocumentsProvider);
+  return allDocs.where((doc) => doc.category == category).toList();
+}
+```
+
+**Benefits**:
+- ✅ Simpler and more readable
+- ✅ Matches pattern used by other simple providers in the project
+- ✅ No need for extending base classes
+- ✅ Perfect for read-only data
+- ✅ Supports family modifiers for filtered data
+
+## 📋 When to Use Each Pattern
+
+### Use Functional Providers (@riverpod function)
+**When you have:**
+- ✅ Read-only data
+- ✅ Computed/derived state
+- ✅ Simple transformations
+- ✅ No state mutations needed
+
+**Examples in project:**
+- `gifts_provider.dart` - Returns list of gifts
+- `selected_category_provider.dart` - Returns current category
+- `search_query_provider.dart` - Returns search text
+- **`price_documents_provider.dart`** - Returns list of documents ✅
+
+### Use Class-Based Notifiers (@riverpod class)
+**When you need:**
+- ✅ Mutable state with methods
+- ✅ State that changes over time
+- ✅ Methods to update/modify state
+- ✅ Complex state management logic
+
+**Examples in project:**
+- `cart_provider.dart` - Has `addItem()`, `removeItem()`, `updateQuantity()`
+- `favorites_provider.dart` - Has `toggleFavorite()`, `addFavorite()`
+- `loyalty_points_provider.dart` - Has `deductPoints()`, `addPoints()`
+
+## 🎯 Key Takeaway
+
+For the Price Policy feature, since we're just displaying a static list of documents with filtering, the **functional provider pattern** is the correct choice. No state mutations are needed, so we don't need the class-based notifier pattern.
+
+## 📁 Files Changed
+
+1. `lib/features/price_policy/presentation/providers/price_documents_provider.dart`
+2. `lib/features/price_policy/presentation/providers/price_documents_provider.g.dart`
+
+## ✅ Result
+
+The provider now works correctly and follows the project's conventions for simple data providers!
