 ### 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

+## 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)],
+)

+```
+
+### Home Providers
+
+```dart

+    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

+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

+
+### Offline Queue
+
+```dart

+        await _executeRequest(requests[i]);
+        await _queueBox.deleteAt(i);
+      } catch (e) {

+# 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`

+
+### 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';`

+# 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!

+      excerpt:
+          'Khám phá những mẫu gạch men hiện đại, sang trọng cho không gian phòng tắm. Từ những tone màu trung tính đến các họa tiết độc đáo, cùng tìm hiểu các xu hướng đang được yêu thích nhất.',
+      content: '''
+<p>Năm 2024 đánh dấu sự trở lại mạnh mẽ của các thiết kế phòng tắm hiện đại với những xu hướng gạch men đột phá. Không chỉ đơn thuần là vật liệu ốp lát, gạch men ngày nay đã trở thành yếu tố quyết định phong cách và cảm xúc của không gian.</p>
+
+<h2>1. Gạch men họa tiết đá tự nhiên</h2>
+<p>Xu hướng bắt chước kết cấu và màu sắc của đá tự nhiên đang trở nên cực kỳ phổ biến. Các sản phẩm gạch men mô phỏng đá marble, granite hay travertine mang đến vẻ đẹp sang trọng mà vẫn đảm bảo tính thực tiễn cao.</p>
+
+<highlight type="tip">Chọn gạch men vân đá với kích thước lớn (60x120cm trở lên) để tạo cảm giác không gian rộng rãi và giảm số đường nối.</highlight>
+
+<h2>2. Tone màu trung tính và earth tone</h2>
+<p>Các gam màu trung tính như be, xám nhạt, và các tone đất đang thống trị xu hướng thiết kế. Những màu sắc này không chỉ tạo cảm giác thư giãn mà còn dễ dàng kết hợp với nhiều phong cách nội thất khác nhau.</p>
+
+<ul>
+<li>Beige và cream: Tạo cảm giác ấm áp, thân thiện</li>
+<li>Xám nhạt: Hiện đại, tinh tế và sang trọng</li>
+<li>Nâu đất: Gần gũi với thiên nhiên, tạo cảm giác thư thái</li>
+</ul>
+
+<h2>3. Kích thước lớn và định dạng dài</h2>
+<p>Gạch men kích thước lớn (60x120cm, 75x150cm) và định dạng dài đang được ưa chuộng vì khả năng tạo ra không gian liền mạch, giảm đường nối và dễ vệ sinh.</p>
+
+<blockquote>"Việc sử dụng gạch men kích thước lớn không chỉ tạo vẻ hiện đại mà còn giúp phòng tắm nhỏ trông rộng rãi hơn đáng kể" - KTS Nguyễn Minh Tuấn</blockquote>
+
+<h2>4. Bề mặt texture và 3D</h2>
+<p>Các loại gạch men với bề mặt có texture hoặc hiệu ứng 3D đang tạo nên điểm nhấn thú vị cho không gian phòng tắm. Từ các họa tiết geometric đến surface sần sùi tự nhiên.</p>
+
+<h3>Các loại texture phổ biến:</h3>
+<ol>
+<li>Matt finish: Bề mặt nhám, chống trượt tốt</li>
+<li>Structured surface: Có kết cấu sần sùi như đá tự nhiên</li>
+<li>3D geometric: Họa tiết nổi tạo hiệu ứng thị giác</li>
+</ol>
+
+<h2>5. Gạch men màu đen và tương phản cao</h2>
+<p>Xu hướng sử dụng gạch men màu đen hoặc tạo tương phản mạnh đang được nhiều gia chủ lựa chọn để tạo điểm nhấn đặc biệt cho phòng tắm.</p>
+
+<highlight type="warning">Gạch men màu tối dễ để lại vết ố từ nước cứng và xà phòng. Cần vệ sinh thường xuyên và sử dụng sản phẩm chống thấm phù hợp.</highlight>
+
+<h2>Kết luận</h2>
+<p>Xu hướng gạch men phòng tắm năm 2024 hướng tới sự kết hợp hoàn hảo giữa thẩm mỹ và tính năng. Việc lựa chọn đúng loại gạch men không chỉ tăng giá trị thẩm mỹ mà còn đảm bảo độ bền và dễ bảo trì trong thời gian dài.</p>
+
+<p>Hãy tham khảo ý kiến của chuyên gia và cân nhắc kỹ về điều kiện sử dụng thực tế để đưa ra lựa chọn phù hợp nhất cho không gian của bạn.</p>
