## 🤖 SUBAGENT DELEGATION SYSTEM 🤖
**CRITICAL: BE PROACTIVE WITH SUBAGENTS! YOU HAVE SPECIALIZED EXPERTS AVAILABLE!**
### 🚨 DELEGATION MINDSET
**Instead of thinking "I'll handle this myself"** **Think: "Which specialist is BEST suited for this task?"**
### 📋 AVAILABLE SPECIALISTS
You have access to these expert subagents - USE THEM PROACTIVELY:
#### 🎨 **flutter-widget-expert**
- **MUST BE USED for**: Loyalty cards, member cards, product grids, order cards, project cards, chat UI, form layouts, bottom navigation
- **Triggers**: "create widget", "build UI", "card design", "layout", "animation", "custom widget", "loyalty card", "member card"
#### 📊 **riverpod-expert**
- **MUST BE USED for**: Cart state, authentication state, loyalty points state, product state, order state, project state
- **Triggers**: "state management", "provider", "riverpod", "async state", "data flow", "cart", "auth state"
#### 🗄️ **hive-expert**
- **MUST BE USED for**: Local database, offline storage, cart persistence, user data caching, loyalty points cache
- **Triggers**: "database", "cache", "hive", "local storage", "persistence", "offline", "box"
#### 🌐 **api-integration-expert**
- **MUST BE USED for**: Authentication API, OTP verification, product API, loyalty API, order API, project API
- **Triggers**: "API", "HTTP", "dio", "REST", "backend", "authentication", "OTP", "sync"

- **Triggers**: "performance", "optimization", "memory", "image cache", "slow", "lag", "scroll"
### 🎯 DELEGATION STRATEGY
**BEFORE starting ANY task, ASK YOURSELF:**
1. "Which of my specialists could handle this better?"
2. "Should I break this into parts for different specialists?"
3. "Would a specialist complete this faster and better?"
### 💼 WORK BALANCE RECOMMENDATION:
- **Simple Tasks (20%)**: Handle independently - quick fixes, minor updates
- **Complex Tasks (80%)**: Delegate to specialists for expert-level results
### 🔧 HOW TO DELEGATE
```
# Explicit delegation examples:
> Use the flutter-widget-expert to create the Diamond/Platinum/Gold loyalty card widget
> Have the riverpod-expert design the authentication and user session state management
> Ask the hive-expert to create the local database schema for products and orders
> Use the api-integration-expert to implement OTP authentication flow
> Have the architecture-expert organize the loyalty program feature structure
> Ask the performance-expert to optimize the product grid scrolling
```
---
## Flutter Best Practices
- Use Flutter 3.x features and Material 3 design
- Implement clean architecture with Riverpod for state management
- Use Hive for local database and offline functionality
- Follow proper dependency injection with Riverpod DI
- Implement proper error handling and user feedback
- Follow iOS and Android platform-specific design guidelines
- Support Vietnamese language (primary) and English (secondary)
- Mobile-first design optimized for phone screens
### 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);
}
```
**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
**ALL AppBars must follow this standard 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
],
)
```
**Key Requirements**:
- Black back arrow with explicit color
- Black text title with TextStyle
- Left-aligned title (`centerTitle: false`)
- White background (`AppColors.white`)
- Use `AppBarSpecs.elevation` (not hardcoded values)
- Always add `SizedBox(width: AppSpacing.sm)` after actions
**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),
],
)
```

);
static const goldGradient = LinearGradient(
colors: [Color(0xFFf7b733), Color(0xFFfc4a1a)],
begin: Alignment.topLeft,
end: Alignment.bottomRight,
);
}
```
### Typography
```dart
// typography.dart
class AppTypography {
static const fontFamily = 'Roboto';
static const displayLarge = TextStyle(
fontSize: 32,
fontWeight: FontWeight.bold,
fontFamily: fontFamily,
);
static const headlineLarge = TextStyle(
fontSize: 24,
fontWeight: FontWeight.w600,
fontFamily: fontFamily,
);
static const titleLarge = TextStyle(
fontSize: 20,
fontWeight: FontWeight.w500,
fontFamily: fontFamily,
);
static const bodyLarge = TextStyle(
fontSize: 16,
fontWeight: FontWeight.normal,
fontFamily: fontFamily,
);
static const labelSmall = TextStyle(
fontSize: 12,
fontWeight: FontWeight.normal,
fontFamily: fontFamily,
);
}
```
### Component Specifications
#### Member Card Design
```dart
class MemberCardSpecs {
static const double width = double.infinity;
static const double height = 200;
static const double borderRadius = 16;
static const double elevation = 8;
static const EdgeInsets padding = EdgeInsets.all(20);
// QR Code
static const double qrSize = 80;
static const double qrBackgroundSize = 90;
// Points Display
static const double pointsFontSize = 28;
static const FontWeight pointsFontWeight = FontWeight.bold;
}
```
#### Status Badges
```dart
class StatusBadge extends StatelessWidget {
final String status;
final Color color;
static Color getColorForStatus(OrderStatus status) {
switch (status) {
case OrderStatus.pending:
return AppColors.info;
case OrderStatus.processing:
return AppColors.warning;
case OrderStatus.shipping:
return AppColors.lightBlue;
case OrderStatus.completed:
return AppColors.success;
case OrderStatus.cancelled:
return AppColors.danger;
}
}
}
```
#### Bottom Navigation
```dart
class BottomNavSpecs {
static const double height = 72;
static const double iconSize = 24;
static const double selectedIconSize = 28;
static const double labelFontSize = 12;
static const Color selectedColor = AppColors.primaryBlue;
static const Color unselectedColor = AppColors.grey500;
}
```
#### Floating Action Button
```dart
class FABSpecs {
static const double size = 56;
static const double elevation = 6;
static const Color backgroundColor = AppColors.accentCyan;
static const Color iconColor = Colors.white;
static const double iconSize = 24;
static const Offset position = Offset(16, 16); // from bottom-right
}
```
#### AppBar (Standardized across all pages)
```dart
class AppBarSpecs {
// From ui_constants.dart
static const double elevation = 0.5;
// Standard pattern for all pages
static AppBar standard({
required String title,
required VoidCallback onBack,
List<Widget>? actions,
}) {
return AppBar(
leading: IconButton(
icon: const Icon(Icons.arrow_back, color: Colors.black),
onPressed: onBack,
),
title: Text(title, style: const TextStyle(color: Colors.black)),
elevation: elevation,
backgroundColor: AppColors.white,
foregroundColor: AppColors.grey900,
centerTitle: false,
actions: [
...?actions,
const SizedBox(width: AppSpacing.sm),
],
);
}
}
```
**Usage Notes**:
- ALL pages use this standard AppBar pattern
- Back arrow is always black with explicit color
- Title is always left-aligned (`centerTitle: false`)
- Title text is always black
- Background is always white
- Actions always end with `SizedBox(width: AppSpacing.sm)` spacing
- For SliverAppBar, add `pinned: true` property

## Technical Architecture
### State Management (Riverpod 2.x)
#### Authentication State
```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();
return SyncStatus.success;
});
}
Future<void> _syncUserData() async {
final user = await ref.read(authRepositoryProvider).getCurrentUser();
await ref.read(authLocalDataSourceProvider).saveUser(user);
}
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 {
_queueBox = await hive.openBox('offline_queue');
}
Future<void> addToQueue(ApiRequest request) async {
await _queueBox.add({
'endpoint': request.endpoint,
'method': request.method,
'body': request.body,
'timestamp': DateTime.now().toIso8601String(),
});
}
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
}
}
}
}
```

## Recent Updates & Implementation Notes (December 2024)
### ✅ Rewards/Gift Redemption System
**Status**: Fully implemented with mock data
**Implementation Details**:
1. **Providers** (`lib/features/loyalty/presentation/providers/`):
- `loyalty_points_provider.dart` - Manages user points (9,750 available, 1,200 expiring)
- `gifts_provider.dart` - 6 mock gifts matching HTML design
- `selectedGiftCategoryProvider` - Category filter state
- `filteredGiftsProvider` - Category-based filtering
- `hasEnoughPointsProvider.family` - Points validation per gift
2. **Widgets** (`lib/features/loyalty/presentation/widgets/`):
- `points_balance_card.dart` - Gradient blue card with points display
- `reward_card.dart` - Gift card with bottom-aligned action button
3. **Pages** (`lib/features/loyalty/presentation/pages/`):
- `rewards_page.dart` - Main screen with RefreshIndicator
4. **Route**: `/loyalty/rewards` in `app_router.dart`
**Key Features**:
- 2-column grid layout with `childAspectRatio: 0.7`
- Category filtering: Tất cả/Voucher/Sản phẩm/Dịch vụ/Ưu đãi đặc biệt
- Bottom-aligned buttons using `Expanded` + `Spacer()`
- Redemption dialog with points calculation
- Success feedback with SnackBar
### ✅ AppBar Standardization
**Status**: Completed across all pages
**Standard Pattern**:
```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)],
)
```
**Updated Pages**:
- `cart_page.dart` - Lines 84-103
- `favorites_page.dart` - Lines 79-115
- `rewards_page.dart` - Lines 35-48
- `promotion_detail_page.dart` - Lines 59-86 (loading/error), 130-161 (SliverAppBar)
- `product_detail_page.dart` - Already correct ✅
### ✅ Dynamic Cart Badge
**Status**: Implemented across home and products pages
**Implementation**:
```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,
)
```
**Behavior**:
- Shows total quantity across all cart items
- Hidden when cart is empty
- Updates in real-time via Riverpod
- Navigation via `RouteNames.cart` constant
### ✅ Hive Box Type Management
**Status**: Best practices documented and implemented
**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 {
