|
||||
|
||||
## State Management Architecture
|
||||
|
||||
### State Flow
|
||||
```
|
||||
User Action (Add/Remove Favorite)
|
||||
↓
|
||||
favoritesProvider.notifier.addFavorite(productId)
|
||||
↓
|
||||
Update Hive Database (FavoritesLocalDataSource)
|
||||
↓
|
||||
Update In-Memory State (Set<String>)
|
||||
↓
|
||||
Notify Listeners (UI Rebuilds)
|
||||
```
|
||||
|
||||
### Data Persistence
|
||||
- **Primary Storage**: Hive (local database)
|
||||
- **Box Name**: `favorite_box` (from HiveBoxNames.favoriteBox)
|
||||
- **Model**: `FavoriteModel` (Hive TypeId: 28)
|
||||
- **Format**:
|
||||
```dart
|
||||
FavoriteModel(
|
||||
favoriteId: "user_001_product_123_1234567890",
|
||||
productId: "product_123",
|
||||
userId: "user_001",
|
||||
createdAt: DateTime.now(),
|
||||
)
|
||||
```
|
||||
|
||||
### State Type
|
||||
- **Type**: `Set<String>` (Product IDs)
|
||||
- **Reason**: Set provides O(1) lookup for `.contains()` checks
|
||||
- **Alternative**: Could use `List<String>` but Set is more efficient
|
||||
|
||||
---
|
||||
|
||||
## Integration Points
|
||||
|
||||
### ✅ Already Integrated
|
||||
1. **Hive Database**
|
||||
- Uses existing `HiveBoxNames.favoriteBox`
|
||||
- Uses existing `HiveTypeIds.favoriteModel` (28)
|
||||
- FavoriteModel already has generated adapter
|
||||
|
||||
2. **Domain Layer**
|
||||
- `Favorite` entity: `/lib/features/favorites/domain/entities/favorite.dart`
|
||||
- `FavoriteModel`: `/lib/features/favorites/data/models/favorite_model.dart`
|
||||
|
||||
### ⚠️ TODO: Authentication Integration
|
||||
Currently using hardcoded userId (`'user_001'`). To integrate with auth:
|
||||
|
||||
1. **Locate Auth Provider** (when available)
|
||||
2. **Update `currentUserIdProvider`**:
|
||||
```dart
|
||||
@riverpod
|
||||
String currentUserId(Ref ref) {
|
||||
final authState = ref.watch(authProvider);
|
||||
return authState.user?.id ?? 'guest';
|
||||
}
|
||||
```
|
||||
|
||||
3. **Handle Guest Users**:
|
||||
- Decide: Should guests have favorites?
|
||||
- If yes, use device-specific ID
|
||||
- If no, show login prompt when favoriting
|
||||
|
||||
---
|
||||
|
||||
## Usage in Widgets
|
||||
|
||||
### Example 1: Simple Favorite Button
|
||||
```dart
|
||||
class FavoriteButton extends ConsumerWidget {
|
||||
final String productId;
|
||||
|
||||
@override
|
||||
Widget build(BuildContext context, WidgetRef ref) {
|
||||
final isFavorited = ref.watch(isFavoriteProvider(productId));
|
||||
|
||||
return IconButton(
|
||||
icon: Icon(isFavorited ? Icons.favorite : Icons.favorite_border),
|
||||
onPressed: () {
|
||||
ref.read(favoritesProvider.notifier).toggleFavorite(productId);
|
||||
},
|
||||
);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Example 2: Favorites Count Badge
|
||||
```dart
|
||||
class FavoritesBadge extends ConsumerWidget {
|
||||
@override
|
||||
Widget build(BuildContext context, WidgetRef ref) {
|
||||
final count = ref.watch(favoriteCountProvider);
|
||||
|
||||
return Badge(
|
||||
label: Text('$count'),
|
||||
child: Icon(Icons.favorite),
|
||||
);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Example 3: Display All Favorites
|
||||
```dart
|
||||
class FavoritesPage extends ConsumerWidget {
|
||||
@override
|
||||
Widget build(BuildContext context, WidgetRef ref) {
|
||||
final favoritesAsync = ref.watch(favoritesProvider);
|
||||
|
||||
return favoritesAsync.when(
|
||||
data: (favorites) => ListView.builder(
|
||||
itemCount: favorites.length,
|
||||
itemBuilder: (context, index) {
|
||||
final productId = favorites.elementAt(index);
|
||||
return ProductCard(productId: productId);
|
||||
},
|
||||
),
|
||||
loading: () => CircularProgressIndicator(),
|
||||
error: (error, stack) => Text('Error: $error'),
|
||||
);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**See `USAGE_EXAMPLES.md` for comprehensive examples.**
|
||||
|
||||

|
||||
|
||||
## Testing
|
||||
|
||||
### Unit Test Example
|
||||
```dart
|
||||
import 'package:flutter_test/flutter_test.dart';
|
||||
import 'package:flutter_riverpod/flutter_riverpod.dart';
|
||||
|
||||
void main() {
|
||||
test('should add and remove favorites', () async {
|
||||
final container = ProviderContainer();
|
||||
addTearDown(container.dispose);
|
||||
|
||||
// Add favorite
|
||||
await container.read(favoritesProvider.notifier)
|
||||
.addFavorite('product_1');
|
||||
|
||||
// Verify added
|
||||
final favorites = await container.read(favoritesProvider.future);
|
||||
expect(favorites, contains('product_1'));
|
||||
|
||||
// Remove favorite
|
||||
await container.read(favoritesProvider.notifier)
|
||||
.removeFavorite('product_1');
|
||||
|
||||
// Verify removed
|
||||
final updated = await container.read(favoritesProvider.future);
|
||||
expect(updated, isNot(contains('product_1')));
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Error Handling
|
||||
|
||||
### State Management Errors
|
||||
- Wrapped in `AsyncValue.error()`
|
||||
- UI can handle with `.when()` method
|
||||
- Logged to console with debug messages
|
||||
|
||||
### Database Errors
|
||||
- Try-catch blocks in datasource methods
|
||||
- Rethrow for provider to handle
|
||||
- Graceful fallbacks (empty sets, false returns)
|
||||
|
||||
### Edge Cases Handled
|
||||
- ✅ Product already favorited (no-op)
|
||||
- ✅ Product not in favorites (no-op on remove)
|
||||
- ✅ Empty favorites list
|
||||
- ✅ Hive box not initialized
|
||||
- ✅ Multi-user support (filters by userId)
|
||||
|
||||
---
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Optimizations
|
||||
1. **Set vs List**: Using `Set<String>` for O(1) lookup
|
||||
2. **Auto-dispose**: All providers auto-dispose when not in use
|
||||
3. **Selective watching**: `isFavoriteProvider` rebuilds only affected widgets
|
||||
4. **Database compaction**: Available via `compact()` method
|
||||
5. **Sorted by date**: Favorites returned in newest-first order
|
||||
|
||||
### Potential Improvements
|
||||
1. **Batch operations**: Add `addMultipleFavorites()` method
|
||||
2. **Caching**: Add in-memory cache layer
|
||||
3. **Pagination**: For users with many favorites
|
||||
4. **Sync**: Add remote API sync capability
|
||||
|
||||
---
|
||||
|
||||
## Debugging
|
||||
|
||||
### Console Logs
|
||||
All operations log to console with prefix `[FavoritesProvider]` or `[FavoritesLocalDataSource]`:
|
||||
- "Added favorite: product_123"
|
||||
- "Removed favorite: product_123 for user: user_001"
|
||||
- "Loaded 5 favorites for user: user_001"
|
||||
- "Error adding favorite: ..."
|
||||
|
||||
### Check State
|
||||
```dart
|
||||
// In widget
|
||||
final favorites = ref.read(favoritesProvider);
|
||||
print('Favorites state: $favorites');
|
||||
|
||||
// Check if favorited
|
||||
final isFav = ref.read(isFavoriteProvider('product_123'));
|
||||
print('Is favorited: $isFav');
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Known Limitations
|
||||
|
||||
1. **No Auth Integration Yet**: Using hardcoded userId
|
||||
2. **No Remote Sync**: Only local storage (Hive)
|
||||
3. **No Offline Queue**: Changes not synced to backend
|
||||
4. **Single Device**: No cross-device synchronization
|
||||
5. **No Favorites Limit**: Could grow unbounded
|
||||
|
||||
---
|
||||
|
||||
## Next Steps
|
||||
|
||||
### Immediate Tasks
|
||||
1. ✅ ~~Create providers~~ (Complete)
|
||||
2. ✅ ~~Create datasource~~ (Complete)
|
||||

|
||||
class ProductCard extends ConsumerWidget {
|
||||
final String productId;
|
||||
|
||||
@override

||||
}
|
||||
```
|
||||
|
||||
### Favorites Count Badge
|
||||
```dart
|
||||
class FavoriteBadge extends ConsumerWidget {
|
||||
@override
|
||||
Widget build(BuildContext context, WidgetRef ref) {

|
||||
|
||||
return Badge(

||||
label: Text('$count'),
|
||||
child: Icon(Icons.favorite),
|
||||
);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Display All Favorites
|
||||
```dart
|
||||
class FavoritesPage extends ConsumerWidget {
|
||||
@override
|
||||
Widget build(BuildContext context, WidgetRef ref) {
|
||||
final favoritesAsync = ref.watch(favoritesProvider);
|
||||
|
||||
return favoritesAsync.when(
|
||||
data: (favorites) => ListView.builder(
|
||||
itemCount: favorites.length,
|
||||
itemBuilder: (context, index) {
|
||||
final productId = favorites.elementAt(index);
|
||||
return ProductTile(productId: productId);
|
||||
},
|
||||
),
|
||||
loading: () => CircularProgressIndicator(),
|
||||
error: (error, stack) => ErrorWidget(error),
|
||||
);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🔧 Provider Methods
|
||||
|
||||
### Main Provider (`favoritesProvider.notifier`)
|
||||
|
||||
| Method | Description |
|
||||
|--------|-------------|
|
||||
| `addFavorite(productId)` | Add product to favorites |
|
||||
| `removeFavorite(productId)` | Remove product from favorites |
|
||||
| `toggleFavorite(productId)` | Toggle favorite status |
|
||||
| `refresh()` | Reload favorites from database |
|
||||
| `clearAll()` | Remove all favorites |
|
||||
|
||||
---
|
||||
|
||||
## 💾 Data Persistence
|
||||
|
||||
- **Storage**: Hive local database
|
||||
- **Box**: `favorite_box` (HiveBoxNames.favoriteBox)
|
||||
- **Model**: `FavoriteModel` (TypeId: 28)
|
||||
- **Fields**:
|
||||
- `favoriteId`: Unique ID (userId_productId_timestamp)
|
||||
- `productId`: Product reference
|
||||
- `userId`: User reference
|
||||
- `createdAt`: Timestamp
|
||||
|
||||
---
|
||||
|
||||
## ⚠️ Important Notes
|
||||
|
||||
### TODO: Auth Integration
|
||||
Currently using hardcoded userId (`'user_001'`). Replace when auth is ready:
|
||||
|
||||
```dart
|
||||
// In favorites_provider.dart
|
||||
@riverpod
|
||||
String currentUserId(Ref ref) {
|
||||
// TODO: Replace with actual auth provider
|
||||
final user = ref.watch(authProvider).user;
|
||||
return user?.id ?? 'guest';
|
||||
}
|
||||
```
|
||||
|
||||
### Hive Box Initialization
|
||||
Ensure the favorites box is opened in `main.dart`:
|
||||
|
||||
```dart
|
||||
await Hive.openBox<FavoriteModel>(HiveBoxNames.favoriteBox);
|
||||
```

||||
| Issue | Solution |
|
||||
|-------|----------|
|
||||
| Favorites not persisting | Check Hive box initialization in `main.dart` |
|
||||
| State not updating | Use `ref.read()` for mutations, `ref.watch()` for listening |
|
||||
| Performance issues | Use `isFavoriteProvider` instead of watching full `favoritesProvider` |

# Favorites Provider - Usage Examples
|
||||
|
||||
This document provides practical examples of how to use the Favorites state management provider in the Worker app.
|
||||
|
||||
## Overview
|
||||
|
||||
The Favorites feature provides a complete state management solution for managing user's favorite products using Riverpod 3.0 with code generation and Hive for local persistence.
|
||||
|
||||
## Provider Structure
|
||||
|
||||
```dart
|
||||
// Main providers
|
||||
favoritesProvider // AsyncNotifier<Set<String>>
|
||||
favoritesLocalDataSourceProvider // FavoritesLocalDataSource
|
||||
currentUserIdProvider // String (TODO: replace with auth)
|
||||
|
||||
// Helper providers
|
||||
isFavoriteProvider(productId) // bool
|
||||
favoriteCountProvider // int
|
||||
favoriteProductIdsProvider // List<String>
|
||||
```
|
||||
|
||||

### 5. Filter Products to Show Only Favorites
|
||||
|
||||
```dart
|
||||
import 'package:flutter_riverpod/flutter_riverpod.dart';
|
||||
import 'package:worker/features/favorites/presentation/providers/favorites_provider.dart';
|
||||
import 'package:worker/features/products/presentation/providers/products_provider.dart';
|
||||
|
||||
// Create a derived provider for favorite products
|
||||
@riverpod
|
||||
Future<List<Product>> favoriteProducts(Ref ref) async {

|
||||
|
||||
// Filter products
|
||||
return products.where((p) => favoriteIds.contains(p.id)).toList();
|
||||
}
|
||||
|
||||
// Usage in widget
|
||||
class FavoriteProductsList extends ConsumerWidget {
|

### 6. Refresh Favorites from Database
|
||||
|
||||
```dart
|
||||
import 'package:flutter/material.dart';
|
||||
import 'package:flutter_riverpod/flutter_riverpod.dart';
|
||||
import 'package:worker/features/favorites/presentation/providers/favorites_provider.dart';
|
||||
|
||||
class FavoritesPageWithRefresh extends ConsumerWidget {
|
||||
const FavoritesPageWithRefresh({super.key});
|
||||
|
||||
@override
|
||||
Widget build(BuildContext context, WidgetRef ref) {
|
||||
final favoritesAsync = ref.watch(favoritesProvider);
|
||||
|
||||
return Scaffold(
|
||||
appBar: AppBar(
|
||||
title: const Text('My Favorites'),
|
||||
actions: [
|
||||
IconButton(
|
||||
icon: const Icon(Icons.refresh),
|
||||
onPressed: () {
|
||||
// Refresh favorites from database
|
||||
ref.read(favoritesProvider.notifier).refresh();
|
||||
},
|
||||
),
|
||||
],
|
||||
),
|
||||
body: RefreshIndicator(
|
||||
onRefresh: () async {
|
||||
// Pull to refresh
|
||||
await ref.read(favoritesProvider.notifier).refresh();
|
||||
},
|
||||
child: favoritesAsync.when(
|
||||
data: (favorites) => ListView.builder(
|
||||
itemCount: favorites.length,
|
||||
itemBuilder: (context, index) {
|
||||
final productId = favorites.elementAt(index);
|
||||
return ListTile(title: Text('Product: $productId'));
|
||||
},
|
||||
),
|
||||
loading: () => const Center(child: CircularProgressIndicator()),
|
||||
error: (error, stack) => Center(child: Text('Error: $error')),
|
||||
),
|

## Advanced Usage
|
||||
|
||||
### 7. Handle Loading States with Custom UI
|
||||
|
||||
```dart
|
||||
import 'package:flutter/material.dart';
|
||||
import 'package:flutter_riverpod/flutter_riverpod.dart';
|
||||
import 'package:worker/features/favorites/presentation/providers/favorites_provider.dart';
|
||||
|
||||
class FavoriteButtonWithLoadingState extends ConsumerWidget {
|
||||
final String productId;
|
||||
|
||||
const FavoriteButtonWithLoadingState({
|
||||
super.key,
|
||||
required this.productId,
|
||||
});
|
||||
|
||||
@override
|
||||
Widget build(BuildContext context, WidgetRef ref) {
|
||||
final favoritesAsync = ref.watch(favoritesProvider);
|
||||
|
||||
return favoritesAsync.when(
|
||||
data: (favorites) {
|
||||
final isFavorited = favorites.contains(productId);
|
||||
|
||||
return IconButton(
|
||||
icon: Icon(
|
||||
isFavorited ? Icons.favorite : Icons.favorite_border,
|
||||
color: isFavorited ? Colors.red : Colors.grey,
|
||||
),
|
||||
onPressed: () {
|
||||
ref.read(favoritesProvider.notifier).toggleFavorite(productId);
|
||||
},
|
||||
);
|
||||
},
|
||||
loading: () => const SizedBox(
|
||||
width: 24,
|
||||
height: 24,
|
||||
child: CircularProgressIndicator(strokeWidth: 2),
|
||||
),
|
||||
error: (error, stack) => IconButton(
|
||||
icon: const Icon(Icons.error, color: Colors.grey),
|
||||
onPressed: () {
|
||||
ref.invalidate(favoritesProvider);
|
||||
},
|
||||
),
|
||||
);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 8. Sync Favorites on App Resume
|
||||
|
||||
```dart
|
||||
import 'package:flutter/material.dart';
|
||||
import 'package:flutter_riverpod/flutter_riverpod.dart';
|
||||
import 'package:worker/features/favorites/presentation/providers/favorites_provider.dart';
|
||||
|
||||
class FavoritesAppLifecycleManager extends ConsumerStatefulWidget {
|
||||
final Widget child;
|
||||
|
||||
const FavoritesAppLifecycleManager({
|
||||
super.key,
|
||||
required this.child,
|
||||
});
|
||||
|
||||
@override
|
||||
ConsumerState<FavoritesAppLifecycleManager> createState() =>
|
||||
_FavoritesAppLifecycleManagerState();
|
||||
}
|
||||
|
||||
class _FavoritesAppLifecycleManagerState
|
||||
extends ConsumerState<FavoritesAppLifecycleManager>
|
||||
with WidgetsBindingObserver {
|
||||
@override
|
||||
void initState() {
|
||||
super.initState();
|
||||
WidgetsBinding.instance.addObserver(this);
|
||||
}
|
||||
|
||||
@override
|
||||
void dispose() {
|
||||
WidgetsBinding.instance.removeObserver(this);
|
||||
super.dispose();
|
||||
}
|
||||
|
||||
@override
|
||||
void didChangeAppLifecycleState(AppLifecycleState state) {
|
||||
if (state == AppLifecycleState.resumed) {
|
||||
// Refresh favorites when app resumes
|
||||
ref.read(favoritesProvider.notifier).refresh();
|
||||
}
|
||||
}
|
||||
|
||||
@override
|
||||
Widget build(BuildContext context) {
|
||||
return widget.child;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Integration with Auth Provider (TODO)
|
||||
|
||||
Once the authentication provider is available, update the `currentUserId` provider:
|
||||
|
||||
```dart
|
||||
// In favorites_provider.dart
|
||||
|
||||
/// Provides the current logged-in user's ID
|
||||
@riverpod
|
||||
String currentUserId(Ref ref) {
|
||||
// Replace this with actual auth integration:
|
||||
final authState = ref.watch(authProvider);
|
||||
return authState.user?.id ?? 'guest';
|
||||
|
||||
// Or throw an error if user is not logged in:
|
||||
// final user = ref.watch(authProvider).user;
|
||||
// if (user == null) throw Exception('User not logged in');
|
||||
// return user.id;
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Testing Examples
|
||||
|
||||
### Unit Test Example
|
||||
|
||||
```dart
|
||||
import 'package:flutter_test/flutter_test.dart';
|
||||
import 'package:flutter_riverpod/flutter_riverpod.dart';
|
||||
import 'package:worker/features/favorites/presentation/providers/favorites_provider.dart';
|
||||
|
||||
void main() {
|
||||
test('should add favorite to state', () async {
|
||||
final container = ProviderContainer();
|
||||
addTearDown(container.dispose);
|
||||
|
||||
// Initial state should be empty
|
||||
final initialState = await container.read(favoritesProvider.future);
|
||||
expect(initialState, isEmpty);
|
||||
|
||||
// Add favorite
|
||||
await container.read(favoritesProvider.notifier).addFavorite('product_1');
|
||||
|
||||
// Check if favorite was added
|
||||
final updatedState = await container.read(favoritesProvider.future);
|
||||
expect(updatedState, contains('product_1'));
|
||||
});
|
||||
|
||||
test('isFavorite should return true for favorited product', () async {
|
||||
final container = ProviderContainer();
|
||||
addTearDown(container.dispose);
|
||||
|
||||
// Add favorite
|
||||
await container.read(favoritesProvider.notifier).addFavorite('product_1');
|
||||
|
||||
// Check if product is favorited
|
||||
final isFavorited = container.read(isFavoriteProvider('product_1'));
|
||||
expect(isFavorited, isTrue);
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Performance Tips
|
||||
|
||||
1. **Use `isFavoriteProvider` for individual checks** - This prevents rebuilding all favorite-dependent widgets when the favorites list changes.
|
||||
|
||||
2. **Use `.select()` for specific data** - If you only need a specific piece of data:
|
||||
```dart
|
||||
final hasFavorites = ref.watch(
|
||||
favoritesProvider.select((async) => async.value?.isNotEmpty ?? false)
|
||||
);
|
||||
```
|
||||
|
||||
3. **Avoid unnecessary rebuilds** - Wrap expensive widgets with `RepaintBoundary` or use `Consumer` to isolate rebuilds.
|
||||
|
||||
4. **Batch operations** - If adding/removing multiple favorites, consider implementing a batch operation method.
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Favorites not persisting
|
||||
- Ensure Hive box is properly initialized in `main.dart`
|
||||
- Check that the favorite box is opened: `Hive.openBox<FavoriteModel>(HiveBoxNames.favoriteBox)`
|
||||
|
||||
### State not updating
|
||||
- Verify you're using `ref.read()` for mutations and `ref.watch()` for listening
|
||||
- Check console logs for error messages
|
||||
|
||||
### Performance issues
|
||||
- Use `isFavoriteProvider` instead of watching the entire `favoritesProvider`
|
||||
- Implement pagination for large favorite lists
|
||||
- Consider compacting the Hive box periodically
|
||||
|
||||
---
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. **Integrate with Auth Provider** - Replace hardcoded userId with actual user from auth state
|
||||
2. **Add Remote Sync** - Implement API calls to sync favorites with backend
|
||||
3. **Analytics** - Track favorite actions for user insights
|
||||
4. **Recommendations** - Use favorite data to recommend similar products
