# Products Feature
This feature implements the complete products catalog browsing functionality for the Worker mobile app using clean architecture principles.
## Architecture
The feature follows a clean architecture pattern with three distinct layers:
### Domain Layer (`domain/`)
Pure business logic with no dependencies on Flutter or data sources.
- **Entities** (`entities/`):
- `Product`: Product business entity with price calculations, stock status, and discount logic
- `Category`: Product category for filtering
- **Repositories** (`repositories/`):
- `ProductsRepository`: Abstract interface defining data operations
- **Use Cases** (`usecases/`):
- `GetProducts`: Retrieve products with optional category filtering
- `SearchProducts`: Search products by query string
- `GetCategories`: Retrieve all product categories
### Data Layer (`data/`)
Handles data persistence and retrieval.
- **Models** (`models/`):
- `ProductModel`: Hive-compatible product data model (Type ID: 20)
- `CategoryModel`: Hive-compatible category data model (Type ID: 21)
- **Data Sources** (`datasources/`):
- `ProductsLocalDataSource`: Mock data provider with 10 sample products across 6 categories
- **Repositories** (`repositories/`):
- `ProductsRepositoryImpl`: Concrete implementation of ProductsRepository
### Presentation Layer (`presentation/`)
UI components and state management.
- **Providers** (`providers/`):
- `ProductsProvider`: Main provider for filtered products (category + search)
- `CategoriesProvider`: Categories list provider
- `SelectedCategoryProvider`: Current selected category state
- `SearchQueryProvider`: Current search query state
- `AllProductsProvider`: Unfiltered products provider
- **Pages** (`pages/`):
- `ProductsPage`: Main products browsing page with search, filters, and grid
- **Widgets** (`widgets/`):
- `ProductSearchBar`: Search input with clear button
- `CategoryFilterChips`: Horizontal scrolling category chips
- `ProductCard`: Product display card with image, price, stock status, and add to cart
- `ProductGrid`: 2-column responsive grid layout
## Features
### Product Display
- 2-column responsive grid layout
- Product image with caching (cached_network_image)
- Product name, SKU, and price
- Price per unit display (e.g., "450.000đ/m²")
- Sale price with discount badge
- Stock status indicator
- Low stock warning badge
- Add to cart button
### Filtering & Search
- Real-time search across product name, SKU, and description
- Category filtering with 6 categories:
- Tất cả (All)
- Gạch lát nền (Floor tiles)
- Gạch ốp tường (Wall tiles)
- Gạch trang trí (Decorative tiles)
- Gạch ngoài trời (Outdoor tiles)
- Phụ kiện (Accessories)
- Combined search + category filtering
### UI/UX Features
- Pull-to-refresh support
- Loading states with CircularProgressIndicator
- Error states with retry button
- Empty states with helpful messages
- Vietnamese localization
- Material 3 design system
- Responsive layout
- Optimized image caching
- Smooth scrolling performance
## Mock Data
The feature includes 10 sample products:
1. **Gạch men cao cấp 60x60** - Premium glazed tiles (450.000đ/m²)
2. **Gạch granite nhập khẩu** - Imported granite (680.000đ/m², sale: 620.000đ)
3. **Gạch mosaic trang trí** - Decorative mosaic (320.000đ/m²)
4. **Gạch 3D họa tiết** - 3D patterned tiles (750.000đ/m², sale: 680.000đ)
5. **Gạch ceramic chống trượt** - Anti-slip ceramic (380.000đ/m²)
6. **Gạch terrazzo đá mài** - Terrazzo tiles (890.000đ/m², sale: 820.000đ)
7. **Gạch ốp tường bếp** - Kitchen wall tiles (280.000đ/m²)
8. **Gạch sân vườn chống rêu** - Anti-mold garden tiles (420.000đ/m², sale: 380.000đ)
9. **Keo dán gạch chuyên dụng** - Tile adhesive (180.000đ/bao)
10. **Keo chà ron màu** - Colored grout (120.000đ/bao, sale: 99.000đ)
All products include:
- High-quality Unsplash images
- Detailed Vietnamese descriptions
- Brand attribution (Eurotile or Vasta Stone)
- Stock quantities
- Created timestamps
## State Management
The feature uses Riverpod 3.0 with code generation:
```dart
// Watch products (filtered by category and search)
final productsAsync = ref.watch(productsProvider);
// Update search query
ref.read(searchQueryProvider.notifier).updateQuery('gạch men');
// Update selected category
ref.read(selectedCategoryProvider.notifier).updateCategory('floor_tiles');
// Refresh products
await ref.read(productsProvider.notifier).refresh();
```
## Navigation
The products page is registered in the app router:
```dart
context.goProducts(); // Navigate to products page
context.go(RouteNames.products); // Using route name
```
## Dependencies
- `flutter_riverpod`: ^3.0.0 - State management
- `riverpod_annotation`: ^3.0.0 - Code generation
- `hive_ce`: ^2.6.0 - Local database
- `cached_network_image`: ^3.3.1 - Image caching
- `shimmer`: ^3.0.0 - Loading placeholders
- `intl`: ^0.20.0 - Vietnamese number formatting
- `go_router`: ^14.6.2 - Navigation
## Future Enhancements
- [ ] Product detail page
- [ ] Add to cart functionality
- [ ] Cart state management
- [ ] Product favorites/wishlist
- [ ] Advanced filters (price range, brand, etc.)
- [ ] Sort options (price, name, popularity)
- [ ] Load more / pagination
- [ ] Product comparison
- [ ] Recent viewed products
- [ ] Related products recommendations
- [ ] API integration (replace mock data)
## Testing
To run tests for this feature:
```bash
# Unit tests
flutter test test/features/products/domain/
flutter test test/features/products/data/
# Widget tests
flutter test test/features/products/presentation/widgets/
# Integration tests
flutter test integration_test/products_test.dart
```
## Code Generation
After making changes to providers or models, run:
```bash
dart run build_runner build --delete-conflicting-outputs
```

Navigator.push(
context,
MaterialPageRoute(builder: (_) => const ProductsPage()),
);
}
// Or using go_router
