## How Bearer Token is Injected
|
||||
|
||||
### Automatic Token Injection Flow
|
||||
|
||||
```
|
||||
1. User logs in or registers
|
||||
↓
|
||||
2. JWT token received from API
|
||||
↓
|
||||
3. Token saved to secure storage
|
||||
↓
|
||||
4. Token set in DioClient: dioClient.setAuthToken(token)
|
||||
↓
|
||||
5. Dio interceptor automatically adds header to ALL requests:
|
||||
Authorization: Bearer {token}
|
||||
↓
|
||||
6. All subsequent API calls include the token
|
||||
```
|
||||
|
||||
### Implementation
|
||||
|
||||
```dart
|
||||
// In lib/core/network/dio_client.dart
|
||||
class DioClient {
|
||||
String? _authToken;
|
||||
|
||||
DioClient() {
|
||||
// Auth interceptor adds token to all requests
|
||||
_dio.interceptors.add(
|
||||
InterceptorsWrapper(
|
||||
onRequest: (options, handler) {
|
||||
if (_authToken != null) {
|
||||
options.headers['Authorization'] = 'Bearer $_authToken';
|
||||
}
|
||||
return handler.next(options);
|
||||
},
|
||||
),
|
||||
);
|
||||
}
|
||||
|
||||
void setAuthToken(String token) => _authToken = token;
|
||||
void clearAuthToken() => _authToken = null;
|
||||
}
|
||||
```
|
||||
|
||||
### When Token is Set
|
||||
|
||||
1. **On Login Success:**
|
||||
```dart
|
||||
await secureStorage.saveAccessToken(token);
|
||||
dioClient.setAuthToken(token);
|
||||
```
|
||||
|
||||
2. **On Register Success:**
|
||||
```dart
|
||||
await secureStorage.saveAccessToken(token);
|
||||
dioClient.setAuthToken(token);
|
||||
```
|
||||
|
||||
3. **On App Start:**
|
||||
```dart
|
||||
final token = await secureStorage.getAccessToken();
|
||||
if (token != null) {
|
||||
dioClient.setAuthToken(token);
|
||||
}
|
||||
```
|
||||
|
||||
4. **On Token Refresh:**
|
||||
```dart
|
||||
await secureStorage.saveAccessToken(newToken);
|
||||
dioClient.setAuthToken(newToken);
|
||||
```
|
||||
|
||||
### When Token is Cleared
|
||||
|
||||
1. **On Logout:**
|
||||
```dart
|
||||
await secureStorage.deleteAllTokens();
|
||||
dioClient.clearAuthToken();
|
||||
```

||||

|
||||
## How to Use Auth in the App
|
||||
|
||||
### 1. Initialize Dependencies
|
||||
|
||||
Already configured in `main.dart`:
|
||||
|
||||
```dart
|
||||
void main() async {
|
||||
WidgetsFlutterBinding.ensureInitialized();
|
||||
|
||||
// Initialize dependencies (includes auth setup)
|
||||
await initDependencies();
|
||||
|
||||
runApp(const ProviderScope(child: MyApp()));
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Login User
|
||||
|
||||
```dart
|
||||
import 'package:flutter_riverpod/flutter_riverpod.dart';
|
||||
import 'package:retail/features/auth/presentation/providers/auth_provider.dart';
|
||||
|
||||
class LoginWidget extends ConsumerWidget {
|
||||
@override
|
||||
Widget build(BuildContext context, WidgetRef ref) {
|
||||
return ElevatedButton(
|
||||
onPressed: () async {
|
||||
final success = await ref.read(authProvider.notifier).login(
|
||||
email: 'user@example.com',
|
||||
password: 'Password123!',
|
||||
);
|
||||
|
||||
if (success) {
|
||||
Navigator.pushReplacementNamed(context, '/home');
|
||||
} else {
|
||||
final error = ref.read(authProvider).errorMessage;
|
||||
ScaffoldMessenger.of(context).showSnackBar(
|
||||
SnackBar(content: Text(error ?? 'Login failed')),
|
||||
);
|
||||
}
|
||||
},
|
||||
child: Text('Login'),
|
||||
);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Register User
|
||||
|
||||
```dart
|
||||
final success = await ref.read(authProvider.notifier).register(
|
||||
name: 'John Doe',
|
||||
email: 'john@example.com',
|
||||
password: 'Password123!',
|
||||
roles: ['user'], // Optional
|
||||
);
|
||||
```
|
||||
|
||||
### 4. Check Authentication Status
|
||||
|
||||
```dart
|
||||
// Method 1: Watch isAuthenticated
|
||||
final isAuthenticated = ref.watch(isAuthenticatedProvider);
|
||||
|
||||
if (isAuthenticated) {
|
||||
// Show home page
|
||||
} else {
|
||||
// Show login page
|
||||
}
|
||||
|
||||
// Method 2: Get current user
|
||||
final user = ref.watch(currentUserProvider);
|
||||
|
||||
if (user != null) {
|
||||
print('Welcome ${user.name}!');
|
||||
print('Is Admin: ${user.isAdmin}');
|
||||
}
|
||||
```
|
||||
|
||||
### 5. Protected Routes
|
||||
|
||||
```dart
|
||||
class AuthGuard extends ConsumerWidget {
|
||||
final Widget child;
|
||||
|
||||
const AuthGuard({required this.child});
|
||||
|
||||
@override
|
||||
Widget build(BuildContext context, WidgetRef ref) {
|
||||
final isAuthenticated = ref.watch(isAuthenticatedProvider);
|
||||
final isLoading = ref.watch(authProvider.select((s) => s.isLoading));
|
||||
|
||||
if (isLoading) {
|
||||
return Scaffold(body: Center(child: CircularProgressIndicator()));
|
||||
}
|
||||
|
||||
if (!isAuthenticated) {
|
||||
return LoginPage();
|
||||
}
|
||||
|
||||
return child;
|
||||
}
|
||||
}
|
||||
|
||||
// Usage:
|
||||
MaterialApp(
|
||||
home: AuthGuard(child: HomePage()),
|
||||
);
|
||||
```
|
||||
|
||||
### 6. Logout User
|
||||
|
||||
```dart
|
||||
await ref.read(authProvider.notifier).logout();
|
||||
Navigator.pushReplacementNamed(context, '/login');
|
||||
```
|
||||
|
||||
### 7. Role-Based Access Control
|
||||
|
||||
```dart
|
||||
final user = ref.watch(currentUserProvider);
|
||||
|
||||
// Check admin role
|
||||
if (user?.isAdmin ?? false) {
|
||||
// Show admin panel
|
||||
}
|
||||
|
||||
// Check manager role
|
||||
if (user?.isManager ?? false) {
|
||||
// Show manager tools
|
||||
}
|
||||
|
||||
// Check custom role
|
||||
if (user?.hasRole('cashier') ?? false) {
|
||||
// Show cashier features
|
||||
}
|
||||
```
|
||||
|
||||
### 8. Refresh Token
|
||||
|
||||
```dart
|
||||
final success = await ref.read(authProvider.notifier).refreshToken();
|
||||
|
||||
if (!success) {
|
||||
// Token refresh failed, user logged out automatically
|
||||
Navigator.pushReplacementNamed(context, '/login');
|
||||
}
|
||||
```
|
||||
|
||||
### 9. Get User Profile (Refresh)
|
||||
|
||||
```dart
|
||||
await ref.read(authProvider.notifier).getProfile();
|
||||
```
|
||||

## 🔑 API Endpoints Used
|
||||
|
||||
**Base URL:** `http://localhost:3000`
|
||||
|
||||
### Authentication

|
||||
|
||||
## 🚀 Quick Start Guide
|
||||
|
||||
### 1. Start Your Backend
|
||||
```bash
|
||||
# Make sure your NestJS backend is running
|
||||
# at http://localhost:3000
|
||||
npm run start:dev
|
||||
```
|
||||
|
||||
### 2. Run the App
|
||||
```bash
|
||||
flutter run
|
||||
```
|
||||
|
||||
### 3. Test Login
|
||||
Use credentials from your backend:
|
||||
```
|
||||
Email: admin@retailpos.com
|
||||
Password: Admin123!
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 💡 How It Works
|
||||
|
||||
### Automatic Bearer Token Flow
|
||||
|
||||
```
|
||||
┌─────────────┐
|
||||
│ User Logs In │
|
||||
└──────┬──────┘
|
||||
│
|
||||
▼
|
||||
┌─────────────────────────┐
|
||||
│ Token Saved to Keychain │
|
||||
└──────┬──────────────────┘
|
||||
│
|
||||
▼
|
||||
┌────────────────────────┐
|
||||
│ Token Set in DioClient │
|
||||
└──────┬─────────────────┘
|
||||
│
|
||||
▼
|
||||
┌────────────────────────────────────┐
|
||||
│ ALL Future API Calls Include: │
|
||||
│ Authorization: Bearer {your-token} │
|
||||
└────────────────────────────────────┘
|
||||
```
|
||||
|
||||
**Key Point:** After login, you NEVER need to manually add tokens. The Dio interceptor handles it automatically!

## 📝 Usage Examples
|
||||
|
||||
### Example 1: Login User
|
||||
```dart
|
||||
import 'package:flutter_riverpod/flutter_riverpod.dart';
|
||||
import 'package:retail/features/auth/presentation/providers/auth_provider.dart';
|
||||
|
||||
// In your widget
|
||||
final success = await ref.read(authProvider.notifier).login(
|
||||
email: 'user@example.com',
|
||||
password: 'Password123!',
|
||||
);
|
||||
|
||||
if (success) {
|
||||
// Login successful! Token automatically saved and set
|
||||
Navigator.pushReplacementNamed(context, '/home');
|
||||
} else {
|
||||
// Show error
|
||||
final error = ref.read(authProvider).errorMessage;
|
||||
ScaffoldMessenger.of(context).showSnackBar(
|
||||
SnackBar(content: Text(error ?? 'Login failed')),
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### Example 2: Check Authentication
|
||||
```dart
|
||||
// Watch authentication status
|
||||
final isAuthenticated = ref.watch(isAuthenticatedProvider);
|
||||
|
||||
if (isAuthenticated) {
|
||||
// User is logged in
|
||||
final user = ref.watch(currentUserProvider);
|
||||
print('Welcome ${user?.name}!');
|
||||
}
|
||||
```
|
||||
|
||||
### Example 3: Get User Info
|
||||
```dart
|
||||
final user = ref.watch(currentUserProvider);
|
||||
|
||||
if (user != null) {
|
||||
print('Name: ${user.name}');
|
||||
print('Email: ${user.email}');
|
||||
print('Roles: ${user.roles.join(', ')}');
|
||||
|
||||
// Check roles
|
||||
if (user.isAdmin) {
|
||||
// Show admin features
|
||||
}
|
||||
if (user.isManager) {
|
||||
// Show manager features
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Example 4: Logout
|
||||
```dart
|
||||
await ref.read(authProvider.notifier).logout();
|
||||
// Token cleared, user redirected to login
|
||||
```
|
||||
|
||||
### Example 5: Protected Widget
|
||||
```dart
|
||||
class ProtectedRoute extends ConsumerWidget {
|
||||
final Widget child;
|
||||
|
||||
@override
|
||||
Widget build(BuildContext context, WidgetRef ref) {
|
||||
final isAuthenticated = ref.watch(isAuthenticatedProvider);
|
||||
|
||||
if (!isAuthenticated) {
|
||||
return LoginPage();
|
||||
}
|
||||
|
||||
return child;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Example 6: Role-Based Access
|
||||
```dart
|
||||
class AdminOnly extends ConsumerWidget {
|
||||
final Widget child;
|
||||
|
||||
@override
|
||||
Widget build(BuildContext context, WidgetRef ref) {
|
||||
final user = ref.watch(currentUserProvider);
|
||||
|
||||
if (user?.isAdmin != true) {
|
||||
return Center(child: Text('Admin access required'));
|
||||
}
|
||||
|
||||
return child;
|
||||
}
|
||||
}
|
||||
```

||||
If your backend is not at `localhost:3000`:
|
||||
|
||||
```dart
|
||||
// lib/core/constants/api_constants.dart
|
||||
static const String baseUrl = 'YOUR_API_URL_HERE';
|

// Example: 'https://api.yourapp.com'
|
||||
```
|
||||
|
||||
### Default Test Credentials
|
||||
Create a test user in your backend:
|
||||
```json
|
||||
{
|
||||
"name": "Test User",
|
||||
"email": "test@retailpos.com",
|
||||
"password": "Test123!",
|
||||
"roles": ["user"]
|
||||
}
|
||||
```
|
||||

## 🔐 Security Features
|
||||
|
||||
### Secure Token Storage
|
||||
- Uses `flutter_secure_storage` package
|
||||
- iOS: Keychain
|
||||
- Android: EncryptedSharedPreferences
|
||||
- Web: Secure web storage
|
||||
- Windows/Linux: Encrypted local storage
|
||||
|
||||
### Token Management
|
||||
```dart
|
||||
// Automatic token refresh before expiry
|
||||
await ref.read(authProvider.notifier).refreshToken();
|
||||
|
||||
// Manual token check
|
||||
final hasToken = await ref.read(authProvider.notifier).hasValidToken();
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🧪 Testing
|
||||
|
||||
### Test Authentication Flow
|
||||
```bash
|
||||
flutter run
|
||||
```
|
||||
|
||||
1. App opens → Should show Login page
|
||||
2. Enter credentials → Click Login
|
||||
3. Success → Navigates to Home
|
||||
4. Check Network tab → All API calls have `Authorization: Bearer ...`
|
||||
|
||||
### Verify Token Injection
|
||||
```dart
|
||||
// Make any API call after login - token is automatically added
|
||||
final products = await productsApi.getAll();
|
||||
// Header automatically includes: Authorization: Bearer {token}
|
||||
```

## 🎨 Customization
|
||||
|
||||
### Update Login UI
|
||||
Edit: `lib/features/auth/presentation/pages/login_page.dart`
|
||||
|
||||
### Add Social Login
|
||||
Extend `AuthRepository` with:
|
||||
```dart
|
||||
Future<Either<Failure, AuthResponse>> loginWithGoogle();
|
||||
Future<Either<Failure, AuthResponse>> loginWithApple();
|
||||
```
|
||||
|
||||
### Add Password Reset
|
||||
1. Add endpoint to Swagger
|
||||
2. Add method to `AuthRemoteDataSource`
|
||||
3. Update `AuthRepository`
|
||||
4. Create UI page
|
||||
|
||||
---
|
||||
|
||||
## ⚠️ Important Notes
|
||||
|
||||
### Backend Requirements
|
||||
- Your NestJS backend must be running
|
||||
- Endpoints must match Swagger spec
|
||||
- CORS must be configured if running on web
|
||||
|
||||
### Token Expiry
|
||||
- Tokens expire based on backend configuration
|
||||
- Implement auto-refresh or logout on expiry
|
||||
- Current implementation: Manual refresh available
|
||||
|
||||
### Testing Without Backend
|
||||
If backend is not ready:
|
||||
```dart
|
||||
// Use mock mode in api_constants.dart
|
||||
static const bool useMockData = true;
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🚦 Status Indicators
|
||||
|
||||
### Authentication State
|
||||
```dart
|
||||
final authState = ref.watch(authProvider);
|
||||
|
||||
// Check status
|
||||
authState.isLoading // Currently authenticating
|
||||
authState.isAuthenticated // User is logged in
|
||||
authState.errorMessage // Error if failed
|
||||
authState.user // Current user info
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🔄 Integration with Existing Features
|
||||
|
||||
### Products Feature
|
||||
Products API calls automatically authenticated:
|
||||
```dart
|
||||
// After login, these calls include bearer token
|
||||
final products = await getProducts(); // ✅ Authenticated
|
||||
final product = await getProduct(id); // ✅ Authenticated
|
||||
```
|
||||
|
||||
### Categories Feature
|
||||
Public endpoints (no auth needed):
|
||||
```dart
|
||||
final categories = await getCategories(); // Public
|
||||
```
|
||||
|
||||
Protected endpoints (admin only):
|
||||
```dart
|
||||
await createCategory(data); // ✅ Authenticated with admin role
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🎯 Next Steps
|
||||
|
||||
### 1. Start Backend
|
||||
```bash
|
||||
cd your-nestjs-backend

|
||||
- Products should load from backend
|
||||
- Categories should load from backend
|
||||
- All calls should include bearer token
|
||||
|
||||
### 4. (Optional) Customize UI
|
||||
- Update colors in theme
|
||||
- Modify login/register forms
|
||||

|
||||
|
||||
---
|
||||
|
||||
## 📞 Troubleshooting
|
||||
|
||||
### "Connection refused" Error
|
||||
✅ **Fix:** Ensure backend is running at `http://localhost:3000`
|
||||
|
||||
### "Invalid token" Error
|
||||
✅ **Fix:** Token expired, logout and login again
|
||||
|
||||
### Token not being added to requests
|
||||
✅ **Fix:** Check that `DioClient.setAuthToken()` was called after login
|
||||
|
||||
### Can't see login page
|
||||
✅ **Fix:** Update app routing to start with auth check
|
||||
|
||||

|
||||
|

final authState = ref.watch(authProvider);
|
||||
final isLoading = authState.isLoading;
|
||||
final errorMessage = authState.errorMessage;
|
||||
|
||||
// Login
|
||||
await ref.read(authProvider.notifier).login(
|
||||
email: email,
|
||||
password: password,
|
||||
);
|
||||
|
||||
// Register
|
||||
await ref.read(authProvider.notifier).register(
|
||||
name: name,
|
||||
email: email,
|
||||
password: password,
|
||||
);
|

|
||||
### In your main.dart or app.dart:
|
||||
|
||||
```dart
|
||||
import 'package:flutter/material.dart';
|
||||
import 'package:flutter_riverpod/flutter_riverpod.dart';
|
||||
import 'features/auth/presentation/presentation.dart';
|
||||
|
||||
class MyApp extends StatelessWidget {
|
||||
@override
|
||||
Widget build(BuildContext context) {
|
||||
return ProviderScope(
|
||||
child: MaterialApp(
|
||||
theme: AppTheme.lightTheme(),
|
||||
darkTheme: AppTheme.darkTheme(),
|
||||
home: AuthWrapper(
|
||||
child: HomePage(), // Your main authenticated app
|
||||
),
|
||||
),
|
||||
);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### To show login page directly:
|
||||
|
||||
```dart
|
||||
Navigator.push(
|
||||
context,
|
||||
MaterialPageRoute(builder: (_) => LoginPage()),
|
||||
);
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Architecture Benefits
|
||||
|
||||
### 1. Clean Imports
|
||||
```dart
|
||||
// Before
|
||||
import 'package:retail/features/products/data/models/product_model.dart';
|
||||
import 'package:retail/features/products/domain/entities/product.dart';
|
||||
import 'package:retail/features/products/domain/repositories/product_repository.dart';
|
||||
|
||||
// After
|
||||
import 'package:retail/features/products/products.dart';
|
||||
```
|
||||
|
||||
### 2. Layer Separation
|
||||
- **Data Layer**: Models, data sources, repository implementations
|
||||
- **Domain Layer**: Entities, repository interfaces, use cases
|
||||
- **Presentation Layer**: Pages, widgets, providers
|
||||
|
||||
### 3. Dependency Rules
|
||||
- Presentation → Domain ← Data
|
||||
- Domain is independent (no dependencies on outer layers)
|
||||
- Data implements domain interfaces
|
||||
|
||||
### 4. Import Flexibility
|
||||
```dart
|
||||
// Import entire feature
|
||||
import 'package:retail/features/auth/auth.dart';
|
||||
|
||||
// Import specific layer
|
||||
import 'package:retail/features/auth/domain/domain.dart';
|
||||
|
||||
// Import specific component
|
||||
import 'package:retail/features/auth/domain/entities/entities.dart';
|
||||
```
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Feature-Level Import
|
||||
```dart
|
||||
import 'package:retail/features/products/products.dart';
|
||||
|
||||
// Access all layers: data, domain, presentation
|
||||
```
|
||||
|
||||
### Layer-Level Import
|
||||
```dart
|
||||
import 'package:retail/features/products/domain/domain.dart';
|
||||
|
||||
// Access: entities, repositories, use cases
|
||||
```
|
||||
|
||||
### Component-Level Import
|
||||
```dart
|
||||
import 'package:retail/features/products/domain/entities/entities.dart';
|
||||
|
||||
// Access: Product entity only
|
||||
```
|
||||
|
||||
### Core Utilities
|
||||
```dart
|
||||
import 'package:retail/core/core.dart';
|
||||
|
||||
// Access all core utilities: constants, network, theme, etc.
|
||||
```
|
||||
|
||||
### Specific Core Module
|
||||
```dart
|
||||
import 'package:retail/core/theme/theme.dart';
|
||||
|
||||
// Access: AppTheme, colors, typography
|
||||
```

## Guidelines
|
||||
|
||||
### DO's
|
||||
1. Import at the appropriate level (feature, layer, or component)
|
||||
2. Use barrel exports for cleaner code
|
||||
3. Respect layer boundaries (domain never imports data/presentation)
|
||||
4. Update barrel exports when adding/removing files
|
||||
|
||||
### DON'Ts
|
||||
1. Don't bypass barrel exports
|
||||
2. Don't violate layer dependencies
|
||||
3. Don't over-import (import only what you need)
|
||||
4. Don't import implementation details directly
|
||||
|
||||
## Maintenance
|
||||
|
||||
When making changes:
|
||||
|
||||
1. **Adding new file**: Update the appropriate barrel export
|
||||
2. **Removing file**: Remove from barrel export
|
||||
3. **Renaming file**: Update barrel export reference
|
||||
4. **New module**: Create new barrel exports following the pattern
|
||||
|
||||
## Documentation
|
||||
|
||||
Full documentation available at:
|
||||
- `/Users/ssg/project/retail/lib/EXPORTS_DOCUMENTATION.md`
|
||||
|
||||
## Key Features
|
||||
|
||||
- **52 barrel export files** covering all features and core modules
|
||||
- **Hierarchical organization** from top-level to component-level
|
||||
- **Layer isolation** enforcing clean architecture
|
||||
- **Flexible imports** at feature, layer, or component level
|
||||
- **Clear boundaries** between modules and layers
|
||||
- **Easy maintenance** with centralized exports
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. Update existing imports to use barrel exports
|
||||
2. Run `flutter analyze` to ensure no issues
|
||||
3. Test imports in different files
|
||||
4. Update team documentation
|
||||
5. Create import examples for common scenarios

# Riverpod Dependency Injection Migration
|
||||
|
||||
**Date**: October 10, 2025
|
||||
**Status**: ✅ **COMPLETE**
|
||||
|
||||
---
|
||||
|
||||
## Problem
|
||||
|
||||
The authentication system was trying to use GetIt for dependency injection, causing the following error:
|
||||
|
||||
```
|
||||
Bad state: GetIt: Object/factory with type AuthRepository is not registered inside GetIt.
|
||||
```
|
||||
|
||||
Additionally, there was a circular dependency error in the auth provider:
|
||||
|
||||
```
|
||||
Bad state: Tried to read the state of an uninitialized provider.
|
||||
This generally means that have a circular dependency, and your provider end-up depending on itself.
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Solution
|
||||
|
||||
Migrated from GetIt to **pure Riverpod dependency injection**. All dependencies are now managed through Riverpod providers.
|
||||
|
||||
---
|
||||
|
||||
## Changes Made
|
||||
|
||||
### 1. Updated Auth Provider (`lib/features/auth/presentation/providers/auth_provider.dart`)
|
||||
|
||||
**Before:**
|
||||
```dart
|
||||
import '../../../../core/di/injection_container.dart';
|
||||
|
||||
@riverpod
|
||||
AuthRepository authRepository(Ref ref) {
|
||||
return sl<AuthRepository>(); // Using GetIt
|
||||
}
|
||||
|
||||
@riverpod
|
||||
class Auth extends _$Auth {
|
||||
@override
|
||||
AuthState build() {
|
||||
_checkAuthStatus(); // Circular dependency - calling async in build
|
||||
return const AuthState();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**After:**
|
||||
```dart
|
||||
import '../../../../core/network/dio_client.dart';
|
||||
import '../../../../core/storage/secure_storage.dart';
|
||||
import '../../data/datasources/auth_remote_datasource.dart';
|
||||
import '../../data/repositories/auth_repository_impl.dart';
|

return DioClient();
|
||||
}
|
||||
|
||||
/// Provider for SecureStorage (singleton)
|
||||
@Riverpod(keepAlive: true)
|

SecureStorage secureStorage(Ref ref) {
|

final dioClient = ref.watch(dioClientProvider);
|
||||
|
||||
return AuthRepositoryImpl(
|
||||
remoteDataSource: remoteDataSource,
|
||||
secureStorage: secureStorage,
|
||||
dioClient: dioClient,
|
||||
);
|
||||
}
|
||||
|
||||
@riverpod
|
||||
class Auth extends _$Auth {
|
||||
@override
|
||||
AuthState build() {
|
||||
// Don't call async operations in build
|
||||
return const AuthState();
|
||||
}
|
||||
|
||||
/// Initialize auth state - call this on app start
|
||||
Future<void> initialize() async {
|
||||
// Auth initialization logic moved here
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Removed GetIt Setup (`lib/main.dart`)
|
||||
|
||||
**Before:**
|
||||
```dart
|
||||
import 'core/di/service_locator.dart';
|
||||
|
||||
void main() async {
|
||||
WidgetsFlutterBinding.ensureInitialized();
|
||||
await Hive.initFlutter();
|
||||
|
||||
// Setup dependency injection
|
||||
await setupServiceLocator(); // GetIt initialization
|
||||
|
||||
runApp(const ProviderScope(child: RetailApp()));
|
||||
}
|
||||
```
|
||||
|
||||
**After:**
|
||||
```dart
|
||||
void main() async {
|
||||
WidgetsFlutterBinding.ensureInitialized();
|
||||
await Hive.initFlutter();
|
||||
|
||||
// Run the app with Riverpod (no GetIt needed - using Riverpod for DI)
|
||||
runApp(const ProviderScope(child: RetailApp()));
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Initialize Auth State on App Start (`lib/app.dart`)
|
||||
|
||||
**Before:**
|
||||
```dart
|
||||
class RetailApp extends ConsumerWidget {
|
||||
const RetailApp({super.key});
|
||||
|
||||
@override
|
||||
Widget build(BuildContext context, WidgetRef ref) {
|
||||
return MaterialApp(/* ... */);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**After:**
|
||||
```dart
|
||||
class RetailApp extends ConsumerStatefulWidget {
|
||||
const RetailApp({super.key});
|
||||
|
||||
@override
|
||||
ConsumerState<RetailApp> createState() => _RetailAppState();
|
||||
}
|
||||
|
||||
class _RetailAppState extends ConsumerState<RetailApp> {
|
||||
@override
|
||||
void initState() {
|
||||
super.initState();
|
||||
// Initialize auth state on app start
|
||||
WidgetsBinding.instance.addPostFrameCallback((_) {
|
||||
ref.read(authProvider.notifier).initialize();
|
||||
});
|
||||
}
|
||||
|
||||
@override
|
||||
Widget build(BuildContext context) {
|
||||
return MaterialApp(/* ... */);
|
||||
}
|
||||
}
|
||||
```
|
||||

|
||||
|
||||
## Dependency Injection Architecture
|
||||
|
||||
### Provider Hierarchy
|
||||
|
||||
```
|
||||
DioClient (singleton)
|
||||
↓
|
||||
SecureStorage (singleton)
|
||||
↓
|
||||
AuthRemoteDataSource (uses DioClient)
|
||||
↓
|
||||
AuthRepository (uses AuthRemoteDataSource, SecureStorage, DioClient)
|
||||
↓
|
||||
Auth State Notifier (uses AuthRepository)
|
||||
```
|
||||
|
||||
### Provider Usage
|
||||
|
||||
```dart
|
||||
// Access DioClient
|
||||
final dioClient = ref.read(dioClientProvider);
|
||||
|
||||
// Access SecureStorage
|
||||
final secureStorage = ref.read(secureStorageProvider);
|
||||
|
||||
// Access AuthRepository
|
||||
final authRepository = ref.read(authRepositoryProvider);
|
||||
|
||||
// Access Auth State
|
||||
final authState = ref.watch(authProvider);
|
||||
|
||||
// Call Auth Methods
|
||||
await ref.read(authProvider.notifier).login(email: '...', password: '...');
|
||||
await ref.read(authProvider.notifier).logout();
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Benefits of Riverpod DI
|
||||
|
||||
1. **No Manual Registration**: Providers are automatically available
|
||||
2. **Type Safety**: Compile-time type checking
|
||||
3. **Dependency Graph**: Riverpod manages dependencies automatically
|
||||
4. **Testability**: Easy to override providers in tests
|
||||
5. **Code Generation**: Auto-generates provider code
|
||||
6. **No Circular Dependencies**: Proper lifecycle management
|
||||
7. **Singleton Management**: Use `keepAlive: true` for singletons
|
||||
|
||||
---
|
||||
|
||||
## GetIt Files (Now Unused)
|
||||
|
||||
These files are no longer needed but kept for reference:
|
||||
|
||||
- `lib/core/di/service_locator.dart` - Old GetIt setup
|
||||
- `lib/core/di/injection_container.dart` - Old GetIt container
|
||||
|
||||
You can safely delete these files if GetIt is not used anywhere else in the project.
|
||||
|
||||

|
||||
|
||||

|
||||
|
||||
- [x] Create Riverpod providers for DioClient
|
||||
- [x] Create Riverpod providers for SecureStorage
|
||||
- [x] Create Riverpod providers for AuthRemoteDataSource
|
||||
- [x] Create Riverpod providers for AuthRepository
|
||||
- [x] Remove GetIt references from auth_provider.dart
|
||||
- [x] Fix circular dependency in Auth.build()
|
||||
- [x] Remove GetIt setup from main.dart
|
||||
- [x] Initialize auth state in app.dart
|
||||
- [x] Regenerate code with build_runner
|
||||
- [x] Test compilation (0 errors)

||||
## Build Status
|
||||
|
||||
```
|
||||
✅ Errors: 0
|
||||
✅ Warnings: 61 (info-level only)
|
||||
✅ Build: SUCCESS
|
||||
✅ Code Generation: COMPLETE
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Testing the App
|
||||
|
||||
1. **Run the app**:
|
||||
```bash
|
||||
flutter run
|
||||
```
|
||||
|
||||
2. **Expected behavior**:
|
||||
- App starts and shows login page (if not authenticated)
|
||||
- Login with valid credentials
|
||||
- Token is saved and added to Dio headers automatically
|
||||
- Navigate to Settings to see user profile
|
||||
- Logout button works correctly
|
||||
- After logout, back to login page
|
||||
|
||||
---
|
||||
|
||||
## Key Takeaways
|
||||
|
||||
1. **Riverpod providers replace GetIt** for dependency injection
|
||||
2. **Use `keepAlive: true`** for singleton providers (DioClient, SecureStorage)
|
||||
3. **Never call async operations in `build()`** - use separate initialization methods
|
||||
4. **Initialize auth state in app.dart** using `addPostFrameCallback`
|
||||
5. **All dependencies are managed through providers** - no manual registration needed
|
||||
|
||||
---
|
||||
|
||||
## Next Steps (Optional)
|
||||
|
||||
If you want to further clean up:
|
||||
|
||||
1. Delete unused GetIt files:
|
||||
```bash
|
||||
rm lib/core/di/service_locator.dart
|
||||
rm lib/core/di/injection_container.dart
|
||||
```
|
||||
|
||||
2. Remove GetIt from dependencies in `pubspec.yaml`:
|
||||
```yaml
|
||||
# Remove this line:
|
||||
get_it: ^8.0.2
|
||||
```
|
||||
|
||||
3. Run `flutter pub get` to update dependencies
|
||||
|

|
||||
|
||||
**Status**: ✅ **MIGRATION COMPLETE - NO ERRORS**
|
||||
|

|
||||
import 'package:retail/features/auth/presentation/widgets/widgets.dart';
|
||||
```
|
||||
|
||||
### Core Utilities
|
||||
```dart
|
||||
// All core utilities
|
||||
import 'package:retail/core/core.dart';
|
||||
|
||||
// Specific core modules
|
||||
import 'package:retail/core/constants/constants.dart'; // All constants
|
||||
import 'package:retail/core/theme/theme.dart'; // Theme configuration

|
||||
import 'package:retail/core/storage/storage.dart'; // Secure storage
|
||||
import 'package:retail/core/widgets/widgets.dart'; // Core widgets
|
||||
```
|
||||
|
||||
### Shared Components
|
||||
```dart
|
||||
// Shared widgets and components
|
||||
import 'package:retail/shared/shared.dart';
|
||||
```
|
||||
|
||||
## Common Use Cases
|
||||
|
||||
### Building a Page
|
||||
```dart
|
||||
// In a page file, you typically need presentation layer
|
||||
import 'package:retail/features/products/presentation/presentation.dart';
|
||||
// This gives you: pages, widgets, providers
|
||||
```
|
||||
|
||||
### Implementing a Repository
|
||||
```dart
|
||||
// In repository implementation, import domain interfaces
|
||||
import 'package:retail/features/products/domain/domain.dart';
|
||||
// This gives you: entities, repository interfaces, use cases
|
||||
```
|
||||
|
||||
### Creating a Provider
|
||||
```dart
|
||||
// In a provider, import domain layer and other providers
|
||||
import 'package:retail/features/products/domain/domain.dart';
|
||||
import 'package:retail/features/products/presentation/providers/providers.dart';
|
||||
```
|
||||
|
||||
### Using Multiple Features
|
||||
```dart
|
||||
// When you need multiple features
|
||||
import 'package:retail/features/products/products.dart';
|
||||
import 'package:retail/features/categories/categories.dart';
|
||||
import 'package:retail/core/core.dart';
|
||||
```
|
||||
|
||||
## Layer Dependencies (Important!)
|
||||
|
||||
### Allowed Dependencies
|
||||
|
||||
```
|
||||
Presentation Layer:
|
||||
✅ Can import: domain, core, shared
|
||||
❌ Cannot import: data
|
||||
|
||||
Data Layer:
|
||||
✅ Can import: domain, core
|
||||
❌ Cannot import: presentation
|
||||
|
||||
Domain Layer:
|
||||
✅ Can import: core (only exceptions/interfaces)
|
||||
❌ Cannot import: data, presentation
|
||||
|
||||
Core:
|
||||
✅ Can import: nothing (self-contained)
|
||||
❌ Cannot import: features
|
||||
|
||||
Shared:
|
||||
✅ Can import: core
|
||||
❌ Cannot import: features (to avoid circular dependencies)
|
||||
```
|
||||
|
||||
### Example: Correct Dependencies
|
||||
|
||||
```dart
|
||||
// ✅ GOOD: Presentation imports domain
|
||||
// In: features/products/presentation/pages/products_page.dart
|
||||
import 'package:retail/features/products/domain/domain.dart';
|
||||
import 'package:retail/core/core.dart';
|
||||
|
||||
// ✅ GOOD: Data imports domain
|
||||
// In: features/products/data/repositories/product_repository_impl.dart
|
||||
import 'package:retail/features/products/domain/domain.dart';
|
||||
import 'package:retail/core/core.dart';
|
||||
|
||||
// ✅ GOOD: Domain is independent
|
||||
// In: features/products/domain/entities/product.dart
|
||||
import 'package:retail/core/errors/errors.dart'; // Only core exceptions
|
||||
|
||||
// ❌ BAD: Domain importing data or presentation
|
||||
// In: features/products/domain/usecases/get_products.dart
|
||||
import 'package:retail/features/products/data/data.dart'; // NEVER!
|
||||
import 'package:retail/features/products/presentation/presentation.dart'; // NEVER!
|
||||
```
|
||||
|
||||
## Import Decision Tree
|
||||
|
||||
```
|
||||
1. Do I need the entire feature?
|
||||
├─ Yes → import 'features/[feature]/[feature].dart'
|
||||
└─ No → Continue to 2
|
||||
|
||||
2. Do I need an entire layer?
|
||||
├─ Yes → import 'features/[feature]/[layer]/[layer].dart'
|
||||
└─ No → Continue to 3
|
||||
|
||||
3. Do I need specific components?
|
||||
└─ Yes → import 'features/[feature]/[layer]/[component]/[component].dart'
|
||||
|
||||
4. Is it a core utility?
|
||||
├─ All utilities → import 'core/core.dart'
|
||||
└─ Specific module → import 'core/[module]/[module].dart'
|
||||
|
||||
5. Is it a shared component?
|
||||
└─ Yes → import 'shared/shared.dart'
|
||||
```
|
||||
|
||||
## Migration from Direct Imports
|
||||
|
||||
### Before (Direct Imports - Fragile)
|
||||
```dart
|
||||
import 'package:retail/features/products/data/models/product_model.dart';
|
||||
import 'package:retail/features/products/data/datasources/product_local_datasource.dart';
|
||||
import 'package:retail/features/products/data/repositories/product_repository_impl.dart';
|
||||
import 'package:retail/features/products/domain/entities/product.dart';
|
||||
import 'package:retail/features/products/domain/repositories/product_repository.dart';
|
||||
import 'package:retail/features/products/presentation/pages/products_page.dart';
|
||||
import 'package:retail/features/products/presentation/widgets/product_card.dart';
|
||||
import 'package:retail/features/products/presentation/widgets/product_grid.dart';
|
||||
import 'package:retail/core/constants/api_constants.dart';
|
||||
import 'package:retail/core/theme/colors.dart';
|
||||
```
|
||||
|
||||
### After (Barrel Imports - Clean & Maintainable)
|
||||
```dart
|
||||
import 'package:retail/features/products/products.dart';
|
||||
import 'package:retail/core/core.dart';
|
||||
```
|
||||
|
||||
## Special Notes
|
||||
|
||||
### Products Providers
|
||||
The products feature has all providers consolidated in `products_provider.dart`:
|
||||
```dart
|
||||
// Import all product providers at once
|
||||
import 'package:retail/features/products/presentation/providers/providers.dart';
|
||||
|
||||
// This includes:
|
||||
// - productsProvider (list of products)
|
||||
// - searchQueryProvider (search state)
|
||||
// - filteredProductsProvider (filtered results)
|
||||
```
|
||||
|
||||
### Selected Category Provider
|
||||
The `selectedCategoryProvider` exists in multiple places:
|
||||
- In `categories_provider.dart` (for category management)
|
||||
- In `products/selected_category_provider.dart` (for product filtering)
|
||||
|
||||
Use the one from products when filtering products:
|
||||
```dart
|
||||
import 'package:retail/features/products/presentation/providers/providers.dart';
|
||||
// Use: selectedCategoryProvider for product filtering
|
||||
```
|
||||
|
||||
### Core Providers
|
||||
Core providers are in `core/providers/providers.dart`:
|
||||
```dart
|
||||
import 'package:retail/core/providers/providers.dart';
|
||||
// Includes: networkInfoProvider, syncStatusProvider
|
||||
```
|
||||
|
||||
## Tips for Best Practices
|
||||
|
||||
1. **Start broad, narrow down if needed**
|
||||
- Try feature-level import first
|
||||
- Move to layer-level if you only need one layer
|
||||
- Use component-level for very specific needs
|
||||
|
||||
2. **Avoid circular dependencies**
|
||||
- Domain never imports from data/presentation
|
||||
- Features don't import from each other (use shared instead)
|
||||
|
||||
3. **Use IDE autocomplete**
|
||||
- Type `import 'package:retail/` and let IDE suggest
|
||||
- Barrel exports will show up clearly
|
||||
|
||||
4. **Keep imports organized**
|
||||
```dart
|
||||
// 1. Dart/Flutter imports
|
||||
import 'package:flutter/material.dart';
|
||||
|
||||
// 2. Third-party packages
|
||||
import 'package:riverpod_annotation/riverpod_annotation.dart';
|
||||
|
||||
// 3. Project features
|
||||
import 'package:retail/features/products/products.dart';
|
||||
|
||||
// 4. Core utilities
|
||||
import 'package:retail/core/core.dart';
|
||||
|
||||
// 5. Shared components
|
||||
import 'package:retail/shared/shared.dart';
|
||||
```
|
||||
|
||||
5. **Update barrel exports when adding files**
|
||||
- Added new model? Update `models/models.dart`
|
||||
- Added new page? Update `pages/pages.dart`
|
||||
- New use case? Update `usecases/usecases.dart`
|
||||
|
||||

# Clean Architecture Export Files Documentation
|
||||
|
||||
This document describes all barrel export files created for the retail POS application, following clean architecture principles.
|
||||
|
||||
## Overview
|
||||
|
||||
Barrel export files provide a clean, organized way to import code by:
|
||||
- Simplifying imports across the codebase
|
||||
- Enforcing layer separation and boundaries
|
||||
- Making refactoring easier
|
||||
- Improving IDE autocomplete
|
||||
- Documenting module structure
|
||||
|
||||

|
||||
## Usage Examples
|
||||
|
||||
### 1. Importing Entire Features
|
||||
|
||||
```dart
|
||||
// Import complete auth feature (all layers)
|
||||
import 'package:retail/features/auth/auth.dart';
|
||||
|
||||
// Import complete products feature
|
||||
import 'package:retail/features/products/products.dart';
|
||||
|
||||
// Import all features at once
|
||||
import 'package:retail/features/features.dart';
|
||||
```
|
||||
|
||||
### 2. Importing Specific Layers
|
||||
|
||||
```dart
|
||||
// Import only auth domain layer (entities + repositories)
|
||||
import 'package:retail/features/auth/domain/domain.dart';
|
||||
|
||||
// Import only products presentation layer (pages + widgets + providers)
|
||||
import 'package:retail/features/products/presentation/presentation.dart';
|
||||
|
||||
// Import only cart data layer
|
||||
import 'package:retail/features/home/data/data.dart';
|
||||
```
|
||||
|
||||
### 3. Importing Specific Components
|
||||
|
||||
```dart
|
||||
// Import only auth entities
|
||||
import 'package:retail/features/auth/domain/entities/entities.dart';
|
||||
|
||||
// Import only product models
|
||||
import 'package:retail/features/products/data/models/models.dart';
|
||||
|
||||
// Import only category use cases
|
||||
import 'package:retail/features/categories/domain/usecases/usecases.dart';
|
||||
|
||||
// Import only product providers
|
||||
import 'package:retail/features/products/presentation/providers/providers.dart';
|
||||
```
|
||||
|
||||
### 4. Importing Core Utilities
|
||||
|
||||
```dart
|
||||
// Import all core utilities
|
||||
import 'package:retail/core/core.dart';
|
||||
|
||||
// Import only constants
|
||||
import 'package:retail/core/constants/constants.dart';
|
||||
|
||||
// Import only theme
|
||||
import 'package:retail/core/theme/theme.dart';
|
||||
|
||||
// Import only network utilities
|
||||
import 'package:retail/core/network/network.dart';
|
||||
|
||||
// Import only error handling
|
||||
import 'package:retail/core/errors/errors.dart';
|
||||
```
|
||||
|
||||
### 5. Importing Shared Components
|
||||
|
||||
```dart
|
||||
// Import shared widgets
|
||||
import 'package:retail/shared/shared.dart';
|
||||
```
|
||||
|
||||
## Clean Architecture Benefits
|
||||
|
||||
### Layer Isolation
|
||||
|
||||
The export structure enforces clean architecture principles:
|
||||
|
||||
```dart
|
||||
// ✅ GOOD: Domain layer importing from domain
|
||||
import 'package:retail/features/products/domain/domain.dart';
|
||||
|
||||
// ❌ BAD: Domain layer importing from data/presentation
|
||||
// Domain should never depend on outer layers
|
||||
import 'package:retail/features/products/data/data.dart';
|
||||
```
|
||||
|
||||
### Dependency Flow
|
||||
|
||||
Dependencies flow inward:
|
||||
- **Presentation** → Domain ← Data
|
||||
- **Data** → Domain (implements interfaces)
|
||||
- **Domain** → Independent (pure business logic)
|
||||
|
||||
```dart
|
||||
// In presentation layer - ✅ GOOD
|
||||
import 'package:retail/features/products/domain/domain.dart';
|
||||
|
||||
// In data layer - ✅ GOOD
|
||||
import 'package:retail/features/products/domain/domain.dart';
|
||||
|
||||
// In domain layer - ❌ NEVER
|
||||
// import 'package:retail/features/products/data/data.dart';
|
||||
// import 'package:retail/features/products/presentation/presentation.dart';
|
||||
```
|
||||
|
||||
## Feature Export Hierarchy
|
||||
|
||||
Each feature follows this export hierarchy:
|
||||
|
||||
```
|
||||
feature.dart # Top-level feature export
|
||||
├── data/data.dart # Data layer export
|
||||
│ ├── datasources/datasources.dart
|
||||
│ ├── models/models.dart
|
||||
│ └── repositories/ # Implementations (exported directly)
|
||||
├── domain/domain.dart # Domain layer export
|
||||
│ ├── entities/entities.dart
|
||||
│ ├── repositories/ # Interfaces (exported directly)
|
||||
│ └── usecases/usecases.dart
|
||||
└── presentation/presentation.dart # Presentation layer export
|
||||
├── pages/pages.dart
|
||||
├── providers/providers.dart
|
||||
└── widgets/widgets.dart
|
||||
```
|
||||
|
||||
## Import Guidelines
|
||||
|
||||
### DO's
|
||||
|
||||
1. **Import at the appropriate level**
|
||||
```dart
|
||||
// If you need the entire feature
|
||||
import 'package:retail/features/auth/auth.dart';
|
||||
|
||||
// If you only need domain entities
|
||||
import 'package:retail/features/auth/domain/entities/entities.dart';
|
||||
```
|
||||
|
||||
2. **Use barrel exports for cleaner code**
|
||||
```dart
|
||||
// ✅ Clean and maintainable
|
||||
import 'package:retail/features/products/presentation/presentation.dart';
|
||||
|
||||
// ❌ Messy and fragile
|
||||
import 'package:retail/features/products/presentation/pages/products_page.dart';
|
||||
import 'package:retail/features/products/presentation/widgets/product_card.dart';
|
||||
import 'package:retail/features/products/presentation/widgets/product_grid.dart';
|
||||
import 'package:retail/features/products/presentation/providers/products_provider.dart';
|
||||
```
|
||||
|
||||
3. **Respect layer boundaries**
|
||||
```dart
|
||||
// In a use case (domain layer)
|
||||
import 'package:retail/features/products/domain/domain.dart'; // ✅
|
||||
import 'package:retail/core/core.dart'; // ✅ (core is shared)
|
||||
```
|
||||
|
||||
### DON'Ts
|
||||
|
||||
1. **Don't bypass barrel exports**
|
||||
```dart
|
||||
// ❌ Bypasses barrel export
|
||||
import 'package:retail/features/products/data/models/product_model.dart';
|
||||
|
||||
// ✅ Use barrel export
|
||||
import 'package:retail/features/products/data/models/models.dart';
|
||||
```
|
||||
|
||||
2. **Don't violate layer dependencies**
|
||||
```dart
|
||||
// In domain layer
|
||||
// ❌ Domain depends on outer layers
|
||||
import 'package:retail/features/products/data/data.dart';
|
||||
import 'package:retail/features/products/presentation/presentation.dart';
|
||||
```
|
||||
|
||||
3. **Don't import entire feature when you need one layer**
|
||||
```dart
|
||||
// ❌ Over-importing
|
||||
import 'package:retail/features/products/products.dart'; // Imports all layers
|
||||
// When you only need:
|
||||
import 'package:retail/features/products/domain/entities/entities.dart';
|
||||
```
|
||||
|
||||
## Benefits Summary
|
||||
|
||||
### 1. Clean Imports
|
||||
Before:
|
||||
```dart
|
||||
import 'package:retail/features/products/data/models/product_model.dart';
|
||||
import 'package:retail/features/products/domain/entities/product.dart';
|
||||
import 'package:retail/features/products/domain/repositories/product_repository.dart';
|
||||
import 'package:retail/features/products/presentation/pages/products_page.dart';
|
||||
import 'package:retail/features/products/presentation/widgets/product_card.dart';
|
||||
import 'package:retail/features/products/presentation/widgets/product_grid.dart';
|
||||
```
|
||||
|
||||
After:
|
||||
```dart
|
||||
import 'package:retail/features/products/products.dart';
|
||||
```
|
||||
|
||||
### 2. Layer Isolation
|
||||
- Domain layer never imports from data/presentation
|
||||
- Each layer has clear boundaries
|
||||
- Enforces dependency inversion
|
||||
|
||||
### 3. Easy Refactoring
|
||||
- Change internal structure without breaking imports
|
||||
- Move files within a layer without updating imports
|
||||
- Rename files without affecting external code
|
||||
|
||||
### 4. Better IDE Support
|
||||
- Autocomplete shows only exported items
|
||||
- Easier to navigate code structure
|
||||
- Clear module boundaries
|
||||
|
||||
### 5. Documentation
|
||||
- Export files serve as documentation
|
||||
- Shows what's public vs private
|
||||
- Makes architecture explicit
|
||||
|
||||
## Migration Guide
|
||||
|
||||
If you have existing imports, migrate them gradually:
|
||||
|
||||
### Step 1: Update feature-level imports
|
||||
```dart
|
||||
// Old
|
||||
import 'package:retail/features/products/presentation/pages/products_page.dart';
|
||||
|
||||
// New
|
||||
import 'package:retail/features/products/presentation/pages/pages.dart';
|
||||
```
|
||||
|
||||
### Step 2: Consolidate layer imports
|
||||
```dart
|
||||
// Old
|
||||
import 'package:retail/features/products/presentation/pages/pages.dart';
|
||||
import 'package:retail/features/products/presentation/widgets/widgets.dart';
|
||||
import 'package:retail/features/products/presentation/providers/providers.dart';
|
||||
|
||||
// New
|
||||
import 'package:retail/features/products/presentation/presentation.dart';
|
||||
```
|
||||
|
||||
### Step 3: Use top-level feature import when appropriate
|
||||
```dart
|
||||
// If you need multiple layers
|
||||
import 'package:retail/features/products/products.dart';
|
||||
```
|
||||
|
||||

## Maintenance
|
||||
|
||||
When adding new files to the project:
|
||||
|
||||
1. **New file in existing module**: Update the appropriate barrel export
|
||||
2. **New module**: Create new barrel exports following the pattern
|
||||
3. **Removing files**: Update barrel exports to remove deleted exports
|
||||
4. **Renaming files**: Update barrel exports to reflect new names
|
||||
|
||||
## Support
|
||||
|
||||
For questions or issues with the export structure, refer to:
|
||||
- This documentation
|
||||
- Clean Architecture principles
|
||||
- Feature-first organization patterns

|
||||
}
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### 1. Setup (Already configured in injection_container.dart)
|
||||
|
||||
The authentication system is registered in the dependency injection container:
|
||||
|
||||
```dart
|
||||
// In lib/core/di/injection_container.dart
|
||||
Future<void> initDependencies() async {
|
||||
// Secure Storage
|
||||
sl.registerLazySingleton<SecureStorage>(() => SecureStorage());
|
||||
|
||||
// Auth Remote Data Source
|
||||
sl.registerLazySingleton<AuthRemoteDataSource>(
|
||||
() => AuthRemoteDataSourceImpl(dioClient: sl()),
|
||||
);
|
||||
|
||||
// Auth Repository
|
||||
sl.registerLazySingleton<AuthRepository>(
|
||||
() => AuthRepositoryImpl(
|
||||
remoteDataSource: sl(),
|
||||
secureStorage: sl(),
|
||||
dioClient: sl(),
|
||||
),
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Login Flow
|
||||
|
||||
```dart
|
||||
import 'package:flutter_riverpod/flutter_riverpod.dart';
|
||||
import 'package:retail/features/auth/presentation/providers/auth_provider.dart';
|
||||
|
||||
// In a widget
|
||||
class MyWidget extends ConsumerWidget {
|
||||
@override
|
||||
Widget build(BuildContext context, WidgetRef ref) {
|
||||
return ElevatedButton(
|
||||
onPressed: () async {
|
||||
final success = await ref.read(authProvider.notifier).login(
|
||||
email: 'user@example.com',
|
||||
password: 'Password123!',
|
||||
);
|
||||
|
||||
if (success) {
|
||||
// Navigate to home
|
||||
} else {
|
||||
// Show error
|
||||
final error = ref.read(authProvider).errorMessage;
|
||||
print('Login failed: $error');
|
||||
}
|
||||
},
|
||||
child: Text('Login'),
|
||||
);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Check Authentication Status
|
||||
|
||||
```dart
|
||||
// Check if user is authenticated
|
||||
final isAuthenticated = ref.watch(isAuthenticatedProvider);
|
||||
|
||||
// Get current user
|
||||
final user = ref.watch(currentUserProvider);
|
||||
|
||||
if (user != null) {
|
||||
print('Welcome ${user.name}!');
|
||||
print('Roles: ${user.roles}');
|
||||
print('Is Admin: ${user.isAdmin}');
|
||||
}
|
||||
```
|
||||
|
||||
### 4. Logout
|
||||
|
||||
```dart
|
||||
await ref.read(authProvider.notifier).logout();
|
||||
```
|
||||
|
||||
### 5. Register New User
|
||||
|
||||
```dart
|
||||
final success = await ref.read(authProvider.notifier).register(
|
||||
name: 'John Doe',
|
||||
email: 'john@example.com',
|
||||
password: 'Password123!',
|
||||
roles: ['user'], // Optional, defaults to ['user']
|
||||
);
|
||||
```
|
||||
|
||||
### 6. Refresh Token
|
||||
|
||||
```dart
|
||||
final success = await ref.read(authProvider.notifier).refreshToken();
|
||||
|
||||
if (!success) {
|
||||
// Token refresh failed, user logged out automatically
|
||||
}
|
||||
```
|
||||
|
||||
## Bearer Token Injection
|
||||
|
||||
The authentication system automatically injects the JWT bearer token into all API requests:
|
||||
|
||||
### How it Works
|
||||
|
||||
1. **On Login/Register**: Token is saved to secure storage and set in DioClient
|
||||
2. **Automatic Injection**: DioClient interceptor adds `Authorization: Bearer {token}` header to all requests
|
||||
3. **On Logout**: Token is cleared from secure storage and DioClient
|
||||
4. **On App Start**: Token is loaded from secure storage and set in DioClient if valid
|
||||
|
||||
### Implementation Details
|
||||
|
||||
```dart
|
||||
// In lib/core/network/dio_client.dart
|
||||
class DioClient {
|
||||
String? _authToken;
|
||||
|
||||
DioClient() {
|
||||
_dio.interceptors.add(
|
||||
InterceptorsWrapper(
|
||||
onRequest: (options, handler) {
|
||||
if (_authToken != null) {
|
||||
options.headers['Authorization'] = 'Bearer $_authToken';
|
||||
}
|
||||
return handler.next(options);
|
||||
},
|
||||
),
|
||||
);
|
||||
}
|
||||
|
||||
void setAuthToken(String token) {
|
||||
_authToken = token;
|
||||
}
|
||||
|
||||
void clearAuthToken() {
|
||||
_authToken = null;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Manual Token Management (Advanced)
|
||||
|
||||
If you need to manually manage tokens:
|
||||
|
||||
```dart
|
||||
// Get token from storage
|
||||
final token = await sl<SecureStorage>().getAccessToken();
|
||||
|
||||
// Set token in DioClient
|
||||
sl<DioClient>().setAuthToken(token!);
|
||||
|
||||
// Clear token
|
||||
sl<DioClient>().clearAuthToken();
|
||||
await sl<SecureStorage>().deleteAllTokens();
|
||||
```
|
||||
|
||||
## Error Handling
|
||||
|
||||
The authentication system handles various error scenarios:
|
||||
|
||||
### Error Types
|
||||
|
||||
1. **InvalidCredentialsFailure**: Wrong email or password
|
||||
2. **ConflictFailure**: Email already exists (registration)
|
||||
3. **UnauthorizedFailure**: Invalid or expired token
|
||||
4. **NetworkFailure**: No internet connection
|
||||
5. **ServerFailure**: Server errors (500, 503, etc.)
|
||||
6. **ValidationFailure**: Invalid input data
|
||||
|
||||
### Error Handling Example
|
||||
|
||||
```dart
|
||||
final success = await ref.read(authProvider.notifier).login(
|
||||
email: email,
|
||||
password: password,
|
||||
);
|
||||
|
||||
if (!success) {
|
||||
final error = ref.read(authProvider).errorMessage;
|
||||
|
||||
// Show user-friendly error message
|
||||
ScaffoldMessenger.of(context).showSnackBar(
|
||||
SnackBar(
|
||||
content: Text(error ?? 'Login failed'),
|
||||
backgroundColor: Colors.red,
|
||||
),
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## Secure Storage
|
||||
|
||||
JWT tokens are stored securely using `flutter_secure_storage`:
|
||||
|
||||
- **iOS**: Keychain
|
||||
- **Android**: EncryptedSharedPreferences
|
||||
- **Web**: Web Crypto API
|
||||
- **Desktop**: Platform-specific secure storage
|
||||
|
||||
```dart
|
||||
// Access secure storage
|
||||
final secureStorage = sl<SecureStorage>();
|
||||
|
||||
// Save token
|
||||
await secureStorage.saveAccessToken(token);
|
||||
|
||||
// Get token
|
||||
final token = await secureStorage.getAccessToken();
|
||||
|
||||
// Check if token exists
|
||||
final hasToken = await secureStorage.hasAccessToken();
|
||||
|
||||
// Delete token
|
||||
await secureStorage.deleteAllTokens();
|
||||
```
|
||||
|
||||
## State Management
|
||||
|
||||
The authentication state is managed using Riverpod 3.0:
|
||||
|
||||
### AuthState
|
||||
|
||||
```dart
|
||||
class AuthState {
|
||||
final User? user; // Current authenticated user
|
||||
final bool isAuthenticated; // Authentication status
|
||||
final bool isLoading; // Loading state
|
||||
final String? errorMessage; // Error message (if any)
|
||||
}
|
||||
```
|
||||
|
||||
### Watching Auth State
|
||||
|
||||
```dart
|
||||
// Watch entire auth state
|
||||
final authState = ref.watch(authProvider);
|
||||
|
||||
// Access specific properties
|
||||
final user = authState.user;
|
||||
final isLoading = authState.isLoading;
|
||||
final error = authState.errorMessage;
|
||||
|
||||
// Or use convenience providers
|
||||
final isAuthenticated = ref.watch(isAuthenticatedProvider);
|
||||
final currentUser = ref.watch(currentUserProvider);
|
||||
```
|
||||
|
||||
## Protected Routes
|
||||
|
||||
Implement route guards to protect authenticated routes:
|
||||
|
||||
```dart
|
||||
class AuthGuard extends ConsumerWidget {
|
||||
final Widget child;
|
||||
|
||||
const AuthGuard({required this.child});
|
||||
|
||||
@override
|
||||
Widget build(BuildContext context, WidgetRef ref) {
|
||||
final isAuthenticated = ref.watch(isAuthenticatedProvider);
|
||||
final isLoading = ref.watch(authProvider.select((s) => s.isLoading));
|
||||
|
||||
if (isLoading) {
|
||||
return const Scaffold(
|
||||
body: Center(child: CircularProgressIndicator()),
|
||||
);
|
||||
}
|
||||
|
||||
if (!isAuthenticated) {
|
||||
return const LoginPage();
|
||||
}
|
||||
|
||||
return child;
|
||||
}
|
||||
}
|
||||
|
||||
// Usage
|
||||
MaterialApp(
|
||||
home: AuthGuard(
|
||||
child: HomePage(),
|
||||
),
|
||||
);
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
### Unit Tests
|
||||
|
||||
```dart
|
||||
test('login should return success with valid credentials', () async {
|
||||
// Arrange
|
||||
final repository = MockAuthRepository();
|
||||
when(repository.login(email: any, password: any))
|
||||
.thenAnswer((_) async => Right(mockAuthResponse));
|
||||
|
||||
// Act
|
||||
final result = await repository.login(
|
||||
email: 'test@example.com',
|
||||
password: 'Password123!',
|
||||
);
|
||||
|
||||
// Assert
|
||||
expect(result.isRight(), true);
|
||||
});
|
||||
```
|
||||
|
||||
### Integration Tests
|
||||
|
||||
Test the complete authentication flow from UI to API.
|
||||
|
||||
## Code Generation
|
||||
|
||||
Run code generation for Riverpod providers:
|
||||
|
||||
```bash
|
||||
# Generate auth_provider.g.dart
|
||||
flutter pub run build_runner build --delete-conflicting-outputs
|
||||
|
||||
# Watch for changes
|
||||
flutter pub run build_runner watch
|
||||
```
|
||||
|
||||
## Production Considerations
|
||||
|
||||
1. **HTTPS**: Always use HTTPS in production
|
||||
2. **Token Expiry**: Implement automatic token refresh on 401 errors
|
||||
3. **Biometric Auth**: Add fingerprint/face ID support
|
||||
4. **Password Strength**: Enforce strong password requirements
|
||||
5. **Rate Limiting**: Handle rate limiting (429 errors)
|
||||
6. **Secure Storage**: Tokens are already stored securely
|
||||
7. **Session Management**: Clear tokens on app uninstall
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
- [ ] Biometric authentication (fingerprint, face ID)
|
||||
- [ ] Remember me functionality
|
||||
- [ ] Password reset flow
|
||||
- [ ] Email verification
|
||||
- [ ] Social login (Google, Apple, Facebook)
|
||||
- [ ] Multi-factor authentication (MFA)
|
||||
- [ ] Session timeout warning
|
||||
- [ ] Device management
