App can navigate to login screen + +```dart +final apiClient = ApiClient( + secureStorage, + onUnauthorized: () { + // This callback is triggered on 401 errors + context.go('/login'); // Navigate to login + }, +); +``` + +### 3. Comprehensive Logging + +All requests, responses, and errors are logged with sensitive data redacted: + +``` +REQUEST[GET] => https://api.example.com/warehouses +Headers: {Authorization: ***REDACTED***, Content-Type: application/json} + +RESPONSE[200] => https://api.example.com/warehouses +Data: {...} + +ERROR[401] => https://api.example.com/products +401 Unauthorized - Clearing tokens and triggering logout +``` + +### 4.

If not authenticated → Redirects to `/login` +4. If authenticated but missing params → Redirects to `/warehouses` + +## Troubleshooting + +### Problem: Stuck on login page after successful login +**Solution**: Check if token is being saved to SecureStorage +```dart +// In LoginUseCase +await secureStorage.saveAccessToken(user.accessToken); +``` + +### Problem: Redirect loop between login and warehouses +**Solution**: Verify `isAuthenticated()` logic +```dart +// Should return true only if token exists +Future isAuthenticated() async { + final token = await getAccessToken(); + return token != null && token.isNotEmpty; +} +``` + +### Problem: Navigation parameters are null +**Solution**: Use extension methods with correct types +```dart +// Correct +context.goToOperations(warehouse); + +// Wrong - may lose type information +context.go('/operations', extra: warehouse); +``` + +### Problem: Router doesn't react to auth changes +**Solution**: Verify GoRouterRefreshStream is listening +```dart +GoRouterRefreshStream(this.ref) { + ref.listen( + authProvider, // Must be the correct provider + (_, __) => notifyListeners(), + ); +} +``` + +## Next Steps + +1. **Implement Warehouse Provider** + - Create warehouse state management + - Load warehouses from API + - Integrate with warehouse selection page + +2. **Implement Products Provider** + - Create products state management + - Load products based on warehouse and operation + - Integrate with products page + +3. **Add Loading States** + - Show loading indicators during navigation + - Handle network errors gracefully + +4. **Add Analytics** + - Track navigation events + - Monitor authentication flow + +## Related Documentation + +- **Router Details**: `/lib/core/router/README.md` +- **Auth Setup**: `/lib/features/auth/di/auth_dependency_injection.dart` +- **SecureStorage**: `/lib/core/storage/secure_storage.dart` +- **Examples**: `/lib/features/warehouse/presentation/pages/warehouse_selection_page_example.dart` + +## Summary + +The complete GoRouter setup provides: +- Authentication-based navigation with auto-redirect +- Type-safe parameter passing +- Reactive updates on auth state changes +- Proper error handling and validation +- Easy-to-use extension methods +- Integration with existing SecureStorage and Riverpod + +The app flow is: **Login → Warehouses → Operations → Products** + +All protected routes automatically redirect to login if user is not authenticated. diff --git

Core Layer (Infrastructure) + +**Purpose**: Provide foundational services that all features depend on + +**Providers**: +- `secureStorageProvider` - Manages encrypted storage +- `apiClientProvider` - HTTP client with auth interceptors + +**Characteristics**: +- Singleton instances +- No business logic +- Pure infrastructure +- Used by all features + +**Example**: +```dart +final secureStorageProvider = Provider((ref) { + return SecureStorage(); +}); + +final apiClientProvider = Provider((ref) { + final secureStorage = ref.watch(secureStorageProvider); + return ApiClient(secureStorage); +}); +``` + +### 2.

+``` + +## Best Practices + +1. **Always use ApiResponse**: Parse all responses using the `ApiResponse` wrapper +2. **Handle errors gracefully**: Catch specific exception types for better error handling +3. **Use endpoints constants**: Define all endpoints in `api_endpoints.dart` +4. **Don't expose Dio**: Use the provided methods (get, post, put, delete) instead of accessing `dio` directly +5. **Test connection**: Use `testConnection()` before critical operations +6. **Log appropriately**: The client logs automatically, but you can add app-level logs too + +## Testing + +Mock the API client in tests: + +```dart +class MockApiClient extends Mock implements ApiClient {} + +void main() { + late MockApiClient mockApiClient; + + setUp(() { + mockApiClient = MockApiClient(); + }); + + test('should get warehouses', () async { + // Arrange + when(mockApiClient.get(any)) + .thenAnswer((_) async => Response( + data: {'Value': [], 'IsSuccess': true}, + statusCode: 200, + requestOptions: RequestOptions(path: '/warehouses'), + ));
