Code Generation ### Build Runner Runs code generators. ```yaml dev_dependencies: build_runner: ^2.4.0 ``` **Usage:** ```bash flutter pub run build_runner build --delete-conflicting-outputs ``` ### Freezed Immutable data classes with code generation. ```yaml dependencies: freezed_annotation: ^2.4.0 dev_dependencies: freezed: ^2.4.0 json_serializable: ^6.7.0 ``` **Example:** ```dart @freezed class User with _$User { const factory User({ required String id, required String name, }) = _User; factory User.fromJson(Map json) => _$UserFromJson(json); } ``` --- ## 8. Testing ### Mockito Mocking library for unit tests. ```yaml dev_dependencies: mockito: ^5.4.0 ``` **Usage:** ```dart @GenerateMocks([UserRepository]) void main() { final mockRepo = MockUserRepository(); when(mockRepo.getUser('123')).thenAnswer((_) async => User(id: '123')); final user = await mockRepo.getUser('123'); expect(user.id, '123'); } ``` ### Integration Test Test complete flows. ```bash flutter test integration_test/app_test.dart ``` --- ## 9. CI/CD Tools ### Codemagic **Best for:** Flutter-specific CI/CD **Features:** - Pre-configured Flutter builds - iOS/Android deployment - Free tier available ### GitHub Actions **Best for:** Open source projects **Example workflow:** ```yaml name: Flutter CI on: [push, pull_request] jobs: build: runs-on: ubuntu-latest steps: - uses: actions/checkout@v2 - uses: subosito/flutter-action@v2 - run: flutter pub get - run: flutter analyze - run: flutter test - run: flutter build apk ``` ### Fastlane **Best for:** Automating deployments ```bash fastlane ios beta # Deploy to TestFlight fastlane android beta # Deploy to Play Store ``` --- ## 10. Crash Reporting & Analytics ### Firebase Crashlytics Real-time crash reporting. ```yaml dependencies: firebase_crashlytics: ^3.4.0 ``` **Usage:** ```dart FirebaseCrashlytics.instance.recordError(error, stackTrace); ``` ### Sentry Error tracking platform. ```yaml dependencies: sentry_flutter: ^7.10.0 ``` --- ## 11. Dependency Injection ### Get It Service locator for DI. ```yaml dependencies: get_it: ^7.6.0 ``` **Usage:** ```dart final getIt = GetIt.instance; getIt.registerSingleton(ApiClient()); final apiClient = getIt(); ``` ### Injectable Code-generated DI with annotations. ```yaml dependencies: injectable: ^2.3.0 get_it: ^7.6.0 dev_dependencies: injectable_generator: ^2.4.0 ``` --- ## 12. Routing ### GoRouter Official routing package. ```yaml dependencies: go_router: ^13.0.0 ``` **Features:** - Declarative routing - Deep linking - Web support - Guards ### AutoRoute Type-safe routing with code generation. ```yaml dependencies: auto_route: ^7.8.0 dev_dependencies: auto_route_generator: ^7.3.0 ``` --- ## 13.
