Define routes, parameters, and navigation guards:
// lib/presentation/routes/app_routes.dart
class AppRoutes {
static const login = '/login';
static const home = '/home';
static const profile = '/profile/:id'; // With parameter
static const settings = '/settings';
}
// lib/presentation/routes/app_pages.dart
class AppPages {
static final pages = [
GetPage(
name: AppRoutes.login,
page: () => LoginPage(),
binding: AuthBinding(),
),
GetPage(
name: AppRoutes.home,
page: () => HomePage(),
binding: HomeBinding(),
middlewares: [AuthMiddleware()], // Navigation guard
),
GetPage(
name: AppRoutes.profile,
page: () => ProfilePage(),
binding: ProfileBinding(),
),
];
}
Navigation Considerations:
Define translation keys and locale management:
// lib/core/i18n/app_translations.dart
class AppTranslations extends Translations {
@override
Map<String, Map<String, String>> get keys => {
'en_US': {
'login.title': 'Login',
'login.email': 'Email',
'login.password': 'Password',
'login.submit': 'Sign In',
'login.error.invalid_credentials': 'Invalid email or password',
},
'ar_SA': {
'login.title': 'تسجيل الدخول',
'login.email': 'البريد الإلكتروني',
'login.password': 'كلمة المرور',
'login.submit': 'تسجيل الدخول',
'login.error.invalid_credentials': 'البريد الإلكتروني أو كلمة المرور غير صحيحة',
},
};
}
// Usage in widgets
Text('login.title'.tr) // Automatically uses current locale
Translation Key Structure:
[screen].[widget].[label] - For UI text[screen].error.[error_code] - For error messagescommon.[label] - For shared text (Save, Cancel, etc.)validation.[rule] - For validation messagesLocale Management:
Optimize for smooth 60 FPS experience:
Widget Optimization:
// Use const constructors where possible
const Text('Static text')
const Icon(Icons.home)
// Proper key usage for list items
ListView.builder(
itemBuilder: (context, index) {
return ListTile(
key: ValueKey(items[index].id), // Stable key
title: Text(items[index].name),
);
},
)
// Minimize rebuild scope with Obx
Column(
children: [
Obx(() => Text(controller.title.value)), // Only text rebuilds
ExpensiveWidget(), // Doesn't rebuild
],
)
Lazy Loading Strategies:

Code Splitting:
Ensure WCAG 2.2 Level AA compliance:
Semantic Labels:
// All interactive widgets need labels
Semantics(
label: 'Login button',
hint: 'Double tap to sign in',
button: true,
enabled: true,
child: ElevatedButton(
onPressed: _login,
child: Text('Login'),
),
)
// Text fields with clear descriptions
TextField(
decoration: InputDecoration(
labelText: 'Email',
semanticsLabel: 'Email address input field',
),
)
Keyboard Navigation:
Screen Reader Support:
Touch Target Sizing:
Color Contrast:
Unit Tests (Domain & Data layers):
// Domain: Test use cases with mocked repositories
test('login user returns user on success', () async {
when(() => mockRepository.login(email, password))
.thenAnswer((_) async => Right(user));
final result = await loginUseCase(email, password);
expect(result, Right(user));
verify(() => mockRepository.login(email, password)).called(1);
});
// Data: Test repositories with mocked data sources
test('repository returns user from remote when successful', () async {
when(() => mockRemoteDataSource.login(email, password))
.thenAnswer((_) async => userModel);
final result = await repository.login(email, password);
expect(result, Right(user));
});
Widget Tests (Presentation layer):
testWidgets('login page shows error on invalid credentials', (tester) async {
await tester.pumpWidget(GetMaterialApp(home: LoginPage()));
await tester.enterText(find.byType(TextField).first, 'invalid@email.com');
await tester.enterText(find.byType(TextField).last, 'wrongpass');
await tester.tap(find.byType(ElevatedButton));
await tester.pumpAndSettle();
expect(find.text('Invalid email or password'), findsOneWidget);
});
Integration Tests:
testWidgets('full login flow works end-to-end', (tester) async {
await tester.pumpWidget(MyApp());
// Navigate to login
await tester.tap(find.text('Login'));
await tester.pumpAndSettle();
// Enter credentials
await tester.enterText(find.byType(TextField).first, 'user@example.com');
await tester.enterText(find.byType(TextField).last, 'password123');
// Submit
await tester.tap(find.text('Sign In'));
await tester.pumpAndSettle();
// Verify navigation to home
expect(find.text('Welcome'), findsOneWidget);
});
Test Coverage Goals:
Define GetX bindings for each feature:
class AuthBinding extends Bindings {
@override
void dependencies() {
// Data sources
Get.lazyPut<UserRemoteDataSource>(
() => UserRemoteDataSourceImpl(http: Get.find()),
);
Get.lazyPut<UserLocalDataSource>(
() => UserLocalDataSourceImpl(storage: Get.find()),
);
// Repositories
Get.lazyPut<UserRepository>(
() => UserRepositoryImpl(
remoteDataSource: Get.find(),
localDataSource: Get.find(),
),
);
// Use cases
Get.lazyPut(() => LoginUser(repository: Get.find()));
Get.lazyPut(() => LogoutUser(repository: Get.find()));
// Controller
Get.lazyPut(
() => AuthController(
loginUser: Get.find(),
logoutUser: Get.find(),
),
);
}
}
Dependency Management:
lazyPut for most dependencies (created when first requested)put for singletons needed immediatelyputAsync for async initializationDefine transitions and animations:
