Mobile Coding Standards

Widget Organization​

  • Screens in lib/screens/
  • Reusable widgets in lib/widgets/
  • Keep widgets small and focused

State Management​

Use Provider for app state:

// In provider
class UserProvider extends ChangeNotifier {
  User? _user;
  User? get user => _user;
  
  Future<void> login(String email, String password) async {
    _user = await AuthService.login(email, password);
    notifyListeners();
  }
}

// In widget
Consumer<UserProvider>(
  builder: (context, userProvider, child) {
    return Text(userProvider.user?.name ?? 'Guest');
  },
)

Error Handling​

try {
  await apiService.doSomething();
} catch (e) {
  ScaffoldMessenger.of(context).showSnackBar(
    SnackBar(content: Text('Error: $e')),
  );
}
