Use GoRouter or auto_route for navigation and deep linking. + 2. Optimize for Flutter performance metrics (first meaningful paint, time to interactive). + 3. Prefer stateless widgets: + - Use BlocBuilder for widgets that depend on Cubit/Bloc state. + - Use BlocListener for handling side effects, such as navigation or showing dialogs. + + UI and Styling + - Use Flutter's built-in widgets and create custom widgets. + - Implement responsive design using LayoutBuilder or MediaQuery. + - Use themes for consistent styling across the app. + - Use Theme.of(context).textTheme.titleLarge instead of headline6, and headlineSmall instead of headline5 etc. + + Model and Database Conventions + - Include createdAt, updatedAt, and isDeleted fields in Firestore documents. + - Use @JsonSerializable(fieldRename: FieldRename.snake) for models. + - Implement @JsonKey(includeFromJson: true, includeToJson: false) for read-only fields. + + Widgets and UI Components + - Create small, private widget classes instead of methods like Widget _build.... + - Implement RefreshIndicator for pull-to-refresh functionality. + - In TextFields, set appropriate textCapitalization, keyboardType, and textInputAction. + - Always include an errorBuilder when using Image.network. + + Miscellaneous + - Use log instead of print for debugging. + - Use BlocObserver for monitoring state transitions during debugging. + - Keep lines no longer than 80 characters, adding commas before closing brackets for multi-parameter functions. + - Use @JsonValue(int) for enums that go to the database. + + Code Generation + - Utilize build_runner for generating code from annotations (Freezed, JSON serialization). + - Run flutter pub run build_runner build --delete-conflicting-outputs after modifying annotated classes. + + Documentation + - Document complex logic and non-obvious code decisions. + - Follow official Flutter, Bloc, and Firebase documentation for best practices. + + Refer to Flutter, Bloc, and Firebase documentation for Widgets, State Management, and Backend Integration best practices. + `, + }, ];
