BaseCubitPage<C extends MainCubit<MainBlocState>> class abstract

A base class for all stateless widget pages in the application that use a Cubit.

This class extends BasePageStatelessDelegate and provides a foundation for creating stateless widget pages that are associated with a specific Cubit.

Type Parameters:

  • C: The type of Cubit this page will use. Must extend MainCubit.

Features:

  • Built-in loading state management via CommonBloc
  • Automatic dependency injection using GetIt
  • Navigation support via AppNavigator
  • Built-in loading overlay with timeout
  • Direct state management without events

The class manages:

  • Loading indicator display and hiding
  • Common bloc integration
  • Navigation setup
  • Dependency injection

Usage example:

class MyCounterPage extends BaseCubitPage<CounterCubit> {
  const MyCounterPage({super.key});

  @override
  Widget buildPage(BuildContext context) {
    return buildLoadingOverlay(
      child: Scaffold(
        appBar: AppBar(title: const Text('Counter')),
        body: BlocBuilder<CounterCubit, CounterState>(
          builder: (context, state) {
            return Text('${state.count}');
          },
        ),
        floatingActionButton: Column(
          mainAxisAlignment: MainAxisAlignment.end,
          children: [
            FloatingActionButton(
              onPressed: () => cubit.increment(), // Direct method call
              child: const Icon(Icons.add),
            ),
            const SizedBox(height: 16),
            FloatingActionButton(
              onPressed: () => cubit.decrement(), // Direct method call
              child: const Icon(Icons.remove),
            ),
          ],
        ),
      ),
    );
  }
}

Compared to BaseBlocPage, this class:

  1. Uses direct method calls instead of events
  2. Generally requires less boilerplate code
  3. Is better suited for simple state changes
  4. Still provides all the same infrastructure for loading states and error handling
