BaseBlocPage<B extends MainBloc<MainBlocEvent, MainBlocState>> class abstract

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

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

Type Parameters:

  • B: The type of Bloc this page will use. Must extend MainBloc.

Features:

  • Built-in loading state management via CommonBloc
  • Automatic dependency injection using GetIt
  • Navigation support via AppNavigator
  • Built-in loading overlay with timeout
  • Automatic lifecycle management

The class manages:

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

Usage example:

class MyHomePage extends BaseBlocPage<MyBloc> {
  const MyHomePage({super.key});

  @override
  Widget buildPage(BuildContext context) {
    return buildLoadingOverlay(
      child: Scaffold(
        appBar: AppBar(title: const Text('My Page')),
        body: BlocBuilder<MyBloc, MyState>(
          builder: (context, state) {
            return Text('${state.someData}');
          },
        ),
        floatingActionButton: FloatingActionButton(
          onPressed: () => bloc.add(const MyEvent()),
          child: const Icon(Icons.add),
        ),
      ),
    );
  }
}

This approach provides a clean and consistent way to create stateless widget pages with bloc integration, with all the necessary functionality inherited from the base class.
