BaseDelegate<S extends MainBlocState> mixin

Base delegate containing shared functionality between Bloc and Cubit.

This mixin provides common functionality for state management, loading indicators, and error handling that can be used by both Bloc and Cubit implementations.

Features:

• Loading state management via showLoading and hideLoading
• Navigation support via navigator
• Common bloc integration via commonBloc
• Error handling with catchError

Type Parameters:

• S: The type of states. Must extend MainBlocState.

Usage with Bloc:

class MyBloc extends Bloc<MyEvent, MyState> with BaseDelegate<MyState> {
  Future<void> handleAsyncOperation() async {
    await catchError(
      actions: () async {
        showLoading(key: 'myOperation');
        await someAsyncWork();
        hideLoading(key: 'myOperation');
      },
    );
  }
}

Usage with Cubit:

class MyCubit extends Cubit<MyState> with BaseDelegate<MyState> {
  Future<void> handleAsyncOperation() async {
    await catchError(
      actions: () async {
        showLoading();
        await someAsyncWork();
        hideLoading();
      },
    );
  }
}
