LoadingBlocBuilder<B extends BlocBase<S>, S> class Null safety

A special BlocBuilder for displaying the lifecycle of a state with a LoadingStatus.

Example:

LoadingBlocBuilder<TestingBloc, TestingState>(
  statusGetter: (state) => state.status,
  initialBuilder: (_, _state) => const Text('Initial'),
  loadingBuilder: (_, _state) => const Text('Loading'),
  successBuilder: (_, _state) => const Text('Success'),
  failureBuilder: (_, _state) => const Text('Failure'),
),
