RxLoadingBuilder<B extends RxBlocTypeBase> class

RxLoadingBuilder handles building a widget in response to new LoadingWithTag states

Example:

RxLoadingBuilder<CounterBlocType>(
        state: (bloc) => bloc.states.isLoading, //Stream of type LoadingWithTag
        builder: (context, isLoading, tag, bloc) => Row(
          children: [
            ActionButton(
              tooltip: 'Increment',
              iconData: Icons.add,
              onPressed: bloc.events.increment,
              disabled: isLoading,
              loading: isLoading && tag == CounterBloc.tagIncrement,
            ),
            const SizedBox(width: 16),
            ActionButton(
              tooltip: 'Decrement',
              iconData: Icons.remove,
              onPressed: bloc.events.decrement,
              disabled: isLoading,
              loading: isLoading && tag == CounterBloc.tagDecrement,
            ),
          ],
        ),
      );
