autoDispose constant
AutoDisposeBlocProviderBuilder
const autoDispose
Auto Dispose
Marks the provider as automatically disposed when no-longer listened.
final counterProvider1 = BlocProvider.autoDispose((ref) => CounterCubit(0));
final counterProvider2 - AutoDisposeBlocProvider((ref) => CounterCubit(0));
The maintainState
property is a boolean (false
by default) that allows
the provider to tell Riverpod if the state of the provider should be
preserved even if no-longer listened.
final myProvider = BlocProvider.autoDispose((ref) {
final asyncValue = ref.watch(myFutureProvider);
final firstState = asyncValue.data!.value;
ref.maintainState = true;
return CounterBloc(firstState);
});
This way, if the asyncValue
has no data, the provider won't create
correctly the state and if the UI leaves the screen and re-enters it,
the asyncValue
will be readed again to retry creating the state.
Implementation
static const autoDispose = AutoDisposeBlocProviderBuilder();
