updateBlocOnFutureChange method
Updates the Bloc
after calling change
if the value returned by
tracker
changes.
Slightly less efficient than writing the code yourself, but reduces boilerplate.
Unlike the similar updateBlocOnChange, this supports the change function returning a super.
Implementation
Future<void> updateBlocOnFutureChange({
required Future<dynamic> Function() change,
required List<dynamic> Function() tracker,
}) async {
final track = tracker();
await change();
if (!_equality(track, tracker())) {
updateBloc();
}
}
