error_notifier_for_provider #
A trick to notify errors in ChangeNotifier/ValueNotifier/StateNotifier.
No more GlobalKey<Scaffold>
!
Provider(
create (_) => YourObjectWithErrorNotifierMixin(),
child: Scaffold(
body: ErrorListener(
onNotify: (context, message) => Scaffold.of(context).showSnackbar(
Snackbar(content: Text(message))
)
child: YourContent(),
),
),
);
Pros #
- Easy to use
- You can use it with ChangeNotifier/ValueNotifier/StateNotifier and any other provided objects.
Motivation #
ChangeNotifier/ValueNotifier/StateNotifier can notify and reflect its state to other object. But it's for UI, not the one shot notification like an error notification.
error_notifier_for_provider
provides another path to notify something.
