# error_notifier_for_provider

A trick to notify errors in ChangeNotifier/ValueNotifier/StateNotifier.

No more `GlobalKey`!

```dart

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.
