listenSelf abstract method

  1. void listener(
    1. AsyncValue<List<UserNote>>? previous,
    2. AsyncValue<List<UserNote>> next

Listens to changes on the value exposed by this provider.

The listener will be called immediately after the provider completes building.

As opposed to listen, the listener will be called even if ProviderElementBase.updateShouldNotify returns false, meaning that the previous and new value can potentially be identical.

Implementation

@Deprecated('Will be removed in 3.0. Use Notifier.listenSelf instead')
void listenSelf(
  void Function(State? previous, State next) listener, {
  void Function(Object error, StackTrace stackTrace)? onError,
});
