fixes #3522

Using ref functions of the disposed provider can lead to unexpected behaviors e.g providers may never be disposed and hang around indefinitely if subscribed to using Ref of a disposed provider.

@riverpod
Future<void> future1(Future1Ref ref) async {}

@riverpod
Future<void> future2(Future2Ref ref) async {
  await Future.delayed(const Duration(seconds: 3));
  await ref.watch(future1Provider.future);
}

In the above example future1Provider will still be watched forever if future2Provider is disposed before timer expires.

Will handle checklist items if this even correct solution.
