The argument type 'AutoDisposeNotifierProviderImpl<FavoritesId, List<String>>' can't be assigned to the parameter type 'AlwaysAliveProviderListenable<dynamic>'

[abikko]

Code:

import 'package:riverpod_annotation/riverpod_annotation.dart';

part 'favorites_id.g.dart';

@riverpod
class FavoritesId extends _$FavoritesId {
  @override
  List<String> build() {
    return [];
  }

  void addFavorite(List<String> values) {
    List<String> list = state.addAllInState(values);
    state = list;
  }
}

Just runned with flutter pub run build_runner build
and also have pubspec.yaml:

dependencies:
  flutter_riverpod: ^2.0.2
  riverpod_annotation: ^1.0.4
  

dev_dependencies:
  build_runner: ^2.3.2
  riverpod_generator: ^1.0.6

Tried to use
Note that in here ref is a default Ref.
ref.watch(favoritesIdProvider); but also gives an error: "The argument type 'AutoDisposeNotifierProviderImpl<FavoritesId, List>' can't be assigned to the parameter type 'AlwaysAliveProviderListenable'"

And when I wrote the code:
ref.read(favoritesIdProvider)

Also, tried to make like (ref as WidgetRef).watch(favoritesIdProvider); and it works. Upd: not, it throws an error.

It's ok, but I need to listen the changes.

But in the docs you mentioned that we can use ref.watch(providerRef)

That's expected. Doing state = expects the state to be immutable. Either clone the list instead of using List.add; or use ref.notifyListeners()

Thanks for correction.

@rrousselGit But I mean another problem, that Ref class does not expect that I will use generated provider.

[rrousselGit]

Ah well, that error is explained in the docs https://riverpod.dev/docs/concepts/modifiers/auto_dispose/#the-argument-type-autodisposeprovider-cant-be-assigned-to-the-parameter-type-alwaysaliveproviderbase

[abikko]

@rrousselGit Oh, my bad. I got it.

I was having this issue with riverpod generator

I couldn't figure out what was going wrong, then I realized it's because my Ref parameter should use the generated type instead of the base Ref type
