riverpod_generator for StateNotifier

[derolf]

Is there a way to use riverpod_generator to generate a StateNotifierProvider for a function returning a StateNotifier<T>?

[rrousselGit]

No.
The expected solution is to use:

@riverpod
class YourNotifier extends _$YourNotifier {
  @override
  YourState build() => YourState();
}

Thank you @rrousselGit as answer my use case as well.

Can you add a feature that would make it simpler to write?
For example:

@Riverpod(notifier: true)
int counter(CounterRef ref) => 0;

I have no plan to support StateProvider, no.

There is a package to generated the equivalent of the StateProvider:

https://pub.dev/packages/riverpod_state_provider_annotation
https://pub.dev/packages/riverpod_state_provider_generator

# main.dart
import 'package:riverpod_state_provider_annotation/riverpod_state_provider_annotation.dart';

part 'main.g.dart';
part 'main.rsp.dart';

@RiverpodStateProvider()
int myState() {
  return 0;
}

ref.watch(myStateProvider);
ref.read(myStateProvider.notifier).state++;
ref.read(myStateProvider.notifier).update((state) => state + 1);

ProviderScope(
  overrides: [
    myStateProvider.overrideWithValue(10),
  ],
)

It still has some limitations but for simple usages (usually the case for StateProvider), it does the job
