Generate Stateprovider using riverpod_generator

[wurikiji]

I'd like to generate StateProvider using riverpod_generator.
But I found that there are only four types of provider, provider, futureProvider, notifier, and asyncNotifier, in the generator code.
Do I have to use StateNotifier or ChangeNotifier even for simple state management?

StateProvider is simple without the generator. I'm curious why you are wanting to generate it specifically. The generator makes StateNotifier providers simpler by letting you define methods directly on a class and not splitting up the definition of the class and the definition of the provider.

You can freely use regular riverpod and generated riverpod together.

In the long run, assuming metaprogramming isn't canceled, the old syntax will likely be deprecated.
It's far in the future though.

There is no plan for now to have a StateProvider equivalent in the code generator.

Making a class and generating a Notifier is the recommended solution for now.

I suggest documenting this on the website. :)

Just now I ran into:

Generated providers should only depend on other generated providers. Failing to do so may break rules such as "provider_dependencies".dart(avoid_manual_providers_as_generated_provider_dependency)

Reason being a state provider has been watched.

@rrousselGit wdyt, is this worth documenting?

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
