Riverpod in a custom package/library

[bytcra]

I m creating a package/library and want to implement riverpod as state management. Today I get to see the real shortcoming of Google of not understanding the context. When I try to search "Using riverpod for custom package or library" it gives me results of implementing riverpod the general way.

Anyway, I tried to find the same on the discussion thread and I might have missed out or something but I did not find the answer.

My question:
How to implement riverpod 2.0 the right way in a package where there is no main() to start with?

It widely depends on the package you want to make. Hard to say without giving your constraints.

For example, you could make a package exposing a bunch of providers. Or you could expose a bunch of widgets internally using providers, and ask for folks to wrap their app in ProviderScope (or a custom-made widget that internally uses ProviderScope)

Thank you for the reply.

This will mandate the user to install riverpod too, right? I have direct screens made of stateful widgets exposed.. what would be the best way to setup a provider scope without user needing to install riverpod in their app.

You'll need a custom wrapper widget placed above the entire app, which internally uses ProviderScope

Something like this?

class MyWidgetWrapper extends StatelessWidget {
  const MyWidgetWrapper({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return ProviderScope(child: MyWidget());
  }
}

or

class MyWidgetWrapper<T> extends StatelessWidget {
  const MyWidgetWrapper({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return ProviderScope(child: T as ConsumerWidget);
  }
}

though the second one gives me:
type '_Type' is not a subtype of type 'ConsumerWidget' in type cast

@bytcra did you find a solution?
I am trying to implement Riverpod in a custom package but I am stuck at the same point.
