Is it possible to set a RiverPod FutureProvider as a widget property?

The reason being that I have a widget that is being used in two different use cases, and I have a distinct FutureProvider for each use case.

e.g.

final findGoalsByPageProvider = FutureProvider.autoDispose.family<GdGoalPageResponse, int>((ref, aPageNumber) async {
  final aPageSize = ref.watch(userPreferencesProvider.select((value) => value.listPageSize));
  final aParams = ref.watch(selectGoalFilterProvider);
  aParams.page = GdPage.page(aPageNumber, aPageSize);
  final aRes = await ref.watch(goalServiceProvider).findHierListPage(aParams);
  return GdGoalPageResponse(pageNumber: aPageNumber, pageSize: aPageSize, goals: aRes);
});


class MyWidget {
  final  FutureProvider.autoDispose.family<GdGoalPageResponse, int> provider;  <== this doesn't work

}

Any suggestions?

You should not be passing the provider. You should be passing its value. Use ref.watch in the parent widget, and pass the value of that watch into the child widget as a parameter.

If you have many similarly behaved providers, you should make it a family and pass the family key, not the provider.

The answer is....

 final AutoDisposeFutureProviderFamily<GdGoalPageResponse, int> provider;
