Bad state: No ProviderScope found in flutter consumer component

When I add flutter consumer component in flutter like this:

SliverPadding(
                        padding: const EdgeInsets.symmetric(vertical: 8.0),
                        sliver: Consumer(
                              (context, read) {
                            return read(storiesTypeProvider(articleRequest)).when(
                              loading: () {
                                // return SliverFillRemaining(
                                // child: Center(child: CircularProgressIndicator()));
                                return SliverToBoxAdapter(child: Center(child: LoadingItem()));
                              },
                              error: (err, stack) {
                                print(err);
                                return SliverToBoxAdapter(
                                    child: Center(child: Text('Error: $err')));
                              },
                              data: (ids) {


                                //return StoryList(ids: ids,storiesType: articleRequest.storiesType,);
                              },
                            );
                          },
                        ),
                      )

shows this error:

flutter: [debug] Capture from onError 'package:flutter/src/widgets/nested_scroll_view.dart': Failed assertion: line 806 pos 14: 'position.hasContentDimensions && position.hasPixels': is not true.

now I am using fish-redux to manage my flutter state, should I must using ProviderScope? what should I do to fix this problem? this is the storiesTypeProvider:

final storiesTypeProvider = FutureProvider.family((ref, type) async {
  return await Repo.getArticles(type);
});

If you use flutter_riverpod. You need to add ProviderScope to the main() function. Like this:

void main() {
   runApp(ProviderScope(child: MyApp()));
}
