Show loading on refresh provider

[samanzamani]

Hi
I have generated a viewmodel that fetches data from the network. When ViewModel goes to the AsyncError state and the user pushes the refresh button, the provider state does not go to the AsyncLoading state.
I tried the when method, and it works. Any idea why it doesn't work with the switch?

Switch method

_Loading just shows in the init state and doesn't show on refresh

@riverpod
class PackageViewModel extends _$PackageViewModel {
  @override
  Future<PackageListEntity> build() async {
    // fetch data from network and return
  }
}

class BuyPackagePage extends HookConsumerWidget {
  const BuyPackagePage({super.key});

  @override
  Widget build(BuildContext context, WidgetRef ref) {
    final AsyncValue<PackageListEntity> viewModel =
        ref.watch(packageViewModelProvider);
    return switch (viewModel) {
      AsyncData(:final value) => _Content(packageListEntity: value),
      AsyncError() => _Error(onRetry: () {
        ref.invalidate(packageViewModelProvider);
      })),
      _ => const _Loading(),
    };
  }
}

When method

_Loading shows in the init and refresh states

@riverpod
class PackageViewModel extends _$PackageViewModel {
  @override
  Future<PackageListEntity> build() async {
    // fetch data from network and return
  }
}

class BuyPackagePage extends HookConsumerWidget {
  const BuyPackagePage({super.key});

  @override
  Widget build(BuildContext context, WidgetRef ref) {
    final AsyncValue<PackageListEntity> viewModel =
        ref.watch(packageViewModelProvider);
    
    return viewModel.when(
        skipLoadingOnReload: false,
        skipLoadingOnRefresh: false,
        data: (value) => _Content(packageListEntity: value),
        error: (_, __) =>
            _Error(onRetry: () {
              ref.invalidate(packageViewModelProvider);
            }
            ),
        loading: () => const _Loading()
    );
  }
}

AsyncError needs arguments. Use it like this.

Hi @snapsl
Thank you for your help.
Actually, there are three parameters in AsyncError which extended from AsyncValue named: isLoading, isRefreshing, and isReloading can be used for different scenarios.
I changed my code to AsyncError(isLoading:false) => _Error(), and now it works as I expected.
