Possibility of manually returning AsyncValue.loading in AsyncNotifier.build()

[andreadaoud]

Hi,

I would like to return AsyncValue.loading in AsyncNotifier.build. Is it possible?

For example:

class VolumeNotifier extends AsyncNotifier<double> {
  @override
  Future<double> build() async {
    // client is AsyncValue<ApiClient> which can be AsyncValue.loading
    final client = ref.watch(clientProvider);
    if (!client.hasValue) {
      // Instead of returning a default value zero here, I would like to return AsyncValue.loading()
      // But dart doesn't provide Future.never
      return Future<double>.value(0.0);
    }
    // If API client is available, just get the volume
    return await client.getVolume();
  }
}

Thanks in advance!

No. But you might be able to return this.future

Thank you, it works

Why not use final client = await ref.watch(clientProvider.future);?
