build method

Implementation

@override

  final spaceId = arg;

  if (relatedSpaces.knownSubspaces.isNotEmpty) {

  }
  if (relatedSpaces.hasMore) {
    // there might be some, but we need to confirm remotely. We do that without blocking
    listener = ref.listen(remoteSubspaceRelationsProvider(spaceId),
        (previous, next) {
      state = next.whenData((data) => data.isNotEmpty);
    });
  }
  return false; // until confirmed, we assume no
}
