dart complains when trying to return a future

[chiptus]

Thanks for the work done on this package.

I'm trying to limit calls to https://pub.dev/packages/geocode to 1 per second, because of the API limit.

I created the following class:

class DebouncedGeoCode {
  final GeoCode geoCode = GeoCode();
  final debouncer =
      Debouncing<Address?>(duration: const Duration(milliseconds: 1000));

  Future<Address?> reverseGeocoding(
      {required double latitude, required double longitude}) async {
    return debouncer.debounce(() =>
        geoCode.reverseGeocoding(latitude: latitude, longitude: longitude));
  }
}

dart complains:

The return type 'Future<Address>' isn't a 'Address?', as required by the closure's context.

reversGeocoding returns Future<Address>

I fixed it by using

class DebouncedGeoCode {
  final GeoCode geoCode = GeoCode();
  final debouncer =
      Debouncing<Future<Address>>(duration: const Duration(milliseconds: 1000));

  Future<Address?> reverseGeocoding(
      {required double latitude, required double longitude}) async {
    var response = await debouncer.debounce(() =>
        geoCode.reverseGeocoding(latitude: latitude, longitude: longitude));
    return await response;
  }
}

which makes sense, the debouncer don't need to know if the value is a Future
