getDetailsByPlaceId() not working after nullsafety upgrade

[lisaerikssonw]

Hi,

After upgrading to flutter_google_places: ^0.3.0, getting place details is not working. _places.autocomplete is working fine, but when I run getDetailsByPlaceId() using placeId from one of the Predictions, I get "type 'Null' is not a subtype of type 'String' in type cast".

_places = GoogleMapsPlaces(apiKey: _apiKey);

_autocompleteResponse = await _places.autocomplete(
      input,
      language: "se",
      components: [Component(Component.country, "se")],
      location: _position != null
          ? Location(lat: _position!.latitude, lng: _position!.longitude)
          : null,
      radius: _position != null ? 500 : null,
      types: ['address'],
    );

//...selected prediction is set - placeId is not null...

final placeId = selectedPrediction.placeId!;
final fields = ['address_component', 'geometry'];
print('Prediction placeId = $placeId');
      _detailsResponse =
          await _places.getDetailsByPlaceId(placeId, fields: fields);

Output:

OK, I found a way to get around this by adding 'name' and 'place_id' fields in my details request, since they are non-nullable in your fromJson map. Maybe it should be clarified that these fields are mandatory when using field filters?
