Description

I'm loading photos from Google Photos on an Flutter app.

Detailed description

I'm not able to get pictures using a POST call with filters on. I followed the tutorial on google website but it keeps giving the error. It doesn't recognize "filters" as key of the map. Without filters it works.

API calls

Future<SearchMediaItemsResponse> getAllMedia({
    int pageSize = 25,
    String nextPageToken,
    DateTime dateFilter,
  }) async {
    String url = "https://photoslibrary.googleapis.com/v1/mediaItems:search";

    return http.post(url, headers: await _authHeaders, body: {
      "pageSize": jsonEncode(pageSize),
      "albumId": "",
      if (dateFilter != null)
        "filters": jsonEncode({
          "dateFilter": {
            "dates": [
              {
                "year": dateFilter.year,
                "day": dateFilter.day,
                "month": dateFilter.month,
              }
            ]
          }
        }),
      if (!isNullOrEmpty(nextPageToken)) "pageToken": nextPageToken,
    }).then(
      (Response response) {
        //print(response.request.toString());
        if (response.statusCode != 200) {
          print(response.reasonPhrase);
          print(response.body);
        }

        return SearchMediaItemsResponse.fromJson(jsonDecode(response.body));
      },
    );
  }

Steps to reproduce the problem

What steps will reproduce the problem?

1. Run the call above

What is the expected output?

I expected to get a List of MediaItem filtered by the datetime I provided.

What do you see instead?

I get a INVALID_ARGUMENT exception from the server.

Additional information

It doesn't like the "filters" key of the map. I tried with "filters" : "" and I've got the same error. I tried also to remove all the others parameters like token and pagesize but no way.
