import 'package:http/http.dart' as http;

Future<List<Photo>> fetchPhotos(http.Client client) async {
  final response = await client.get('url here');
  return compute(parsePhotos, response.body);
}

// A function that will convert a response body into a List<Photo>
List<Photo> parsePhotos(String responseBody) {
  final parsed = json.decode(responseBody);
  return (parsed["data"]["categoryList"] as List)
      .map<Photo>((json) => new Photo.fromJson(json))
      .toList();
}
