  final String url;
  final String thumbnailUrl;

  const Photo({
    required this.albumId,
    required this.id,
    required this.title,
    required this.url,
    required this.thumbnailUrl,
  });

  factory Photo.fromJson(Map<String, dynamic> json) {
    return Photo(
      albumId: json['albumId'] as int,
      id: json['id'] as int,
      title: json['title'] as String,

        .get(Uri.parse('https://jsonplaceholder.typicode.com/photos'));

    return GenericJsonParser.parseJsonListInBackground(
      responseBody,
      Photo.fromJson,
    );
}

Using dio package.

Future<List<Photo>> fetchPhotos(Dio client) async {
    final response = await client
        .getUri(Uri.parse('https://jsonplaceholder.typicode.com/photos'));

    return GenericJsonParser.parseJsonListInBackground(
      responseBody,
      Photo.fromJson,
      useDioPackage: true,
    );
}
