  int get maxRetryAttempts => 2;

  @override
  bool shouldAttemptRetryOnException(Exception reason) {
    log(reason.toString());

    return false;
  }

  @override
  Future<bool> shouldAttemptRetryOnResponse(BaseResponse response) async {
    if (response.statusCode == 401) {
      log("Retrying request...");
      final cache = await SharedPreferences.getInstance();

      cache.setString(kOWApiToken, OPEN_WEATHER_API_KEY);
