Implementation

@override
void onResponse(Response response, ResponseInterceptorHandler handler) async {
  if (response.statusCode == 200) {
    dynamic data = response.data;
    if (data is String) {
      handler.next(response);
    } else {
      Map dict = data;
      int code = 0;
      if (dict.containsKey('code')) {
        code = dict['code'];
      }
      String message = '';
      if (dict.containsKey('message') == true) {
        message = dict['message'];
      }

      handler.next(response);
    }
  } else {
    handler.reject(
        DioException(
          requestOptions: response.requestOptions,
          response: response,
          type: DioExceptionType.badResponse,
          error: "data error",
        ),
        true);
  }
}
