onError method

@override void onError(DioException err, ErrorInterceptorHandler handler)

Called when an exception was occurred during the request.

Implementation

@override
void onError(DioException err, ErrorInterceptorHandler handler) {
  final httpError = NetworkHttpError()..error = err.toString();
  if (err is Error) {
    final basicError = err as Error;
    httpError.stackTrace = basicError.stackTrace;
  }

  networkCore.addError(httpError, err.requestOptions.hashCode);
  final httpResponse = NetworkHttpResponse()..time = DateTime.now();
  if (err.response == null) {
    httpResponse.status = -1;
    networkCore.addResponse(
      httpResponse,
      err.requestOptions.hashCode,
    );
  } else {

        ..body = ''
        ..size = 0;
    } else {

    }
    final headers = <String, String>{};

    networkCore.addLog(
