@override
void onError(DioException exception, ErrorInterceptorHandler handler) {
  if (error) {
    if (exception.type == DioExceptionType.badResponse) {

      _printBoxed(
        _logPrintError,
        header:
            'DioException ║ Status: ${exception.response?.statusCode} ${exception.response?.statusMessage}',
        text: uri.toString(),
      );
      if (exception.response != null && exception.response?.data != null) {
        _logPrintError('╔ ${exception.type.toString()}');
        _printResponse(_logPrintError, exception.response!);
      }
      _printLine(_logPrintError, '╚');
      _logPrintError('');
    } else {
      _printBoxed(
        _logPrintError,

        text: exception.message,

      _printRequestHeader(_logPrintError, exception.requestOptions);
