Issue Description and Steps

dio_mixin.dart

      if (options.sendTimeout > 0) {
        byteStream.timeout(Duration(milliseconds: options.sendTimeout),
            onTimeout: (sink) {
          sink.addError(DioError(
            requestOptions: options,
            error: 'Sending timeout[${options.connectTimeout}ms]',
            type: DioErrorType.sendTimeout,
          ));
          sink.close();
        });
      }

And DioErrorType.connectTimeout has never been used.
