Not works well with NestedScrollView

@override
  Widget build(BuildContext context) {
    return DefaultTabController(
        length: tabs.length, //
        child: Scaffold(
            body: NestedScrollView(

                            },
                          )
                        ],

                      onRefresh: () async {
                        Future.delayed(const Duration(seconds: 1));
                      },
                    );
                  },
                ),
              );
            }).toList(),
          ),
        )));
  }
}

cn：这里的下拉刷新是有问题的，有什么方法可以解决吗？ 不想用官方提供的 nested scoll 的 demo 这样开发者会有更多的自由度，

NestedScrollView很多问题在下拉刷新中无解。非必要不建议使用NestedScrollView

感觉出现这个问题和处理sliverOverlapAbsorber有关，但换成官方提供的 RefreshIndicator 是没有问题， 看了一下RefreshIndicator实现中也没有特殊处理通过特殊方式来处理类似sliverOverlapAbsorber的情况，也没有思路了
