是否可以用RefreshIndicator实现下拉刷新

[xiaobeiy]

ScrollViewAuto.nested在页面中间下拉刷新感觉怪怪的，是否考虑使用RefreshIndicator实现下拉刷新。
```
RefreshIndicator(
//可滚动组件在滚动时会发送ScrollNotification类型的通知
notificationPredicate: (ScrollNotification notifation) {
//该属性包含当前ViewPort及滚动位置等信息
ScrollMetrics scrollMetrics = notifation.metrics;
if (scrollMetrics.minScrollExtent == 0) {
return true;
} else {
return false;
}
},
onRefresh: handleRefresh,
child: ScrollViewAuto.nested(
body: TabBarView(),
),
),

 RefreshIndicator(
        notificationPredicate: (ScrollNotification notification) {
          // 返回true即可
          return true;
        },
        onRefresh: () async {
          //模拟网络请求
          await Future<dynamic>.delayed(const Duration(seconds: 4));
          //结束刷新
          return Future<dynamic>.value(true);
        },
        child: ScrollViewAuto.nested(
            slivers: slivers,
            body: body),
      )
