Programmatically trigger a CupertinoSliverRefreshControl refresh

[edwardez]

In RefreshIndicator we have RefreshIndicatorState.show() which let developers programmly trigger a refresh.

It would be nice if we can see something similiar in CupertinoSliverRefreshControl

RefreshIndicator支持取消刷新的操作，
希望CupertinoSliverRefreshControl也能支持取消刷新的功能

Any news for that?

You can attach a scroll controller to the scroll view and animate it to a negative number, this will trigger the refresh.

scrollController.animateTo(-70,
        duration: const Duration(milliseconds: 200), curve: Curves.ease);

Ideally, the Material RefreshIndicator could adapt its look and feel for iOS and one API would suffice.
