Flutter在CustomScrollView中使用RefreshIndicator

Question

I'm working with Flutter v0.5.1

I want to build a app with SliverAppBar to auto hide when scroll up and float when scroll down. I use CustomScrollView with sliverList are SliverAppBar and MyWidget1, which is a FutureBuilder to show CircularProgressIndicator when loading data and MyWidget2 when successfully loaded data. MyWidget2 is a RefreshIndicator to user can pull to refresh data. The layout I expect is CustomScrollView -> (SliverAppBar and FutureBuilder -> RefreshIndicator)

And the problem is that I can't use RefreshIndicator in CustomScrollView because CustomScrollView need a SliverList with RenderSliver and RefreshIndicator is not.

After trying more times I find out RefreshIndicator must be inside FutureBuilder because if reverse the order RefreshIndicator would rebuild FutureBuilder and show CircularProgressIndicator when it refresh. I expect to show only RefreshIndicator. And I want to use FutureBuilder inside CustomScrollView to show SliverAppBar when FutureBuilder show CircularProgressIndicator

Any idea for me

Thank all,

Just make sure, did you try like this? RefreshIndicator -> CustomScrollView -> other silvers. It works, but you don't want to do like this, right?
