[英]Flutter floating action button in a CustomScrollView
Is there any way to include a Floating Action Button in a screen consisting of a CustomScrollView with a SliverAppBar and a SliverList? 有什么方法可以在由带有SliverAppBar和SliverList的CustomScrollView组成的屏幕中包括一个浮动动作按钮吗?
I want to be able to have the default behaviour of a sliver list with a FAB fixed on the screen. 我希望能够在屏幕上固定有FAB的情况下,具有银条列表的默认行为。
Is it possible? 可能吗?
You can still use the Scaffold when you're using the SliverAppBar such as: 使用SliverAppBar时,仍然可以使用Scaffold,例如:
new Scaffold(
body: new CustomScrollView(
slivers: <Widget>[
new SliverAppBar(...),
...
],
),
floatingActionButton: new FloatingActionButton(...),
);
Otherwise, you can generally use a Stack above the CustomScrollView and the FloatingActionButton (in a Positioned) as well. 否则,通常也可以在CustomScrollView和FloatingActionButton(位于Positioned)上方使用Stack。
