Is there a way to detect swipe down action on a SliverAppBar?












1















I have a SliverAppBar and I want to detect swipe down actions on the same. Is there a way to do it?



Here's what my code looks like.



CustomScrollView(
slivers: <Widget>[
SliverAppBar(
expandedHeight: 200.0,
floating: true,
flexibleSpace: FlexibleSpaceBar(
background: Column(
children: <Widget>[
<my custom widget tree>
],
),
),
),
<other sliver widgets>
],
),

  • GestureDetector is used to detect every gestures.

  • But CustomScrollView.slivers only takes a list of sliver widgets, if I wrap it inside a GestureDetector, it gives me an error.

You can wrap the sliverAppBar with NotificationListener and listen for ScrollNotifications
