this property is not missing in SliverAppBar widget it's like AppBar Widget but you don't need to 'appBar:' property in Scaffold Widget, you need 'body:' property and on it you must add CustomScrollView Widget, and in 'slivers:' property you can add list of Widgets starting from SliverAppBar, and as you like you can add SliverList, SliverGrid, I tried that and it's done, this is my code. Scaffold( body: CustomScrollView( slivers: [ SliverAppBar( expandedHeight: 180, title: Text('RoundedRectangleBorder'), shape: RoundedRectangleBorder( borderRadius: BorderRadius.vertical( bottom: Radius.circular(40), ), ), ), ], ), );
