To manage our ListView, we will want a ScrollController.

5. ScrollController _scrollController = ScrollController();
To jump listview from Top to bottom, you can use the below snippet.
onPressed: () async {
SchedulerBinding.instance?.addPostFrameCallback((_) {
_scrollController.animateTo(
_scrollController.position.maxScrollExtent,
duration: const Duration(milliseconds: 1),
curve: Curves.fastOutSlowIn);
});
},

6. To jump listview from Bottom to Top, you can use the below snippet.
onPressed: () async {
SchedulerBinding.instance?.addPostFrameCallback((_) {
_scrollController.animateTo(
_scrollController.position.minScrollExtent,
duration: const Duration(milliseconds: 1),
curve: Curves.fastOutSlowIn);
});
},

7. Let’s see a complete example of a scrolling list view of both sides.
class MyHomePage extends StatefulWidget {
const MyHomePage({Key? key}) : super(key: key);
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State {
final ScrollController _scrollController = ScrollController();
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('Coflutter'),
),
body: Column(
children: [
Row(

8. mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
ElevatedButton(
child: const Text('To Top'),
onPressed: () async {
SchedulerBinding.instance?.addPostFrameCallback((_) {
_scrollController.animateTo(
_scrollController.position.minScrollExtent,
duration: const Duration(milliseconds: 1),
curve: Curves.fastOutSlowIn);
});
},
),

9. ElevatedButton(
child: const Text('To Bottom'),
onPressed: () async {
SchedulerBinding.instance?.addPostFrameCallback((_) {
_scrollController.animateTo(
_scrollController.position.maxScrollExtent,
duration: const Duration(milliseconds: 1),
curve: Curves.fastOutSlowIn);
});
},
),
],
),

10. Expanded(
child: ListView.builder(
controller: _scrollController,
itemCount: 100,
itemBuilder: (BuildContext context, int index) {
return Card(
child: ListTile(
title: Text("Index : $index"),
),
);
},
),
),
const Divider(),
],
));
}
}
