[flutter 3]Using a RefreshIndicator with ListView with reverse: true, doesn't show refresh indicator at the bottom #104151
Description
Since updating to flutter 3 my refresh indicator is not loading from bottom as before when ListView is set to reverse.
Tried on channel stable, and master. same behaviour. It was working as expected before
Steps to Reproduce
This can also be reproduced just going to the refreshIndicator page on flutter.dev and setting the ListView as reverse true
The code sample submitted also comes from here
https://api.flutter.dev/flutter/material/RefreshIndicator-class.html
- Execute
flutter runon the code sample - Try to overscroll the bottom, which is the beginning of the list. nothing will happen
- If you overscroll the top, the refreshIndicator gets triggered when it should be from the bottom
Expected results:
RefreshIndicator gets triggered from bottom
Actual results:
RefreshIndicator gets triggered on Top edge overscroll
This example was taken from the normal example on the RefreshIndicator page on flutter.dev
https://api.flutter.dev/flutter/material/RefreshIndicator-class.html
Code sample
import 'package:flutter/material.dart';
void main() => runApp(const MyApp());
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
static const String _title = 'RefreshIndicator Sample';
@override
Widget build(BuildContext context) {
return const MaterialApp(
title: _title,
home: RefreshIndicatorExample(title: _title),
);
}
}
class RefreshIndicatorExample extends StatefulWidget {
const RefreshIndicatorExample({Key? key, required this.title})
: super(key: key);
final String title;
@override
State<RefreshIndicatorExample> createState() =>
_RefreshIndicatorExampleState();
}
class _RefreshIndicatorExampleState extends State<RefreshIndicatorExample> {
final GlobalKey<RefreshIndicatorState> _refreshIndicatorKey =
GlobalKey<RefreshIndicatorState>();
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: RefreshIndicator(
key: _refreshIndicatorKey,
color: Colors.white,
backgroundColor: Colors.blue,
strokeWidth: 4.0,
onRefresh: () async {
return Future<void>.delayed(const Duration(seconds: 3));
},
// Pull from bottom to show refresh indicator.
child: ListView.builder(
itemCount: 25,
reverse: true, //Relevant
itemBuilder: (BuildContext context, int index) {
return ListTile(
title: Text('Item $index'),
);
},
),
),
floatingActionButton: FloatingActionButton.extended(
onPressed: () {
// Show refresh indicator programmatically on button tap.
_refreshIndicatorKey.currentState?.show();
},
icon: const Icon(Icons.refresh),
label: const Text('Show Indicator'),
),
);
}
}
