Description
Steps to Reproduce
- Run this Code:
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return const MaterialApp(
title: 'Flutter Demo',
home: MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({Key? key}) : super(key: key);
@override
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
List<String> items = List.generate(5, (index) => 'Tile $index');
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(),
body: ReorderableListView.builder(
buildDefaultDragHandles: false,
itemBuilder: (context, index) {
return ListTile(
trailing: ReorderableDragStartListener(
index: index,
child: const Icon(Icons.drag_indicator),
),
key: Key('$index'),
title: Text(items[index]),
);
},
itemCount: items.length,
onReorder: (int oldIndex, int newIndex) {
setState(() {
if (oldIndex < newIndex) {
newIndex -= 1;
}
final item = items.removeAt(oldIndex);
items.insert(newIndex, item);
});
}));
}
}Expected results:
It should behave like all the children.
Actual results:
