英雄动画
我有一个标准ListView，其中包含一些项。当位置改变时，我想以一种英雄的方式为它们设置动画。我该怎么做？感谢您提前提出任何答案。

简单的例子
import 'package:flutter/material.dart';
void main() => runApp(MaterialApp(
home: Home(),));
class Home extends StatelessWidget {
final List<String> litems = [
"Item 1","Item 2","Item 3","Item 4","Item 5","Item 6","Item 7"
];
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Hero List'),),body: ListView.builder(
itemCount: litems.length,itemBuilder: (BuildContext ctxt,int index) {
return ListTile(
title: Hero(
tag: '${litems[index]}__heroTag',child: Text(
litems[index],style: Theme.of(context).textTheme.title,trailing: IconButton(
icon: Icon(Icons.navigate_next),onPressed: () {
Navigator.push(
context,MaterialPageRoute(
builder: (context) => ItemScreen(
itemName: litems[index],)),);
}),);
},);
}
}
class ItemScreen extends StatelessWidget {
final String itemName;
const ItemScreen({Key key,@required this.itemName}) : super(key: key);
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(itemName),body: Container(
child: Center(
child: Hero(
tag: '${itemName}__heroTag',child: Text(
itemName,);
}
}
