Flutter 中 RecyclerView 的替代品是什么?

What is the alternative to RecyclerView in Flutter?

Flutter 中回收视图的替代方法是什么我尝试使用此代码 但是如何在 flutter

中使用列表视图小部件进行动画处理

这有效吗?

 ListView(
 children: <Widget>[
ListTile(
  leading: Icon(Icons.map),
  title: Text('Map'),
),
ListTile(
  leading: Icon(Icons.photo_album),
  title: Text('Album'),
),
ListTile(
  leading: Icon(Icons.phone),
  title: Text('Phone'),
  ),
 ],
);

您还可以使用 animatedlist 小部件制作动画。代码示例如下link.

AnimatedList

ListView:

通常这应该与少量子项一起使用,因为列表也会构造列表中的不可见元素,大量元素可能会导致效率低下。

ListView.builder():

列表项是惰性构建的,这意味着只构建特定数量的列表项,当用户向前滚动时,较早的列表项将被销毁。

The recommended, efficient, and effective way to build a list uses a ListView.Builder. This method is great when you have a dynamic List or a List with very large amounts of data. This is essentially the equivalent of RecyclerView on Android, which automatically recycles list elements for you:

@override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: Text("Sample App"),
        ),
        body: ListView.builder(
            itemCount: widgets.length,
            itemBuilder: (BuildContext context, int position) {
              return getRow(position);
            }));
  }

  Widget getRow(int i) {
    return GestureDetector(
      child: Padding(
          padding: EdgeInsets.all(10.0),
          child: Text("Row $i")),
      onTap: () {
        setState(() {
          widgets.add(getRow(widgets.length + 1));
          print('row $i');
        });
      },
    );
  }
