-
children的State 重写 wantKeepAlive 为true
-
children的State build 方法必须调用super.build
class _MyPageState extends State<MyPage> with AutomaticKeepAliveClientMixin{
@override
bool get wantKeepAlive => true; //重点1
@override
Widget build(BuildContext context) {
super.build(context); //重点2
return Scaffold(
appBar: AppBar(
title: Text(
'我的',
style: TextStyle(fontSize: 18, fontWeight: FontWeight.w600),
),
centerTitle: true,
backgroundColor: Color.fromRGBO(32, 32, 32, 1),
),
);
}
}
