Flutter —— TabBarView每次进入都刷新？
import 'package:flutter/material.dart';
class PageOne extends StatefulWidget {
const PageOne({Key? key}) : super(key: key);
@override
_PageOneState createState() => _PageOneState();
}
class _PageOneState extends State<PageOne> with AutomaticKeepAliveClientMixin {
@override
bool get wantKeepAlive => true;
@override
void initState() {
super.initState();
print("pageone");
}
@override
Widget build(BuildContext context) {
super.build(context);
return Scaffold(
body: Center(
child: Text("pageone"),
),
);
}
}
