直接上代碼吧
class HomePage extends StatefulWidget {
@override
State<StatefulWidget> createState() {
// TODO: implement createState
return HomeState();
}
}
class HomeState extends State<HomePage> {
List<Widget> pages = List();
var _currentIndex = 0;
@override
void initState() {
// TODO: implement initState
super.initState();
pages
..add(MusicPage())
..add(RadioPage())
..add(VideoPage())
..add(UserPage());
}
@override
Widget build(BuildContext context) {
// TODO: implement build
return Scaffold(
body: IndexedStack(
index: _currentIndex,
children: pages,
),
bottomNavigationBar: BottomNavigationBar(
