我的应用程序可以在我的设备上完美运行,但是在日志消息中,我收到一条错误消息,提示需要使用pageView。 This is the error I get when I swipe。 所以我希望有人能帮我解决每次我在设备上滑动时不断出现的错误
void main()
{
SystemChrome.setPreferredOrientations([DeviceOrientation.portraitUp])
.then((_) {
runApp(new MyApp());
});
}
class MyApp extends StatelessWidget
{
@override
Widget build(BuildContext context)
{
final tabController = new DefaultTabController(
length: 4 ,
child: new Scaffold(
appBar: new AppBar(
backgroundColor: Colors.lightGreen,
title: new Text("Discover Zambia"),
bottom: new TabBar(
indicatorColor: Colors.red,
indicatorWeight: 4.0,
tabs: [
new Tab(icon: new Icon(Icons.home),text: "Home"),
new Tab(icon: new Icon(Icons.landscape),text: "Sights"),
new Tab(icon: new Icon(Icons.local_drink),text: "Nightlife"),
new Tab(icon: new Icon(Icons.restaurant),text: "Foods")
]),
),
body: new TabBarView(
children: [
new Home(),
new Sights(),
new Nightlife(),
new Foods()
]
),
));
return new MaterialApp(
debugShowCheckedModeBanner: false,
title: "",
home: tabController,
);
}
}
