Question

我有一个视图作为附件

body: TabBarView(
controller: _tabController,
children: [
    TabSreen(index: _tabController.index, eventId: widget.eventEntity.eventId),
    TabScreen(index: _tabController.index, eventId: widget.eventEntity.eventId)
    ]
),

TabScreen是StatefulWiget，单击TabScreen列表中的每个项目，然后打开SecondScreen

如何使第二个屏幕显示为全屏。我的意思是SecondView应该删除该部分：Event1，Event Name，Status。只是将导航下方的视图显示为全屏

当前，我正在使用以下代码从TabScreen打开SecondScreen（StatefulWiget）

Navigator.push(
        context,
        MaterialPageRoute(builder: (context) => new SecondScreen(title: _forms[index].name)),
    );

这是一个简单的示例，因为您没有共享足够的代码，因此您可以将其与此进行比较。

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Test',
      theme: ThemeData(
        brightness: Brightness.dark,
        primaryColor: Color(0xFF048ec8),
        indicatorColor: Colors.red,
        cursorColor: Colors.red,
      ),
      home: MainScreenWithTab(),
    );
  }
}

class MainScreenWithTab extends StatefulWidget {
  @override
  State<StatefulWidget> createState() => MainScreenWithTabState();
}

class MainScreenWithTabState extends State<MainScreenWithTab> {
  @override
  Widget build(BuildContext context) {
    return DefaultTabController(
      length: 2,
      child: Scaffold(
        appBar: AppBar(
          title: Text('Screen'),
        ),
        body: Column(
          children: <Widget>[
            TabBar(
              tabs: <Widget>[
                Tab(
                  text: 'Left',
                ),
                Tab(
                  text: 'Right',
                )
              ],
            ),
            Expanded(
              child: TabBarView(children: [
                RaisedButton(
                  child: Text('Tap for new screen'),
                  onPressed: () {
                    Navigator.push(context,
                        MaterialPageRoute(builder: (context) => Screen()));
                  },
                ),
                FlatButton(
                  child: Text('Push View 2'),
                  onPressed: () {
                    Navigator.push(context,
                        MaterialPageRoute(builder: (context) => Screen()));
                  },
                ),
              ]),
            ),
          ],
        ),
      ),
    );
  }
}

class Screen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Screen'),
      ),
      body: Container(
        width: double.infinity,
        height: double.infinity,
        color: Colors.yellow,
        child: Center(
          child: Text('New Screen'),
        ),
      ),
    );
  }
}

从TabView Flutter打开屏幕而不是全屏
