我是从Flutter开始的,我遇到了一个我无法构建的布局,在一个可视化示例下面:
我已经尝试过类似的东西:
class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return new MaterialApp( title: 'Welcome to Flutter',home: new Scaffold( appBar: new AppBar( title: new Text('App'),),body: new Column( children: <Widget>[ new Text('LISTA',style: new TextStyle( fontSize: 15.2,fontWeight: FontWeight.bold,) ),new Container( height: 200.0,child: new ListView( children: <Widget>[ new RaisedButton( onPressed: null,child: new Text("text button"),new Padding(padding: new EdgeInsets.all(5.00)),new RaisedButton( onPressed: null,child: new Text("text button 2"),) ],) ] ) ),); } }
但是对于Container来说它需要一个高度,我需要它来占据屏幕的其余部分.
解决方法
new Column( children: <Widget>[ new Text('LISTA',style: new TextStyle( fontSize: 15.2,)),new Expanded( child: new Container( decoration: new BoxDecoration(color: Colors.blue),height: 200.0,child: new ListView( children: <Widget>[ new RaisedButton( onPressed: null,new RaisedButton( onPressed: null,) ],) ) ] )
