I'm trying to construct a simple login page for my Flutter app. I've successfully built the TextFields and log in/Sign in buttons. I want to add a horizontal ListView. When I run the code my elements disappear, if I do it without the ListView, it's fine again. How can I do this correctly?
return new MaterialApp( home: new Scaffold( appBar: new AppBar( title: new Text("Login / Signup"), ), body: new Container( child: new Center( child: new Column( mainAxisAlignment: MainAxisAlignment.center, children: <Widget>[ new TextField( decoration: new InputDecoration( hintText: "E M A I L A D D R E S S" ), ), new Padding(padding: new EdgeInsets.all(15.00)), new TextField(obscureText: true, decoration: new InputDecoration( hintText: "P A S S W O R D" ), ), new Padding(padding: new EdgeInsets.all(15.00)), new TextField(decoration: new InputDecoration( hintText: "U S E R N A M E" ),), new RaisedButton(onPressed: null, child: new Text("SIGNUP"),), new Padding(padding: new EdgeInsets.all(15.00)), new RaisedButton(onPressed: null, child: new Text("LOGIN"),), new Padding(padding: new EdgeInsets.all(15.00)), new ListView(scrollDirection: Axis.horizontal, children: <Widget>[ new RaisedButton(onPressed: null, child: new Text("Facebook"),), new Padding(padding: new EdgeInsets.all(5.00)), new RaisedButton(onPressed: null, child: new Text("Google"),) ],) ], ), ), margin: new EdgeInsets.all(15.00), ), ), );
