How to add a ListView to a Column in Flutter?

Question

I'm trying to construct a simple login page for my Flutter app. I've successfully built the TextFields and Login/Signin 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),
          ),
        ),
      );

Answer 1

You can check console output. It prints error:

The following assertion was thrown during performResize(): Horizontal viewport was given unbounded height. Viewports expand in the cross axis to fill their container and constrain their children to match their extent in the cross axis. In this case, a horizontal viewport was given an unlimited amount of vertical space in which to expand.

You need to add height constraint to your horizontal list. E.g. wrap in Container with height:

new Container(
  height: 44.0,
  child: 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"),
      )
    ],
  ),
)

I've got this problem too. My solution is use Expanded widget to expand remain space.

new Column(
  children: <Widget>[
    new Expanded(
      child: horizontalList,
    )
  ],
);
