Try this:

ListView(   // This next line does the trick.   scrollDirection: Axis.horizontal,   children: <Widget>[
    Container(
      width: 160.0,
      color: Colors.red,
    ),
    Container(
      width: 160.0,
      color: Colors.blue,
    ),
    Container(
      width: 160.0,
      color: Colors.green,
    ),
    Container(
      width: 160.0,
      color: Colors.yellow,
    ),
    Container(
      width: 160.0,
      color: Colors.orange,
    ),   ], ),
