body: <p>How can I remove title bar on flutter bar?</p>
  
  <pre><code>displayMap() {
      mapView.show(new MapOptions(
          mapViewType: MapViewType.normal,
          initialCameraPosition:
          new CameraPosition(new Location(11.052992, 106.681612), 3.0),
          showUserLocation: false,
          title: 'Google Map'));
  
           .....
    }
  </code></pre>
  
  <p>I tried add <code>Container(height: 0.0)</code> and remove <code>title: 'Google Map'</code> but it only remove 'Google Map' text.</p>

  <pre><code>Widget build(BuildContext context) {
      return new Scaffold(
        appBar: new AppBar(
          title: new Text('Demo App'),
        ),
        body: new Center(
          child: Container(
            child: RaisedButton(
              child: Text('Touch'),
              color: Colors.blue,
              textColor: Colors.white,
              elevation: 7.0,
              onPressed: displayMap,
            ),
          ),
        ),
      );
    }
