title: Flutter map_view use map_view as widget
body: <p>I would like to ask on how to show the map fullscreen using the function <code>MapView.Show</code> function on <code>map_view</code> dart framework which I couldn't implement as a <code>widget</code> in flutter. see my code below:</p>
  
  <pre><code>MapView showMap() { 
    return _mapView.show(new MapOptions(
      mapViewType: MapViewType.normal,
        initialCameraPosition:
          new CameraPosition(new Location(10.31264, 123.91139), 12.0),
      showUserLocation: true,
    ));
  }
  </code></pre>
  
  <p>should be put inside the <code>child</code> in widget.</p>
  
  <pre><code>@override
  Widget build(BuildContext context) {
      return new Container(
        color: Colors.red,
        height: double.infinity,
        width: double.infinity,
        child: showMap(), // surprisingly not working
      );
    }
  </code></pre>
  
  <p>I looked into tutorials on this implementation but it seems I haven't seen any liable sources on this implementation.  Does anyone knew how to implement this one?  Thanks!</p>
  
  <p><strong>Note:</strong> I want to implement as a fullscreen widget.</p>
