title: Flutter: why Image.network cannot load image
body: <p>I launch the app without network. 
  Then I make network available and click setState button, the image is still not visible.
  Is there a solution?</p>
  
  <pre><code>  @override
    Widget build(BuildContext context) {
      return Scaffold(
          appBar: AppBar(
            title: Text(widget.title),
          ),
          body: Column(
            children: &lt;Widget&gt;[
              Container(
                color: Colors.blue,
                child: Image.network(
                    'https://ss2.bdstatic.com/70cFvnSh_Q1YnxGkpoWK1HF6hhy/it/u=3500755592,262843410&amp;fm=26&amp;gp=0.jpg'),
                width: 100,
                height: 100,
              ),
              RaisedButton(
                child: Text('setState'),
                onPressed: () {
                  setState(() {});
                },
              ),
            ],
          ));
    }
  </code></pre>
