title: How to overlay Icon on image in flutter
body: <p>I have to show a favourite icon on bottom right corner of image.</p>
  
  <pre><code>Container(
     decoration: new BoxDecoration(color: Colors.white),
     alignment: Alignment.center,
     height: 240,
     child: Image.network(used_car.imageUrl,fit: BoxFit.fill) 
  )
  </code></pre>
  
  <p>I want to show an icon <code>Icon.favorite</code> on bottom right of this image container. But not find any flutter property to fix that or show that.</p>
