  <p><strong>So I Tried Stack for this but couldn't make it perfect.
  Here is my code and image</strong></p>
  <pre><code>Stack(
     children: [
        Positioned(
           child: Container(
              height: 150,
              width: 150,
              decoration: BoxDecoration(
                 borderRadius: BorderRadius.circular(10.0),
                 color: Colors.yellow,
                 ),
              ),
           ),
        Positioned(
           child: Container(
           height: 250,
           width: 250,
           decoration: BoxDecoration(
              borderRadius: BorderRadius.circular(10.0),
              color: Colors.red,
              ),
           ),
           top: 10,
           left: 5,
           right: 5,
         ),
    ],),
  </code></pre>
