title: Flutter container inside a container
body: <p>I'm practicing with flutter Container these days, and this example I came up with is simply astonishing</p>
  
  <p>I put a Container of size 50x50 inside a Container of size 200x200. Strange is that the inner Container expand to 200x200 even though it has a tight constraint of 50x50.</p>
  
  <p>Here's the code</p>
  
  <pre><code>Container(
    width: 200.0,
    height: 200.0,
    color: Colors.orange,
    child: Container(
      width: 50.0,
      height: 50.0,
      color: Colors.blue,
    ),
  )
  </code></pre>
  
  <p>I expect a small blue box inside a bigger orange box.</p>
  
  <p>Could someone explain why?</p>
