title: How to draw a simple circle in Flutter?
body: <p>Most of the tutorials I found on drawing circles on flutter were related to buttons. What if I simply want to draw a circle?</p>
  <p>One way would be with <code>ClipOval</code>:</p>
  <pre><code>ClipOval(child: Container(color: Colors.grey,width: 15, height: 15),)
  </code></pre>
  <p>What if I want to draw borders and so? <code>ClipOval</code> does not seem to be the best way to do it.</p>
