title: Flutter - How to control the border width of the circular progress indicator?
body: <p>I have been using the <code>CircularProgressIndicator</code> class to show a circular progress indicator with <code>SizedBox</code> class to control the size of the child widget a while ago,
  just like that :</p>
  
  <pre><code>...
  SizedBox(
    width: 20.0,
    height: 20.0,
    child: CircularProgressIndicator(
      valueColor: AlwaysStoppedAnimation&lt;Color&gt;(
      Colors.deepOrange,
      ),
    ),
  )
  ...
  </code></pre>
  
  <p>But i'm encountering that its width is exaggerated ,
  Can i reduce the width of that indicator ?</p>
  
  <p>Any suggestions or advice would be appreciated. Thanks.</p>
