title: How to change the height responsively for an icon from FontAwesomeIcons in Flutter?
body: <p>I have an Icon from <code>FontAwesomeIcons</code> and need to change its height responsively, but I cannot use <code>MediaQuery</code> because it doesn't have a height attribute, it just has a size attribute which is not responsive like using <code>MediaQuery</code> with height.</p>
  
  <p>This is my code:</p>
  
  <pre><code>Icon(
    FontAwesomeIcons.solidFlag,
    color: Colors.grey,
    size: 20,
  ),
  </code></pre>
  
  <p>And in the same screen I have this code which works responsively:</p>
  
  <pre><code>Image.asset(
    'assets/icons/handphone.png',
    width: MediaQuery.of(context).size.width * .04,
  ),
  </code></pre>
  
  <p>Could someone help?</p>
