body: <p>Is there a way to add a trailing icon to a <code>TextButton</code>?</p>
  <p>Here's my code:</p>
  <pre><code>TextButton(
         child: Center(
           child: Text ('Dummy', style: GoogleFonts.openSans (
               color: Colors.white, fontWeight: FontWeight.w400,
               fontSize: 28),),
         ),
         onPressed: () {
           Navigator.push(
             context,
             MaterialPageRoute(builder: (context) =&gt; FourteenthRoute(),),);
         }
     ),
  </code></pre>
