title: How to add shadow to the text in flutter?
body: <p>I searched for the shadow option in TextStyle, but I didn't find it. So I ask: how can I add shadow to the text in flutter? Is it possible?
  Example:</p>
  
  <pre><code>new Text(
  "asd"
  style: new TextStyle( 
  //add shadow?
  ));
  </code></pre>
