title: Flutter app error - type 'Timestamp' is not a subtype of type 'DateTime'
body: <p>I'm fetching data cloud firestore &amp; trying to show in my app by using the following piece of code.</p>
  
  <pre><code>new Text(timeago.format(document.data['tripDoc']['docCreatedOn'])),
  </code></pre>
  
  <p>I'm using <code>timeago</code> dart package to format that. But, after making updating to latest cloud firestore plugin I'm getting this error -</p>
  
  <pre><code>Another exception was thrown: type 'Timestamp' is not a subtype of type 'DateTime'
  </code></pre>
  
  <p>Can't able to understand how to parse this 'TimeStamp' object to 'DateTime'. Because <code>timeago</code> plugin need data in DateTime object format.</p>
