  <p><a href="https://i.stack.imgur.com/u43a6.png" rel="nofollow noreferrer">Image</a></p>
  <p>I tried adding to my container
  <code>alignment: Alignment.bottomCenter,</code>
  but doesn't seem to work.</p>
  <p>What do I need to add?</p>
  <pre class="lang-dart prettyprint-override"><code> child: Column(
