title: React Native - Justify Content not Working
body: <p>I've been struggling with this all over my react-native app, so I set up a very simple example of it in codesandbox which you can view here:</p>
  <p><a href="https://codesandbox.io/s/elastic-star-5754q?file=/src/App.js" rel="nofollow noreferrer">https://codesandbox.io/s/elastic-star-5754q?file=/src/App.js</a></p>
  <p>Within the View with the green background, all of the internal views are centered horizontally within their respective spaces as I would expect thanks to the &quot;alignItems: center&quot; style property. I would expect that I could also center them vertically within their spaces  by setting &quot;justifyContent: center&quot;, but that doesn't seem to work for me.</p>
  <p>Am I fundamentally misunderstanding something?</p>
