title: React Native support of reverse flex directions
body: <p>React Native doesn't support reverse flex direction rules such as <code>row-reverse</code> and <code>column-reverse</code>. Moreover, it is specifically <code>oneOf([ 'row', 'column' ])</code>, despite what is stated in <a href="https://developer.mozilla.org/en-US/docs/Web/CSS/flex-direction" rel="nofollow">MDN docs</a>.</p>
  
  <p>My first thought was it hard to implement in native environment, but I found that one can mimic reverse behaviour simply by using <code>justifyContent: 'center'</code>. (<a href="https://rnplay.org/apps/o5Gr3Q" rel="nofollow">https://rnplay.org/apps/o5Gr3Q</a>)</p>
  
  <p>My question is, is there any explanation why these rules don't supported by React Native or it is a bug?</p>
