title: Get random item from Firebase
body: <p>I searched for it, but all the answers are pretty old so maybe there is a better way. I'm trying to get a random item from a Firebase DB which looks like this:</p>
  <p><a href="https://i.stack.imgur.com/RLk3f.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/RLk3f.png" alt="enter image description here" /></a></p>
  <p>I want to get a random user, that is all.</p>
  <p>Any ideas?</p>
