title: How to show emoji on button click that animates then disappears in flutter
body: <p>So I'm developing this game called Tap Tap, and what is required is that when I click a button a like emoji should appear, animate to top then disappear, kinda like when like button is clicked in instagram, a heart appears.</p>
  
  <p>How can I achieve something like this in flutter, I don't want anything fancy, just the emoji to show for like a second, animate then disappear.</p>
