title: How do I get the current item displayed in a FlatList?
body: <p>I'm using a flatlist to render a feed of videos for my project. I want to prevent the videos from auto-playing when they're not visible on the screen.
  I figured the simplest way to do this would be to see if the current video on the screen is currently visible/active and if so, I can set props to true for playing etc.</p>
  <p>I'm having a lot of issues trying to achieve this however an I wanted to know if anyone can give me some pointers as I'm new to React-Native.</p>
