title: React Native run a function on BottomTab Navigator screen on load?
body: <p>I have a Navigation Bar built using createBottomTabNavigator, this is it's own component that is added to app.js. </p>
  
  <p>When A user presses one of the buttons and are taken to a new screen, I would like for a function to load which reloads data from AsyncStorage. I am struggling to get this working, I have it loading once using useEffect, however that does not run again if I leave the page and come back. </p>
  
  <p>What is the best option for this? </p>
  
  <p>Thanks</p>
