title: React native navigation cross screens notification "snackbar"
body: <p>Trying to implement a "No internet" notification across alot of screens in react native using react-navigation. I'm trying to avoid adding the component to all screen views render function since it feels like boilerplate. </p>
  
  <p>Is there a simple way to add a component in one place using react native navigation and have it persist in all screens?</p>
