Determining if geolocation enabled with react native

Building an app with RN I use the following to receive user's location :

 navigator.geolocation.getCurrentPosition(
  (position) => {
   //do stuff with location
  },
  (error) => {
    //error or locaiton not allowed
  },
  {enableHighAccuracy: true, timeout: 20000, maximumAge: 1000}
);

Which immediately invokes the inquiry for user to accept geolocation permissions. What I'm trying to achieve now is to have an explicit screen before prompting user to click on a button to accept those permissions. In order to get there, I need some way to check if he has accepted those permissions before or not. Caching it in storage would be a bad solution - it might go out of sync if user changes permissions in settings.

How can I check if user has accepted geolocation permissions without triggering the permission alert?
