title: How to retrieve data in an order from Firestore in reverse order?
body: <p>I am making this Quiz android application where I will be storing the record of each user's individual highscore in Cloud FireStore. So I made this collection named users which only has 2 fields- username and highscore. I want to retrieve the username and highscore of the top ten players globally from there to display in the leaderboard. Please let me know how I can do it! Also will it be possible to get the current user's rank?</p>
