java - Firebase Firestore : How to convert document object to a POJO on Android

With the Realtime Database, one could do this :

MyPojo pojo  = dataSnapshot.getValue(MyPojo.Class);

as a way to map the object, how does one do this with Firestore?

CODE :

FirebaseFirestore db = FirebaseFirestore.getInstance();
        db.collection("app/users/" + uid).document("notifications").get().addOnCompleteListener(task -> {
            if (task.isSuccessful()) {
                DocumentSnapshot document = task.getResult();
                if (document != null) {
                    NotifPojo notifPojo = document....// here
                    return;
                }

            } else {
                Log.d("FragNotif", "get failed with ", task.getException());
            }
        });
