reference.get().addOnCompleteListener(new OnCompleteListener<DocumentSnapshot>() {
    @Override
    public void onComplete(@NonNull Task<DocumentSnapshot> task) {
        if(task.getResult().exists()){
            SkinType = task.getResult().getString("SkinType");
        

        }
    }
});

I want to use SkinType String out of the method on complete

    The Firestore APIs (and pretty much all modern cloud APIs) are asynchronous, meaning that you can't return the data from `onComplete` to the outer scope. Any code that needs `SkinType` will need to be inside `onComplete`, be called from there (e.g. with a custom callback), or be otherwise synchronized. This has been covered many times before already, so I linked some existing answers. If you're struggling to make those work for you, it is much more likely that someone can help if you [show what you tried already](http://stackoverflow.com/help/mcve) from those links. – Frank van Puffelen May 15 '22 at 00:08
