Question: Check if back stack is empty

[emartynov]

I can not find an easy way to get from the router if there is something in the back stack to pop.

Yes, it's true cause router doesn't have direct access to navigator which works with fragment manager.
Navigator lives in UI lifecycle and can be destroyed any time.
Router is independent from UI lifecycle.

But if it necessary I can add Router.getCurrentStackSize(): Int? method which returns null when navigator does not available. What do you think?
