Callback Once Snackbar Disappears

[Ray Massung]

I'm not sure if this exists currently or not but a good feature would be a callback so when the dialog disappears you can run a function. Prefect for any undo button, simply don't do anything until the callback is called.

There's already a built in method to do this. Just set a OnVisibiltyChangeListener like so:

.withVisibilityChangeListener(new SnackBar.OnVisibilityChangeListener() {
        @Override
        public void onShow(int stackSize) {
            Log.i("SNACKBAR", "onShow Snacks left to show: "+stackSize);
        }

        @Override
        public void onHide(int stackSize) {
            Log.i("SNACKBAR", "onHide Snacks left to show: "+stackSize);
        }
})
