BottomSheetDialogFragment - listen to dismissed by user event

Question

How can I listen to a FINAL dismissal of a BottomSheetDialogFragment? I want to save user changes on the final dismissal only...

I tried following:

Answer 1

bottomSheetDialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
   @Override
   public void onDismiss(DialogInterface dialog) {
       toast("dismissed");
   }
});
