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

i achieved this using this simple trick

val bottomSheetDialog = FeedbackFormsFragment.createInstance()
bottomSheetDialog.show((activity as FragmentActivity).supportFragmentManager, BOTTOM_SHEET)


// add some delay to allow the bottom sheet to be visible first so that the dialog is not null

                Handler().postDelayed({
                    bottomSheetDialog.dialog?.setOnDismissListener {

                       // add code here
                    }
                }, 1000)
