deprecated 됐기 때문에 대체 방법

// 액티비티

//콜백 객체 생성
private val callback = object : OnBackPressedCallback(true) {
        override fun handleOnBackPressed() {
            // 뒤로가기 이벤트 여기에서 처리
        }
    }
    
 ...
 
 // 콜백 붙여주기. (onCreate나 함수에서)
 this.onBackPressedDispatcher.addCallback(this, callback) 
 
 
 
 
 // 프래그먼트
 class MyFragment : Fragment() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        // This callback is only called when MyFragment is at least started
        val callback = requireActivity().onBackPressedDispatcher.addCallback(this) {
            // Handle the back button event
        }

        // The callback can be enabled or disabled here or in the lambda
    }
    ...
