class HiddenAwareLifecycle(
    fragment: Fragment,
) : LifecycleRegistry(fragment) {

    init {
        fragment.lifecycle.addObserver(
            object : DefaultLifecycleObserver {
                override fun onCreate(owner: LifecycleOwner) {
                    currentState = State.CREATED
                }

                override fun onStart(owner: LifecycleOwner) {
                    currentState = State.STARTED
                }

                override fun onResume(owner: LifecycleOwner) {
                    currentState = State.RESUMED
                }

                override fun onPause(owner: LifecycleOwner) {
                    currentState = State.STARTED
                }

                override fun onStop(owner: LifecycleOwner) {
                    currentState = State.CREATED
