Screen empty after rotation

Question

I need to handle screen rotation so I read about saved state and I tried to implement it bit I cant !

here is the fragment screen :

@AndroidEntryPoint
class ImagePickerFragment : Fragment() {

    private lateinit var imagePickerBinding: FragmentImagePickerBinding
    private val imagePickerViewModel: ImagePickerViewModel by viewModels {
        SavedStateViewModelFactory(activity?.applicationContext as Application, this)
    }
    private lateinit var imagePickerAdapter: ImagePickerAdapter


    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View {

        imagePickerBinding = FragmentImagePickerBinding.inflate(inflater, container, false)
        imagePickerBinding.lifecycleOwner = this
        observeImageList()
        observeSearchText()
        observeImageClicked()


        return imagePickerBinding.root
    }

    override fun onSaveInstanceState(outState: Bundle) {
        imagePickerViewModel.trigger()
        super.onSaveInstanceState(outState)
    }
private fun observeImageList() {
    imagePickerViewModel.observeImageListData.observe(
        viewLifecycleOwner,
        EventObserver { imageList ->
            initializeImageList(imageList)
        })
}

So here I should initialize viewModel with savedstate but this getting error :

And this is My view model :

@HiltViewModel
class ImagePickerViewModel @Inject constructor(
    private val imageListUseCase: ImageListUseCase,
    private val responseManager: ResponseManager,
    private val savedStateHandle: SavedStateHandle
) : BaseViewModel() {

    private val _observeImageListData :
        MutableLiveData<Event<ArrayList<Image>>> = savedStateHandle.getLiveData("key")

  fun trigger() {
        savedStateHandle.set("key", _observeImageClicked.value)
    }

Please can any one help me ? I cant understand it well or implement it right so what's wrong?
