Hello, I'm having an issue with coin and savedstatehandle:
Data is just null when trying to access it


Koin module and version:
4.1.0-Beta5

TypeSafe Navigation:

composable<Route.AddEditDreamScreen> { backStackEntry ->
                val args = backStackEntry.toRoute<Route.AddEditDreamScreen>()
                val image = args.backgroundID

                val addEditDreamViewModel = koinViewModel<AddEditDreamViewModel>()

                println("Dream ID: ${navController.currentBackStackEntry?.savedStateHandle?.get<String>("dreamID")}")
                AddEditDreamScreen(
                    dreamImage = image,
                    onMainEvent = { onMainEvent(it) },
                    onAddEditDreamEvent = { addEditDreamViewModel.onEvent(it) },
                    animateVisibilityScope = this,
                    onNavigateToDreamJournalScreen = {
                        navController.popBackStack()
                        navController.navigate(Route.DreamJournalScreen)
                    },
                    onImageClick = { imageID ->
                        navController.navigate(
                            Route.FullScreenImageScreen(imageID)
                        )
                    }
                )
            }

Koin:

val viewModelModule = module {
    viewModelOf(::AddEditDreamViewModel)
}

ViewModel:

class AddEditDreamViewModel(
    private val savedStateHandle: SavedStateHandle,
    private val dreamUseCases: DreamUseCases,
    private val authRepository: AuthRepository,
    private val dictionaryRepository: DictionaryRepository,
    private val vibratorUtil: VibratorUtil,
) : ViewModel() {

    private val _addEditDreamState = MutableStateFlow(
        AddEditDreamState(
            authRepository = authRepository
        )
    )
    val addEditDreamState: StateFlow<AddEditDreamState> = _addEditDreamState.asStateFlow()


    init {
        savedStateHandle.get<String>("dreamID")?.let { dreamId -> //value is Null (worked before transition to KMM)
        }
    }

This problem started after I transitioned my project from Android to KMM. Am I doing something wrong?

there is a known issue on that point, where the savedstate bundle from navigation (backstack entry) and those injected in VM are not the same. It's Android design on that.

The error ended up being some else. I was able to see it wasn't a problem with the SavedStateHandle after setting up logging.
