Hello, please help
I'm trying to use Koin in a KMM project with Voyager lib
My Screen

@OptIn(ExperimentalVoyagerApi::class)
data object QuestionScreen : Screen {

    override val key : ScreenKey
        get() = KEY_QUESTION_SCREEN

    @Composable
    override fun Content() {
        val navigator = LocalNavigator.currentOrThrow

        val screenModel = navigator.getNavigatorScreenModel<QuestionScreenModel>()
        //var screenModel = getScreenModel<QuestionScreenModel>()

        //objects are a list of questions
        //val objects by screenModel.getObject().collectAsState()

        val state by screenModel.state.collectAsState()

My Koin

val screenModelsModule = module {
    factoryOf(::ListScreenModel)
    factoryOf(::DetailScreenModel)
    factoryOf(::QuestionScreenModel)
}

ViewModel

class QuestionScreenModel(
    questionDataSource: SqlDelightQuestionDataSource,
) : ScreenModel {

getting the following

Any clue about what iam doing wrong? thanks

[Ciaran Sloan]

have you provided a definition for SqlDelightQuestionDataSource in a module somewhere? If not, thats your issue

[Romão]

Could you please have a look in the following repo @Ciaran Sloan

You might need to change the order of your modules in your initKoin function.
