"No StateHolder Provided" Error in Compose Multiplatform Project with Koin and Navigation

[rkshnair]

I'm encountering a runtime exception in my Compose Multiplatform project, specifically when integrating MVVM with PreCompose for navigation and Koin for dependency injection. The error occurs at the line val navigator = rememberNavigator() with the message "No StateHolder provided."

Here's the relevant portion of my code:

@Composable
fun NavHostHelper() {
    val navigator = rememberNavigator()
    NavHost(
        navigator = navigator,
        navTransition = NavTransition(),
        initialRoute = Screen.Login.route,
    ) {
        scene(
            route = Screen.Login.route,
            navTransition = NavTransition(),
        ) {
            val vm = koinViewModel(LoginViewModel::class)
            LoginScreen(vm) {
                navigator.navigate(Screen.Login.route+ "$it")
            }
        }
    }
}

Hi, have you wrapped your entry point as specified by the documentation?

https://github.com/Tlaster/PreCompose/blob/master/docs/setup.md

[Lavmee]

Can you write which version of the precompose you are using and on which platform the crash occurs?

[rkshnair]

1.5.10 and I tried Android; Didn't get a chance to check IOS.

[Lavmee]

Can you send the full crash log?

[Lavmee]

I can't reproduce this crash. Maybe you can create a minimal project with this error?

I think he talked about that one: Caused by: org.koin.core.error.NoBeanDefFoundException: No definition found for type 'moe.tlaster.precompose.stateholder.SavedStateHolder'. Check your Modules configuration and add missing type and/or qualifier! which occurs when I assume to get an Instance of SavedStateHolder in a ViewModel constructor which will be invoked by Koin.

i decided to go with voyager. So closing the thread for the time being.
