Hey folks, do I need to do anything extra to use SavedStateHandle in a @KoinViewModel injected in a composable function?

Version

koin-bom = "4.1.0"
koin-annotations = "2.1.0"
kotzilla = "1.2.0-Beta1"
kotzillaPlugin = "1.2.0-Beta2"

Caused by: org.koin.core.error.NoDefinitionFoundException: No definition found for type 'androidx.lifecycle.SavedStateHandle'. Check your Modules configuration and add missing type and/or qualifier!

When I remove the SavedStateHandle from my ViewModel, everything works fine.

@Pedro Francisco de Sousa Neto share your VM setup

[arnaud.giuliani]

with Compose it should be ok on Android. Else SavedStateHandle is not fully supported on iOS

[Pedro Francisco de Sousa Neto]

Sure, @Kibet Theophilus! I will already send in channel to improve the snippet code readability.

ViewModel

@KoinViewModel
class MyViewModel(
    private val getUsers: GetUsers,
    private val savedStateHandle: SavedStateHandle
) : ViewModel(), StateMachine<UserListIntent, UserListState>

Compose

@Composable
fun MyScreen(
    viewModel: MyViewModel = koinInject(),
) {
    val state by viewModel.state.collectAsState()

    LaunchedEffect(Unit) {
        viewModel.dispatch(UserListIntent.LoadUsers)
    }

    [...]
}

> viewModel: MyViewModel = koinInject(),
use koinViewModel()

[Pedro Francisco de Sousa Neto]

Yeah, it's an Android projet @arnaud.giuliani.

[arnaud.giuliani]

koinViewModel() will trigger injection of SavedStateHandle, not koinInject()

[Pedro Francisco de Sousa Neto]

You solved it, @arnaud.giuliani. Thank you!
