Copy code
@Composable
fun App() {
    KoinApplication(
        application = {
            modules(
                module {
                    single<viewModelA> { viewModelA() }
                }
            )
        }
    ) {
        val a = koinInject<viewModelA>()
    }
}


class viewModelA : ViewModel() {

}
Can you try this ?
m
Also, why is the ViewModel defined as a Singleton instead of ViewModel? https://insert-koin.io/docs/quickstart/android-viewmodel/#displaying-user-with-viewmodel
g
@Muaz KADAN thanks.
@Marcello Galhardo i see some demo write as this. i'm noob for compose multiplatform
m
just use
Copy code
val viewModel: HomeViewModel = koinViewModel()
or
Copy code
val viewModel = koinViewModel<HomeViewModel>()
g
@Muaz KADAN thanks
