i would like to just write

val router by inject<RouterViewModel>()

but its a compilation error

[Pedro Alberto]

it's a view model you can use

val router: RouterViewModel by viewModel()

[abbic]

its not really a viewmodel :p

[Pedro Alberto]

but you need to provide like viewmodel

[abbic]

im not on android

[Pedro Alberto]

ohhh ok sorry 😞

[Pedro Alberto]

but where are you trying to inject ?

[abbic]

Inside a Composable function

[abbic]

sorry i accidentally split up my question into 2 messages

[abbic]

(i am using compose multiplatform for desktop jvm)

[Pedro Alberto]

oh wow nice

[Pedro Alberto]

but the class where you trying to inject that is extending KoinComponent ?

[abbic]

the Composable isnt inside a class

[abbic]

its a global function

[Pedro Alberto]

for composable there is other dependency

[Pedro Alberto]

https://insert-koin.io/docs/quickstart/android-compose/

[Pedro Alberto]

but am not sure if this only works for view models

[Pedro Alberto]

since the injection looks like this

[Pedro Alberto]

@Composable
fun ViewModelInject(userName : String, viewModel: UserViewModel = koinViewModel()){
    Text(text = viewModel.sayHello(userName), modifier = Modifier.padding(8.dp))
}

[abbic]

theres another example

@Composable
fun FactoryInject(userName : String, presenter: UserStateHolder = get()){
    Text(text = presenter.sayHello(userName), modifier = Modifier.padding(8.dp))
}

[abbic]

but i think that if i tried to use just get, it would still ask me to provide a class parameter

[Pedro Alberto]

so just to undesrtand your RouterViewModel need attributes from the composable ?

[abbic]

let me share a bigger snippet

[abbic]

im early in the project so this is the majority of my code :P

@Composable
@Preview
fun App() {
     val router by inject<RouterViewModel>(RouterViewModel::class.java)

     val routerState: Backstack<AppRoutes> by router.observeStates().collectAsState()

     routerState.renderCurrentDestination(
          route = {
               appRoute ->
               when(appRoute) {
                    AppRoutes.Home -> {
                         HomeScreen()
                    }
               }
          },
          notFound = {}
     )
}

fun main() = application {
    startKoin {
        modules(appModule)
    }
    Window(onCloseRequest = ::exitApplication) {
        App()
    }
}

[abbic]

so you see, theres not too much going on. and, to note, this code works

[abbic]

the inject im using isnt from \a class that implements KoinContainer

[abbic]

but the KoinJavaContainer object

[Pedro Alberto]

maybe is the wrong import ?

[Pedro Alberto]

not sure sisnce I never used koin in KMM
