Hilt integration

To use the getScreenModel you should first import cafe.adriel.voyager:voyager-hilt (see Setup).
@Inject
Add @Inject annotation to your ScreenModel.
class HomeScreenModel @Inject constructor() : ScreenModel {
    // ...
}
Call getScreenModel() to get a new instance.
class HomeScreen : AndroidScreen() {
​
    @Composable
    override fun Content() {
        val screenModel = getScreenModel<HomeScreenModel>()
        // ...
    }
}
@AssistedInject
Add @AssistedInject annotation to your ScreenModel and provide a ScreenModelFactory annotated with @AssistedFactory.
class PostDetailsScreenModel @AssistedInject constructor(
    @Assisted val postId: Long
) : ScreenModel {
​
    @AssistedFactory
    interface Factory : ScreenModelFactory {
        fun create(postId: Long): PostDetailsScreenModel
    }
}
Call getScreenModel() and use your factory to create a new instance.
data class PostDetailsScreen(val postId: Long): AndroidScreen() {
​
    @Composable
    override fun Content() {
        val screenModel = getScreenModel<PostDetailsScreenModel, PostDetailsScreenModel.Factory> { factory ->
            factory.create(postId)
        }
        // ...
    }
}
