# Hilt integration

!!! success

To use the `getScreenModel` you should first import `cafe.adriel.voyager:voyager-hilt` (see [Setup](../setup.md)).
|
|
|
|
### @Inject
|
|
|
|
Add `@Inject` annotation to your `ScreenModel`.
|
|
|
|
```kotlin
|
|
class HomeScreenModel @Inject constructor() : ScreenModel {
|
|
// ...
|
|
}
|
|
```
|
|
|
|
Call `getScreenModel()` to get a new instance.
|
|
|
|
```kotlin
|
|
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`.
|
|
|
|
```kotlin
|
|
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.
|
|
|
|
```kotlin
|
|
data class PostDetailsScreen(val postId: Long): AndroidScreen() {
|
|
|
|
@Composable
|
|
override fun Content() {
|
|
val screenModel = getScreenModel<PostDetailsScreenModel, PostDetailsScreenModel.Factory> { factory ->
|
|
factory.create(postId)
|
|
}
|
|
// ...
|
|
}
|
|
}
|
|
```
|
|
|
|

### Navigator scoped ScreenModel
|
|
|
|
```kotlin
|
|
class HomeScreen : Screen {
|
|
|
|
@Composable
|
|
override fun Content() {
|
|
val navigator = LocalNavigator.currentOrThrow
|
|
val screenModel = navigator.getNavigatorScreenModel<HomeScreenModel>()
|
|
// ...
|
|
}
|
|
}
|
|
```
