# ViewModel KMP
|
|
|
|
Since 1.1.0-beta01 we have introduce a experimental API for ViewModel KMP. It is under the package `cafe.adriel.voyager:voyager-lifecycle-kmp` (see [Setup](../setup.md)).
|
|
|
|
You will need to call `ProvideNavigatorLifecycleKMPSupport` before all `Navigator` calls and it will be working out of the box.
|
|
|
|
```kotlin
|
|
@Composable
|
|
fun MainView() {
|
|
ProvideNavigatorLifecycleKMPSupport {
|
|
Navigator(...)
|
|
}
|
|
}
|
|
|
|
class MyScreen : Screen {
|
|
@Composable
|
|
fun Content() {
|
|
val myViewModel = viewModel { MyScreenViewModel() }
|
|
}
|
|
}
|
|
```
|
|
|
|
## Navigator scoped ViewModel
|
|
|
|
Voyager 1.1.0-beta01 also have introduced the support for Navigator scoped ViewModel and Lifecycle.
|
|
This will make easy to share a ViewModel cross screen of the same navigator.
|
|
|
|
```kotlin
|
|
class MyScreen : Screen {
|
|
@Composable
|
|
fun Content() {
|
|
val myViewModel = navigatorViewModel { MyScreenViewModel() }
|
|
}
|
|
}
|
|
```
|
|
|
|
## Lifecycle KMP
|
|
|
|
This version also brings the Lifecycle events for Screen lifecycle in KMP, now is possible to
|
|
a generic third party API that listen to Lifecycle of a Screen in KMP.
