description: "A [android.view.View] that can host Jetpack Compose UI content. Use [setContent] to supply the
content composable function for the view.

By default, the composition is disposed according to [ViewCompositionStrategy.Default]. Call
[disposeComposition] to dispose of the underlying composition earlier, or if the view is never
initially attached to a window. (The requirement to dispose of the composition explicitly in the
event that the view is never (re)attached is temporary.)

[ComposeView] only supports being added into view hierarchies propagating [LifecycleOwner] and
[SavedStateRegistryOwner] via [androidx.lifecycle.setViewTreeLifecycleOwner] and
[androidx.savedstate.setViewTreeSavedStateRegistryOwner]. In most cases you will already have it
set up correctly as [androidx.activity.ComponentActivity], [androidx.fragment.app.Fragment] and
[androidx.navigation.NavController] will provide the correct values."

A `android.view.View` that can host Jetpack Compose UI content. Use `setContent` to supply the
content composable function for the view.

By default, the composition is disposed according to `ViewCompositionStrategy.Default`. Call
`disposeComposition` to dispose of the underlying composition earlier, or if the view is never
initially attached to a window. (The requirement to dispose of the composition explicitly in the
event that the view is never (re)attached is temporary.)

`ComposeView` only supports being added into view hierarchies propagating `LifecycleOwner` and
`SavedStateRegistryOwner` via `androidx.lifecycle.setViewTreeLifecycleOwner` and
`androidx.savedstate.setViewTreeSavedStateRegistryOwner`. In most cases you will already have it
set up correctly as `androidx.activity.ComponentActivity`, `androidx.fragment.app.Fragment` and
`androidx.navigation.NavController` will provide the correct values.


## Functions

```kotlin
fun setContent(content: @Composable () -> Unit)
```


Set the Jetpack Compose UI content for this view. Initial composition will occur when the
view becomes attached to a window or when `createComposition` is called, whichever comes
first.
