Class
Common
```kotlin
@ExperimentalLayoutApi
class MutableWindowInsets(initialInsets: WindowInsets = WindowInsets(0, 0, 0, 0)) : WindowInsets
```
A `WindowInsets` whose values can change without changing the instance. This is useful to avoid
recomposition when `WindowInsets` can change.
Note: This API as experimental since it doesn't enforce the right consumption patterns.
## Properties
Common
```kotlin
var insets
```
The `WindowInsets` that are used for `left`, `top`, `right`, and
`bottom` values.
