Description

Google recently introduced the Retain Api,

https://android-developers.googleblog.com/2025/12/whats-new-in-jetpack-compose-december.html

https://developer.android.com/reference/kotlin/androidx/compose/runtime/retain/package-summary#retain(kotlin.Function0)

this looks simple and easy to use.

the composition demo uses Viewmodel to handle the composition player , placedoverlays etc, Instead they can use the retain Api.

It will eliminate the need for the dependency injection, (which viewmodels may require), maintain the
Unidirectional Data Flow (UDF) pattern and will be easier to deploy.
