CompositionLocalProvider

CompositionLocalProvider are used to provide a value for an CompositionLocal

How to provide a value for an CompositionLocal?

@Composable
private fun MyUserScreen() {
    val user = User("Jens", 31)
    CompositionLocalProvider(LocalActiveUser provides user) {
        UserInfo()
    }
}
Somewhere above in your hierarchy you have to use CompositionLocalProviders to provide a value for your CompositionLocal. You can provide the values of multiple CompositionLocals inside Providers. The syntax is: “CompositionLocal<T> provides T”. All child @Composable of CompositionLocalProvider will implicitly be able to get the value of the CompositionLocals.
