How to use volatile in Kotlin

Question

I tried something like this:

private volatile var instanceState: InstanceState = InstanceState.starts

Error:  'Expected member declaration'

and like this:

private volatile var instanceState: InstanceState = InstanceState.starts

Error:  'Property getter or setter expected'

Volatile not supported on Kotlin ?

Kotlin does not have a volatile keyword but an annotation: @Volatile (https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.jvm/-volatile/)
