My `value class`wrapping `String`always causes parameter to be `unstable`(as per `plugin:androidx.compose.compiler.plugins.kotlin:metricsDestination`option), even though https://issuetracker.google.com/issues/144582214 is

fixed

, so it should be inferred as stable. Can I somehow make it became stable?

I have even tried to mock Composes internal apis:

@Immutable
@JvmInline
@StabilityInferred(0)
value class Wrapper(@Stable val value: String) {
    companion object {
        @JvmField
        public val `$stable` = 0
    }
}

but with no luck.

Is your value class declared in a module that has the compose compiler enabled? I think the auto inferring only happens in the modules that are using compose.

It is generally in separate module (but it has compose plugin). I have moved in the the same module (with compose) that uses it and it's still unstable.

The issue you referenced seems limited to primitive types.

String

is not a primitive type. You could create a new issue requesting a more general solution.

I've helped you out: https://issuetracker.google.com/issues/234050608
