Hi, I'm having trouble with properties in expect value classes.

I'm trying to create a multiplatform Color class, backed by Compose's Color class in the jvm target.

// android module
actual typealias Color = androidx.compose.ui.graphics.Color

Compose Color class contains getter for color components.

// Compose's Color class
@kotlin.jvm.JvmInline
value class Color(val value: ULong) {
    
    val red: Float
        get() {
           ...
        }
}

I would like to put these getters into my expected Color class and can't seem to find the correct syntax that would allow me to do it (see the attached image).

not sure if that can be fixed easily, but an alternative is to expect extension properties for red, blue etc

You could also define those properties in an interface and have Color extend that interface. The actual definitions would then have to implement them.
