I had this

abstract class AbstractResourceTopic(val state: ResourceState? = null, val isOn: Boolean? = null) {
    abstract val resourceType: ResourceType
}

and this

fun AbstractResourceTopic.getIcon(): Int {
    this.state?.let {
        return when (it.state) {
            0 -> getStateZeroIcon()
            1 -> getStateOneIcon()
            2 -> getStateTwoIcon()
            else  -> getStateZeroIcon()
        }
    }
    this.isOn?.let {
        return if (isOn) getOnIcon() else getOffIcon()
    }
    return getStateZeroIcon()
}

I turned into this

abstract class AbstractResourceTopic {
    constructor(state: ResourceState)
    constructor(isOn: Boolean)
    abstract val resourceType: ResourceType
}

and I don’t know how to create extension classes for this two different constructors

fun AbstractResourceTopic.getStateIcon(): Int {
        return when (it.state) {
            0 -> getStateZeroIcon()
            1 -> getStateOneIcon()
            2 -> getStateTwoIcon()
            else  -> getStateZeroIcon()
        }
    }
}
fun AbstractResourceTopic.getIsOnIcon(): Int {
    return if (isOn) getOnIcon() else getO
}

This is not working and I couldn’t find the correct syntax or if I can even do this

Your constructor parameters aren't properties
