Question about inheritance and parameters

import kotlinx.serialization.Serializable

@Serializable
abstract class TagsDto( val id: String?, val name: String, val icon: String?, val color: String? )

@Serializable
class LocationTagsDto( id: String? = null, name: String, icon: String?, color: String? )
    : TagsDto( id = id, name = name, icon = icon, color = color)

This fails compilation on the second @Serializable

This class is not serializable automatically because it has primary constructor parameters that are not properties

I don’t want to have LocationTagsDto add any new property to TagsDto. How can I make this work? Thanks in advance.

One option "without" a super constructor:

import kotlinx.serialization.Serializable

@Serializable
abstract class TagsDto {
    abstract val id: String?
    abstract val name: String
    abstract val icon: String?
    abstract val color: String?
}

@Serializable
data class LocationTagsDto(
    override val id: String? = null, 
    override val name: String, 
    override val icon: String?, 
    override val color: String? 
) : TagsDto()

Thank you, didn’t know about the override keyword
