Computed property not serialize

A data class with computed property:

data class Bean(val name: String) {
  val computed: String
    get() = "--$name"  
}

Use `kotlinx-serialization-runtime-0.20.0’:

val result = Json(Stable).stringify(Bean.serializer(), Bean(name = "rj"))

the result is {"name":"rj"} but I want it to be {"name":"rj","computed":"--rj"}. How?

I need this feature also.

Example use case: my image urls are computed and not stored in the database.

This is still open?
