Hi everyone,

Do you know if there is a way to add a default type for sealed class serialization or any discussion regarding this somewhere?

Imagine that you have two Styles (default and dark):

@Serializable
sealed class Style {

   @SerialName("default")
   object Default : Style()

   @SerialName("dark")
   class Dark(...) : Style()
}

Now in order to future-proof the above in case new styles are introduced, we want to use the Default style in case a new type (“light” f.x.) is introduced.
Is there some idiomatic way to do this - besides using a custom serializer?

Custom serializer I think

this is what i do: https://github.com/edenman/kmpPlayground/blob/master/shared/src/commonMain/kotlin/chat/quill/data/OneOfSerializer.kt

(you have an object Unknown : Style() and then pass that into OneOfSerializer(Style.class, Style.Unknown)
