Using the parcelize plugin with K2 doesn't allow a parceler for a nullable type (🧵 )

[eygraber]

import android.os.Parcel
import kotlinx.parcelize.Parceler
import kotlinx.serialization.json.Json
import kotlinx.serialization.json.JsonArray
import kotlinx.serialization.json.JsonObject

object JsonObjectParceler : Parceler<JsonObject?> {
  @Suppress("EXPERIMENTAL_API_USAGE")
  override fun create(parcel: Parcel) =
    parcel.readString()?.let(Json::parseObject)

  override fun JsonObject?.write(parcel: Parcel, flags: Int) {
    parcel.writeString(this?.toString())
  }
}

object JsonArrayParceler : Parceler<JsonArray?> {
  @Suppress("EXPERIMENTAL_API_USAGE")
  override fun create(parcel: Parcel) =
    parcel.readString()?.let(Json::parseArray)

  override fun JsonArray?.write(parcel: Parcel, flags: Int) {
    parcel.writeString(this?.toString())
  }
}

Usage:

data class Venue(override val json: @WriteWith<JsonObjectParceler> JsonObject) : JsonObjectWrapper, Parcelable

Error:

Parceler type JsonObjectParceler is incompatible with kotlinx/serialization/json/JsonObject
