Fixing Android DataStore migration from a data object to a data class
I had to implement this migration for an object that was stored in DataStore using Protobuf and Kotlinx Serialisable on Android. The original object looked like this: @Serializable data class Assignment(val state: State) @Serializable sealed interface State { @Serializable data object Pending : State // More implementations } The new object was supposed to look like this: @Serializable sealed interface State { @Serializable data class Pending(val id: String) : State // More implementations }
