Nice explanation… and I loved the part of the PersistentList, even when it wasn’t the scope of the tutorial, you nailed it with that explanation. Hope you can make a tutorial migrating from shared preferences to proto datastore. Thanks phillip

In common situations where you just need to save a few app settings, Data Store implemented this way is Ok. The only "thing" with this implementation is that it's killing the performance benefits of protocol buffers. The JSON conversion is slow, kotlin-serialization library is faster than Gson, but, it's still slow, if I'm not mistaken it uses reflection which is expensive. In the case you need to access many registries in short periods of time (perhaps transferring data to/from server) using the serialization library on top of protocol buffers would be a mistake. In other words, protocol Buffers is a faster alternative to JSON so using JSON objects in a protocol buffer would be a performance problem.

Can you make a video on how to actually use the protobuf files? I'm going to use the method you are showcasing for the time being because the alternative was too difficult for me

Hmm.. I also have error: kotlinx.serialization.SerializationException: Class 'SmallPersistentVector' is not registered for polymorphic serialization in the scope of 'PersistentList'. Mark the base class as 'sealed' or register the serializer explicitly. With the data classes: @Serializable data class ShoppingCart( val productsList: PersistentList = persistentListOf() ) @Serializable data class ShoppingCartItem( val id: String = "", val size: String = "" )

Struggling with this as well. Seems to be an issue with PersistentList and kotlin immutable collections or even kapt apparently. Have you managed to fix the error?

Hello guys, I'm trying to play it around and my code looks like this private suspend fun setLanguage(language: Language) { dataStore.updateData { it.copy( language = language, knownLocations = it.knownLocations.mutate { locationList -> locationList.add(Location(lat = 12345678.600, lng = 25664125.641)) }) } } is there anyone here try to save the list of Location and got an error like "kotlinx.serialization.SerializationException: Class 'SmallPersistentVector' is not registered for polymorphic serialization in the scope of 'PersistentList'. Mark the base class as 'sealed' or register the serializer explicitly." How can I soleve this error, Thank you in advance
