Just updated Confetti to use Kotlin 1.9.0-Beta + some related dependencies (ksp plugin + compose compiler). Everything seems to work ok though if I do try to enable experimental K2 compiler I'm seeing some errors but haven't had chance to look in to those yet.

./gradlew assemble -Pkotlin.experimental.tryK2=true

@Arkadii Ivanov just fyi in case these ring a bell

There should be the kotlin-parcelize plugin doing the job. Not sure if it's compatible with K2.

[John O'Reilly]

seems others have seen this but not clear what the fix was in this case https://youtrack.jetbrains.com/issue/KT-53651

[John O'Reilly]

btw also posted here https://kotlinlang.slack.com/archives/C03PK0PE257/p1684944687842889

[Arkadii Ivanov]

Yeah, that issue references another issue (https://youtrack.jetbrains.com/issue/KT-53590) which is marked as fixed in 1.8.20. Weird.
