Is there a deadline when Kotlin Synthetics is going to go from deprecated to removed? Or any official place it is being specifically stated?

You can read about that here:

Thanks. Ok, so after/during September this year synthetic are going to be unusable at all on future versions if I understand correctly.

I believe Kotlin Synthetics will still work after September if you don’t upgrade Kotlin to 1.4.20 or later. But is recommended to replace them with viewbinding which is not a hard task to do. You can read more about that here:

Thank you. Seems like a none option if the cost is to permanently block newer kotlin versions. So will migrate soon rather than later.

I believe that is for the best yeah! 😉 Good luck with that! 😄 💪

Also, another due date for Android developers regarding app bundles. That one is more urgent than synthetics.

Yeah, That is really important. Most likely Google are going to require even existing to converted next year to be able to update.
