Flutter 3.22 breaks package in release mode

[christofkost]

Hello and thank you very much for this great package! It is definitely the best tree package in the Flutter World.
But with Flutter 3.22 the update behaviour of checkboxes is not properly working anymore when executing app in release.
This is probably related to this issue regarding keys: flutter/flutter#148983

We had to downgrade our app from Flutter 3.22 to 3.19. Now it is working again.
Would it be possible to make this project compatible with Flutter 3.22.x in release build?
