Additional context
Add any other context about the problem here.
Hey! Unfortunately it is hard to support old and new Flutter versions, sometimes they change APIs and introduce new things. What you see is how it should be coded since stable 3.16. Is it possible for you to update your Flutter version? you seem so specific to be on 3.13.9 is there something after that that blocks you?
