bug(iOS): transitionStart is not triggered for anything but default navigation

[hirbod]

Description

transitionStart is never reported for presentation modes other than the default. When switching to modal or transparentModal, it only reports transitionEnd. When closing the modal, it reports both transitionStart and transitionEnd.

If the target is pushed normally, it works correctly. This bug occurs only on iOS, not on Android. Open the snack with iOS and check the logs. I have added two buttons, both pushing to the same screen. Only the default one triggers both start and end, while the modal one only emits the end.

Steps to reproduce

Open my Snack and watch the console while testing both buttons.

transitionStart and transitionEnd should work for every presentation mode.

Same issue applies to useTransitionProgress and useReanimatedTransitionProgress by the way.

Hey, @hirbod! Thanks for reporting the issue.
It should be fixed in react-navigation 6.10.0 by this PR react-navigation/react-navigation#11803.
If you're still having problems with this, please open a separate issue with reproduction steps.

[hirbod]

@maksg did you test my issue with the new update before blindly closing it? I have attached a Snack and all reproduction steps.

[maksg]

@hirbod Yes, we did test that with your example, it wasn't blindly closed. It was reproducible with the project you provided and the issue disappeared when we upgraded react-navigation to 6.10.0 in your sample.

Thank you very much. I think I misunderstood your reply, thanks a ton! ❤️

@maksg I've just confirmed that it's working!
