Hi,
I have tried your branch in my project and that build error disappears. Unfortunately I can not still build my project because there are other plugins affected by the same problem...

Hi,
Can you share your build error?

Hi,

your fix works on my project.
What I wrote is to highlight that this update to Flutter 3.29 caused the same problem for other plugins too.
This is an interesting article that describes what has happened with this new flutter version: https://benamorn.medium.com/today-i-learned-after-upgrading-to-flutter-3-29-0-7c7ab1a97975.

Anyway, here is an excerpt of my build error with open_file_plus plugin (https://pub.dev/packages/open_file_plus):
