Hi, I ran your example but got an error, can you see what could be the reason?

The Dart version I compiled is:

Good question. I haven't tried with Dart 3 yet, I wonder if something changed, I'll take a look.

Looks like it's actually a change in 2.19. I'm looking into what changed and see if I can have a workaround.

Thanks for letting me know!

@arcticfox1919 I've updated the code to work with 2.19+ and tested against tags/2.19.5. This is due to eliminating the native keyword (see the ticket mentioned above.)

@fuzzybinary Thank you very much for your reply！
