Well I haven't seen anyone mention Flet, which is pleasant (if maybe not all that complete) if you have Dart/Flutter experience, so increment your counter at least one. :-)
First time I've seen this, looks really cool! Thanks for sharing it!
was about to mention this, I plan to also try a small project in flet to see how it works. I have done flutter/dart before, but was not so enthused about the dart experience.
