Have you looked into Flutter? It uses Dart and can compile to native apps for android, ios, windows, Mac, Linux, and web.
After I saw your note, I had a quick catchup on that project.
It looks awesome, with the promise of mobile and desktop, and the ability to make apps that can be uploaded to the AppStore. Plus its Dart which is a pretty well structured language. Its ticking a lot of boxes…
Then I ran « wc -l » on my support libraries (i.e. not UI code) - 64k LoC that would need to be rewritten in dart. But then I noticed Flutnet. its probably an abomination linking the two… but it could be promising.
Thanks for the pointer.
