And React has that "web development" ecosystem taint... I'd definitely lean towards Flutter in this case. It's neat, tidy and a contained ecosystem. It may not be fully perfect, but for cross platform UI's I think it's the way to go.
My only question is - say if one uses Rust, is flutter_rust_bridge the way to go?
flutter_rust_bridge is what rustdesk uses with pretty good success, it's where I first discovered it.
Ah, I love rustdesk. I didn't know it was Flutter based. Only minor complaint about Rustdesk is that when you send the official link to people, they are frightened by a big scary "Scammer" alert[1]. To you and me, we immediately understand its actual purpose, but to non technical folks they hesitate to click it. I've seen this too many times.
