I would kinda even prefer Go. Learning Dart is really specific to Flutter, I wouldn't end up using it for anything else. Go is kinda useful.

I have played with Flutter before and liked it, but was annoyed about the lack of what are now called PlatformViews. I might give it another shot now.

I just wish I could consume it from a different language, Go, TypeScript.... C# even Kotlin. I don't love learning a language for a single purpose if I can help it.
