@sdeleuze @orangy Typically in my Dart projects, I don't have any JS code, last one that I pushed to production was about 200k LOC just Dart code, 0 LOC in JavaScript.
So I typically use Dart (and hopefully Kotlin in the future) as a JS replacement - current project might use one or two lines of interop, but otherwise already on 50k lines of Dart and about 50 lines of JavaScript which I'll probably just port to Dart.
