> Dart is a really _ugly_ language with lots of tiny annoyances. Its as if someone took worst parts of Java and Javascript and turned them into a language. Terrible to write, terrible to read, terrible to use.

While I’m a bit ambivalent towards Flutter, I totally disagree with you on Dart. To me it’s a better version of Java/Typescript with a very mature cross-platform and JIT/AOT compiler. Admittedly there are some things I wish they would take from TS (like discriminated unions), and I haven’t tried “modern” Java either so maybe that’s improved, but even so, I rarely feel like Dart is getting in the way.

They probably just haven't used the latest Dart versions which fixed a lot of the "ugliness" (which I'd call pragmatism but regardless) like primary constructors where a class can just be a single line now.

And I mean, their entire comment is a way to shill their app so I wouldn't take much stock in what they're saying.
