I think it is totally fair to criticize Dart as any other language. I am criticizing Dart as a language which was purely designed and enforced rather than organically chosen by community.
Even more, I cannot ignore all the improvements made in recent years, though I think it is the biggest evidence of pure initial design. I think version 3 looks promising and one day i might ignore everything I complained about, right now I will stay with my opinion even though I respect yours.
