I did; but it makes no sense. That's like saying "Why does Dart even both having classes"?. If you're writing a client application, you probably have data structures. Some of those data structures you need to send to the server (or receive). When you write code that interacts with those structures, you want code-completion; static analysis, etc.; that's kinda the point of Dart's typing!
