Dart is a pretty nice language, and practically speaking I don't think it's "weaker" (optionally typed) system is a concern. The vast majority of Dart libraries are typed, giving you all of the benefits (compile time type checking, runtime type checks, intellisense, etc.) Check out the flutter project (http://flutter.io http://flutter.io) for a hint of what Dart on Android and iOS looks like.
