Siva, wasn't there some common flag all the implementations were meant to
introduce? Dart 2 preview or such?

Yes preview_dart_2 but that would also include a whole slew of other stuff like
turning on the Dart front end, kernel etc.

Maybe for now we can keep this under an experimental flag and when things
stabilize include it under preview_dart_2.
