Latest ddc (v.1.23.0 sdk) changed the way they translate properties. They now declare a different symbol for each prop and use that to store and retrieve the actual value inside the object, than declaring property getters and setter for it.
Polymer2.x seams to have problems with that because it want's to declare its own property getters and setters in order to implement property effects. There's a wa for this that needs to be injected in polymer-dart components in order to make it work again.
