Does this need to be published? I think observable is sufficient.

In case you didn't already know this:

@reflectable (no longer necessary but keeps a symbol around for mirrors).
@observable - (implies @reflectable) a property which we will reference in {{ }}
expressions that we want to auto updated.
@published - (implies @observable) a property settable from html, e.g.:
<class-view retainedBytes="77"></class-view>

True. Thanks for clarifying!

   ClassViewElement.created() : super.created();
 
   Future<ServiceObject> eval(String text) {
     return cls.isolate.get(
         cls.id + "/eval?expr=${Uri.encodeComponent(text)}");
   }
 
   // TODO(koda): Add no-arg "calculate-link" instead of reusing "eval-link".
-  Future<ServiceObject> retainedSize(String dummy) {
-    return cls.isolate.get(cls.id + "/retained");
+  Future<ServiceObject> retainedSize(var dummy) {
+    return cls.isolate.get(cls.id + "/retained")

Maybe add a .get to Class:

cls.get('retained');

Done.

+        .then((ServiceMap obj) {
+          retainedBytes = int.parse(obj['valueAsString']);
+        });
   }
 
   void refresh(var done) {
     cls.reload().whenComplete(done);
   }
 }
