Dart2JS and Enumerators

Question

I'm using enumerators (experimental) in my project. Pub Build (Generate JS) in my Dart Editor does not work due to the enums. In my console, this command:

dart2js file.dart --enable-enum

does work, but it is inconvinient to do it through the console. Is there any way to add arguments to the default command in Dart Editor (--enable-enums) so it'd allow it to compile into JS?

Running it by default in Dartium works and when copying and pasting the server url (http://localhost:8080/index.html), the dart2js is triggered and it starts working (after average compilation time).

EDIT: Yes, I have enums enabled in my editor.

EDIT2: To enable enums in dart2js, I have this transformer in pubspec.yaml:

transformers:
- $dart2js:
    commandLineOptions: [--enable-enum]

However, I get this error in a file, which uses enums:

Directive not allowed here.
part of thing;
^^^^^^^^^^^^^^^^
[Info from Dart2JS]:

It's weird that it works in the console with the same arguments and not in the editor.

I have filled a bug report here.

Is your enum defined in a part file? Is dart2js the last transformer in your pubspec.yaml transformer section? — Günter Zöchbauer
Yes. The enum is defined in a part, but dart2js transformer is the only one, is it's the last one. — Vilda
Why are you using --enable-enums (plural) on command line and --enable-enum (singular) in the pubspec.yaml transformer config. I think it should be the same (singular on both) code.google.com/p/dart/issues/detail?id=21823#c3 — Günter Zöchbauer

As of 2016, the enumerators are fully implemented.
