AngularDart v0.14.0 Error: Type 'xxx' not found in generated typeFactory maps when run pub server

问题

I test my app on AngularDart v0.14.0 pub server but it has error

Exception: Uncaught Error: Type 'CurrencyService' not found in generated typeFactory maps. Is the type's constructor injectable and annotated for injection?
Stack Trace:

When run in localhost:3030 this error don't occur.

Here is my Module

class CERPModule extends Module {
...
    bind(CurrencyService);
...
}

Here is my CurrencyService

library cerp_currency_service;

import 'dart:async';
import 'dart:convert';
import 'package:angular/angular.dart';


class CurrencyService {
  Http _http;
  CurrencyService (Http this._http);
...
}

回答1:

As far as I know you need to add the @Injectable annotation to your CurrencyService class.

@Injectable()
class CurrencyService {
