AngularDart template not found - dart

Question

When working on my project in AngularDart, I created a component called LoginComponent:
// lib/component/login.dart
#Component(
selector: 'login',
templateUrl: 'login.html')
class LoginComponent {
String username;
String password;
}
In the same folder where I created the login.dart script, I also put it's template code:
<!-- /lib/component/login.html -->
<form ng-submit="login()">
<input type="text" placeholder="Username" ng-model="username" />
<input type="password" placeholder="Password" ng-model="password" />
<input type="submit" value="Submit" />
</form>
The project's structure looks as follows:
.
├── CHANGELOG.md
├── LICENSE
├── README.md
├── lib
│   ├── annotations.dart
│   └── component
│   ├── login.dart
│   └── login.html
├── pubspec.lock
├── pubspec.yaml
└── web
├── index.html
└── main.dart
I also added the html template to the angular transformer:
name: 'duseapp'
version: 0.0.1
description:
An absolute bare-bones web app.
environment:
sdk: '>=1.0.0 <2.0.0'
dependencies:
browser: any
web_components: ">=0.10.1 <0.11.0"
angular: ">=1.1.0 <2.0.0"
restpoint:
git: git://github.com/Adracus/restpoint.git
duse:
git: git://github.com/duse-io/duse-dart.git
transformers:
- angular:
html_files:
- lib/component/login.html
But now, I'm receiving the error:
Target of URI does not exist: 'login.html'
Does anybody know what's the cause of this?
For further insight, the github url of the project is here.
Thanks for your help.

Answer 1

After digging around for a day, I found an interesting post on Google Groups, which solved my problem (except for a little mistake, it is 'packages' instead of 'package'). According to the post, one should specify the templateUrl as follows:
templateUrl: 'packages/<package-name>/<any-lib-subdirectory>/<filename>'
That solved my problem.
