Angular2 Dart Analysis Plugins

Annotation analysis in Dart files

Build models for @Directive and @Component annotations:
- Parse selector.
- Build inputs.
- Report problems for invalid selectors, unresolved input setters, etc.
Build models for @View annotations:
- Resolve templateUrl argument.
- Validate that specified directives are valid directive class literals.
Resolve inline @View templates in Dart files.
Resolve external @View templates referenced from Dart files in context of specified directives and view class members.

Templates resolution is implemented only partially. Currently the following feature are done.

Resolve element tags to @Component selectors.
Resolve of attribute names in forms name, [name], bind-name, (event), on-event to corresponding inputs and events.
Resolve expressions in interpolations like <div>{{user.name}}</div>.
Resolve expressions in bound inputs like <text-panel [text]='user.name'>.
Support for the template attribute <div template='ng-if items.isNotEmpty'>Has items</div>.

To provide information for DAS clients the server_plugin plugin contributes several extensions.

Angular analysis errors are automatically merged into normal errors notifications for Dart and HTML files.
Navigation extension contributes navigation regions:
- In external HTML templates.
- In inline templates in Dart files.
- In Dart annotations:
  - navigation from templateUrl to the corresponding HTML files.
  - navigation from input declarations to setters, e.g. to text in inputs: const ['text: my-text'].
Occurrences extension reports regions where every Dart element or an input is used in a Dart or HTML file. So, clients of DAS can highlight all of the whe user select one.
