How to add a component programmatically in Angular.Dart?

The API has changed in AngularDart 0.9.9:

• BlockFactory now is ViewFactory
• scope.$new now seems to be scope.createChild(scope.context)
• injector.createChild(modules) now requires a list of modules (instead of a single one)

AngularDart 0.10.0 introduces these changes:

• NgShadowRootAware not is ShadowRootAware
• ..value() now is ..bind(., toValue: .)

So the code of pavelgj now looks like so:

class AppComponent extends ShadowRootAware {
  Compiler compiler;
  Injector injector;
  Scope scope;
  DirectiveMap directives;

  AppComponent(this.compiler, this.injector, this.scope, this.directives);

  void onShadowRoot(ShadowRoot shadowRoot) {
    DivElement inner = shadowRoot.querySelector("#inner");
    inner.appendHtml("<inner-comp></inner-comp>");    
    ViewFactory template = compiler([inner], directives);
    Scope childScope = scope.createChild(scope.context);
    Injector childInjector = 
        injector.createChild([new Module()..bind(Scope, toValue: childScope)]);
    template(childInjector, [inner]);
    }
  }

This would be a proper use of the block API.

class AppComponent extends NgShadowRootAware {
  Compiler compiler;
  Injector injector;
  Scope scope;
  DirectiveMap directives;

  AppComponent(this.compiler, this.injector, this.scope, this.directives);

  void onShadowRoot(ShadowRoot shadowRoot) {
    DivElement inner = shadowRoot.querySelector("#inner");
    inner.appendHtml("<inner-comp></inner-comp>");    
    BlockFactory template = compiler([inner], directives);
    Scope childScope = scope.$new();
    Injector childInjector = 
        injector.createChild(new Module()..value(Scope, childScope));
    template(childInjector, [inner]);
  }
}

Also, if you ever need to recompile the inner template make sure you do childScope.$destroy() on the previous childScope.

The above code samples on longer work because of changes in the Angular Dart library. Specifically ViewFactory.call which no longer takes an injector but takes a Scope and a DirectiveInjector. I've tried adapting what's above and I get very close. The component shows up but none of the bindings are replaced (I see {{cmp.value}} for example.

Here's the code I'm using. I think the issue here is that DirectiveInjector is coming in as null.

void main() {
  IBMModule module = new IBMModule();
  AngularModule angularModule = new AngularModule();

  Injector injector = applicationFactory()
  .addModule(module)
  .run();

  AppComponent appComponent = injector.get(AppComponent);
  appComponent.addElement("<brazos-input-string label='test'/>");
}

@Injectable()
class AppComponent {
  NodeValidator validator;
  Compiler _compiler;
  DirectiveInjector _injector;
  DirectiveMap _directiveMap;
  NodeTreeSanitizer _nodeTreeSanitizer;
  Scope _scope;

  AppComponent(this._injector, this._compiler, this._directiveMap, this._scope, this._nodeTreeSanitizer) {
    validator = new NodeValidatorBuilder.common()
                      ..allowCustomElement("BRAZOS-INPUT-STRING")
                      ..allowHtml5()
                      ..allowTemplating();
  }

  void addElement(String elementHTML) {
    DivElement container = querySelector("#container");
    DivElement inner = new DivElement();
    inner.setInnerHtml(elementHTML, validator: validator);
    ViewFactory viewFactory = _compiler.call([inner], _directiveMap);
    Scope childScope = _scope.createChild(new PrototypeMap(_scope.context));
    if (_injector == null) {
      print("injector is null");
    }
    View newView = viewFactory.call(childScope, _injector);
    container.append(inner);
    newView.nodes.forEach((node) => inner.append(node));
  }
}


class IBMModule extends Module {
  IBMModule() {
    bind(BrazosInputStringComponent);
    bind(BrazosTextAreaComponent);
    bind(BrazosButtonComponent);
    bind(ProcessDataProvider, toImplementation: ActivitiDataProvider);
    bind(AppComponent);
  }
}
