Angular Dart component events

Question

I am trying to pass custom events from a component to its parent component/controller

confirm.html

Answer 1

This should be the same, just add a scope argument to the constructor so the component gets the scope injected.

There was a related change in Angular 0.14.0 https://github.com/angular/angular.dart/commit/181f01448555c475869505491159045904e5dc89

I haven't yet tried this. From the description you need to implement ScopeAware

@Component(...)
class MyComponent implements ScopeAware {
  Watch watch;
  MyComponent(Dependency myDep) {
    // It is an error to add a Scope / RootScope argument to the ctor and will result in a DI
    // circular dependency error - the scope is never accessible in the class constructor
  }

  void set scope(Scope scope) {
     // with this scope you should be able to use emit
     // This setter gets called to initialize the scope
     watch = scope.rootScope.watch("expression", (v, p) => ...);
  }
}
