AngularDart – A directive that implicitly adds a dependency directive?

Issue

Is it possible to have a directive that implicitly adds another dependency directive?

@Directive(selector: '[dirA]')
class DirectiveA {
  DirectiveA() { ... }
}

@Directive(selector: '[dirB]')
class DirectiveB {
  DirectiveB(DirectiveA a) { ... }
}

@Component(
     template: '<div dirA dirB></div>'
     //template: '<div dirB></div>' // this is the goal
)
class Foo {}

Solution

No, unfortunately. As you mentioned yourself, inheritance is an option.

For example:

@Directive(...)
class AutoSuggestedOptions {}

@Directive(...)
class AutoFormattedOptions extends AutoSuggestedOptions {}
