CORE_DIRECTIVES = const [NgClass, NgFor, NgIf, NgTemplateOutlet, NgStyle, NgSwitch, NgSwitchWhen, NgSwitchDefault]

A collection of Angular core directives that are likely to be used in each and every Angular application.

This collection can be used to quickly enumerate all the built-in directives in the directives property of the @Component annotation.

Example

Instead of writing:

import 'package:angular/common.dart'
    show
        NgClass,
        NgIf,
        NgFor,
        NgSwitch,
        NgSwitchWhen,
        NgSwitchDefault;
import 'my_directives.dart' show OtherDirective;

@Component(
    selector: 'my-component',
    templateUrl: 'my_component.html',
    directives: const [
      NgClass,
      NgIf,
      NgFor,
      NgSwitch,
      NgSwitchWhen,
      NgSwitchDefault,
      OtherDirective
    ])
class MyComponent {
  ...
}

One could import all the core directives at once:

import 'angular/common.dart' show CORE_DIRECTIVES;
import 'my_directives.dart' show OtherDirective;

@Component(
    selector: 'my-component',
    templateUrl: 'my_component.html',
    directives: const [CORE_DIRECTIVES, OtherDirective])
class MyComponent {
  ...
}
