-/**
- * [EventHandler] is responsible for handling events bound using on-* syntax
- * (i.e. `on-click="ctrl.doSomething();"`). The root of the application has an
- * EventHandler attached as does every [Component].
- *
- * Events bound within [Component] are handled by EventHandler attached to
- * their [ShadowRoot]. All other events are handled by EventHandler attached
- * to the application root ([Application]).
- *
- * **Note**: The expressions are executed within the closest context.
- *
- * Example:
- *
- *     <div foo>
- *       <button on-click="ctrl.say('Hello');">Button</button>;
- *     </div>
- *
- *     @Component(selector: '[foo]', publishAs: ctrl)
- *     class FooController {
- *       say(String something) => print(something);
- *     }
- *
- * When button is clicked, "Hello" will be printed in the console.
