I was trying to use EventEmitter to emit custom events and to handle show/hide components in the AppComponent based on the menu item/link that was clicked in the header. In the parent component EventEmitter parameter value undefined for listener.
I was trying to learn and implement @Input and @Output decorators in Angular. And when I tried @Output, I got the following error Cannot find name ‘Output’ in Angular.
I am getting the following error EventEmitter Error: Expected 0 type arguments, but got 1 in Angular.
