What steps will reproduce the problem?
- Create any angular component
- Add '#example' to any tag in your template, making it a template reference variable
- Use @ViewChild('example') to reference said element
What is the expected result?
Not showing a message that the template reference variable is unused.
What happens instead?
The template reference variable is reported as 'unused local variable'
Please provide any additional information below.
Component:
import { Component, ViewChild, ViewContainerRef } from '@angular/core';
@Component( {
selector: 'some-test',
templateUrl: './test.component.html',
styleUrls: []
} )
export class TestComponent {
@ViewChild( 'example', { read: ViewContainerRef } ) set dynamicRef( example: ViewContainerRef ) {
console.log( 'example was updated: ', example );
};
constructor() {
}
}
Template:
<div>
<ng-container *ngIf="true">
<div #example> <!-- #example is reported as `Unused local variable example` -->
</div>
</ng-container>
</div>
It seems to be a quite isolated use case:
- removing the *ngIf makes it being recognized as 'used'
- removing the <div>, making the ng-container the root element, makes it being recognized as 'used'
