What is the best way to prevent executing a method in [queryParams] in Angular 7?

I'm currently working on incorporating the option for users to open a link in a new tab. I'm trying to avoid using the (click) method, so I've come up with the following logic to achieve this:

<a [routerLink]="['/search/' + search.id]" [queryParams]="getQueryParams()">Destination</a>

The issue I'm facing is that the getQueryParams() function is being called every time, causing the app to slow down significantly. Is there a way to avoid calling this method every time? Additionally, I'm also open to exploring alternative methods to implement the open in a new tab functionality without relying on the (click) event?

Why is it necessary to retrieve the queryParams using a function?

If not, you have the option of manually assigning the queryParams to a public property within your component and connecting it to the queryParams property of the link.

Component:

  public queryParams;

  ngOnInit(){
    this.queryParams = this.getQueryParams();
  }

HTML: 

<a [routerLink]="['/search/' + search.id]" [queryParams]="queryParams">Destination</a>
