Unable to change preferred country

[egilsd]

Im trying to set the preferred country depending on what i get back from the ip address. Im checking the users IP in the afterViewInit to get the country the user is in. Im trying to set that country as the preferred country for the ngx-mat-intl-tel-input component instead of hardcoding it in. Any suggestions as to how to make that possible?

I tried making an observable and async it, but that doesnt seem to work here unfortunately.

Unfortunately current implementation doesn't accept any on-changes handler for an input property preferredCountries. I guess in such case the only way is to fire ChangeDetectorRef once you have the new set of countries ready.

@pavlikxor ChnageDetectorRef does not work

To set preferredCountriesInDropDown and/or selectedCountry is working

export class MuchbetterComponent {
      @ViewChild('phone') phoneElement!:NgxMatIntlTelInputComponent;

       //.... 

      setCountry(country:string) {
           const iso2 = country.toLowerCase();
          const foundCountry = this.phoneElement.allCountries.find(n => n.iso2 == iso2);
          if(foundCountry)
          {
            this.phoneElement.preferredCountriesInDropDown = [foundCountry];
            this.phoneElement.selectedCountry = foundCountry;
          }
      }

}
