如何取消选中当我使用Material Angular选中另一个mat- using toggle时取消选中mat-slide toggle

<mat-slide-toggle [(ngModel)]="toggle1Value">Toggle 1</mat-slide-toggle>
<mat-slide-toggle (change)="toggle2Change($event)">Toggle 2</mat-slide-toggle>

toggle1Value: boolean = true;

toggle2Change(event: MatSlideToggleChange) {
  if (event.checked) {
    this.toggle1Value = false; // 取消选中Toggle 1
  }
}

<mat-slide-toggle (change)="toggle1Change($event)">Toggle 1</mat-slide-toggle>
<mat-slide-toggle #toggle2 (change)="toggle2Change($event)">Toggle 2</mat-slide-toggle>

import { MatSlideToggle } from '@angular/material/slide-toggle';
import { ViewChild } from '@angular/core';

@ViewChild('toggle2') toggle2: MatSlideToggle;

toggle1Change(event: MatSlideToggleChange) {
  if (event.checked) {
    this.toggle2.toggle(); // 取消选中Toggle 2
  }
}

toggle2Change(event: MatSlideToggleChange) {
  // do something
}
