如何在angular formBuilder中设置一周后的日期？

import { FormBuilder, FormControl } from '@angular/forms';

constructor(private formBuilder: FormBuilder) { }

dateControl: FormControl;

ngOnInit() {
  this.dateControl = this.formBuilder.control(new Date(Date.now() + 7 * 24 * 60 * 60 * 1000));
}

<form [formGroup]="myForm">
  <input type="date" formControlName="dateControl">
</form>
