我在我的页面上有一个表单,当我调用FormGroup.reset()它时将表单类设置为ng-pristine ng-untouched但FormControl.hasError(...)仍然返回truthy.我在这做错了什么？

模板

<form [formGroup]="myForm" (ngSubmit)="submitForm(myForm)">
  <mat-form-field>
    <input matInput formControlName="email" />
    <mat-error *ngIf="email.hasError('required')">
      Email is a required feild
    </mat-error>
  </mat-form-field>
  <mat-form-field>
    <input matInput type="password" formControlName="password" />
    <mat-error *ngIf="password.hasError('required')">
      Password is a required feild
    </mat-error>
  </mat-form-field>
  <button type="submit">Login</button>
</form>

零件

export class MyComponent {
  private myForm: FormGroup;
  private email: FormControl = new FormContorl('', Validators.required);
  private password: FormControl = new FormControl('', Validators.required);

  constructor(
    private formBuilder: FormBuilder
  ) {
    this.myForm = formBuilder.group({
      email: this.email,
      password: this.password
    }); …
