Is it possible to use stepper.reset() inside the ts file? I would like to do someting like
    onCheckRef() {
    if (this.refFormGroup.get('reference').invalid) {
      this.stepper.reset();
    } else {
      .....................
    }
  }
In the template :
<button mat-button (click)="onCheckRef()" matStepperNext>Valider</button>
