Ionic 4, logout method

Ionic Framework
1

Hi guys, I was wondering what would be a nice implementation of a logout method, specifically which method from the navCtrl would you use?

I have this example:

 logout() {
    console.log("Logging out user");
    this.service.logout();
    this.navCtrl.navigateRoot("/welcome");
  }

But there is no animation at all, the logout method from the authService is only removing the token from the storage. Should I use navigateBack? or implement a loading or something?
