SuperTabs - selectedTab

Ionic Framework ionic-v3
1

hi,
In my app, I am using event to navigate between the pages and to throw messages. I want that if the user is on stage x he will start the application on stage x. can I use the same event for it? or should I use NavPush?
Thanks!

onTab(ev: any) {
    if (ev.index ==1 ) {
      let alert = this.alertCtrl.create({
        title: 'Next Stage',
        message: 'Are you sure you are ready?',
        buttons: [
          {
            text: 'No',
            handler: () => {
              this.superTabs.slideTo(this.selectedTab);
            }
          }, {
            text: 'Yes',
            handler: () => {
              this.selectedTab = ev.index;
              this.myStage=ev.index;
            }
          }
        ]
      });
      alert.present();
    } else {
      this.selectedTab = ev.index;
      this.superTabs.clearBadge(this.pages[ev.index].id);
    }
  }
