Remove a view from the back history - Ionic2

Question

Anyone knows how to remove a view from the back history (or navigation stack) in ionic2?

In Ionic 1 I solved this with

this.$ionicHistory.nextViewOptions({
  disableAnimate: true, 
  disableBack: true
});

Would be really useful, for example, to fully remove the login page of my application from the history once a successfully login was performed.

Just not showing the back button isn't enough in such case, since Android terminals got their own physical back button on the devices.

I tried, after my login function returned a successful promise and before pushing the next page in the stack:

this.navController.pop();

or

this.navController.remove(this.viewCtrl.index);

but unfortunately both weren't successful :(

obrejacatalin on the https://forum.ionicframework.com/t/solved-disable-back-in-ionic2/57457 found the solution

this.nav.push(TabsPage).then(() => {
  const index = this.nav.getActive().index;
  this.nav.remove(0, index);
});

so I guess it's important to push the next page first, wait for the promise answer and then remove the current view

To remove one backview you need to use startIndex and count of pages to remove from stack.

    this.navCtrl.push(NextPage)
    .then(() => {
      const startIndex = this.navCtrl.getActive().index - 1;
      this.navCtrl.remove(startIndex, 1);
    });
