feat: Allow custom/angular navigation on swipe to go back

Feature Request

Ionic version: [x] 4.12.0

Describe the Feature Request The swipe to go back feature is tightly coupled to the NavController. I guess this is the culprit. Since ionic 4 it seems to be the preferred way to directly use angular’s router for navigation (see e.g. here). So it would be nice to have a bit more control over this navigation event.

Describe Preferred Solution Maybe one could pass the swipeHandler on the directive. Something like:

// template
<ion-router-outlet [swipeHandler]="getSwipeHandler()"></ion-router-outlet>

// controller
getSwipeHandler() {
  return {
    canStart: () => { .. },
    onStart: () => { .. },
    onEnd: () => { .. }
  };
}

One downside of this approach would be that one would have to take care of animations oneself.

Describe Alternatives One could also disable this feature, expose swiper and implement this feature oneself. But this seems a bit cumbersome.

Additional Context This is primarily relevant for iOS.

Hi Liam,

I just wanted you to know that I’m still here. Just didn’t have the time yet to create a sample repo. Hopefully I will be able to do it at latest next week. Sorry about that.

Cheers!
