It is a pitty, because when you are navigating in a slider and you press the back button, what you are usually expecting is moving to the previous slide, not closing the app.
I’m trying to do the same thing. I’m trying to use a multi step form kind of a process and the back button is just wrong for the slider when used this way.
I may end up just calling the same page/component with an updated parameter and push it to the nav stack to get the same basic concept. I just wish that the navbar didn’t animate while the content did. Plus having the other options for the swiping/sliding would be nice.
