Next page has back button on top bar

After walkthrough finishes, a new page is loaded but with a back button at top (appBar). Are there any ways to hide or remove that button?

I think it can be related in how next page is called internally. I assume if it's called as `Navigator.pushReplacementNamed("some Route");` it should be fixed
