Flutter: How to animate between pages with BottomNavigationBar

I'm building an app with multiple pages. There are going to be some common elements. I want to wrap them in Hero() widgets so that they animate from one screen to another.
The problem is that the bottom navigation bar cuts between widgets. The way I currently have it is that I have a Home() widget that has a Scaffold(). The scaffold has a body which returns a widget (different pages) and a BottomNavigationBar(). Is there a way I can make a route be inside of the home's body widget or to add a route animation to the bottom navigation bar or other solutions that could fix this problem?
I don't want to have to make each page have a bottom navigation bar of it's own and route between them and I'd prefer to have the bottom navigation bar inside of the parent widget. How can I achieve this?
Thanks for your help!
I fixed it by having to put a bottom navigation bar in each page. I made it simpler by making a widget for it that takes in the page index so that I can just code it once and just put the widget on each page and write it's index.

How do I synchronise Silver Appbar scroll with the list view builder inside it in Flutter

Actually, I'm using a Silver AppBar in Flutter and inside it, I'm using a ListView Builder that has its own scroll. So basically there are two scrolls. But when I scroll List View Builder, Silver AppBar doesn't scroll. I want both of them to scroll from anywhere. What do I do?
Use sliver list istead of list view the problem will solve
here is the link of widget : https://api.flutter.dev/flutter/widgets/SliverList-class.html
You can put NeverScrollableScrollPhysics as a scroll physics for ListView.builder, so AppBar will scroll as with the content, maybe this is what you are looking for.
