This is the source code for my article:
In this example each tab has its own navigation stack. This is so that we don’t lose the navigation history when switching tabs.
This is a very common use case for a lot of apps.
How is it built?
- Create an app with a
Scaffold
and aBottomNavigationBar
. - In the
Scaffold
body, create aStack
with one child for each tab. - Each child is an
Offstage
widget with a childNavigator
. - Don't forget to handle Android back navigation with
WillPopScope
.
