Need a persistent/same Bottom Navigation Bar for all screens - Flutter

Question

I am a beginner with flutter and dart. I have been trying to implement a navigationBar on three different pages in my app. The toggling works well for an individual

Answer 1

You can use IndexedStack to persist State when you touch/change the page

Scaffold(
  body: SafeArea(
    top: false,
    child: IndexedStack(
      //Permet de garder le state des vues même quand on change de vue
      index: _currentIndex,
      children: _children,
    ),
  ),
  bottomNavigationBar: BottomNavigationBar( items: [ ] ),
);
