CodePudding user response：

You just need two Scaffolds nested like this:

Scaffold(
  body: Scaffold(
    appBar: AppBar(),
    drawer: Drawer(),
  ),
  bottomNavigationBar: BottomNavigationBar(
    items: [
      BottomNavigationBarItem(icon: Icon(Icons.home), label: 'Home'),
      BottomNavigationBarItem(icon: Icon(Icons.person), label: 'Profile'),
    ],
  ),
)
