Use IndexedStack Widget

int _currentIndex = 0;

@override
  Widget build(BuildContext context) {
    return Scaffold(
      body: SafeArea(
        child: IndexedStack(
          index: _currentIndex,
          children: const [
            HomePage(),
            SettingsPage(),
          ],
        ),
      ),
      bottomNavigationBar: BottomNavigationBar(
        currentIndex: _currentIndex,
        onTap: (int index) => setState(() => _currentIndex = index),
        items: [
          BottomNavigationBarItem(icon: Icon(Icons.home), label: 'Home'),
          BottomNavigationBarItem(icon: Icon(Icons.settings), label: 'Settings'),
        ],
      ),
    );
  }
