Flutter bottom Navigation bar with Routes-CodePudding

I want to navigate through pages using routes and Navigator.pushNamed() on a Bottom Navigation Bar. Here, I'm using a FlashyTab bar for aesthetics. To be more specific, pressing each of the icons on the navigation bar should take me to a different page, and I want to implement this using routes.

  @override
  Widget build(BuildContext context) {
    Size size = MediaQuery.of(context).size;
    return Scaffold(
      bottomNavigationBar: FlashyTabBar(
        animationCurve: Curves.linear,
        selectedIndex: _selectedIndex,
        showElevation: true,
        onItemSelected: (index) => setState(() {
          _selectedIndex = index;
        }),
        items: [
          FlashyTabBarItem(
            icon: const Icon(Icons.account_box),
            title: const Text('Challenger'),
          ),
          FlashyTabBarItem(
            icon: const Icon(Icons.phone),
            title: const Text('Contact'),
          ),
          FlashyTabBarItem(
            icon: const Icon(Icons.dashboard_rounded),
            title: const Text('Events'),
          ),
          FlashyTabBarItem(
            icon: const Icon(Icons.badge),
            title: const Text('Quick Scan'),
          ),
        ],
      ),

      body: 

    );
  }

CodePudding user response：

In your screen define this

List<Widget> pageList = [
    const ChallengerScreen(),
    const ContactScreen(),
    const EventsScreen(),
    const QuickScanScreen(),
  ];

In body use it like this

return Scaffold(
      bottomNavigationBar: FlashyTabBar(
        animationCurve: Curves.linear,
        selectedIndex: _selectedIndex,
        showElevation: true,
        onItemSelected: (index) => setState(() {
          _selectedIndex = index;
        }),
        items: [
          FlashyTabBarItem(
            icon: const Icon(Icons.account_box),
            title: const Text('Challenger'),
          ),
          FlashyTabBarItem(
            icon: const Icon(Icons.phone),
            title: const Text('Contact'),
          ),
          FlashyTabBarItem(
            icon: const Icon(Icons.dashboard_rounded),
            title: const Text('Events'),
          ),
          FlashyTabBarItem(
            icon: const Icon(Icons.badge),
            title: const Text('Quick Scan'),
          ),
        ],
      ),
//you have to just do changes here...
    body:pageList.elementAt(_selectedIndex)

    );

You don't need to use Navigator.pushNamed() it not the right method to do.
