CustomBottomNavBar class

A customizable bottom navigation bar that manages navigation between different pages.

The CustomBottomNavBar widget provides a styled bottom navigation bar that allows users to switch between various pages in the app. It integrates seamlessly with a PageView to handle page transitions and maintains the selected index state.

Example usage:

List<NavigationItem> navItems = [
  NavigationItem(
    page: HomePage(),
    icon: Icon(Icons.home),
    label: 'Home',
  ),
  NavigationItem(
    page: SearchPage(),
    icon: Icon(Icons.search),
    label: 'Search',
  ),
  NavigationItem(
    page: ProfilePage(),
    icon: Icon(Icons.person),
    label: 'Profile',
  ),
];

CustomBottomNavBar(
  items: navItems,
  backgroundColor: Colors.white,
  selectedItemColor: Colors.blue,
  unselectedItemColor: Colors.grey,
  elevation: 10.0,
  type: BottomNavigationBarType.fixed,
);
