CustomBottomBar(
  selectedIndex: 0,
  handleChange: (index) => print('Selected: $index'),
  navItems: [
    NavigationItem(
      icon: Icons.home_outlined,
      selectedIcon: Icons.home,
      label: 'Home',
    ),
    NavigationItem(
      icon: Icons.search_outlined,
      selectedIcon: Icons.search,
      label: 'Search',
    ),
    NavigationItem(
      icon: Icons.notifications_outlined,
      selectedIcon: Icons.notifications,
      label: 'Alerts',
      badgeCount: 3,
    ),
  ],
)
