And for customize icon in the navigation bar, just put the icons you want in the CustomNavigationBarItem like this.

CustomNavigationBar(
        ...
        items: [
          CustomNavigationBarItem(
            icon: Icons.home,
          ),
          CustomNavigationBarItem(
            icon: Icons.shopping_cart,
          ),
          CustomNavigationBarItem(
            icon: Icons.lightbulb_outline,
          ),
          CustomNavigationBarItem(
            icon: Icons.search,
          ),
          CustomNavigationBarItem(
            icon: Icons.account_circle,
          ),
        ],
        ...
      )

Attention: If you set isFloating to true, I would recommand you to set extendBody to true in Scaffold for a better performance.
