Attention

If you update from version under 0.6.0, there are some breaking changes in the version 0.6.0. The icon in CustomNavigationBarItem has changed from IconData to Widget.

old version

CustomNavigationBarItem(
      {@required this.icon,
      IconData selectedIcon,
      this.selectedTitle,
      this.unSelectedTitle,
      this.badgeCount = 0,
      this.showBadge = true})
      : selectedIcon = selectedIcon ?? icon;

  ///
  /// The icon of the item
  /// Typically the icon is an [Icon].
  ///
  final IconData icon;

new version

CustomNavigationBarItem(
      {@required this.icon,
      Widget selectedIcon,
      this.title,
      Text selectedTitle,
      this.badgeCount = 0,
      this.showBadge = false})
      : selectedIcon = selectedIcon ?? icon,
        selectedTitle = selectedTitle ?? title;

  ///
  /// The icon of the item
  /// Typically the icon is an [Icon].
  ///

  final Widget icon;

You can customize these attributes in the navigation bar.

`scaleFactor`	`double`	scale factor for the icon scale animation.	0.2
`elevation`	`double`	The z-coordinate of this CustomNavigationBar	8.0
`items`	`List`	item data in CustomNavigationBar	required
`selectedColor`	`Color`	[Color] when [CustomNavigationBarItem] is selected	[blueAccent]
`unSelectedColor`	`Color`	[Color] when [CustomNavigationBarItem] is not selected.	grey[600]

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

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

CustomNavigationBar(
        ...
        items: [
          CustomNavigationBarItem(
          icon: Icon(Icons.home),
          title: Text("hello"),
        ),
        CustomNavigationBarItem(
          icon: Icon(Icons.shopping_cart),
        ),
        CustomNavigationBarItem(
          icon: Icon(Icons.lightbulb_outline),
        ),
        CustomNavigationBarItem(
          icon: Icon(Icons.search),
        ),
        CustomNavigationBarItem(
          icon: Icon(Icons.account_circle),
        ),
        ],
        ...
      )

If you want add notification badge, just use like this

CustomNavigationBar(
        ...
        items: [
        CustomNavigationBarItem(
          icon: Icon(Icons.home),
          badgeCount: _badgeCounts[0],
          showBadge: _badgeShows[0],
        ),
        CustomNavigationBarItem(
          icon: Icon(Icons.shopping_bag),
          badgeCount: _badgeCounts[1],
          showBadge: _badgeShows[1],
        ),
        CustomNavigationBarItem(
          icon: Icon(Icons.lightbulb_outline),
          badgeCount: _badgeCounts[2],
          showBadge: _badgeShows[2],
        ),
        CustomNavigationBarItem(
          icon: Icon(Icons.search),
          badgeCount: _badgeCounts[3],
          showBadge: _badgeShows[3],
        ),
        CustomNavigationBarItem(
          icon: Icon(Icons.account_circle),
          badgeCount: _badgeCounts[4],
          showBadge: _badgeShows[4],
        ),
      ],
        ...
      )

To clear a badge, set showBadge to false

If you want add title under icon, just use like this

CustomNavigationBar(
      iconSize: 30.0,
      selectedColor: Color(0xff040307),
      strokeColor: Color(0x30040307),
      unSelectedColor: Color(0xffacacac),
      backgroundColor: Colors.white,
      items: [
        CustomNavigationBarItem(
          icon: Icon(Icons.home),
          title: Text("Home"),
        ),
        CustomNavigationBarItem(
          icon: Icon(Icons.shopping_cart),
          title: Text("Cart"),
        ),
        CustomNavigationBarItem(
          icon: Icon(Icons.lightbulb_outline),
          title: Text("Explore"),
        ),
        CustomNavigationBarItem(
          icon: Icon(Icons.search),
          title: Text("Search"),
        ),
        CustomNavigationBarItem(
          icon: Icon(Icons.account_circle),
          title: Text("Me"),
        ),
      ],
      currentIndex: _currentIndex,
      onTap: (index) {
        setState(() {
          _currentIndex = index;
        });
      },
    );
