Documentation

You can customize these attributes in the navigation bar.

   ///
  /// height of the [CustomNavigationBar].
  ///
  /// use [defaultHeight] in [DefaultCustomNavigationBarStyle] when height is null.
  ///
  final double height;

  ///
  /// Item data in [CustomNavigationBarItem]
  ///
  final List<CustomNavigationBarItem> items;

  ///
  /// [Color] when [CustomNavigationBarItem] is selected.
  ///
  /// default color is [blueAccent].
  final Color selectedColor;

  ///
  /// [Color] when [CustomNavigationBarItem] is not selected.
  ///
  /// default color is [grey[600]].
  final Color unSelectedColor;

  ///
  /// callback function when item tapped
  ///
  final Function(int) onTap;

  ///
  /// current index of navigation bar.
  ///
  final int currentIndex;

  ///
  /// size of icon.
  /// also represent the max radius of bubble effect animation.
  final double iconSize;

  ///
  /// Background color of [CustomNavigationBar]
  ///
  final Color backgroundColor;

  ///
  /// stroke color.
  /// default is [Colors.blueAccent].
  final Color strokeColor;

  ///
  /// animation curve of bubble effect
  ///
  final Curve bubbleCurve;

  ///
  /// animation curve of scale effect
  ///
  final Curve scaleCurve;

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,
          ),
        ],
        ...
      )
