 Animated icons are now supported in `PersistentBottomNavBarItem`. You will need to define and use an `AnimationController` and `Animation<double>` for it to work. Following is an example.
 
-    ```dart
 
-        final _animationController =  AnimationController(vsync: this, duration: const Duration(milliseconds: 400));
-        final _animationValue = Tween<double>(begin: 0.toDouble(), end: 1.toDouble()).animate(_animationController),
 
-        final item = PersistentBottomNavBarItem(
-            icon: AnimatedIcon(
-            icon: AnimatedIcons.home_menu,
-            progress: _animationValue,
-            ),
-            iconAnimationController: _animationController,
-            title: "Home",
-            activeColorPrimary: Colors.blue,
-            activeColorSecondary: _navBarStyle == NavBarStyle.style7 || _navBarStyle == NavBarStyle.style10 ? Colors.white : null,
-            inactiveColorPrimary: Colors.grey,
