如何重用使用MaterialPageRoute生成器创建的颤动视图？

class CustomPageRoute extends MaterialPageRoute {
  CustomPageRoute({WidgetBuilder builder, RouteSettings settings})
      : super(builder: builder, settings: settings);

  @override
  Widget buildTransitions(BuildContext context, Animation<double> animation,
      Animation<double> secondaryAnimation, Widget child) {
    // 在这里定义页面切换时的过渡效果
    // 返回一个动画效果的Widget，例如FadeTransition、SlideTransition等
    return FadeTransition(opacity: animation, child: child);
  }
}

Navigator.push(
  context,
  CustomPageRoute(builder: (context) => YourPage()),
);
