HarmonyOS 鸿蒙Next 是否有类似小红书从feed流进详情页的一镜到底的特效的示例

可参照官方示例对Navigation添加customNavContentTransition自定义转场：

https://gitee.com/openharmony/docs/blob/master/zh-cn/application-dev/reference/apis-arkui/arkui-ts/ts-basic-components-navigation.md#示例3

添加后每次转场时都会走这个函数，返回undefined的话则走默认的navigation左右转场，返回NavigationAnimatedTransition类型对象的话则走对应的自定义转场动画实现。因此在customNavContentTransition函数中需要自行添加路由管控，基本方式是对from.name和to.name以及是否注册了转场动画实现等进行判断，来决定是否走自定义转场。

参考代码:

Navigation(this.pageInfos)
  .hideNavBar(true)
  .customNavContentTransition((from: NavContentInfo, to: NavContentInfo, operation: NavigationOperation) => {
    if ((!from || !to) || (!from.name || !to.name)) {
      return undefined;
    }

    // 通过from和to的name对自定义转场路由进行管控
    if (!this.isCustomTransitionEnabled(from.name, to.name)) {
      return undefined;
    }

    // 针对点击按钮A走自定义转场点击按钮B走默认转场的场景，需要对是否注册了animation进行判断，来决定是否走自定义转场
    let fromParam: AnimateCallback = CustomTransition.getInstance().getAnimateParam(from.index);
    let toParam: AnimateCallback = CustomTransition.getInstance().getAnimateParam(to.index);
    if (!fromParam.animation && !toParam.animation) {
      return undefined;
    }

    // 一切判断完成后，构造customAnimation给系统侧调用，执行自定义转场动画
    let customAnimation: NavigationAnimatedTransition = {
      onTransitionEnd: (isSuccess: boolean) => {
        console.log(TAG, `current transition result is ${isSuccess}`);
      },
      timeout: 1000,
      transition: (transitionProxy: NavigationTransitionProxy) => {
        console.log(TAG, 'trigger transition callback');
        if (fromParam.animation) {
          fromParam.animation(operation == NavigationOperation.PUSH, true, transitionProxy);
        }
        if (toParam.animation) {
          toParam.animation(operation == NavigationOperation.PUSH, false, transitionProxy);
        }
      }
    };
    return customAnimation;
  })
