HarmonyOS 无感监听navDestinationUpdate的问题？

Question

https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-arkui-observer-V5\#observeronnavdestinationupdate

使用无感监听navDestinationUpdate时，callback的参数能否支持getConfigInRouteMap方法，能更便于拿取当前route\_map的配置信息

Answer 1

在router\_map.json中配置的data信息，可以通过onReady回调中执行ctx.getConfigInRouteMap()获取。详见：https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V5/arkts-navigation-navigation-0000001885999037-V5

路由拦截也能获取到NavDestinationContext
