HarmonyOS鸿蒙Next中flutter打开web页面再跳转到视频播放页面会报错
HarmonyOS鸿蒙Next中flutter打开web页面再跳转到视频播放页面会报错 【问题描述】：目前使用webview_flutter 4.13.0_ohos和video_player-v2.10.0_ohos
测试发现如果打开web页面再跳转到视频播放页面会报错：
MissingPluginException(No implementation found for method listen on channel flutter.io/videoPlayer/videoEvents1)
不打开web页面不会触发这个问题，如果之前打开过web页面即使关闭了 再去打开视频播放也还是会有上述错误

本地flutter版本3.27.4，使用webview_flutter 4.13.0_ohos和video_player-v2.10.0_ohos 本地依赖时未复现报错问题；
开发者你好： 1、需要确认下你这边的两个插件是使用的线上依赖还是下载到本地依赖；
2、使用本地依赖场景是否会有问题。
在HarmonyOS Next中，Flutter通过PlatformView嵌入WebView后跳转视频页面报错，通常因WebView与视频播放器共用图形渲染通道冲突，或Flutter与Ark UI层生命周期管理不一致。需在跳转前显式销毁WebView（如调用webViewController?.clearCache()及dispose()），并确保视频播放使用原生Video组件而非Flutter插件。
