在flutter webview中隐藏Url引用

Question

我正在开发我的 webview 应用程序，并且正在使用 webview_flutter 包。我的目标是为用户显示特殊的视频内容，但我不希望他们看到网址。在 iOS 上，当您单击并按住列表中的一个视频时，会弹出许多不同的选项（在 safari 中打开链接、共享、复制链接等）。我想知道是否可以隐藏所有 url 和来自用户的 url 相关操作？否则我的 WebView 工作正常。

谢谢

你可以使用包https://pub.dev/packages/flutter_inappbrowser
要解决问题，请临时参考主分支

flutter_inappwebview:
