使用flutter_webview_plugin dialog侧边划出控件均被webview遮住

webview被遮挡 无法现在webview的上方 如下图 阴影部分就是对话框弹出了 被Webview遮住

No file, test, platform, or reproduction steps are named. Start by reproducing the dialog and side-swipe control layering problem in the Flutter/native WebView integration, then trace how those elements are attached relative to the WebView. Done means the dialog and controls render above the WebView in the affected setup, with a regression check if the repository has a suitable test.
