Flutter - Webview_plugin - I can't enable full screen with video
You can try my plugin flutter_inappbrowser (EDIT: it has been renamed to flutter_inappwebview).
An example with a youtube video is presented below:
...child: InAppWebView( initialUrl: "https://www.youtube.com/watch?v=sPW7nDBqt8w", initialHeaders: {}, initialOptions: InAppWebViewWidgetOptions( inAppWebViewOptions: InAppWebViewOptions( debuggingEnabled: true, ) ), onWebViewCreated: (InAppWebViewController controller) { webView = controller; }, onLoadStart: (InAppWebViewController controller, String url) { }, onLoadStop: (InAppWebViewController controller, String url) { },),...
