Because webviewx_plus >=0.5.1+1 depends on webview_flutter_android ^3.16.1 and youtube_player_iframe 5.2.1 depends on webview_flutter_android ^4.0.2, webviewx_plus >=0.5.1+1 is incompatible with youtube_player_iframe 5.2.1.
Are chance you can upgrade to support youtube_player_iframe 5.2.1?
Many Thanks
