{
public HybridWebViewRenderer() : this(new WKWebViewConfiguration())

    public HybridWebViewRenderer(WKWebViewConfiguration config) : base(config)
    {
        config.AllowsInlineMediaPlayback = true;
        userController = config.UserContentController;
        var script = new WKUserScript(new NSString(JavaScriptFunction), WKUserScriptInjectionTime.AtDocumentEnd, false);
        userController.AddUserScript(script);
        userController.AddScriptMessageHandler(this, "invokeAction");
    }

    protected override void OnElementChanged(VisualElementChangedEventArgs e)
    {

        if (e.OldElement != null)
        {
            userController.RemoveAllUserScripts();
            userController.RemoveScriptMessageHandler("invokeAction");
            GenericWebView hybridWebView = e.OldElement as GenericWebView;
