Hi, I am using flutter MSAL SSO with flutter_inappwebview and azure_flutter_authentication package to login to the app.

let viewController: UIViewController = UIViewController.keyViewController!
              let webviewParameters = MSALWebviewParameters(authPresentationViewController: viewController)
              webviewParameters.webviewType = .default

I am trying to open another application in webview by using flutter_inappwebview, so that there will be a silent log in using MSAL SSO option in iOS device. But its not working

InAppWebView(
                    key: webViewKey,
                    initialUrlRequest: URLRequest(url: Uri.parse(widget.url)),
                    initialOptions: options,
                    pullToRefreshController: pullToRefreshController,
                    onWebViewCreated: (controller) {
                      webViewController = controller;
                    },
                    onLoadStart: (controller, url) {
                      logger.d("printing webview controller type: " +
                          controller.runtimeType.toString());

                      setState(() {
                        this.url = url.toString();
                        urlController.text = this.url;
                        isLoading = false;
                      });
                    },
                    androidOnPermissionRequest:
                        (controller, origin, resources) async {
                      return PermissionRequestResponse(
                          resources: resources,
                          action: PermissionRequestResponseAction.GRANT);
                    },
                    shouldOverrideUrlLoading:
                        (controller, navigationAction) async {
                      var uri = navigationAction.request.url!;

                      if (![
                        "http",
                        "https",
                        "file",
                        "chrome",
                        "data",
                        "javascript",
                        "about"
                      ].contains(uri.scheme)) {
                        if (await canLaunch(url)) {
                          // Launch the App
                          await launch(
                            url,
                          );
                          // and cancel the request
                          return NavigationActionPolicy.CANCEL;
                        }
                      }

                      return NavigationActionPolicy.ALLOW;
                    },
                    onLoadStop: (controller, url) async {
                      pullToRefreshController?.endRefreshing();
                      setState(() {
                        this.url = url.toString();
                        urlController.text = this.url;
                      });
                    },
                    onLoadError: (controller, url, code, message) {
                      pullToRefreshController?.endRefreshing();
                    },
                    onProgressChanged: (controller, progress) {
                      if (progress == 100) {
                        pullToRefreshController?.endRefreshing();
                      }
                      setState(() {
                        this.progress = progress / 100;
                        urlController.text = this.url;
                      });
                    },
                    onUpdateVisitedHistory: (controller, url, androidIsReload) {
                      setState(() {
                        this.url = url.toString();
                        urlController.text = this.url;
                      });
                    },
                    onConsoleMessage: (controller, consoleMessage) {
                      print(consoleMessage);
                    },
                  ),

How to should I pass the login session from swift code to inappwebview in flutter? Please help me with this. I really appreciate it. Its working fine with android devices. The problem is from iOS devices.
