颤振材料路线不'；t在本机iOS navigatorViewController上导航

我已经使用颤振部分的颤振方法通道调用打开了本机故事板UIViewController。现在我想使用iOS（swift）部分的方法调用导航到其他小部件/视图。 方法调用和路由部分没有问题，只有一个问题。我通过iOS代码中的invokeMethod从颤振部分导航到的新视图已包含在当前iOS视图中。这就是我从颤振方法“wait platform.invokeMethod（'Printy'）；”打开的iOS UIViewController下的新颤振导航小部件。我想在当前iOS UIViewController上导航

AppDelegate.swift

@objc class AppDelegate: FlutterAppDelegate {
    var navigationController: UINavigationController?
    var CHANNEL: FlutterMethodChannel?
    
    override func application(
        _ application: UIApplication,
        didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
    ) -> Bool {
        let controller = window.rootViewController as! FlutterViewController
        CHANNEL = FlutterMethodChannel(name: "com.flutter.epic/epic", binaryMessenger: controller as! FlutterBinaryMessenger)
        CHANNEL?.setMethodCallHandler { [unowned self] (methodCall, result) in
            if methodCall.method == "Printy" {
                self.newViewController(result)
            }
        }

        GeneratedPluginRegistrant.register(with: self)
        
        navigationController = UINavigationController(rootViewController: controller)
        navigationController?.isNavigationBarHidden = true
        window?.rootViewController = navigationController
        window?.makeKeyAndVisible()
        
        return super.application(application, didFinishLaunchingWithOptions: launchOptions)
    }
    
    func newViewController(_ result: @escaping FlutterResult) {
        let storyboard : UIStoryboard? = UIStoryboard.init(name: "Main", bundle: nil);
        let window: UIWindow = ((UIApplication.shared.delegate?.window)!)!
        let paytmTransactionController = storyboard!.instantiateViewController(withIdentifier: "PaytmTransactionController") as! PaytmTransactionController
        paytmTransactionController.result = result
        self.navigationController?.pushViewController(paytmTransactionController, animated: true)
    }
}

PaytmTransactionController.swift

class PaytmTransactionController: UIViewController {
    var result: FlutterResult?
    
    override func viewDidLoad() {
        super.viewDidLoad()

    }
    
    @IBAction func close(_ sender: Any) {
        self.navigationController?.popViewController(animated: true)
    }
    
    @IBAction func showFlutterView(_ sender: Any) {
        self.navigationController?.popViewController(animated: true)
        (UIApplication.shared.delegate as? AppDelegate)!.CHANNEL!.invokeMethod("didRecieveTranscript", arguments: nil)
    }
}

颤振->应用程序省道

final GlobalKey<NavigatorState> navigatorKey =
    new GlobalKey<NavigatorState>();

@override
void initState() {
  super.initState();

  final channelName = 'com.flutter.epic/epic';
  final methodChannel = MethodChannel(channelName);
  methodChannel.setMethodCallHandler(this._didRecieveTranscript);
}

Future<void> _didRecieveTranscript(MethodCall call) async {
  final String utterance = call.arguments;
  switch (call.method) {
    case "didRecieveTranscript":
      openMyProject(utterance);
      break;
    case "didRecieveNativeViewFactory":
      didRecieveNativeViewFactory(utterance);
      break;
  }
}

Future<void> didRecieveNativeViewFactory(utterance) async {
  navigatorKey.currentState
      .pushNamed("/project", arguments: ScreenArguments());
}

Future<void> openMyProject(utterance) async {
  navigatorKey.currentState
      .pushNamed("/project", arguments: ScreenArguments());
}

@override

}经过两天的探索，我找到了一个解决方案。很简单，只需调用“SystemNavigator.pop（）”即可从颤振端弹出iOS路由
