ios - 如何将响应从 swift 传递给 Flutter？

Question

我正在尝试使用方法通道在颤振应用程序中设置支付集成，并且它在 android 平台上运行良好。但在 iOS 平台上，我无法将响应部分发送到颤振。付款成功后，我在“qpResponse”功能中收到响应，我该如何将其传递给颤振？

 extension AppDelegate {

    func linkNativeCode(controller: FlutterViewController,args: [String: Any?]) {
    
        return SetQpaymentDetails(controller: controller,args: args)
    
    }

   func SetQpaymentDetails(controller: FlutterViewController,args: [String: Any?])  {
    
    self.qpRequestParams?.gatewayId = ""
    self.qpRequestParams?.secretKey = ""
    self.qpRequestParams?.name = args["name"] as? String
    self.qpRequestParams?.address = args["address"] as? String
    self.qpRequestParams?.city = args["city"] as? String
    self.qpRequestParams?.state = args["state"] as? String
    self.qpRequestParams?.country = args["country"] as? String
    self.qpRequestParams?.email = args["email"] as? String
    self.qpRequestParams?.currency = args["currency"] as? String
    self.qpRequestParams?.referenceId = args["referenceId"] as? String
    self.qpRequestParams?.phone = args["phone"] as? String
    self.qpRequestParams?.amount = Double(args["amount"] as! String)! 
    self.qpRequestParams?.mode = args["mode"] as? String
    self.qpRequestParams?.productDescription = args["description"] as? String
    
    self.qpRequestParams?.sendRequest()
    
   }

  func qpResponse(_ response: NSDictionary) {
                        print("Response Inside customer app:",response)
                //Perform your actions with the response  
  
   }

 }

 qPayChannel.setMethodCallHandler({
     (call: FlutterMethodCall, result: @escaping FlutterResult) -> Void in
     
       if call.method == "payment" {

         guard let args = call.arguments else {
           return
         }
         if let myArgs = args as? [String: Any] {
    
            self.linkNativeCode(controller: controller,args: myArgs)
            
            
         } else {
           result(FlutterError(code: "-1", message: "iOS could not extract " +
              "flutter arguments in method: (sendParams)", details: nil))
         }
       } else if call.method == "getPlatformVersion" {
         result("Running on: iOS " + UIDevice.current.systemVersion)
       } else {
         result(FlutterMethodNotImplemented)
       }
  
   })
