我正在创建一个flutter x native swift 5集成，我需要访问本地zendesk模块，好的，但是当我按下native zendesk中的关闭按钮时它无法返回flutter。我找不到像我的问题一样的东西，也许这是我调用视图的方式，它在调用本机后消除了所有颤振堆栈。

关闭按钮图片

我的 appDelegate.swift：

    import UIKit
    import Flutter
    import ZendeskSDK
    import ZendeskCoreSDK

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
    var homeHelpView: ZendeskNavigationController!
    override func application(
        _ application: UIApplication,
        didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        
        
        var homeHelpView: ZendeskNavigationController!
        let controller : FlutterViewController = window?.rootViewController as! FlutterViewController
        let batteryChannel = FlutterMethodChannel(name: "uzzo_native_channel",
                                                  binaryMessenger: controller.binaryMessenger)
        batteryChannel.setMethodCallHandler({
            [weak self] (call: FlutterMethodCall, result: FlutterResult) -> Void in
            guard call.method == "open_zendesk" else {
                result(FlutterMethodNotImplemented)
                return
            }
            
            let args = call.arguments as! Array<Any>
            
            Zendesk.initialize(appId: "xxxxxxxxxxxxxxxxx",
                               clientId: "xxxxxxxxxxxxxxx",
                               zendeskUrl: "xxxxxxxxxxxxxx")
            Support.initialize(withZendesk: Zendesk.instance)
            let identity = Identity.createAnonymous(name: (args[1] as! String), email: (args[0] as! String))
            Zendesk.instance?.setIdentity(identity)
            
            
            self?.window = UIWindow(frame: UIScreen.main.bounds)
            let config = RequestUiConfiguration()
            config.tags = ["ios"]
            let helpCenter = HelpCenterUi.buildHelpCenterOverviewUi()
            homeHelpView = ZendeskNavigationController(rootViewController: helpCenter)
            
            self?.window?.rootViewController = homeHelpView
            self?.window?.makeKeyAndVisible()
            
            
            
        })
        
        GeneratedPluginRegistrant.register(with: self)
        return super.application(application, didFinishLaunchingWithOptions: launchOptions)
    }
}

这是 ZendeskNavigationController.swift

import ZendeskSDK
import ZendeskCoreSDK
import UIKit

class ZendeskNavigationController: UINavigationController, UINavigationControllerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()

        let helpCenter = HelpCenterUi.buildHelpCenterOverviewUi(withConfigs: [])
        pushViewController(helpCenter, animated: true)
        self.navigationBar.shadowImage = UIImage()
       self.navigationBar.isTranslucent = true
        self.navigationBar.barTintColor = ConstantsColors.UZZOGreenColor
        self.navigationBar.backgroundColor = ConstantsColors.UZZOGreenColor
       self.navigationBar.titleTextAttributes = [
        NSAttributedString.Key.foregroundColor: UIColor.darkText,
        NSAttributedString.Key.font: UIFont.systemFont(ofSize: 28, weight: .heavy)]
        self.delegate = self
        self.navigationBar.backgroundColor = ConstantsColors.UZZOGreenColor
    }

}
