一：传递数据

flutter：

iOS端接收消息：

AppDelegate.swift 中：

        let controller = self.window.rootViewController

        let channel = FlutterMethodChannel.init(name: "ksapp", binaryMessenger: controller as! FlutterBinaryMessenger)

        channel.setMethodCallHandler { (call, result) in

            self.resultChannel = result

            if call.method == "sendToiOS" {

               //做一些处理

               //。。。。。。

            }

        }

        GeneratedPluginRegistrant.register(with: self)

        return super.application(application, didFinishLaunchingWithOptions: launchOptions)

安卓端接收消息：

MainActivity.kt 中：

iOS主动发起消息：

    lazy var messageChannel:FlutterBasicMessageChannel  = {

        let navigation = UIApplication.shared.keyWindow?.rootViewController as? UINavigationController

        guard let contoller = navigation?.viewControllers.first as? FlutterViewController else {

            fatalError("contoller is not type FlutterViewController")

        }

        let channel = FlutterBasicMessageChannel(name: "iostoflutter", binaryMessenger: contoller.binaryMessenger,codec: FlutterJSONMessageCodec.sharedInstance());

        return channel

    }()

        messageChannel.sendMessage("datadatadata")

flutter接收消息：

二、页面跳转

        let controller = self.window.rootViewController

        self.navigationComtroller = UINavigationController.init(rootViewController: controller!)

        window = UIWindow(frame: UIScreen.main.bounds)

        window.rootViewController = self.navigationComtroller

        self.navigationComtroller?.delegate = self

        window.makeKeyAndVisible()

        let channel = FlutterMethodChannel.init(name: "ksapp", binaryMessenger: controller as! FlutterBinaryMessenger)

        channel.setMethodCallHandler { (call, result) in

            self.resultChannel = result

            if call.method == "sendToiOS" {

                //获取当前位置

                let kspage = KSMapController()

                kspage.block = {newstr in

                    print(newstr)

                    result(newstr)

                }

                self.navigationComtroller?.pushViewController(kspage, animated: true)

            }

        }

        GeneratedPluginRegistrant.register(with: self)

        return super.application(application, didFinishLaunchingWithOptions: launchOptions)

    }

    func navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) {

        //flutter页面需要隐藏导航

        navigationController.navigationBar.isHidden = viewController.isKind(of: FlutterViewController.self)

    }
