FlutterMethodChannel 使用 注iOS 端简单设置
class HYFlutterNavChannel: NSObject {objc public static let share HYFlutterNavChannel()// 声明 FlutterMethodChannelvar channel: FlutterMethodChannel// lazy var map: [String: (_ call: FlutterMethodCall, _ result: FlutterResult) - Void] {return [pop:pop,]}()override init() {// name 一定需要和 flutter里面约定好保持一致channel FlutterMethodChannel.init(name: Flutter/navigation, binaryMessenger: FlutterBoost.instance().engine().binaryMessenger)super.init()channel.setMethodCallHandler {[weak self] (call, reslt) inlet method self?.map[call.method]method?(call, reslt)}}objc public static func start() {_ HYFlutterNavChannel.share}// popfunc pop(call: FlutterMethodCall, result: FlutterResult) {UINavigationController.topNavigationController()?.navigationController?.popViewController(animated: true)}}在iOS 注册Flutter 引擎的地方使用
// 案例是放到 AppDelegate中
[FlutterBoost.instance setup:application delegate:delegate callback:^(FlutterEngine *engine) {NSLog(FlutterBoost 开始操作);// 使用 MethodChannel[HYFlutterNavChannel start];[HYFlutterCommonChannel start];}];上述就把iOS端使用FlutterMethodChannel简单进行通信集成完毕。
Flutter 端 MethodChannel 集成与使用
import dart:collection;import package:flutter/services.dart;class NavigationChannel {// 这里需要和原生保存一致 Flutter/navigation// ignore: constant_identifier_namesstatic const MethodChannel channel_navigation MethodChannel(Flutter/navigation);// ignore: non_constant_identifier_namesstatic final channel_navigation_handlers HashMapString, MethodCallHandler();NavigationChannel() {init();}void init() {channel_navigation_handlers[nativeQuitFlutter] nativeQuitFlutter;channel_navigation.setMethodCallHandler((call) async {channel_navigation_handlers[call.method]?.call(call);});}// native 提供的功能方法Futurevoid finishHostPage() async {return channel_navigation.invokeMethod(pop);}Futurevoid nativeQuitFlutter(MethodCall call) async {}// -------------flutter提供的功能-----------------void registerInitRoute(MethodCallHandler handler) {channel_navigation_handlers[initRoute] handler;}
}typedef MethodCallHandler Futuredynamic Function(MethodCall call)?;以上 Flutter MethodChannel 集成完毕
Flutter 使用MethodChannel 这里使用了一个类进行统一管理 通信类
import package:my_flutter/common_channel.dart;import navigation_channel.dart;class Channels {// ignore: empty_constructor_bodiesChannels._() {}// 注册 Channelstatic final navigation NavigationChannel();static final common CommonChannel();
}
在Flutter使用的地方进行调用
Channels.navigation.finishHostPage();上述完成flutter就可以调用原生里面注册的pop方法了。
