创建 FlutterEngine 和 FlutterViewController
appdelegate中didFinishLaunchingWithOptions方法增加：
_fEngine = [[FlutterEngine alloc] initWithName:@"xxxxxx.flutterengine"];//唯一就行
[_fEngine run];//默认执行main.dart 也可以指定flutter入口(flutter 项目中要对应，否则会报错)
测试Native调用Flutter,(模拟从native跳转flutte页面)
FlutterViewController *fvc = [[FlutterViewController alloc] initWithProject:nil initialRoute:@"/detail/1234567" nibName:nil bundle:nil];
return fvc;
"/detail/1234567"是flutter的一个路由，123456是参数
测试Flutter调用Native,(模拟从flutte页面返回native页面)
FlutterViewController *fvc = [[FlutterViewController alloc] initWithProject:nil initialRoute:@"/detail/1234567" nibName:nil bundle:nil];
FlutterMethodChannel * messageChannel = [FlutterMethodChannel methodChannelWithName:@"xxxxxx.flutter" binaryMessenger:fvc];
[messageChannel setMethodCallHandler:^(FlutterMethodCall * _Nonnull call, FlutterResult _Nonnull result) {
NSLog(@"flutter call native：\n method=%@ \n arguments = %@",call.method,call.arguments);
if ([call.method isEqualToString:@"dismiss"]) {
if (result) {
// 回掉给flutter
result(@"flutter view dismiss");
}
[fvc.navigationController popViewControllerAnimated:YES];
}
}];
return fvc;
Flutter侧实现
onPressed: (){
// 和native交互-返回
MethodChannel(MethodChannelName).invokeMethod('dismiss','').then((value) {});
},
Flutter路由实现
class Routers {
static String root = "/";
static String detailPage = "/detial/:id";
static void configureRouter(FluroRouter router) {
router.notFoundHandler = Handler(
handlerFunc: (BuildContext context, Map<String, List<String>> params) {
return UnKnownPage();
},
);
// detailPage路由页面配置
router.define(detailPage, handler: detailHanderl);
}
路由使用随便，上面用的是Fluro
- 以上是 MethodChanel的交互，还有两种 EventChannel和MessageChannel的交互后面再续*
