FlutterJNI 的作用就是架起 Android 端Java与 Flutter Engine C/C++ 端的一座接口桥梁。为了方便 JNI 接口的管理,这里将所有的 JNI 接口都封装在了 FlutterJNI 里,方便使用 大部分FlutterJNI中的调用都与特定的“platform view”相关,而“platform view”的数量可能会很多。所以,在执行了attachToNative方法后,每个Fl...
handleFlutterMessage这个回调函数有两个参数:FlutterMethodCall接收Flutter传过来的方法名method和参数arguments, FlutterResult可以返回调用的结果,例如result(1)就给Flutter返回了1这个结果。 获取到FlutterMethodCall的方法名和参数后就可以进行处理了,我们以play为例: 根据url初始化播放内容,然后开始进行播放; 通过player....
在Flutter页面中注册后,调用post方法就可以调用对应的Java实现: loadData: (callback) async { Map<String,dynamic>data= await post("home/groups");if(data==null) { callback(false);return; } _data = AllCategoryResponse.fromJson(data);if(_data ==null|| _data.code !=0) { callback(false);...
可以发现,整个流程中都是机器码的传递,而 JNI 的通信又和 JavaVM 内部通信效率一样,整个流程通信的流程相当于原生端的内部通信。但是也存在瓶颈。我们可以发现,methodCall 需要编解码,其实主要的消耗都在编解码上了,因此,MethodChannel 并不适合传递大规模的数据。
removeCallbacks(runnable); eventHandler = null; count = 0; eventChannel = null; System.out.println("StreamHandler - onCanceled: "); } } ); result.success(true); } 定时器 private final Runnable runnable = new Runnable() { @Override public void run() { int TOTAL_COUNT = 50; if (...

经过表达式的堆叠,实现了语句,经过语句的堆叠实现了 body,再补充上形参和返回值,则就构成了我们运行时中的自定义方法 FlapFunction。这里要用到一下仿真函数的概念,FlapFunction 要实现 call 方法,这样在外部调用时就真的和 Function 画风一致了。 动态化页面运行时,Flap 会维持一套作用域体系。Scope 的结构相当于...
Microphone switcher ->callKeep.setMutedCall(uuid, true / false) Then you handle the action: Future<void>answerCall(CallKeepPerformAnswerCallActionevent)async{print('CallKeepPerformAnswerCallAction ${event.callUUID}');// notify to your call P-C-M the answer action};Future<void>endCall(CallKeep...
