EventChannel #

native 调 flutter #

swift实现 #

  1. 初始化FlutterViewController,FlutterEventChannel
  2. 实现FlutterStreamHandler子类,实现onListen(),onCancel()方法
  3. 调用eventChannel.setStreamHandler(XX),XX是第2步创建的子类

Dart代码 #

  1. 唤醒监听nativeMessageListener(),放在initState()里面,类似于一种声明
  2. 定义监听处理nativeMessageListener()方法,里面调用eventChannel.receiveBroadcastStream().listen(evnet),根据调过来的event(一般是字典,分别以方法名,参数等作为key)做相应处理。

没有flutter 调 native #
