android - 广播接收器未在接口对象内触发

Question

我正在使用颤振通道来本地跟踪呼叫。但是广播接收器没有被触发。

 override fun configureFlutterEngine(@NonNull flutterEngine: FlutterEngine) {
      super.configureFlutterEngine(flutterEngine)
      EventChannel(flutterEngine.dartExecutor.binaryMessenger, CHANNEL).setStreamHandler(
        object : EventChannel.StreamHandler {
            var eventSink: EventChannel.EventSink? = null
    
            override fun onListen(p0: Any?, sink: EventChannel.EventSink) {
                eventSink = sink
                val receiver = object : BroadcastReceiver() {
                  override fun onReceive(context: Context, intent: Intent) {
                      println("Receiver start from main")
                      eventSink?.success("Receiver start to channel")
                      eventSink?.success(ss)
              }
            }
          }
             override  fun onCancel(p0: Any?) {
                  eventSink = null
              }
            }
          
      )
  }
