飞镖/颤振：隔离的顶级功能的异步行为

忘了更新此：/如果您查看问题中链接的代码

isolates_logging / lib / provider / test_isolate.dart

  Future<void> _handle(int _m) async {    final response = ReceivePort();    isolateTest = await Isolate.spawn(_isolate, response.sendPort);    final sendPort = await response.first as SendPort;    final answer = ReceivePort();    sendPort.send([_m, answer.sendPort]);    await answer.first.then((p) {       _outbound.sink.add(p);});  }  static void _isolate(SendPort _initialReplyTo) {    final port =  ReceivePort();    _initialReplyTo.send(port.sendPort);    port.listen((message) {      final data = message[0] as int;      final send = message[1] as SendPort;      send.send(_syncHandle(data));    });  }}Future<String> _syncHandle(int data) async {  return 'done';}

注意send.send（_syncHandle（data））; 部分

如果这样做，则只能发送基元，而不能发送期货，基本上就是这样
