忘了更新这个:/如果您查看问题中链接的代码
隔离日志/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
如果你这样做,你只能发送原语而不是期货,基本上就是这样
