Dart 并发处理之Isolate

Isolate 隔离运行

import 'dart:async';
import 'dart:isolate';

/// 隔离处理函数
/// 顶级函数或类的静态方法
void handler(SendPort sendPort)
{
      sendPort.send('I am Tom: '+sendPort.hashCode.toString());
}

void main() 
{
    var receivePort = ReceivePort();
    var sendPort    = receivePort.sendPort;

    await Isolate.spawn(handler, sendPort);

    sendPort.send('I am Gim!'+sendPort.hashCode.toString());

    //方式一 事件流订阅者
    receivePort.listen((target){
         print('Receive message: '+target.toString());
    });
    
    // 方式二 绑定处理函数
    receivePort.forEach((target){
        print('Receive message: '+target.toString());
    });

    // 方式三 流的方式读取
    await for(var target in receivePort) {
       print('Receive message: '+target.toString());
    }
}
