所以Dart一样也是属于事件驱动,它也有自己的EventLoop. 3. EventLoop的组成 Dart的EventLoop事件循环和Javascript很类似,同样循环中拥有两个FIFO队列:「一个是事件队列(Event Queue),另一个就是微任务队列(MicroTask Queue)」 3.1 事件队列(Event Queue) 主要包含一些外部事件和Future,比如IO,绘制,手势以及Timer等事件...
Event Loop就像一个 infinite loop,被内部时钟来调谐,每一个tick,如果没有其他Dart Code在执行,就会做如下的事情(伪代码): voideventLoop(){while(microTaskQueue.isNotEmpty){fetchFirstMicroTaskFromQueue();executeThisMicroTask();return;}if(eventQueue.isNotEmpty){fetchFirstEventFromQueue();executeThisEventRela...
Event Loop and Multithreading Dart是一个单线程模型。但是你的Flutter应用同样可以同时做多件事情,这就是「Event Loop」发挥作用的地方。Event Loop是一个无尽的循环,它执行预定的events。这些events(或者只是代码块)必须是轻量级的,否则,你的应用程序会感觉卡顿。 每个event,如按下按钮或网络请求,都被安排在一个事...

而Dart上可以凭借这么几行代码就实现一个Event Bus,同样的道理,背后有着一个分非常有气场的男人在支持,这个男人就是Stream。首先来看一看Event bus的创建。 Event bus的创建 代码语言:javascript 复制 EventBus({bool sync:false}){_streamController=newStreamController.broadcast(sync:sync);} ...
