flutter pub add eventify基于插件公开信息、社区数据与项目使用情况整理的选型参考。
Eventify 是一个可取消的事件发射器，专为 Dart 中的上下文感知、事件驱动编程而设计。它通过内置的取消支持，允许事件的发出和监听，实现组件间的高效通信，确保不会出现内存泄漏。非常适合用于管理应用不同部分的状态变化、用户交互或异步工作流。该包支持所有主要平台，包括 Android、iOS、Web、macOS、Windows 和 Linux，使其在跨平台开发中具有高度的通用性。

EventEmitter for dart. This can be used in any application to register for events and get notified once it is fired.
This library provide mechanism to register for event notifications with emitter or publisher and get notified in the event of an event.
One main advantage of the mehanism is that, it support context from where the subscriber is listening. The context could be any additional data the subscriber is interested in.
Another feature this has is the ability to receive sender information, which could be handy if the subscriber wish to know about the publisher.
void performAddition(){
}
EventCallback cb = (ev, cont) {
if (null != ev) {
switch (ev.eventName) {
case "add":
performAddition();
break;
}
}
};
EventEmitter emitter = new EventEmitter();
Listener listener = emitter.on("add", this , cb);
emitter.emit("add","keyboard",10);
As shown in the above example, it is easy to register for events and get notified once it is triggered.
