IsolateTask class
IsolateTask：Dart多线程（Isolate）管理工具类
说明
便捷地在Flutter/Dart项目中管理多个Isolate，实现耗时任务分发与生命周期管理。
示例用法
// 1. 定义isolate入口函数
void isolateFunction(List<dynamic> args) {
SendPort sendPort = args[0];
dynamic taskData = args[1];
// 执行耗时或计算密集型任务
var result = performComputation(taskData);
// 将结果发送回主isolate
sendPort.send(result);
}
// 2. 主isolate中使用IsolateTask管理
void main() async {
// 启动新isolate
await IsolateTask.spawn('worker1', isolateFunction, '任务参数');
// 检查isolate是否存在
if (IsolateTask.exists('worker1')) {
print('worker1 已启动');
}
// 结束指定isolate
IsolateTask.kill('worker1');
// 结束所有isolate
IsolateTask.killAll();
}
