dart笔记12：Future.delayed延迟任务

import 'dart:async';

import 'dart:io';

void main() {
  print('start');

  Future.delayed(Duration(seconds: 3), () {
    print('延迟任务');
  });

  Future(() {
    sleep(Duration(seconds: 5));
    print('耗时任务');
  });

  print('stop');

  //执行结果：
  // start
  // stop
  // 耗时任务
  // 延迟任务
}
