相关疑难解决方法(0)

我正在编写某种机器人(命令行应用程序),当我使用"forEach"方法时,我遇到异步执行问题.这是我正在尝试做的简化代码:

main() async {
  print("main start");
  await asyncOne();
  print("main end");
}

asyncOne() async {
  print("asyncOne start");
  [1, 2, 3].forEach(await (num) async {
    await asyncTwo(num);
  });
  print("asyncOne end");
}

asyncTwo(num) async
{
  print("asyncTwo #${num}");
}

这是输出:

main start
asyncOne start
asyncOne end
main end
asyncTwo #1
asyncTwo #2
asyncTwo #3

我想要得到的是:

main start
asyncOne start
asyncTwo #1
asyncTwo #2
asyncTwo #3
asyncOne end
main end

如果有人知道我做错了什么,我会很感激.
