如何在Dart中获取时间戳？ [英] How to get a timestamp in Dart?

问题描述

我一直在学习Dart，但是我不知道如何生成时间戳。我已经尝试过：

I've been learning Dart, but I don't know how to generate a timestamp. I have tried this:

void main() {
  print((new Date()).millisecondsSinceEpoch);
}

多亏了IDE，我才能够做到这一点，但是
我收到一个令人困惑的错误：

Thanks to the IDE I was able to get this far, but I'm getting a confusing error:

Exception: No such method: 'Date'

帮助？

推荐答案

您几乎做对了。您只是没有使用命名构造函数：

You almost had it right. You just did not use a named constructor:

void main() {
  print(DateTime.now().millisecondsSinceEpoch);
}
