dart控制台应用程序中的Ctrl + c [英] Ctrl+c in dart console application

问题描述

有没有办法在dart控制台应用程序中捕获 CTRL + C

Is there a way to catch CTRL+C in dart console application?

例如，按 CTRL + C 从服务器向Web套接字客户端发送干净的关闭

For example, press CTRL+C to send clean "closing" packet to web socket clients from server instead of just brutally closing the sockets.

推荐答案

我有一个挖掘，我认为

您可以捕获stdin，例如：

You can capture stdin, for example:

import 'dart:io';

void main() {
  stdin.onData = () => print(stdin.read());
}

但不会响应 CTRL + <

but this does not respond to CTRL+C.

其他地方， process.dart > dart：io library）定义了各种信号，如SIGQUIT和 onExit（）回调，但是这用于控制子进程比主机进程。

Elsewhere, process.dart (part of the dart:io library) defines various signals, such as SIGQUIT, and an onExit() callback, but this is used to control child processes rather than the host process.
