如何检测硬件按键? [英] How to detect hardware key taps?

问题描述

我正要检测当flutter应用程序处于前台或打开状态时是否按下了任何硬件按钮.*

I am at a point where I need to detect if any of the hardware buttons was presses when the flutter app is in foreground or when it is open.*

例如，当有人按下某个音量或另一个按钮(即使是关闭电源的按钮)时，我想在我的应用中执行一些操作.

For example, when someone presses a volume or another button (even if it is the power off one) I want to perform some action in my app.

我知道当一个flutter应用程序打开并且正在查看应用程序日志时，我点击了任何硬件按钮，则与该水龙头相关的活字印在了日志中.

I know that when a flutter app is open and I am looking at the app logs and I tap any hardware button is tapped the lops related to that tap is printed in the logs.

就像我按下音量下调"键时一样，检测到的相关日志会打印在日志中.

Like when I press Vol down Key Down Tap Detected related logs are printed in logs.

执行以上任何指定的操作时如何执行功能?

How do can I perform a function when any of the above specified action is performed?
