…tate. (#40542) ## Description This adds app lifecycle notification for macOS and Linux, and adds a new `hidden` state to the `AppLifecycleState` enum.

For my own understanding (since this returns a Future): Am I allowed to delay responding to this for however long I want? Or do platforms impose a timeout here?

As far as I can tell, you can delay as long as you want and they will wait for you to respond. I suppose they might put up a system dialog saying that you took too long and ask if your app should be forcefully killed, but that won't affect the way the API works from the developer's point of view.

The more I think about it, the stranger I find it that this optionally takes in a binding. I don't think we use this pattern elsewhere and would expect tests to just install their own (global) custom binding if they need some custom behavior. I also can't think of a testing scenario where you'd really need a custom binding here... I think all the tests you're adding in this PR would pass if you wouldn't pass in the binding manually....

Okay, This was a suggestion that @Hixie had early on. It does seem convenient, and in normal usage it doesn't make any difference. It would be less complex to not have it, though.

Description
This adds
AppLifecycleListener, a class for listening to changes in the application lifecycle, and responding to requests to exit the application.It depends on changes in the Engine that add new lifecycle states: flutter/engine#42418
Here's a diagram for the lifecycle states. I'll add a similar diagram to the documentation for these classes.
