event call back before an app was terminated by user

[dragonBTV]

Do we have an event call back before an app was terminated by user?

for status saving and cleanup jobs

Sure.

import { me } from "appbit";

// register for the unload event
me.onunload = () => {
    console.log("We're about to exit");
}

Thank you!

What is necessary to stop the App ending in me.unload(), if you want to add an "Are you sure?", or is it too late?
