How it works...

When you create a Unity UI Toggle GameObject, it comes with several child GameObjects automatically Background, Checkmark, and the text's Label. Unless we need to style the look of a Toggle in a special way, all we must do is simply edit the text's Label so that the user knows what option or feature this Toggle is going to turn on/off.

The Awake() method of the ToggleChangeManager C# class caches a reference to the Toggle component in the GameObject where the script instance is located. When the game is running, each time the user clicks on the Toggle component to change its value, an On Value Changed event is fired. Then, we register the PrintNewToggleValue() method, which is to be executed when such an event occurs. This method retrieves, and then prints out to the Console window, the new Boolean true/false value of Toggle
