1. (iOS + Android) Activate without screenguard, if you just want to detect and receive event callback only.

ScreenGuardModule.registerWithoutScreenguard(
	(_) => {
	.....do anything you want after the screenshot 
});

1. Deactivate all the screenguard

ScreenGuardModule.unregister();

Limitation

This library support blocking screenshot for iOS 13+ only.

register supports background color for the layout received after screenshot and event callback for iOS only.

On Android, if you want to use callback, consider using registerWithoutScreenguard instead, as you might not receive any event after a screenshot has been triggered if using with register.
