How to track screenshot event on ios in flutter app?

Question

iOS

It is necessary to block the ability to take screenshots in the application. On ios, blocking screenshots is not possible, but it is possible to catch the event of taking screenshots and replace the screen itself (according to official information).

The question is, is there a real possibility without native code to catch this event and change the contents of the screenshot?

Answer 1

as an option to catch a screenshot, you can use this library https://pub.dev/packages/screenshot_callback

import 'package:screenshot_callback/screenshot_callback.dart';

ScreenshotCallback screenshotCallback = ScreenshotCallback();

screenshotCallback.addListener(() {
  //Void funtions are implemented
  print('detect screenshot');
});
