HI getting this error in ios with latest version 1.1.9

  `(null)` is not a supported event type for RNScreenshotPrevent. Supported events are: `userDidTakeScreenshot`

      if (!__DEV__) {
        RNScreenshotPrevent.enabled(true);
        RNScreenshotPrevent.enableSecureView();
      }

      if (Platform.OS === 'ios') {
        const userDidScreenshot = () => {
          console.log('Screen shot taken');
        };
        const subscription = RNScreenshotPrevent.addListener(userDidScreenshot);
        return () => {
          subscription.remove();
        };
      }
    } catch (error) {
      console.log('error', error);
    }
  }, []);

Hey @ajayhcode,

I got this working by using the import stated:

import RNScreenshotPrevent, { addListener } from 'react-native-screenshot-prevent';

Then removing RNScreenshotPrevent from addListener. Here is my working code block:

  RNScreenshotPrevent.enableSecureView();
  RNScreenshotPrevent.enabled(true);

  useEffect(() => {
    
    const subscription = addListener(() => {
      Alert.alert('Warning', 'You have taken a screenshot of the app. This is prohibited due to security reasons.');    
    })
  
    return () => {
      subscription.remove();
    }
  }, [])

@RickRedSix Thanks for replying. I also got it resolved.
Can anybody explain this behavior
When we are using addListener like
addListener it works
but when we use it RNScreenshotPrevent. addListener
it is giving error

[nobi1007]

@ajayhcode the problem is addListener is not a data member of the exported RNScreenshotPrevent object. Please reference the source here.

is this package still working? I just tested it a few on iOS simulator but nothing happened. I tested some forks but nothing new. I need to hide content when user try to screenshot or record screen on specific screens.
