Expo Barcode Scanner native crash

Summary

Random Android users in production report crashing and 90% of our crashes come from the error below in the standalone production build.

Important to note it crashes without the user even navigating to the screen.

This is the entirety of the code I use, and I am only scanning QR codes:

import { BarCodeScanner } from 'expo-barcode-scanner';

...

 const [hasPermission, setHasPermission] = useState(false);

  useEffect(() => {
    const requestPermissions = async () => {
      const { status } = await BarCodeScanner.requestPermissionsAsync();
      setHasPermission(status === 'granted');
    };
    requestPermissions();
  }, []);

if (!hasPermission) return null;

return ( 
   <BarCodeScanner
        onBarCodeScanned={() =>   Analytics.logEvent('KioskScan')}
        style={{ width: '100%', height: '100%', position: 'absolute' }}
  />
);

Managed or bare workflow? If you have ios/ or android/ directories in your project, the answer is bare!

managed

Reproducible demo or steps to reproduce from a blank project

Can’t reliably reproduce, but it’s a native crash in the managed workflow so I’m fairly certain it is an SDK issue otherwise Sentry would have thrown something.

Same problem here. Using expo managed workflow. Just scanning QR-Code, on iOS everything works fine, on android the app crashes (100%) before the camera screen is shown. I can´t see any error-message in debugger. Used the example code in documentation of “BarcodeScanner”. Tried the same with just expo-camera (for what we need expo-barcode-scanner while expo-camera provide the same functionality?) but with same result. => crash on android before opening camera.

@Joshandrews43, please open a new issue for that. Thanks 😉
