It's crashing on iPad and iPhone after you try to scan QR code.

https://pub.dev/packages/ai_barcode this package is using this library internally and I believe it's somehow related with this package.

@mikebuss Can you please check?

Hi @imvasim777. This library is not actively maintained. If you are experiencing issues with it, I would recommend using Apple’s AVFoundation framework directly, which MTBBarcodeScanner is built on top of.
