Expo Camera barcode scanner not working on WEB (Chrome)

I have the same problem: Could this be a camel-case mismatch between the props onBarCodeScanned and onBarcodeScanned which are both used?

same here! It works well on the mobile app but on the web it is not working and not scanning any QR code.

@t0ma5h did you find any solution?

Not as of yet on SDK51. But just using sdk 50 for the time being should work

Yes, it seems like the current version of camera (SDK51) is using types from the camera/legacy.

Some props have been renamed (such as onBarCodeScanned -> onBarcodeScanned and type -> facing) and simply no longer plays well with the current API.

This PR (originally there to fix the camera-facing-issue) has also targetted the onBarCodeScanned issue as a side-effect.

#30277

The current implementation only seem to work with QR-codes though. It should work if you feed the CameraView with barcodeScannerSettings (instead of barCodeScannerSettings) and onBarcodeScanned (and target QR-codes), but TypeScript will yell at you until this PR or any other fix is applied.

I believe this will get some attention pretty soon as the camera/legacy will be removed in SDK52 (if I remember correctly). In the meantime though, it would be good to get this patched up.
