I'm developing a webapp with react native and expo in which I need to be able to scan EAN13 barcodes. I've been using expo's documentation to do this, but I've hit a wall.

As much as I try to get the barcode from a photo, everytime I try to use scanFromURLAsync it throws the following error:

_ExpoCameraManager.default.scanFromURLAsync is not a function At first I thought it might be a deprecated method but in expo's documentation it says that it is in ver52 (which is the one I'm using)

Does anyone know why is this happening and how I might solve it, I leave my code below as well as some clarifications.

• I have already tried importing just scanFromURLAsync directly instead of Camera, it gave the same problem.
• Please ignore all the mistakes I've surely made that have nothing to do with the question, this code is a draft just to see if I can make it work.
• Thank you in advance :)
