Inconsistent type in barcode scan result when using expo-camera/next #26953

Minimal reproducible example

https://github.com/steveliles/expo-barcode-scanning-bug/blob/main/App.js

Summary

Steps to reproduce:

  • run the app in the repro repository with expo run ios --device and pick a real device with a camera
  • scan an ean13 barcode
  • notice that the type is reported as "org.gs1.EAN-13"
  • now run the app in with expo run android --device and pick a real device with a camera
  • scan an ean13 barcode
  • notice that the type is reported as 32 (the number, not a string)

I have two issues:

  1. When we configure the scanner we use "ean13", but the type is reported on iOS as "org.gs1.EAN-13". Its ok I guess, but a bit surprising that the type in the result does not match the type in the config, and there should probably be a list somewhere of what these result types will be (or perhaps constants to match against)?
  2. Android is returning numbers instead of strings, inconsistent with iOS and quite opaque.
