Barcode detector

[wilav-dev]

Hello, are you planning to add an image barcode parser?

[Ahmed Mahmoud]

Hey @yamila-fraiman! There's currently a PR (#3) by @s0rta to add barcode scanning, the PR needs some changes to be ready for merging. Hopefully it will be merged soon and we will have support for it.

Could you estimate when? I need to implement it by the middle of June

[Ahmed Mahmoud]

Sorry, closed it by accident 😅.
I will try to make it happen by the end of May or so.

Now that the PR has been merged we have basic support for barcode scanning 🎉.
Check out the README for instructions on how to use it.

I upgraded the versions inside the lib build.gradle and now is working. Could you upgrade in your repo?

implementation 'com.google.mlkit:face-detection:16.1.5'
implementation 'com.google.mlkit:text-recognition:16.0.0-beta4'

[Ahmed Mahmoud]

I did upgrade all the native dependencies to latest in the latest versions of all the packages right now, can you try it out again?

[wilav-dev]

Perfect!!! Thank you
