Current behavior

I'm struggling to scan these barcode labels, and it only works very rarely. I'm using an iPad Air. I have another app that can scan them without any issues.

Expected behavior

To scan the codebar correctly

Reproduction

https://github.com/FVolral/.capacitor-app

Steps to reproduce

$ npm run build && npx cap sync && npx cap open ios

The reproduction should try to scan the barcode use readBarcodesFromImage() but it doesn't work, not sure if it's me or a bug from the plugin. a working repro that use it may help.

Other information

My reproduction is not working, and I haven't been able to find a valid reproduction scenario. So, I did what I could, but it leads to a 'File does not exist' error when I'm trying to use the 'readBarcodesFromImage()' method. As far as I can tell, the path should be correct since the images load correctly in the DOM, right?".

Also, on my iPad, I can scan these insemination glitter barcodes almost instantly using an app called 'QR Reader' developed by Tap Media.

Those barcode use CODE_128 formats.

Hi @FVolral,
thank you for your request.

No, you need to provide a native path, not the web path. Here you can find an example: https://github.com/robingenz/capacitor-mlkit-plugin-demo/blob/main/src/app/modules/barcode-scanning/barcode-scanning.page.ts#L86:L98

I tried it myself and i can reproduce your issues. But I am not sure if the plugin can do much here. After all, the mlkit sdk is responsible for detecting the barcodes.
It's best to create an issue in this repository: https://github.com/googlesamples/mlkit
But I will leave this issue open for now. Please update this issue if you have any news.

Yep, that's what I thought. I will open an issue on mlkit. Thank you for your response.
