iOS analyzeImage from gallery not working, always returns false

Could you provide the version of mobile_scanner that you use, and a minimal reproducible sample?
Please also include the file from the gallery that you are trying to analyze.

Could you also provide a sample file that isn't working with analyzeImage() ?

With a "sample file", I meant an image that has some kind of barcode in it that was not detected. The above images definitely do not have a barcode at all, so the result is working as intended for those.

I ran example, but did not recognize my QR code

The same issue.

when I use qr_flutter, and generate a qr image.

QrImageView(
  data: '[1234567890](https://github.com/juliansteenbakker/mobile_scanner/issues/967)',
  version: QrVersions.auto,
  gapless: false, // important
  size: 200.0,
),

use RepaintBoundary to get snapshot.
analyzeImage

@navaronbracke Thanks

I'm experiencing the same issue. When I generate a QR code using pretty_qr_code.dart or other libraries on the same phone, the analyzeImage() function fails to recognize it (e.g "No barcode found!" ). However, QR code images I download from the internet work perfectly. I thought the package im using to generate the QR code generation was the problem, but I've tried multiple generators with the same result. I even set a white background to rule out issues with transparent QR images, but that didn't make a difference either. Are there any other potential solutions to this problem?

By the way im using https://github.com/juliansteenbakker/mobile_scanner/blob/c0ac2453e303c9374228076810bb52732e928a11/example/lib/scanner_button_widgets.dart#L5:L49

I am experiencing the same issue on iOS, it works perfectly on Android. The QR code has been generated using the QR Flutter package.

The analyzeImage() API does not return any QR code when the file is read from the gallery.

Is there any solution to this ?

Hello, I am having this same error, the reader stopped reading the images from the gallery, the path that I am passing as an argument is /private/var/mobile/Containers/Data/Application/2A5D7976-D4C1-4576-9CB2-63FA19794306/ tmp/image_picker_BC16B31F-1CDF-47B4-9C25-317BA992F31F-1678-000000DAD48F28FE.png
obtained with the ImagePicker package.

I am using version ^4.0.0

I had the same problem and it happens on PNG images. If you edit or crop the image (get's saved as JPG on iPhone at least) it works!

This works for me (tried edit or crop image in Photos before use analyzeImage . This will turns from PNG to jpg).
So, I thought that saving QR Code image (generated by qr_flutter) to Photos directly with .jpg extension with screenshot to capture QR image and gal to save image to Photos could work as well but it's not.

  Future<void> saveImageToGallery(Uint8List bytes, {String name = 'img.jpg'}) async {
    var canAccess = await Gal.hasAccess(toAlbum: true);

    if (!canAccess) {
      canAccess = await Gal.requestAccess(toAlbum: true);
    }

    if (!canAccess) {
      throw Failure(message: FileMessages.galleryAccessDenied);
    }

    final imagePath = await getTemporaryFile(name, bytes);
    await Gal.putImage(imagePath.path);
  }

This issue may be similar as #1271 . The author released this fix in version 7.0.0-beta.4 . I tried it and it's work for me. Hope this help.
