Unable to recognize the QR code from the image, the Codes are empty strings on Android and iOS

[b-fab-michael]

Please fix this issue as soon as possible, otherwise I'll have to add another image QR code recognition library for this.

Hello @b-fab-michael, could you kindly share the demo image required to replicate your problem? Thank you.

Hello @b-fab-michael, could you kindly share the demo image required to replicate your problem? Thank you.

` void _onPicTap() async { final res = await ImagePickerUtils.pickerPaths( galleryMode: GalleryMode.image, selectCount: 1, showGif: false, compressSize: 5120, ); File file = File(res[0].path ??

This is my code. Please tell me. Is there anything else I need to improve?

@khoren93 I am also getting always isValid = false and empty result from scanned images.

@b-fab-michael @ozkayas please check the v1.5.2. Thanks!

Doesn't work with any QR code image I've tried. I've using version 1.5.2.

For testing purposes, I created a QR with an online tool from the string "Test123" and selected it with the file_selector package.

Inside of the same widget:

@OverRide void initState() { zx.startCameraProcessing(); super.initState(); }

@OverRide void dispose() { zx.stopCameraProcessing(); super.dispose(); }

My Code: final XFile? file = await openFile(); if (file == null) return; log('Selected file: ${file.path}'); log('FileBytes: ${(await file.readAsBytes()).length}'); final result = await zx.readBarcodeImagePath(file); log('ResultDuration: ${result.duration}'); log('ResultError: ${result.error}'); log('ResultFormat: ${result.format}'); log('ResultIsInverted: ${result.isInverted}'); log('ResultIsMirrored: ${result.isMirrored}'); log('ResultIsValid: ${result.isValid}'); log('ResultPosition: ${result.position}'); log('ResultRawBytes: ${result.rawBytes}'); log('ResultText: ${result.text}');

Output: [log] Selected file: content://com.android.providers.media.documents/document/image%3A1000000179 [log] FileBytes: 26487 [log] ResultDuration: 23 [log] ResultError: [log] ResultFormat: 0 [log] ResultIsInverted: false [log] ResultIsMirrored: false [log] ResultIsValid: false [log] ResultPosition: Instance of 'Position' [log] ResultRawBytes: null [log] ResultText:

It there any solution yet as I am also facing same issue. Not able to scan qr code from gallery image

[U-WHY]

Same issue and I can't find any solution for that. There is my code & image, i test it in android api 34 & 29

Future _decodeQrCode() async { final XFile? file = await ImagePicker().pickImage(source: ImageSource.gallery); final DecodeParams params = DecodeParams( imageFormat: ImageFormat.rgb, format: Format.any, tryHarder: false, tryInverted: false, isMultiScan: false, ); final Code result = await zx.readBarcodeImagePath(file!,params); if (result.isValid) { print(result.text!); } else { print('WTFWTF!!'); } }

Any update on this?

Any update on this?

currently i am using this code and it works super good.

   final DecodeParams params = DecodeParams(
      imageFormat: zxing.ImageFormat.rgb,
      format: Format.any,
      tryHarder: tryHarder,
      tryInverted: tryInverted,
      isMultiScan: false,
    );
    final text = (await zx.readBarcodeImagePath(file, params)).text;
