Yes I've run into this, too.

Will this somehow be updated? I think it's a nice idea.
Hopefully this Lib is not created and immediately abandoned.

Hi,
Can you provide a full example for me to reproduce the jpg issue?

Hopefully this Lib is not created and immediately abandoned.

Yeah it's be a bit sad. I created this lib mainly as an experiment to see what could be the performance of a dart-only QR decoder bind to the standard flutter camera stream.

I plan to have another look when Dart Isolate become faster (dart-lang/sdk#46754).

Hi, sorry - it's now working with "decodeImage" instead of "decodeJpg". The PNG version worked then I tried JPG and had an error and so this issue so I thought it's the same. Now I have no errors and it works.

I use this on the server since we have users that have incredibly slow smartphones that struggle with detection.
Somehow this lib is able to decode QR from jpg with a quality of 0.05 (canvas.toDataUrl('image/jpeg', 0.05)) which is nice since for a scan I just send this low resolution image to the server which is 5kb.

This is really fine for our usecase and other libs don't have such a great detection.

Example (rectangle is to hide qr data):

This is detected just fine. We would also have use cases for bar codes. Thanks! :-)
Please keep it running I think it's really good to port such code bases.
