Hello Philip. Thanks for the amazing work you are doing on this space. This video could not have come at a better time. However, I am kinda stuck on how to run and stop the scanner on button events and also run the scanner for a given period of time before throwing a not found error.

Once again, thanks a great deal

I wanted to navigate to another screen through navigation controller. it goes to that screen but the functionality doesn't work as expected on that screen. and the design is also not properly shown. Can you make a tutorial about navigating to another screen after successfully scanning the qr code?

Heyy Philip, I'm coming back here cz I thought I break my code but for some reason this solution is not working on Pixel 6A, I installed the same repo from github, It's working on emulator, on my OnePlus but not on Pixel, I tried updating zxing library version and other solution but nothing is working. Can you please help.

[vildanvinanda]

thank you very much for the video philip, can you make us a video how to enter data in the qr code and the qr code is stored in firebase and when scanned it will display the stored data

Great video here, .
I actualy Search how to build qr code scanner a long ago, . And endup with mlkit + camera x, . With kotlin xml, .

Now the problem is here, .
Which is better using zink lib or MLKit?
And can you make video how to build qr code scanner using MLkit with compose?

Anway, . Big thanks for your video this time, 😁

It has been very didactic, congrats Philipp.

Getting this error: Cannot access class Check your module classpath for missing or conflicting dependencies. Not able to find a solution.

Gotta limit the camera resolution by adding this to the AndroidView in the MainActivity:

.setTargetResolution(
Size(
640, // previewView.width,
480, // previewView.height
)
)

This is great, but could you share a tip or where to look for rotation PlanarYUVLuminanceSource or BinaryBitmap? So it can work on portrait as well
