I'm trying to create an android app using B4A which holds a Barcode or QR code, so my question is: does anyone know the code for generating Barcode or Qr scanner in B4A. thanks
You can try this http://www.b4x.com/android/forum/threads/abzxing-barcode-reader.7303/ It uses an external app (Zxing) to scan the barcode, which then returns the value of the barcode

I built an simple App which scans your QR Code from an external Scanner and displays it on the screen. The QR code contain the Firebase user id which contains lower and uppercase letters. enter image description hereI tried it on an emulator in windows while connecting the External scanner with usb and it worked fine. After running the app on a real device I realized that the QR Code which got scanned only returns the data in all lowercase letters. I don’t understand why. I then exited the flutter app and tried to see if it’s a scanner issue. Turns out anything other than flutter reads the QR code as it is. So it’s not a Scanner Problem. But it’s neither a flutter Problem because it worked on the Emulator so I can’t figure out what the problem is.
I am currently developing an application which has a profile page for patients to input their details etc. using flutter
I am wondering if anyone can help me or give me some direction on how to generate a qr code that specifically links to their profile once a user signs up. I have qr scanner built into the app and would like to be able to scan the qr code on someone elses phone and bring up their profile.
I can't seem to find anything around what I want or it's just because typing qr code into google comes up with guides on how to create a scanner only.
you can use the QR Flutter package here to generate the qr code. https://pub.dev/packages/qr_flutter
you will need to come up with String that will be used to reference the profile... either a url or a profile id. then pass that to QrImage:
QrImage(
data: "your_string_here",
version: QrVersions.auto,
size: 200.0,
),
I have zxing libray using that libray I wan to generate barcode of given text, How I can achieve this?

In my project I have to get the barcode type from its barcode number. Is there any framework or piece of sample code out there that can handle this on both iPhone and Android?
I have Googled around and found nothing.
Look at http://code.google.com/p/zxing/. This includes a barcode generator.
ZBAR sdk is normally used to read QRcode or barcode & convert it to user data. Can we use ZBAR API to create QRcode for iphone?
As far I know Zbar SDK can only be used to read.
Maybe this link will be of some help.

https://github.com/myang-git/QR-Code-Encoder-for-Objective-C worked well to generate QR Codes even with much content and UTF-8 characters (where some other generators I tried failed). The project is active and Apache 2.0 licensed.
