QRCodeReader | QRCode reader | QRCode Processing library

I'm trying to open the camera and allow the user to capture an image frame from within a Xamarin.Android's webview.

I've pointed the webview to this URL which hosts a few examples: https://googlechrome.github.io/samples/image-capture/index.html. The samples work perfectly when opening the URL in the device's Chrome browser but fails when opened within the app's webview. Here is my WebChromeClient implementation:

So i have a barcodescan button, I want to press it and scan an item, then retrieve the barcode and use the retrieved barcode in another button (this will send an api request with the barcode), how would i go about this?

Would love if someone could point me in the right direction, cant seem to find any answers online (probably searching for the wrong thing).

Thanks in advance!

This is partially my code:

This is what i am trying to accomplish:

1. Use a barcode scanner to scan an item and send a "GET REQUEST" to retrieve json data.
2. Modify the data with user input (change number, text etc).
3. Use the modified data/variable to send out a "PUT REQUEST" as httpbody.

I dont know what the best way to accomplish this is, im so lost! Can i somehow return the variable "parameters" out of the function so that i can modify it and send it out with another function?

The below code is not the full code, i removed a big part to make it easier to read. It contains a "get" function, dont know where to go from here.

Thanks for checking it out, just looking for someone to point me in the right direction.

I cannot understand why I'm getting StackoverflowError. I'm trying to build bitmap from an image to scan QR code. source from decode() method is build in standard way:

I am building an AAR in which i have Zxing library implemented. When i try to use this AAR in another application it gives java.lang.NoClassDefFoundError: Failed resolution of: Lcom/google/zxing/RGBLuminanceSource; in following method

When I tried to Convert Swift 3.0 to Swift 4.2 from Xcode 10.1,I got error at QRCodeReader

What I need to do to fix this issue? After update to pod 'QRCodeReader.swift', '~> 9.0.0' Error is like below

My qr code scanner stopped working on Android and I do not understand why... It worked previously and the scanner still works on iOS.

Firebase ML kit simply returns an empty list when scanning and I have tried many different android devices and QR codes but none work (anymore).

I have tried to clean and reinstall all dependencies, I tried to clear all data in Google Play services and reinstalled the app (so that it reinstalls the ML model)

I had an idea that it could possibly be the image format that is not correct, the format from the camera is in YUV_420_888 and I think it is converted into NV21 with the code below, but not 100% sure how that works.

What's annoying is that this did work before but suddenly stoped working.

This is my implementation of the QR scanner it recieves an image from the camera stream

I am using - dependencies: qrcode_reader: ^0.4.4 that's the latest version available. And it works perfectly fine when I flutter run on my phone. But when I Gradle Sync the project on Android Studio it's giving me an error. I couldn't find any solution for that problem. Here is the Error -

I'm new in iOS Programming and right now I want to build multiple environment for my current apps. But when I'm installing pods, it success, but my pods are not recognized. It shows error
