barcoder | Lightweight Barcode Encoding Library for .NET Framework | Barcode Processing library

Bit of background:

I'm adding a feature to one of our clunky old systems to keep it ticking over until such time as the new version of the system is at a level where this feature could be brought to a level where it can support this feature.

The system is a combination of C# and VB (yes, I know, I'm slowly phasing the VB out). Essentially, I'm adding this simple API Controller (there will be one or two more methods once finished, this is just me getting the first bit working):

Suppose I have ScanActivity using jetpack compose that can scan Barcode, the result will shown in TextField and result will survive from configuration change(e.g screen rotation). I won't use StateFlow because after the result shown then I rotate my screen it will call API again, but the result become empty I want to keep the result.

ScanActivity:

I make an api call which returns an array. I need to loop over this array and perform a new request per item. The following code works fine:

I'm creating a "barcoder" text field on flutter. After the page opened which is the barcoder belong,

I need to autofocus on TextField. But on the first opening, I want to hide the keyboard. And then if the user focuses on TextField The keyboard can appear.

How can I achieve this? I already try

So im getting a task by its id, im scanning a barcode i get the id and i get the data of the task, but for some reason i cant setLocation to resultData. Location, when i log resultData i get all the data of the task, when i log resultData.location i get the location object, but when i want to setLocation(resultData.location) i just get an empty object logged - note in use state default state is {}, if i just set the default state to nothing it returns undefined in the console.

I know this isn't exactly a programming question, but it is related:

I'd like to know if USB barcode scanners can scan a barcode and type the results as if it was a keyboard. The reason for this is that I would like to make a C++ console application that will take the input of the scanner using cin or getline, but that would only work if the barcode scanner types the results into my program like a keyboard, and I would like the scanner to press enter for me so I can just scan and scan without pressing it myself in between.

If it doesn't work like that, then how can I get the barcode scanner to give the variable with the results to my program? Is there a special cheap barcode scanner with a C++ api?

I would test this myself, but I am a teen with no money and I don't want to bother my parents for a scanner just to waste their money if it doesn't work.

EDIT: If there is some 3rd party api thing, I don't want to have to type so much confusing code, I would just like to type something like: barcodeResults = scanBarcodeAPI();

I am trying to test an axios request, and I need to use an auth token in order to access the endpoint, however my test fails because I am getting "Bearer null" and inputting this into my headers.Authorization. Here is my actual code below

File I'm testing:

I am using react-native-camera to scan barcodes. On iOS, where I started developing, everything works well as expected. On Android though, it will just not fire onBarcodeRead when a barcode is focused with the camera.

The relevant piece of code is the following:

I am developing a barcode reader with Xamarin.Forms. And I'm trying to scan the image on Android device.

First I select the image from the gallery with Xamarin.Essentials MediaPicker and from the path of this image I get an RGBLuminance with the Dependency class.

Then I am trying to decode this RGBLuminance with the Decode() method of the ZXing BarcodeReaderGeneric class. However, the result always returns null.

It is my demo project : https://onedrive.live.com/?authkey=%21AFLjjM91wgZkBGU&cid=58BE2C2C3447FFA2&id=58BE2C2C3447FFA2%219829&parId=root&action=locate

Command in the ViewModel class:
