Hint option of scanBarcode method is not applied

[ToKruAmApp]

Calling the scanBarcode method with a hint to specify the type of barcode to be scanned doesn't seem to work. Calling scanBarcode({ hint: 1 }) for example should only allow AZTEC codes but somehow QR codes still get detected.

I think this is true for the majority of the configurable options. The scanBarcode() method implementation uses options to setup an object param = {...} which is a similar object but with some default values applied. Here's a snippet:

const param = {
    facingMode: options.cameraDirection === 1 ? 'environment' : 'user',
    hasScannerButton: false,
    scanButton: options.scanButton === undefined ? false : options.scanButton,
    ...
}

It looks like the only places param's fields are used are:

1. To set the fps of Html5QrcodeConfig when calling window.OSBarcodeWebScanner.start(...)
2. To set the facing mode when calling window.OSBarcodeWebScanner.start(...)

No other options have an effect on the execution of the method.

EDIT:
Obviously as a capacitor plugin the implementations vary by platform. I didn't think to check but each platform actually uses different subsets of the options, which isn't included in the docs. The swift implementation uses the instructions , button text, camera direction and device orientation as seen below:

let scannedBarcode = try await manager.scanBarcode(with: scanArguments.scanInstructions, 
                                                   scanArguments.scanButtonText, 
                                                   scanArguments.cameraDirection, 
                                                   and: scanArguments.scanOrientation)

and the android:

val parameters = OSBARCScanParameters(
                   scanInstructions = scanInstructions,
                   cameraDirection = cameraDirection,
                   scanOrientation = scanOrientation,
                   scanButton = scanButton!!,
                   scanText = scanText!!,
                   hint = hint,
                   androidScanningLibrary = androidScanningLibrary
)

This gives me the impression that it would be very difficult to have a shared experience cross platform if using this plugin, as the iOS and Web implementations are pretty barebones in comparison.

Indeed, we provide hint: CapacitorBarcodeScannerTypeHint.QR_CODE and nevertheless, it's able to scan 1D barcodes.
