Describe the bug Hello, I am trying this plugin to scan the barcode, it works fine in Android when using without options. The result is like this:

I/flutter ( 7122): Barcode
I/flutter ( 7122): 028190009849
I/flutter ( 7122): unknown
I/flutter ( 7122): UPC_A

However I need to restrict the barcode type so I give the options like this:

 var options = ScanOptions(restrictFormat: [
      BarcodeFormat.unknown,
      BarcodeFormat.ean13
    ]);
    var result = await BarcodeScanner.scan(options: options);

    print(result.type); // The result type (barcode, cancelled, failed)
    print(result.rawContent); // The barcode content
    print(result.format); // The barcode format (as enum)
    print(result
        .formatNote); // If a unknown format was scanned this field contains a note

However the result now is changed into EAN-13, it should be detected as UPC_A same like with no options.

flutter: Barcode
flutter: 0028190009849
flutter: ean13
flutter:

Also in IOS the barcode is always detected as EAN13 not UPC.

To Reproduce Steps to reproduce the behavior:

1. Add the options code in barcode scan
2. Scan the barcode image
3. Check the result

Expected behavior It should be show as UPC_A Format

Logs Second Result after restricted:

EAN13 is compatible to UPC. On iOS the default AVFoundation barcode detection is used. I think we don't have a chance to fix this "problem". You can restrict the barcode formats in the scan options and exclude ean13 if you need to scan this type of codes as UPC.

If i exclude ean13 the app dont scan anything.
