rawValue property
The raw string value of the barcode.
On Android, this is the UTF-8 decoded string value.
On Apple (iOS and macOS), this is Apple's payloadStringValue as-is,
which is decoded using Latin-1 (ISO 8859-1) for non-QR barcodes.
Structured values are not parsed, for example: 'MEBKM:TITLE:Google;URL://www.google.com;;'.
For non-UTF-8 barcodes, prefer using rawDecodedBytes instead.
This is null if the raw value is not available.
Implementation
final String? rawValue;
