Merchant class
A class representing detailed information extracted from a Merchant QR Code.
This class provides various details encoded within a Merchant QR Code, including the Merchant PAN (Primary Account Number), Merchant ID, Merchant Name, Merchant Location, and other merchant-specific _raw information stored in the QR code's tags. Additionally, it provides utility methods for parsing and validating this information.
Key Fields:
_raw: A map containing the _raw data extracted from the QR code. Each tag within the map corresponds to a specific merchant detail, such as the Merchant PAN, ID, Name, etc.
Example usage:
final qrData = Merchant(someQrDataMap);
String? pan = qrData.pan;
String merchantName = qrData.name;
