Parse MRZ

final mrz = [
  'P<UTOERIKSSON<<ANNA<MARIA<<<<<<<<<<<<<<<<<<<',
  'L898902C36UTO7408122F1204159ZE184226B<<<<<10'
];

final result = MRZParser.tryParse(mrz);

// Alternatively use parse and catch MRZException descendants
try {
  final result = MRZParser.parse(mrz);
} on MRZException catch(e) {
  print(e);
}

Parse Driver License

final driverLicense = [
  'D1NLD11234567890ABCDEFGHIJKLM7'
];

final result = DriverLicenseParser.tryParse(driverLicense);

// Alternatively use parse and catch MRZException descendants
try {
  final result = DriverLicenseParser.parse(driverLicense);
  print(result.documentNumber); // 1234567890
  print(result.countryCode); // NLD
} on MRZException catch(e) {
  print(e);
}
