format method
Driving license format is HR-0619850034761 or HR06 19850034761.
by default it will return with hyphen.
Implementation
String? format(String? dlNumber, {bool withHyphen = true}) {
if (dlNumber == null) return null;
// remove the space and hyphen (-) from [dlNumber]
// because the driving license number can have these
dlNumber = dlNumber.replaceAll(RegExp(r"-|\s+"), "");
if (withHyphen) {
if (dlNumber.length > 2) {
return (dlNumber.substring(0, 2) + '-' + dlNumber.substring(2))
.toUpperCase();
}
return dlNumber.toUpperCase();
} else {
if (dlNumber.length > 4) {
return (dlNumber.substring(0, 4) + ' ' + dlNumber.substring(4))
.toUpperCase();
} else {
return dlNumber.toUpperCase();
}
}
