Implementation

DateTime? toDateTime() {
  if (length != 10) return null;

  final List<String> splittedNums = split('/');
  if (splittedNums.length != 3) return null;

  final int day = int.parse(splittedNums[0]);
  final int month = int.parse(splittedNums[1]);
  final int year = int.parse(splittedNums[2]);

  return DateTime(year, month, day);
