Dart

import 'package:chilkat/chilkat.dart';

void main() {
  final dt = CkDateTime();

  // A ULID must be exactly 26 chars in length,
  // and is composed of the following chars: 0123456789ABCDEFGHJKMNPQRSTVWXYZ
  // Note: The ULID alphabet excludes the letters I, L, O, and U

  // Here's a valid ULID
  var ulid = '01GRGCH4J88RECEN4D4VK4F629';
  var valid = true;
  try {
    dt.ulidValidate(ulid);
  } on ChilkatException {
    valid = false;
  }
  print('valid: $valid');

  // Here's an invalid ULID
  ulid = '71GRGxx4Jr8RECEN4D4VK4F62!';
  valid = true;
  try {
    dt.ulidValidate(ulid);
  } on ChilkatException {
    valid = false;
  }
  print('valid: $valid');
