generateRandomString function

Implementation

String generateRandomString(int length) {
  const characters =
      'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
  Random random = Random();

  return String.fromCharCodes(
    Iterable.generate(
      length,
      (_) => characters.codeUnitAt(random.nextInt(characters.length)),
    ),
  );
}
