string static method

String string(
  1. String data, {
  2. int? max,
  3. int? seed,
})

Generates a random string of specified length from the given character set.

Parameters:

  • data: The character set to use for generating the string.
  • max: The length of the generated string.
  • seed: Seed for the random number generator. Default is null.

Example:

String randomString = RandomProvider.string('abc123', max: 8, seed: 42);
// Result: Random string of length 8 using characters 'a', 'b', 'c', '1', '2', '3'.

Implementation

static String string(String data, {int? max, int? seed}) {
  max ??= data.length;
  final Random random = Random(seed);
  var characters = data.characters;
  var value = '';
  for (int i = 0; i < max; ++i) {
    final a = characters.elementAt(random.nextInt(characters.length));
    value = "$value$a";
  }
  return value;
}
