randomInRange function

int randomInRange(num min, num max, [ int? seed ])

Generates a random integer within the specified range.

Returns a random integer between min and max, inclusive.

min and max are treated as integer bounds via toInt(). Throws ArgumentError if min is greater than max.

If a seed is provided, it is used to initialize the random number generator for reproducible results. Example:

int randomNumber = randomInRange(1, 10);

Implementation

int randomInRange(num min, num max, [int? seed]) {
  if (min > max) {
    throw ArgumentError('min must be less than or equal to max.');
  }
  return ((max - min + 1).random(seed) + min).toInt();
}
