Digit.max constructor

Digit.max(
  1. int max, {
  2. String? mal,
  3. String? long,
})

Constrains the input data to the digits 0-9 and its length (number of digits) to a maximum of max digits.

max the maximum number of digits; it must be > 0. mal "malformed", the error message if non-digit characters are found; the default value is 'non-digit character(s) found'. long the error message if the input length is longer than max digits.

Implementation

Digit.max(int max, {String? mal, String? long})
    : assert(max > 0),
      _valDig = _DigitImpl(mal, Len.max(max, long: long).call).call;
