Int.neg constructor

Int.neg({
  1. String? mal,
  2. String? pos,
})

Constrains data to negative integer numbers (zero excluded).

mal "malformed", the error message for non-integer input values; the default value is 'non-integer input value'. pos the error message if an input value is positive; the default value is 'it cannot be positive'.

Implementation

Int.neg({String? mal, String? pos})
    : this.max(-1, mal: mal, large: pos ?? 'it cannot be positive');
