Int class
Integer constraints — limits input data to integer values.
Examples:
- valid input: "1", "+555", "123", "-1".
- invalid input: "9.99", "-1.1", "A", "12A", "12.A3".
Constructors
- Int({String? mal})
- Constrains data to integer numbers.
- Int.max(int max, {String? mal, String? large})
-
Constrains data to integer values that are less than or equal to
max. - Int.min(int min, {String? mal, String? small})
-
Constrains data to integer numbers greater than or equal to
min. - Int.neg({String? mal, String? pos})
- Constrains data to negative integer numbers (zero excluded).
- Int.pos({String? mal, String? neg})
- Constrains data to positive integer numbers (zero included).
- Int.range(int min, int max, {String? mal, String? small, String? large})
-
Constrains data to integer values within the range
min–max.
