DivisibleByValidator class
A validator that checks if the value is divisible by denominator.
The DivisibleByValidator can be used with FieldControllers holding
values of type int. It ensures that the
value is divisible by denominator.
If the value is null it is treated as valid by default.
Properties
- denominator: The denominator of the division.
- message: An optional custom error message to display when invalid.
Example
FieldController<int> field = FieldController(
key: 'number',
validators:[DivisibleByValidator(4)],
);
// If field.value = 3, validation fails.
// If field.value = 4, validation passes.
// If field.value = 8, validation passes.
