IpValidator class

A validator that checks if the value is a valid ip.

The IpValidator can be used with FieldControllers holding values of type String. It ensures that the value is a valid ip.

If the value is null it is treated as valid by default.

Properties

• ipType: The type of ip to validate. Can be IpType.ipV4, IpType.ipV6 or IpType.ipV6Short
• message: An optional custom error message to display when invalid.

Example

FieldController<String> field = FieldController(
  key: 'string',
  validators:[IpValidator(IpType.ipV4)],
);

// If field.value = '1234.456.78', validation fails.
// If field.value = '123.456.7.8, validation passes.
