invalid method

  1. @override
bool invalid(
  1. DateTime date
)
override

Returns true if the date is invalid for this DateValidator.

This is the opposite of valid. Implementations that return true for invalid should also return false for valid.

Usually, this will be implemented as !valid(date) by DateValidatorMixin. However, if there is a simpler way to check for invalid dates, it can be implemented here.

Implementation

@override
bool invalid(DateTime date) => !valid(date);
