"required" not working with "dateFormat"

[2ik]

accidentally discovered such a problem

php8.1

example:

$validator = new Validator([]);
$validator->mapFieldsRules([
    'dateFrom' => ['required', ['dateFormat', 'Y-m-d']],
]);
$validator->validate();

output error:

ERROR: date_parse_from_format(): Passing null to parameter #2 ($datetime) of type string is deprecated on line 764 in file path/vlucas/valitron/src/Valitron/Validator.php.

I also wanted to know, how about not checking other rules if the required field is missing?
