Laravel custom validator function not being called

Question

I'm trying to add a custom rule for validator, but it's not working at all, the function is not even called. I took this from documentation(https://laravel.com/docs/5.4/validation#custom-validation-rules):

In AppServiceProvider::boot I have this:

Validator::extend('foo', function ($attribute, $value, $parameters, $validator) {
   return false;
});

and In my controller I have this:

$validator = Validator::make($request->all(), [
    'myField' => 'foo',
]);

The validator doesn't fail. What am I doing wrong?

Fixed it. My json was wrong and if input value is null(or empty) then custom Validator::extend rules won't be checked. So solution would be

Validator::extendImplicit('foo', function ($attribute, $value, $parameters, $validator) {
    return $value == 'foo';
});

or $request field that isn't empty
