Why doesn't required_unless work with boolean?

Question

Laravel

There is a piece of code:

$validator = Validator::make($args, array(
            'name' => 'required|min:4',
            'phone' => 'required|numeric|digits_between:3,15',
            'delivery' => 'required|boolean',
            'address' => 'required_unless:delivery,false|min:10|max:60',
        ));

If you send parameters
delivery: false
address: "test"
then the error The address must be at least 10 characters , i.e. the validator skips
required_unless:delivery

, I understand that in required_unless:delivery,false false acts as a string, and in the parameter I send a boolean type.

How can this be bypassed?

Answer 1

delivery: 0
'required_unless:delivery,0'

Answer 2

'address' => [
   // $this если в реквест файле или $request
   Rule::requiredIf($this->delivery),
  'min:10'
]
