Bug Description

When printing class, there is this line:

($property->getValue() === null && !$property->isInitialized() ? '' : ' = ' . $this->dump($property->getValue(), strlen($def) + 3)) // 3 = ' = '

which basically means that if I set value of Property to null intentionally, this value is not printed.

Steps To Reproduce

E.g. $property->setPrivate()->setValue(null) generates private $property;
But $property->setPrivate()->setValue('test') generates private $property = 'test'; properly

Expected Behavior

It should generate private $property = null;

Possible Solution

Mark null state with some constant instead of null. So it would look something like this:

class Property
{
    public const NO_DEFAULT_VALUE = '$73aad02e-7f5a-4ef2-8cdd-0fd09e6d9863§'; // hopefully no one is going to pass this string as default value

    // ...
}

// in printer:
($property->getValue() === Property::NO_DEFAULT_VALUE && !$property->isInitialized() ? '' : ' = ' . $this->dump($property->getValue(), strlen($def) + 3)) // 3 = ' = '
