Cake\View\ViewBuilder::setClassName(null) docblock Update Needed

[challgren]

This is a (multiple allowed):

• bug

• enhancement

• feature-discussion (RFC)

• CakePHP Version: 3.6.14.

• Platform and Target: PHP 7.2.12, PHPStan 0.10.6.

What you did

My code contains a simple $this->viewBuilder()->setClassName(null); in a controller to not render a view.

What happened

PHPStan emits an error Parameter #1 $name of method Cake\View\ViewBuilder::setClassName() expects string, null given.

What you expected to happen

No error to be emitted since the ViewBuilder->$_className is declared as @var string|null the docblock for ViewBuilder::setName($name) should be updated with @param string|null $name The name of the view.
