I started using PHPStan with the WordPress Plugin Boilerplate project that can be found here.
I am stuck in the class-plugin-name-loader.php file validation
I solved these errors:
33 - Property Plugin_Name_Loader::$actions type has no value type specified in iterable type array.
42 - Property Plugin_Name_Loader::$filters type has no value type specified in iterable type array.
By replacing array with mixed[]
When I increase the rule level to 7, these validation errors appear:
120 - Parameter #2 $callback of function add_filter expects callable(): mixed, array{mixed, mixed} given.
124 - Parameter #2 $callback of function add_action expects callable(): mixed, array{mixed, mixed} given.
How do I fix this error?
My code relative to class-plugin-name-loader.php file:
/**

*
* @link http://example.com
* @since 1.0.0
*
* @package Plugin_Name
