Description

If a class property is used only to create an instance of an anonymous class, it is marked with an 'Unused' hint.

The example code is below. There is also an image attached with a screenshot, note how $anyParameter in Factory1 constructor is underlined. This goes for both constructor argument promotion and the PHP7-style property declaration.
 

<?php declare(strict_types = 1);

namespace Cz\Test\UsedProperty;

class Factory1
{
    public function __construct(private bool $anyParameter)
    {
    }

    public function create(): Interface1
    {
        return new class ($this->anyParameter) implements Interface1
        {
            public function __construct(private bool $parameter1)
            {
            }

            public function getSomeParameter(): bool
            {
                return $this->parameter1;
            }
        };
    }
}


interface Interface1
{
    function getSomeParameter(): bool;
}
