Type mixed cannot be marked as nullable since mixed already includes null

[Bahramn]

In PHP 8.0

I got this error:
Type mixed cannot be marked as nullable since mixed already includes null

nova-rating-field/src/Rating.php

Line 43 in 6db4fdf

public function __construct(string $name, $attribute = null, ?mixed $resolveCallback = null)

I just removed the question mark before mixed and it worked.

You can use this, same as the parent class Field

public function __construct($name, $attribute = null, callable $resolveCallback = null)

@martykan How?
We can't make changes in the package's source code so where do you mean to put that line in order to resolve the problem?
