I want to add a custom validation rules with parameter and in the Laravel documentation https://laravel.com/docs/5.8/validation#custom-validation-rules there is no validation parameters option. I want a validation rule like required_if.

You can pass it in the constructor
new CustomRule($parameter);
class CustomRule implements Rule
{
public function __construct($parameter)
{
$this->parameter = $parameter;
}
...

You can use sometimes method on validator instance. Use a required rules and add your condition in the function as below:
$v->sometimes('reason', 'required|max:500', function ($input) {
return $input->games >= 100;
});
The example above will check if games are more than or equal to 100, then user will required to have a reason, otherwise it will trigger an error.
The example is from Laravel documentation that you can find here here
