{
    /**

        && method_exists($model->present(), $method = $this->presenterMethod($field))
            ? [$model->present(), $method]

It seems like value() must be provided by classes using this trait. How about adding it as abstract method to this trait?

    }

    /**
     * @param string $fieldName
     * @return string
     */
    public function presenterMethod(string $fieldName): string
    {
        return 'admin'.title_case(camel_case($fieldName));
    }
}
