PHP 7.2 error

Getting an error with plugin:

PHP Warning:  count(): Parameter must be an array or an object that implements Countable in /var/www/blog/wp-content/plugins/multiline-files-for-contac
t-form-7/multiline-files-upload-for-contact-form-7.php on line 184" while reading response header from upstream

Changing the line 184 from
$total = count($_FILES[$name]['name']);
to

if (empty($_FILES)) $_FILES = [];
$total = count($_FILES[$name]['name']);

Fixes the issue ??
