Error: Call to undefined method Drupal\Core\File\FileSystem::uriScheme() in commerce_pricelist_file_download() (line 124 of /var/www/sites/drupal9/web/modules/contrib/commerce_pricelist/commerce_pricelist.module)

Problem/Motivation

When trying to export a pricelist you receive an error in the logs complaining about a deprecated api call when using 9.x
Error: Call to undefined method Drupal\Core\File\FileSystem::uriScheme() in commerce_pricelist_file_download() (line 124 of /var/www/sites/drupal9/web/modules/contrib/commerce_pricelist/commerce_pricelist.module)

Steps to reproduce

export a pricelist, review error in error log when using drupal 9.x

Proposed resolution

resolution was to replace the urlScheme call with

use Drupal\Core\StreamWrapper\StreamWrapperManager;
replace:
$scheme = \Drupal::service('file_system')->uriScheme($uri);
with:
$scheme = StreamWrapperManager::getScheme($uri);

Remaining tasks

Problem remaining is what to do with earlier versions, which still have the api call. Ie anything earlier than 9.x will work as expected, so not sure what is the best course of action here, other than a new release version only compatible with 9.

User interface changes

API changes

Data model changes
