FromUriRector

Fixes deprecated file_create_url() calls from \Drupal\Core\Url::fromUri().

-\Drupal\Core\Url::fromUri(file_create_url($uri));
+\Drupal::service('file_url_generator')->generate($uri);

Configure your rector.php:

<?php

use DrupalRector\Drupal9\Rector\Deprecation\FromUriRector;
use Rector\Config\RectorConfig;

return RectorConfig::configure()
    ->withRules([
        FromUriRector::class,
    ]);
