ContainerGetToConstructorInjectionRector

Turns fetching of dependencies via $container->get() in ContainerAware to constructor injection in Command and Controller in Symfony

 final class SomeCommand extends ContainerAwareCommand
 {
+    public function __construct(SomeService $someService)
+    {
+        $this->someService = $someService;
+    }
+
     public function someMethod()
     {
         // ...
-        $this->getContainer()->get('some_service');
-        $this->container->get('some_service');
+        $this->someService;
+        $this->someService;
     }
 }

use Rector\Symfony\Symfony42\Rector\MethodCall\ContainerGetToConstructorInjectionRector;

return RectorConfig::configure()
    ->withRules([
        ContainerGetToConstructorInjectionRector::class,
