When is it dispatched?

Dispatched just before a controller is called.

Use cases

Configure the arguments passed to the controller (e.g., map URL route params to the corresponding named arguments or pass the current request object when the Request type-hint is used).

Example

use Symfony\Component\HttpKernel\Event\ControllerArgumentsEvent;

public function onKernelControllerArguments(ControllerArgumentsEvent $event)
{
    // ...

    // get controller and request arguments
    $namedArguments = $event->getRequest()->attributes->all();
    $controllerArguments = $event->getArguments();

    // set the controller arguments to modify the original arguments or add new ones
    $event->setArguments($newArguments);
}
