When is it dispatched

Dispatched after the control has been resolved but before it’s executed.

Use cases

Initialize things later needed by the controller (e.g., param converters).
Change the controller entirely.

Example

use Symfony\Component\HttpKernel\Event\ControllerEvent;

public function onKernelController(ControllerEvent $event)
{
    // ...

    // the controller can be changed to any PHP callable
    $event->setController($myCustomController);
}

List event listeners
