final class MyEventListener
{
public function __invoke(BeforeFlexFormConfigurationOverrideEvent $event): void
{
// Configuration from TypoScript
$frameworkConfiguration = $event->getFrameworkConfiguration();
// Configuration from FlexForm
$originalFlexFormConfiguration = $event->getOriginalFlexFormConfiguration();
// Currently merged configuration
$flexFormConfiguration = $event->getFlexFormConfiguration();
// Implement custom logic
