Shopware How to get SalesChannelContext in OrderWrittenEvent in order to send Mail? - shopware

Question

I have a situation where I want to send emails from the order written event whenever an order has been updated according to some set of conditions that I will implement (for example an API response error) But unfortunately I have been unable to do so.
I first created a controller and an email service which uses the abstract email service of shopware And from my controller I'm able to send an email But when I tried to do the same in the event,I quickly realized that it wasn't doing exactly what I was expecting it to do. After some research on it, I saw that the event actually don't have access to the sales channel context so I tried multiple different ways to solve this issue but I'm still stuck. Can somebody please guide me on how I can implement that? thank you very much.
an example of what I tried is to call the store API in order to get the context of the saleschannel to use it in my sendMail function But it was giving errors such as:
request.CRITICAL: Uncaught PHP Exception TypeError: "Argument 5 passed to Swag\BasicExample\Service\EmailService::sendMail() must be an instance of Shopware\Core\System\SalesChannel\SalesChannelContext, instance of stdClass given.
I obviously understand that I have to give it a Shopware\Core\System\SalesChannel\SalesChannelContext not an STD class but how can I do that? since it doesn't really see the channel context.

If you do have an instance of OrderEntity you can rebuild the SalesChannelContext from the existing order using the OrderConverter service.
<service id="Foo\MyPlugin\Subscriber\MySubscriber">
<argument type="service" id="Shopware\Core\Checkout\Cart\Order\OrderConverter"/>
<argument type="service" id="order.repository"/>
<tag name="kernel.event_subscriber"/>
</service>
class MySubscriber implements EventSubscriberInterface
{
private OrderConverter $orderConverter;
private EntityRepository $repository;
public function __construct(
OrderConverter $orderConverter,
EntityRepository $repository
) {
$this->orderConverter = $orderConverter;
$this->repository = $repository;
}
public static function getSubscribedEvents(): array
{
return [
OrderEvents::ORDER_WRITTEN_EVENT => 'onOrderWritten',
];
}
public function onOrderWritten(EntityWrittenEvent $event): void
{
foreach ($event->getWriteResults() as $writeResult) {
$orderId = $writeResult->getPrimaryKey();
$criteria = new Criteria([$orderId]);
$criteria->addAssociation('transactions');
$criteria->addAssociation('orderCustomer');
$order = $this->repository
->search($criteria, $event->getContext())->first();
if (!$order instanceof OrderEntity) {
continue;
}
$salesChannelContext = $this->orderConverter
->assembleSalesChannelContext($order, $event->getContext());
// ...
}
}
}
