Can't get getCustomer() in custom event

Question

If I observe customer_save_after event I can get information about the customer with $customer = $observer->getEvent()->getCustomer();.

However, if dispatching my custom event instead of customer_save_after I get

Error: Call to a member function getDataModel() on null

when I try to get it like $customerData = $customer->getDataModel();

I think this is because I can't even get getCustomer() in an custom event.

Is there anything I could do to get the same data as from customer_save_after?

Edit: custom dispatch

public function afterAddCustomer()
    {
        $this->eventManager->dispatch(
            'myname_customer_save_after',
            ['block' => $this]
        );
    }

Edit2: Changed the dispatcher but now I get

Error: Call to undefined method Vendor\Module\Plugin\Model\EventCompanyAccount::getDataModel()

I think getDataModel() method can be found in \Magento\Customer\Model\Data\AttributeMetadata.php but extending my class does not fix the error.

Answer 1

Either you fix the custom dispatcher like:

public function afterAddCustomer()
{
    $this->eventManager->dispatch(
        'myname_customer_save_after',
        ['customer' => $this]
    );
}

OR Use the following code in the listener:

$observer->getEvent()->getBlock()
