Marks a data object as signal for the workflow of the element type T.
Implement it on a signal class to be able to send it: only signals of the
right element type are accepted by Workflow<T>.send.
A signal tells a workflow about something that happened outside of it, for
example a payment provider calling a webhook. It is handled by an
OnSignal step and sent with Workflow.send.
Signals are stored until the workflow handled them, so they have to be data objects:
@Data()
class PaymentSignal extends $PaymentSignal
implements WorkflowSignal<Invoice> {
const PaymentSignal({required this.invoiceId});
final String invoiceId;
}
