deliveryState abstract method
The wallet's DELIVERY OBLIGATION for one transaction it created (stage S8
obligation) — the same reading a history row carries on
TxSummary.delivery, for the txidHex a send result named. Read it
after a send that was not all-success: only DeliveryState.retryPending
licenses "saved — your wallet will send it on a later sync"; null (not
the wallet's, expired, or no row) and every other state do not.
Implementation
Future<DeliveryState?> deliveryState(String txidHex);
