inFlightSendFixture function
An in-flight two-step row (#309) — first leg broadcast, send not complete; drives the durable "on its way — don't send it again" cue.
Implementation
InFlightSend inFlightSendFixture({
int amountZat = 80000,
int createdAt = 1700000000,
}) {
return InFlightSend(amountZat: amountZat, createdAt: createdAt);
}
