isRevokedRequest method
Whether request is one the entry's mount grace revoked — the same
request under sameSendRequest — and therefore must not pay through a
bare door (a re-navigation with the request alone, in place or on a fresh
mount). The screen reads this for a bare request; a request that arrived
on a live channel is answered by the channel, not by this memory.
Implementation
bool isRevokedRequest(WalletSendRequest request) =>
_revokedRequests.any((revoked) => sameSendRequest(revoked, request));
