Implementation

@override
void closeEventsSubscription(String subscriptionId, [String? relay]) {
  final close = NostrRequestClose(
    subscriptionId: subscriptionId,
  );

  final serialized = close.serialized();

  if (relay != null) {
    final registeredRelay = nostrRegistry.getRelayWebSocket(relayUrl: relay);

    registeredRelay?.sink.add(serialized);

    utils.log(
      'Close request with subscription id: $subscriptionId is sent to relay with url: $relay',
    );

    return;
  }
  _runFunctionOverRelationIteration(
    (relay) {
      relay.socket.sink.add(serialized);
      utils.log(
        'Close request with subscription id: $subscriptionId is sent to relay with url: ${relay.url}',
      );
    },
  );
