sendEventToRelays method

@override Future<void> sendEventToRelays(NostrEvent event, { List<String>? relays, void onOk(String relay, NostrEventOkCommand ok)?, })

This method is responsible for sending an event to all relays that you did registered with the init method.

It takes a NostrEvent object, then it serializes it internally and sends it to all relays WebSockets.

example:

Nostr.instance.relays.sendEventToRelays(event);

Implementation

@override
Future<void> sendEventToRelays(
  NostrEvent event, {
  List<String>? relays,
  void Function(String relay, NostrEventOkCommand ok)? onOk,
}) async {
  await _registerNewRelays(relays ?? relaysList!);

  final serialized = event.serialized();

  if (event.id == null) {
    throw Exception('event id cannot be null');
  }

  _runFunctionOverRelationIteration((relay) {
    final relayUrl = relay.url;

    if (relays?.containsRelay(relayUrl) ?? true) {
      _registerOnOklCallBack(
        associatedEventId: event.id!,
        onOk: onOk ?? (relay, ok) {},
        relay: relayUrl,
      );

      relay.socket.sink.add(serialized);
      utils.log(
        'event with id: ${event.id} is sent to relay with url: ${relay.url}',
      );
    }
  });
}
