naddr property

String? get naddr

Encode this event as an naddr (NIP-19 addressable event coordinate)

Only works for coordinate-capable replaceable events. Requires a "d" tag to identify the event.

Returns a bech32-encoded naddr string or null if:

• Event is not addressable/replaceable
• Event doesn't have a "d" tag

Usage: final naddr = event.naddr;

Implementation

String? get naddr {
  // NIP-19 coordinates are valid for parameterized replaceables and
  // singleton replaceable kinds that use an empty d-tag.
  if (!_supportsCoordinate(kind)) {
    return null;
  }

  // Get the "d" tag identifier
  final identifier = getDtag();
  if (identifier == null) {
    return null;
  }

  return Nip19.encodeNaddr(
    identifier: identifier,
    pubkey: pubKey,
    kind: kind,
    relays: sources.isEmpty ? null : sources,
  );
}
