sendAgain method

Future<String?> sendAgain({ String? txid, })

Try to send this event again. Only works with events of status -1. If this is a file event and the file was not uploaded yet and the file is not found in the cache locally, this throws a FileNoLongerInCacheException.

Implementation

Future<String?> sendAgain({String? txid}) async {
  if (!status.isError) return null;

  // Retry sending a file:
  if ({
    MessageTypes.Image,
    MessageTypes.Video,
    MessageTypes.Audio,
    MessageTypes.File,
  }.contains(messageType)) {
    final file = await _getCachedFile();
    final thumbnail = await _getCachedFile(getThumbnail: true);
    if (file == null) throw FileNoLongerInCacheException();

    final credentials = FileSendRequestCredentials.fromJson(unsigned ?? {});
    final inReplyTo = credentials.inReplyTo == null
        ? null
        : await room.getEventById(credentials.inReplyTo!);
    return await room.sendFileEvent(
      file,
      txid: txid ?? transactionId,
      thumbnail: thumbnail as MatrixImageFile?,
      inReplyTo: inReplyTo,
      editEventId: credentials.editEventId,
      shrinkImageMaxDimension: credentials.shrinkImageMaxDimension,
      extraContent: credentials.extraContent,
    );
  }

  // we do not remove the event here. It will automatically be updated
  // in the `sendEvent` method to transition -1 -> 0 -> 1 -> 2
  return await room.sendEvent(
    content,
    txid: txid ?? transactionId ?? eventId,
  );
