      FileSystemEntityType.notFound) {
    throw FileSystemException('already exists', destination);
  }
  await (FileSystemEntity.isDirectorySync(source)
          ? Directory(source)
          : File(source))
      .rename(destination);
  emitChange(from, TomFileChangeType.deleted);
  emitChange(to, TomFileChangeType.created);
}
