On search with "before" param: BAD Command Argument Error. 11

[ig-garcia]

It looks like the querybuilder may be adding too many double quotes to the dates?

My error:

param: BAD Command Argument Error. 11

My use case:

final cutoffDate =
        (await _localDataSource.getOldestMessage())?.decodeDate()!;
    final List<MimeMessage> newMessages;
    if (cutoffDate != null) {
      final searchResult = await mailClient.searchMessages(
          MailSearch("", SearchQueryType.subject, before: cutoffDate));
