Implementation

@override
Future<List<SmartDateQueryResult>> filter(
    String? query, List currentSelections, int limit) async {
  if (query.isNullOrBlank) {
    final location = sunnyLocalization.userLocation;
    final defaultResults = [
      /// Then, process the expressions
      for (final expression
          in config.defaultDates.whereType<DateExpression>())
        SmartDateQueryResult.ofDateTime(expression.dateProducer(location!),
                icon: expression.iconName, overrideLabel: expression.title)
            .withDateRef(expression),

//        /// First, process all the MetaDates
//        for (final metaDate in config.defaultDates.whereType<MetaDateRef>())
//          for (final factDate in await _smartDateService.resolveMetaDateResults(
//              refs: [metaDate],
////              contact: config.contact,
////              facts: config.facts,
//              location: location))
//            factDate.withDateRef(metaDate),

      /// Lastly, the query expressions
      for (final query in config.defaultDates.whereType<SimpleDateQuery>())
        for (final queryResult in await _filter(query.query, [], limit))
          queryResult.withDateRef(query),
    ];
    return defaultResults;
  } else {
