stringifyExtraProperties static method

HashMap<String, String> stringifyExtraProperties(HashMap<String, TBLExtraPropertyWithLevel> pageExtraProperties)

Converts extra properties with levels to JSON-encoded strings. Properties that fail to encode are skipped and logged.

Implementation

static HashMap<String, String> stringifyExtraProperties(
    HashMap<String, TBLExtraPropertyWithLevel> pageExtraProperties) {
  return HashMap.fromEntries(
    pageExtraProperties.entries.map((entry) {
      try {
        final key = entry.key;
        final value = entry.value;
        final jsonString = jsonEncode(value.toJson());
        return MapEntry(key, jsonString);
      } catch (e) {
        // Log error and skip this property by returning null
        TBLLogger.logException(
            "TBLPropertiesUtils | stringifyExtraProperties | Error encoding property ${entry.key}: $e");
        return null;
      }
    }).whereType<MapEntry<String, String>>(),
  );
}
