  this.backgroundColor,
  this.onExpansionChanged,
  this.children = const <Widget>[],
  this.initiallyExpanded = false,
  this.themeData,
}) : super(key: key) {
  themeData ??= FormItemConfig();
  themeData = BaseThemeConfig.instance
      .getConfig(configId: themeData!.configId)
      .formItemConfig
      .merge(themeData);
  themeData =
      themeData!.merge(FormItemConfig(backgroundColor: backgroundColor));
