core.Map<core.String, core.dynamic> toJson() => {
      if (columnName != null) 'columnName': columnName!,
      if (customDimensionName != null)
        'customDimensionName': customDimensionName!,
      if (customMetricName != null) 'customMetricName': customMetricName!,
      if (endDate != null) 'endDate': endDate!,
      if (groupByColumn != null) 'groupByColumn': groupByColumn!,
      if (headerText != null) 'headerText': headerText!,
      if (platformSource != null) 'platformSource': platformSource!,
      if (productReportPerspective != null)
        'productReportPerspective': productReportPerspective!,
      if (savedColumnName != null) 'savedColumnName': savedColumnName!,
      if (startDate != null) 'startDate': startDate!,
