  }

  final original = Map<String, Object?>.from(originalRow);
  final originalDisplay = JsonViewUtils.prepareRow(original);
  final updated = Map<String, Object?>.from(updatedRow)..remove('_rowid_');

  final validationError = _validateRowUpdate(original, updated);
  if (validationError != null) return validationError;

  final changedColumns = <String>[];
  for (final key in originalDisplay.keys) {
    if (!updated.containsKey(key)) continue;

    }
  }

  if (changedColumns.isEmpty) return null;

  try {
