Selection Mode States

    • ListView scrolling is disabled
    • Pointer movements update selection ranges
    • Visual indicators may show active selection mode

  • false: Normal operation mode

    • ListView scrolling is enabled
    • Individual checkbox interactions work normally
    • Pointer movements don't affect selection

Usage

  _isSelecting = state;
  notifyListeners();
}
