State Management: Flutter Riverpod ( ^3.2.0 ) with clean DAO architecture.

Kitchen Display System (KDS) & Auto-KOT Live Kitchen Screen: Dedicated order display with real-time timers. Auto-dispatches kitchen tickets over thermal network printers. Network Drop Protection: Includes a pre-flight TCP Port 9100 socket probe before sending print jobs to ensure zero lost orders over local Wi-Fi. 3.
