System Architecture

• Application which uses mDNS to find devices. The protocol to communicate with the devices is websocket.
• UI contains virtual remote controls which sends hex codes over the websocket. The device interprets the hex codes and fires the corresponding IR signal.

Design Patterns

• Code is split between view and controller files.
  • View is only UI.
  • Controller is for business logic and data models.
    • Always extends ChangeNotifier.
• Canvas subpackage uses composite pattern which allows easy extension of custom shapes and whatnot.
  • Custom shapes must extend InteractiveItem.
