NodeFlowKeyboardHandler<T> class

Primary keyboard handler for NodeFlow using Flutter's Actions and Shortcuts system.

This widget integrates NodeFlow's action system with Flutter's built-in Actions and Shortcuts framework, providing proper keyboard shortcut handling with all the benefits of Flutter's actions ecosystem (menu integration, shortcut manager support, etc.).

Features:

  • Proper integration with Flutter's Actions and Shortcuts system
  • Automatic focus management with optional autofocus
  • Support for custom focus nodes
  • Action enabling/disabling based on controller state
  • Platform-aware shortcut handling (Cmd on macOS, Ctrl on Windows/Linux)

Example usage:

NodeFlowKeyboardHandler(
  controller: nodeFlowController,
  autofocus: true,
  child: NodeFlowCanvas(...),
)
