ComponentInputHandler class Focus Input

Routes input events to the currently focused interactive component.

This InputHandler queries the provided FocusManager for the component currently in focus, then forwards input events to that component’s own input handler.

If no component is focused, or the focused component does not handle the event, this handler returns an ignored ResponseInput.

Example

final focusManager = FocusManager(context: appContext);
final inputHandler = ComponentInputHandler(focusManager);

// When an input event arrives:
ResponseInput response = inputHandler.handleInput(inputEvent);
if (response.handled) {
  // Update UI accordingly
}
