试试用你的纽扣包这个

RawKeyboardListener(
          focusNode: FocusNode(),
          onKey: (RawKeyEvent event) {
            if (event.isControlPressed && event.isKeyPressed(LogicalKeyboardKey.keyP)) {
              // Ctrl+P is pressed
              print('Ctrl+P is pressed');
              // Perform your action here, such as showing a print dialog
            }
          },
          child: Container(
            child: Text('Press Ctrl+P'),
          ),
        )
