Add isPressed

[aloisdeniel]

As far as I understand the logic, it is not possible to detect the isPressed state of the button.

I would typically use the onTapDown/Up/Cancel events from the gesture detector, but it would be easier if it would be directly provided by this package since it is very common (and would avoid using two GestureDetectors for every buttons)!

class _PressableState extends State<Pressable> {
  bool _isPressed = false;
  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      onTapDown: (e) {
        setState(() {
          _isPressed = true;
        });
      },
      onTapUp: (e) {
        setState(() {
          _isPressed = false;
        });
      },
      onTapCancel: () {
        setState(() {
          _isPressed = false;
        });
      },
      child: FocusableControlBuilder(
         ....
      ),
    );
  }
}

Thanks
