  // 1 means 100% screen size - 0.5 means 50% screen size
  bool isDrawerOpen = false;

  @override
  Widget build(BuildContext context) {
    return Material(
      child: AnimatedContainer(
        duration: Duration(milliseconds: 250),
        transform: Matrix4.translationValues(xOffset, yOffset, 0)
          ..scale(scaleFactor),
        color: Colors.white,
