          alignment: Alignment.bottomCenter,
          child: Column(
            mainAxisAlignment: MainAxisAlignment.end,
            children: [
              GestureDetector(
                onTap: () {
                  // save image to photos directory
                  _save();

                },
                child: Stack(
                  children: [
                    Container(
                      height: 50,
