>Solution :

You can wrap your image in a ClipRRect.

Row(
            children: [
              Expanded(
                flex: 0,
                child: Container(
                  decoration: BoxDecoration(
                      color: whiteColor.withOpacity(0.4),
                      border: Border(
                        bottom: BorderSide(
                          color: greyColor,
                          width: 1.7,
                        ),
                      )

                  ),
                  child: InkWell(onTap: () {
                    _onPressedShowBottomSheet();
                  },
                    child: Row(
                      children: [
                        ClipRRect(
