I am trying to implement a bottom sheet. I used showModalBottomSheet. I need to change the drag handle color of that bottom sheet.

showModalBottomSheet(
                context: context,
                showDragHandle: true,
                backgroundColor: Colors.transparent,
                builder: (context) => Container(
                  height: screenHeight * 0.25,
                  width: screenWidth,
                  decoration: const BoxDecoration(
                    color: Colors.white,
                    borderRadius: BorderRadius.only(
                      topLeft: Radius.circular(25.0),
                      topRight: Radius.circular(25.0),
                    ),
                  ),
                  child: const Center(
                    child: Text("Modal content goes here"),
                  ),
                ),
              );
