if you want to build the same design you can do it with the following code

showModalBottomSheet<void>(
                backgroundColor: Colors.transparent,
                context: context,
                builder: (BuildContext context) {
                  return Container(
                    height: 310,
                    margin: EdgeInsets.all(30),
                    child: Column(
                      children: [
                        Container(
                          padding: const EdgeInsets.all(10),
                          decoration: BoxDecoration(
                            color: Colors.white,
                            borderRadius: BorderRadius.circular(15),
                          ),
                          height: 250,
                          child: Column(
                            mainAxisAlignment: MainAxisAlignment.center,
                            children: <Widget>[
                              Text("Sampark"),
