                      builder: (BuildContext context, AsyncSnapshot<List<Cards>> snapshot) {
                        return SizedBox(
                          width: 40.w,
                          child: Column(
                            children: snapshot.data!.map((cards) {
                              return SizedBox(
                                width: 40.w,
                                child: RaisedButton(
                                  color: Color(0xffBE4E49),
                                  textColor: Colors.white,
                                  shape: RoundedRectangleBorder(
                                      borderRadius: BorderRadius.circular(10)),
                                  onPressed: () async {
                                    // null;
                                    setState(() {
                                      DatabaseHelper.instance.remove(cards.id!);
                                    });
                                    Navigator.pushAndRemoveUntil(
                                      context,
                                      MaterialPageRoute(
                                          builder: (_) => new HomeScreen()),
                                          (Route<dynamic> route) => false,
                                    );
                                  },
                                  child: Text(
                                    'DELETE',

                              );
                            }).toList(),
                          ),
