I'm displaying a request list from the database, and when a request created I got an error before displaying it, i thought the error was because of the null i added condition to check and it did not work also

this is my code

 UserCubit.get(context).requestFriends.isEmpty
                ? Container(
                
                child:
                Center(child: Text('You have no requests')))
                : Container(
              height: height * 0.3,
              child: Flexible(
                child: ListView.separated(
                    itemBuilder: (_, index) {
                     
                      return Container(
                        child: Row(
                          children: [
                              
                            Text(
                                "${UserCubit.get(context).requestFriends[index]['nameSender']}"),
                            
                      );
                    },
                    separatorBuilder: (_, index) {
                      return Padding(
                        padding: const EdgeInsets.symmetric(
                            horizontal: 20),
                        child: Divider(
                          thickness: 1,
                          color: lightgrey,
                        ),
                      );
                    },
                    itemCount: UserCubit.get(context)
                        .requestFriends
                        .length ==
                        0
                        ? 1
                        : UserCubit.get(context)
                        .requestFriends
                        .length),

and here a pic of the error

Problem is that you are giving giving itemcount as 1 when the length is 0.

Try Changing the itemCount from

itemCount: UserCubit.get(context)
                        .requestFriends
                        .length ==
                        0
                        ? 1
                        : UserCubit.get(context)
                        .requestFriends
                        .length

to

itemCount : UserCubit.get(context)
                        .requestFriends
                        .length

Problem is Here

UserCubit.get(context).requestFriends[index]['nameSender']

You can't use ['nameSender'] after index. just decode it before using it. Hope it helps
