                  ),
                  TableCell(
                    child: Center(child: Text(user.score)),

                  TableCell(
                    child: Center(child: Text(user.email)),
                  ),

You can try this solution.

() async {
          SharedPreferences prefs = await SharedPreferences.getInstance();
          log(prefs.getKeys().map((e) => e.runtimeType));
          List<String> keys = prefs.getKeys().toList();
          log(keys);
          List<Object> userDataList = [];
          for (String key in keys) {
            Object? userData = prefs.get(key);
            userDataList.add(userData!);
          }
          log("userDataList ${userDataList.length}");
           {
            users.add(User(
              name: userDataList[0],
              score: userDataList[1],
              email: userDataList[2],
            ));
            print("length " + userDataList.length.toString());
          }
          return;
        }

You can add the condition in between the loop.
