So I am working on a fitness app in flutter with firebase. I have this “freestyles” workout data structure where I am storing the exerciseIds of the exercises done in that workout. They’re being stored in an array “exerciseIds” where the indices are the order that I want. However, in my attempt to pull and retrieve that data back into my code, it is ordering it in alphanumerical order (or unicode order).

So when I pull it back into my code, I want it in order of index (0, 1, 2), but it is arranging to 2,1,0 in this case because that is the “unicode order” (0 – 9, A – Z, a – z) of the exercise ids given that value of index 2 starts with 2, index 1 starts with T, and index 0 starts wit o.

How can I retrieve the data in the indexed order?
Here is where I am pulling it back:

  void _loadActiveWorkout() async {
    if (activeWorkout != null) {
      List<Exercise?> exercises = await exerciseDB.fetchById(activeWorkout!.exerciseIds);
      setState(() {
        exerciseList = exercises;
        itemCounter = exercises.length;
        setCounter = List.generate(exerciseList.length, (_) => 1);
        for (var i = 0; i < exerciseList.length; i++) {
          final exerciseId = exerciseList[i]!.id;
          for (var exercise in activeWorkout!.exercises) {
            if (exercise['exerciseId'] == exerciseId) {
              setCounter[i] = exercise['sets'].length + 1;
              break;
            }
          }
        }
        freestyleId = activeWorkout!.id;
      });
    }
  }

Some of this code may look fairly messy lol (I’m quite beginner level).

I don’t really know how to approach correcting this.
