Question Can't store result from query from firebase in a var

Hello Y'all! Thank you for reading my post! I'm trying to use Firebase to create a leaderboard for my game.

Code (CSharp):

1. void receiveFirestoreData()
2.     {
3.         Query allUsersQuery = db.Collection("Usernames");
4.         allUsersQuery.GetSnapshotAsync().ContinueWithOnMainThread(task =>
5.         {
6.             QuerySnapshot allUsersQuerySnapshot = task.Result;
7.             foreach (DocumentSnapshot documentSnapshot in allUsersQuerySnapshot.Documents)
8.             {
9.                 Debug.Log($"Document data for {0} document:"+ documentSnapshot.Id);
10.                 Dictionary<string, object> userNamesAndScores = documentSnapshot.ToDictionary();
11.                 foreach (KeyValuePair<string, object> pair in userNamesAndScores)
12.                 {
13.                    
14.                     Debug.Log(pair.Key.ToString() + ", " + pair.Value.ToString());
15.                     Debug.Log($"{0}: {1}"+ $"{ pair.Key}" + $"{(string)pair.Value}");
16.                     userScores.Add(pair.Key.ToString(), pair.Value.ToString());
17.                     Debug.Log("userscore example: " + userScores[pair.Key]);
18.                    
19.                    
20.                 }
21.  
22.                 // Newline to separate entries
23.                 //
24.             }
25.         });
26.     }

I have this function but I haven't been able to get the data retrieved from my firebase database saved to any variable outside this function. That's what userScores is - a dictionary that I was trying to save the key-value pairs from my database to. But the dictionary always is null and Debug.Log() only works where there is no userScores variables. Please help me! How can I make this code work.

 

Reading around, I think perhaps it's a timing issue? the code gets executed before there are any data received? However, the Debug.Log does log key-value pairs so should I be able to put that into a var right away?

 

I managed to figure out that I can assign information from the snapshot to a text variable outside the scope of the function. However, I cannot do the same with a dictionary
