QUESTION
I'm doing a Group Chat with Firebase and currently I'm using a RecyclerView to display chat messages and I'm having a problem. When you open the app in the fragmented home and you go to chat activity and start chatting (adding elements to recycler view) all goes fine. But, when you go via the NavigationDrawer to another fragment and get back to the chat fragment using again this Navigation Drawer. When you add one element in the chat it appears all in the blank it just displays the last message. Anybody knows why does this happens?
Here I leave the RecyclerView Adapter Code:

QUESTION
So over the past few weeks I have been testing out FirebaseAuth both for the web and Android and the experience has been mostly bad. I have tried to add as much information as I can to give you enough context.
My Goal
My EndGoal is to make a package to simplify FirebaseAuth in Flutter Basically, the StreamBuilder runs on the authStateChanges stream from FirebaseAuth, It gives a user immediately after signIn or when I reload the whole page (Flutter Web) but doesnt return a user during hot reload eventhough I know the user has been authenticated. It works again when i reload the webpage. This does not exist in Android and it works as expected. Its very frustrating, and i could use some help from anyone!

Answered 2021-Jun-03 at 12:01I just Found a Solution to this problem! Basically the FireFlutter Team had fixed a production level bug and inturn that exposed a flaw of the Dart SDK. As this was only a Development only bug (bug only during Hot Restart), it was not given importance.
In my Research I have found that the last version combination that supports StreamBuilder and Hot Restart is
firebase_auth: 0.20.1; firebase_core 0.7.0
firebase_auth: 1.1.0; firebase_core: 1.0.3
These are the only versions that It works properly on. Every subsequent version has the new upgrade that has exposed the bug.
The Solution is very Simple! Works for the latest version (1.2.0) of the firebase_auth and firebase_core plugins too!

QUESTION
This article mentions:
If your app includes a custom backend server, ID tokens can and should be used to communicate securely with it. Instead of sending requests with a user’s raw uid which can be easily spoofed by a malicious client, send the user's ID token which can be verified via a Firebase Admin SDK (or even a third-party JWT library if Firebase does not have an Admin SDK in your language of choice). To facilitate this, the modern client SDKs provide convenient methods for retrieving ID tokens for the currently logged-in user. The Admin SDK ensures the ID token is valid and returns the decoded token, which includes the uid of the user it belongs to as well as any custom claims added to it.
From learning on Youtube, the raw uid
always seems to be used.
Eg:
...ANSWER
Answered 2021-Jun-13 at 00:45The UID of a user is a unique, constant identifier for that user. So if the same user logs in multiple times, they'll get the same UID.
It makes no sense to use the ID token as the identifier for the user in the database, as an ID token will change every hour.
You should continue to use the UID to identify the user, and only use the ID token when you need to verify the user's identity.
QUESTION
I am calling class method which is in a different file from the main method of main.dart. Here I am trying to get the session status of the user. I am not sure what I am doing wrong, the return value always returns false when called in from the main method, but returns true if printed out in the actual method.
Here the expected result is true as the user is currently in the system and is signed in.
Here is my main method -
...ANSWER
Answered 2021-Jun-12 at 21:43You can't check if the user is logged with FirebaseAuth.instance.authStateChanges()
, since this method only notifies when the user status changes.
You can use the FirebaseAuth.instance.currentUser
property instead:

QUESTION
Why am I getting null? Why is the phone number transmitted, but not the usual string? I've been working on this problem all day, please help.
...ANSWER
Answered 2021-Jun-11 at 17:06This part :
\"phone\": "+getPhoneNumber_str+",\n
needs to be :
\"phone\": \""+getPhoneNumber_str+"\",\n
You need to create escaped quotes between the variable for correct concatenation.
QUESTION
I'm developing a post like system. For posts I am using the following structure:
...ANSWER
Answered 2021-Jun-11 at 14:46If you want to add all uid under "postLike" collection that is impossible .because You can't store field(uid) in collection(postLike). you can only store field under document.but if you want you can store all uid under "postId" document.
so when user double tap on like, add document "addLike" as you mentioned in your question. when another user double tap on like update document under "postLikes".so that you can keep all uid under one document.
