I wanna create accounts while I am already logged in.
For example :
I'm logged in as an admin on a website and I wanna create accounts for drivers that work for me and save the uid (in a firebase collection with custom data) or something unique with what I could identify that driver#admin.com is created by admin#gmail.com.
If you want to programmatically create accounts for other users, you'll have to use the Firebase Admin SDK on a backend you control. You won't be able to do this directly from within a mobile app. You'll have to figure out some way to invoke your backend code from within your app. (Explaining all your options here is out of the scope of a Stack Overflow question.)

I'm making a little Snapchat clone, and a part of this app I'm trying to build is the ability to add a friend and start a conversation with them. I'm using Firebase to manage my users and I'm a little stuck now trying to figure out what works and why I'm getting problems trying to use some methods or functions.
What I want is this simple line of code to work:
var userByEmail = await _admin.app().auth().getUserByEmail("b#gmail.com");
print(userByEmail.toString());
However this has been giving my some problems, most recently, the following error message:
Unhandled Exception: FirebaseAuthError(auth/invalid-credential): Must initialize app with a cert credential or set your Firebase project ID as the GOOGLE_CLOUD_PROJECT environment variable to call verifyIdToken().
Getting to this point made me want to first ask a question about FirebaseAdmin and Auth before continuing and potentially screwing up my app settings.
Is there a simple way to do what I'm trying to do?
I have a Firebase.instance.initializeApp() in my Main function, do I only ever call that once or should I start initilizeApp in the initState of each Stateful Widget where needed?
What does this error message actually mean?
You are trying to use the Firebase Admin SDK in your Flutter code, which is not possible. The Admin SDKs give full administrative access to your Firebase project, which would be a serious security concern if you allow that in your Flutter app.
If you want to allow certain administrative functionality in your application, you will have to make that functionality available yourself. For example, to look up a user by their email address, there are two common approaches:
Store the minimal information about each user in a cloud-accessible database (such as Firebase's Realtime Database or Cloud Firestore) when each user registers with your app, and then look it up from there.
Wrap the getUserByEmail from the Admin SDK in a custom API that you make for yourself, on a server you control or in Cloud Functions. In that API you validate that the user making the call is authorized to do so, then call Firebase through the API you were trying to use, and return the minimal result back to the caller.
Both of these are feasible and can work to solve a variety of use-cases. But if you've never built backend code before, you might find the first approach easier to get started with.

The right way to do what you want is using Firebase auth, authenticating your user and using a collection to store and retrieve users information. That auth information provided by firebase should only be used for authentication and security purposes.
The Firebase admin must have a user logged in to work properly, but its purpose is to provide a more administration environment and should not be used inside a clients app, unless its an admin app.
With all that said, lets go for the rescue:
Authenticate your user (using firebase auth);
After auth, save all the user information you want to share with other user inside its own collection (you will need to create one);
When an authenticated user (this is important) 'request any other users data, you query for the data in the previous created collection.
I am using Firebase Authentication in my app. I used method like setDisplayName in my app so that user can change the user's name himself through the app. But, the problem is that I can't access this name through my console. I can't edit it. There are simple columns in Firebase console like,
identifiers,providers,UID,Providers,Signed In.
There is no column for User Name. How can I access this information through console?
The Firebase console shows only limited information about each user profile. The rest of the information is only available when you access the profile through a Firebase API, or export the data.
Keep in mind that Firebase provides Admin SDKs, which you can run on your development machine to accomplish simple administrative tasks such as this.
I have a Firebase project, which I'm currently using with android. I need to programmatically fetch details of the users authorized along with the UID, Email, etc. Exactly the way it is shown in firebase (with the search), this web portal will be given to the vendor or the person using it to verify the user's authenticity.
I've attached the screenshot from Firebase, I'm hoping to replicate it the same way with the search. If this is possible, how do I go about doing this?
It's not possible to list users from an Android app, using only the Firebase Authentication SDK. You can list users using the Firebase Admin SDK, but that can only be run on a backend you control, using service account credentials for your project.
It might be easier if you store user info in a database, to be queried by client code, rather than try to have your app try to access auth data directly.
I'm working on an enterprise application in which administrators create new users (there is no sign-up form). I am using Firebase Auth, which is great in many ways, but I've come across a problem for my use case. When you use firebase.auth().createUserWithEmailAndPassword(email, password), the user thereby created is automatically signed in. This obviously won't work when an admin is creating the user accounts. Is there any way to avoid this behavior? Thanks.
This is a good use case for the Firebase Admin SDKs. Instead of creating the user client-side, you create the user in a managed environment, like a server or Cloud Functions. You have the client make a call to your endpoint when you want to add a new user. This codelab shows how to incorporate custom claims using the Firebase Admin Auth SDK. This is a little different from what you're exactly looking for, but it can get you started in the right direction.
Using Firebase I want to create different groups of users (i.e. users, admins etc) for my app. I've created some users via the console but I'm trying to find out if it's possible to assign roles to these users via the console too?
After some reading on their website firebase recommends using custom claims which can be encoded within a user's access token. This sounds perfect but the only way I can find to issue such claims is coding an app to access the admin SDK. Is there any way to achieve the same functionality but via the firebase console instead?
