Firestore User with GetX | Todo App 

Great tutorial for exactly what I was needing to know how to build thanks!

AuthResult is now UserCredential

Thank you for excellent "best practices" guidance! Question: do you use VSC extension to fill "User.fromDocumentSnapshot"? Which extensions do you recommend? Thanks

as always epic work! some of the method and classes here are deprecated but worry not if you use at least android studio it will let you know. i recomend following the docs in FlutterFire along this great video!

that is the great tutorial, but can you share us how to get pagination with getX by using bindstream to append the next list?? please... i'm stuck

Love your videos!! Finally I am at a level to follow along(or maybe just not). Just one question.... when I try your example in flutter null safety I get an error (unexpected null value) and I can’t get me head around it....... instead of Getx in the rootScreen, I am using Obs... it works but for me the logic isn’t clear.... any suggestions? Keep on going with the videos, love them!

Another excellent video on GetX, and now with Firebase it's really getting exciting. Looking forward to see some videos on working with Firestore streams in GetX. Often times we need to combine and manipulate data from 2 or more documents, before we send this off to the view. I've been doing this with BLOC and RxDart up to now, but I guess it will be much less of a pain with GetX. I did some experimenting like this: final videos = List().obs; VideoController() { _videoService = VideoService(); } @override void onReady() async { videos.bindStream(loadVideos()); super.onInit(); } Stream loadVideos() { return _videoService.getAll(); } The controller is Lazy initialized with binding. The view looks like this: body: GetX(builder: (_) { if (_.videos.length == 0) { return Center(child: Text('Nothing to show yet...')); } return ListView.separated( separatorBuilder: (context, index) => Divider( color: Colors.grey, ), itemCount: _.videos.length, itemBuilder: (context, index) { return VideoTile(_.videos.elementAt(index)); }); }), The data shows up fine but does not update in real time if I modify some field in the db. The only way I found to have it update real time is to initialize the Controller in main.dart, but this creates the stream even before I requested it, so it's not very efficient. Imagine an app with dozens of streams getting initialized at startup. So I definitely need to master GetX a bit more and my hope's are on you for now ;-)

Hey Tadas, great series of tutorials - keep up the good work. I managed to follow thorough the Firebase Auth video ok and was able to update it to take into account the Firebase breaking changes but I have a problem with this video and I cannot see how to solve it. I am getting a Exception caught by widgets library - 'Null check operator used on null value' error in the Root() component. I think its the line that checks the user.uid that is the problem but I cannot see how to solve it. Can you help? Ok, so a further check seems to suggest that it is the entire Root() widget not the user.uid check as I first thought. Still stuck :-(

Cool Example. Do you make a example with GraphQL and GetX?. For example Hasura GraphQL works with suscriptions for real-time data changes, and having an example of these would be great. Thank you in advance for so many contributions.

It seems mouse and USB-c hub amazon site url are same. Anyway, always thank you for the great lectures!

Cool stuff!

Hi How are yo im getting this error in the root.dart in the uid is with a red mark builder: (_) { if (Get.find().user?.uid != null) { and give me this error The getter 'uid' isn't defined for the type 'String'. Try importing the library that defines 'uid', correcting the name to the name of an existing getter, or defining a getter or field named 'uid'.

Hi Todas I really enjoyed learning with you but I have a quick. maybe not that quici question. this is all very well for nativa apps in witch you log in and the app stays there. but for web the user can refresh. In my case im loosing the user at usercontroller. my idea is to create the database as Singleton passing the user uid to have it handy for saared data across users that is accessed by the user id at an array. but. the question is. can I somehow watch onAuthStatechange and set both the user at userController and the id at the singleton? maybe im a bit confusing. let me know if you have some time. cheers! and thanks for the amazing guidance

Great video how i can update UserController usercontroller = Get.put(UserController()); because i want reload new info of the user. Thanks

I have been pulling my hair here for several minutes; Why I get squiggly line under AuthResult in the authController file; yelling "undefined class"; any thought btw, I tried to avoid "deprecated" errors, will that be the reason? :) That was the new thing I had to change too for comply with the new version of firebase; AuthResult => UserCredential case solved!!

Tadas impressive about getx but what about a splashscreen do you have to initialize the usercontroller at the same time that the authcontroller? or u will binding with the page ?

hey i have following error: AuthController not found. You need call put(AuthController()) anyone know when / where to call auth controller? If i call it in the wrapper i get a uid even if no user has been created

Hello, whenever i hot restart the data is lost from the UI but its stored in firestore. How do i fix this problem?

I don't mean anything, but most of your tutorial is deprecated :( Could you update them? I may wrong tho, so sorry if I am

By observable you mean notifying to changes right?

Hi, I am getting this error on this line email = doc['email']; [] isnt defined for the type DocumentSnapshot

i am getting The getter 'message' isn't defined for the type 'Object' in catch(e)

Thanks for this, very useful. One thing I'm not sure of - why have you added email to your UserModel (and FireStore)? It's already part of the AuthResult from create or login (with email and password) - authResult.user.email - so no need to store it. Maybe it should still be part of the UserModel for convenience, but no need to store it separately - just initialize it from the AuthResult (save on FireStore data, and read/write counts).

When I write this one👇🏻I get an error, any one can help me please? UserModel.fromDocumentSnapshot(DocumentSnapshot doc) { }

hi tadas, first thanks for the great tutorial it was awesome, simple to understand and it help me allots but the question here comes. am handling roles in my firebase i.e. admin and customer, am trying to manipulate the root so it provide the routes accordingly but it throw an error for me, try implemented this in provider and it works fine but in getx it really confusing, help me out

can you please do firebase storage tutorial

hey thanks for the great video but one question after closing the app and reopening it the user from the usercontroller is always null do i need to do some bindings or what else should I do ?

Help! it says Null check operator used on a null value

In user.dart i can't use the variable id = doc.documentID; And in database.dart there is "Undefined class 'Firestore'." Help

Hi , when i restart app, uid is stay but user.name is not load. i mean , when restarting app, root say, i have uid, go home, but home app bar have infinity loading, not name thanks for tutorial.

With respect, This channel is great but it really hard to learn from you. I would assume this is not a beginner lessons because you change the code between the video without explanation. I would suggest beginners to learn from Codex channel instead.
