Flutter Firebase Authentication Tutorial - Firebase Auth using email and password 2023

[@rajvi5573]

Great video. Can you also make a tutorial for the Login logic? Your code that I purchased has a lot of things that have not been covered in this tutorial yet and is a bit confusing so will be great if you could explain in a similar fashion as you did for the Sign Up logic. Thanks!

[@user-pm6sw9gt7m]

Workaround for login page logic is to add these lines of code to login_form_widget.dart that was made in previous tutorial that Tea posted. 1. add controllers into LoginForm widget: @override Widget build(BuildContext context) { final controller = Get.put(SignupController()); [...] //EMAIL FIELD TextFormField( controller: controller.email, [...] //PASSWORD FIELD TextFormField( controller: controller.password, [...] 2. Add OnPressed Login Button logic: onPressed: () { FirebaseAuth.instance.signInWithEmailAndPassword( email: controller.email.text.trim(), password: controller.password.text.trim() ); How to show users that info they inputted is not correct is another problem I'm facing now.

[@mrman4636]

add this in your textformfield widget : validator: (value) { if (value == null || value.isEmpty) { return " enter the thing. Idiot!!!"; } else null; } then put your onpressed function in this: if (_formkey.currentState!.validate()) { } so yours will be like: onPressed: () { if (_formkey.currentState!.validate()) { FirebaseAuth.instance.signInWithEmailAndPassword( email: controller.email.text.trim(), password: controller.password.text.trim(); } } ps: _formkey is private hence the underscore

[@user-pm6sw9gt7m]

@@mrman4636 thank you! Only problem is that it only checks if the input field is empty. My problem is comparing data that is input by user with firebase data. Say I am I user and I put in wrong password with one letter/number/symbol missing. The validation above would not show anything to me. Right?

I wanted to take a moment to express my appreciation for your great videos. They have been a valuable resource in my studies. However, I do have a small complaint. I have spent a lot of time going through your playlist, and now I am eagerly waiting for the video on login authentication. Unfortunately, my project evaluation is starting next week, and I am running short on time. I kindly request that you consider creating a video on login authentication before this Saturday or Sunday.

[@CodingwithT]

Hi Ali Haider, thank you so much 🥰. I will create login authentication video soon but you can also send me a message at [phone] for quick fix 😆

Hi sir, first of all thank you very much for this videos , i have question i have test in on real device but there is problem in signup form screen when i pressed on the field the keyboard just show and disappear in less than one second .. can i know why ?

[@Jnims07]

Hello Sir, when I click on a text input field in my app's signup form, the keyboard keeps disappearing repeatedly.

[@evanscott2936]

followed your last video step by step. I did the same for this video. however when initialized the app at 5:00 I did not have a src folder in my lib. what am I doing wrong????????

[@CodingwithT]

If you watch my first tutorials of this course in which I thought about folder structure, then you'll know that src is just a folder nothing else. If you don't have that. Don't worry.

[@maxxy-r3q]

he use flutter_native_splash for the first loaded screen before everything in authcontroller fine

[@ybing2142]

Hi, Sir. The code of userChanges() in video 12:41, it shows "The method 'userChanges' isn't defined for the type 'FirebaseAuth'." for my project. I have upgrade my firebase_auth version but it still the same. May I know any solution for this? and really appreciate for your videos, they help me a lot in my studies.

[@sarkheelmughal6545]

great video. it signup the user successfully but where is the functionality of login screen? how can we send email verification mail

[@CodingwithT]

Email verification is actually a Complete new tutorial, IA i will cover it soon. Whereas you can Login by calling the login function from the auth repository on the login button onPressed

[@abdelbaki343]

hello how can I create a Flutter app with a login interface that allows the user to choose between admin or client login

[@CodingwithT]

Simply create a field in the firebase and name it roles, based on that when the user is authenticated, check its role from the database and redirect accordingly.

[@restaurantrecipebyhafsa]

why I am redirecting to the dashboard without entering the signup details email and password.

[@CodingwithT]

Send me code at [e-mail]

[@skydoesblue4854]

Same issues here

[@restaurantrecipebyhafsa]

@@skydoesblue4854 try implementing the logout functionality. It is just because the user is already logged in to your app so the app redirects the user to its dashboard. So when you will logout the user. it will work fine.

Hi Sir, thank you so much for your videos. But I am facing the error E/flutter (12573): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: Instance of 'signUpEmailAndPasswordFailure'.I have changed the Material App to GetMaterialApp but app is not switching from signup screen to dashboard screen and the problem is same.I will be very thankful for your help.E/flutter (12573): #0 AuthenticationRepository.createUserWithEmailAndPassword (package:flutter_login/src/repository/authentication_repository/authentication_repository.dart:39:4) .This is also alongwith problem.

[@rinkuedutech]

Sir I sort out the issue by replacing "firebaseUser.value!=null ? Get.offAll(()=>dashboard()): Get.to(()=>welcomeScreen());" with "Get.offAll(()=>dashboard()):". May be firebase user value creating problem with "null".

Hallo sir, I got error message like shown: The following message was thrown while handling a gesture: "AuthenticationRepository" not found. You need to call "Get.put(AuthenticationRepository())" or "Get.lazyPut(()=>AuthenticationRepository())", how to solve it, thanks and regards

[@CodingwithT]

As it says, you just have to use the final controller= Get.put(AuthenticationRepository()) It means that you first have to create the instance of any class using Get.put and in the rest of the Classes later on you can use an instance.
