Q & A
What is the main purpose of the app being developed in the video?
-The app allows both admin and user roles to log in through the same login screen, but they are redirected to different screens based on their role.
How does the login system differentiate between admin and user roles?
-After logging in, the system checks the user's role and redirects them to the admin screen if they are an admin or to the home screen if they are a regular user.
What is the role of Firebase in the app?
-Firebase is used for user authentication in the app, allowing users to sign up and log in. Additionally, admin users can fetch and edit data from Firebase based on a user's email.
What is a key feature that the admin role provides in this app?
-The admin can access, edit, and manage user data by entering the user's email. The admin also has the ability to create new users and deactivate existing users.
What precaution does the developer mention about editing user data?
-The developer advises against changing a user’s email because it could break the authentication process if using the same login method as demonstrated.
Why does the developer recommend not saving user passwords in the app?
-Saving user passwords can violate user privacy. The developer only does it for educational purposes in this video but doesn't recommend it for actual use.
How does the admin create new users in the app?
-The admin creates new users by filling out forms with at least an email and password. A button is then used to add the new user to Firebase Authentication.
Why is it important for the admin not to change a user's password from within the app?
-Changing a user's password via the admin controls will not affect the Firebase authentication password, making the change ineffective.
What is the role of the splash screen in the app?
-The splash screen checks whether the user is an admin or a regular user and redirects them accordingly to either the admin or home screen.
Can the admin deactivate users in the app, and how is it done?
-Yes, the admin can deactivate users, but this action must be done through the Firebase Authentication console, not directly in the app.
Outlines
📱 Admin and User Login with Role-based Navigation
The video introduces a Flutter app where both admin and user can log in via the same login screen. Depending on their role, they will be redirected either to the admin screen or the home screen. This video builds on a previous one involving login and signup with Firebase, and the admin role is added. To follow along, viewers should watch the earlier video to understand the existing code. A role field is added to the signup function with a default user role. The splash screen will check the user's role and redirect accordingly.
🔄 Testing Admin Access to User Data
The admin now has the ability to retrieve a user's data by entering the user's email. The video proceeds to demonstrate how to create a screen where the admin can edit user data. There's a minor mistake in the logic, but it's corrected. The admin will be able to continue editing after entering the user's email, and a flag will be set to true. The importance of not changing the user's email is emphasized, especially if using a method similar to the one demonstrated. Password management is briefly discussed, with advice against storing user passwords.
👨💻 Creating and Managing Users as Admin
The admin is shown how to create new users using forms for email and password. The custom method used helps organize users efficiently. In this case, the admin doesn't need to approve new users, since they are created directly by the admin. The video concludes by mentioning that users can be deactivated via the Firebase Auth console. Finally, viewers are thanked for watching, with a promise to include the source code in the video description.

Transcripts
hello everybody welcome back
in this video i will be creating admin
app and flutter so in this app there's
admin and user they can log in with the
same login screen but they will be
redirected either to admin screen or
home screen based on their role this
video idea is from jayamaruganj if you
want your idea to be featured in a video
all you need to do is leave your idea in
the comments section and turn on
notification for my video
anyway let's start this is the app from
the login and sign up with firebase
video and i will be adding admin role to
it
you should watch the previous video to
fully understand the code new role field
need to be added to sign up function and
the default will be the user
next let's create a splash screen and
inside of it will check if user is an
user or an admin
admin will be redirected to admin screen
and user will be redirected to home
screen
[Music]
[Music]
okay let's test this out
[Music]
[Music]
[Music]
there you go now the admin can get the
user's data by entering the user's email
[Music]
now let's create a screen where the
admin can edit the user's data
[Music]
[Music]
[Music]
[Music]
[Music]
yes i made a mistake the user is know
when i click edit user now we need to
create a before when the admin enters
users email and then get the user's data
the bill will set to true so the admin
be able to continue edit the user's data
[Music]
now let's test this one more time
[Music]
there you go now the admin can edit the
user's data little tip from me don't
change the user's email and do it if you
use the same method for login and sign
up as me also i don't recommend saving
users password because it's breaking
users privacy i'm doing it in this video
just for educational purposes also if
you need to save passwords changing it
with admin controls won't change
firebase off password so it will be
useless
[Music]
to let admin create users all you need
to do is create forms with at least
email and password for firebase auth
like this and create a button to create
user in this example i added custom mid
for the users to organize them
in this case i think admin don't need to
approve the user if the admin is the one
who's creating it
you can deactivate user from firebase
auth console
i think that's it thank you for watching
this video
i hope you learned something new today
as always i will put the source code in
the description of this video see you in
the next video
bye bye
