Thank you 😀✌️

Expected a volue of type String', but got one of type 'Null' I face this error

[@CodingwithT]

It means a variable which is expected to receive a String but somehow you passed null to it. If it's being fetched from the Firestore you can add ?? ''; Next to the value and it means if the variable received null, assign an empty string to it.

When exactly will we get the onboarding screen now? Because if I start the application from start, the credentials are still saved & I'm not getting the onboarding screen like before.

[@CodingwithT]

The onboarding screen appears only for first-time users. To see it again, you can clear the saved credentials or reset the app's shared preferences

Hi you create the input decoration of the textfieldform how to use this in it?

[@CodingwithT]

To use the custom input decoration in a TextField or TextFormField widget, you simply need to pass it as the value for the "decoration" property. If you have any further questions or need assistance, feel free to ask!

[@shahzaibmehmood65]

Thanks

[@Rivero727]

When is the logout function applied? In the previous video it was created but it cannot be used.

[@CodingwithT]

You can add that in the settings screen. Create the button and call that function.

Thank you! Glad you enjoyed it!

Best series but i have one problem after the onboarding screen when i go to the login screen theres the logo and texts but on the bottom that theres a huge grey box thats covering almost the whole screen, please help

[@CodingwithT]

Thanks for the feedback! 😊 It sounds like there might be a layout or widget issue causing the grey box to appear. Try checking the layout structure on the login screen. If the issue persists you can contact us on Whatsapp.

[@taku_and_jesus]

@@CodingwithT so the problem is not in the login form

[@taku_and_jesus]

Can u help me with this, when i signup and i back to sign in, it get bug multi global key in widget tree, i dont know to fix it

[@CodingwithT]

It is because you are using same global keys for two or more forms. Check it thoroughly and let me knowif it didn't solve your issue.

Sir, android emulator works very well, but the Ios emulator ‘IconButton’ and ‘remember me’ part does not work, even the login button still redirects directly to the homepage. What could be the reason?

[@CodingwithT]

Make sure the code is same and also debug it as there is no such specific thing for android and iOS.

[@maxxy-r3q]

hello sir, why do I have after login even ask for email verification again? even though previously when registering an account it was already verified

[@CodingwithT]

It sounds like there might be a navigation issue in your application. After a successful login, the app should ideally navigate to the appropriate screen or route based on the user's authentication status. It's possible that the navigation logic might need to be reviewed and adjusted to ensure a seamless user experience. Have you checked the navigation flow in your code to ensure that it correctly handles authenticated users?

Nothing to worry about. Just add ?? ""; next to your both local variables. This error is saying that you are accessing null and assigning null to the String.

Hi! Please make sure to check the steps you're following and ensure everything is implemented correctly. If the issue persists, try debugging the code to identify the root cause. Let me know if you need further assistance! 😊

[@phantuoi_it_247]

I think you made a mistake by placing the "key: controller.loginFormKey" in the Padding not in the Form of LoginForm

[@zisouh710]

I have error they give me "Type 'null' is not a subtype 'string'" Pleeaaase help me

[@CodingwithT]

In the model file. when you are getting data using fromSnapShot you have to use ?? ' ' while assigning the data. Like UserModel( id: document.id, firstName: data['FirstName'] ?? '', lastName: data['LastName'] ?? '', username: data['Username'] ?? '', email: data['Email'] ?? '', phoneNumber: data['PhoneNumber'] ?? '', profilePicture: data['ProfilePicture'] ?? '', ); If this did not work, then you have to debug the code. This error means that it want some value in string but it is returning null

[@CodingwithT]

Wa Aleykum Assalam! 🌟 Please try debugging your code first to see if there are any errors or warnings being logged. Check if the loginWithEmailAndPassword function is properly implemented and verify the backend settings (e.g., Firebase configuration). Debugging will give you a clearer idea of where the issue might be. 🔍 Let me know what you find! 😊
