Try watching with captions turned on.

Actually have not written give me some time will write ✍️

@@indianappguy thanks... God bless you!! You deserve you cup of coffee👍👍

Future getUserByName(String username){ return Firestore.instance.collection('users').where("name", isEqualTo: username).getDocuments(); } use that code

Thank you so much 🙂 do check out other videos i have on the channel i am sure you will find many quite helpful

this basically means that your program is trying to print data before actually getting or completing the operation of getting the data. I also faced this once and I ended up using two nested future builders to solve the problem - one for only rendering when the data is received and the other for confirming that data is not null and rendering the page.

replace searchSnapshot.docs[index].data["name"] with searchSnapshot.docs[index].data()["name"] ^ add this a firebase update caused that issue

@@itaintcal in 01:04:30 it gives me exception handling that (type 'String' is not a subtype of type 'QuerySnapshot' in type cast) if I give searchsnaphot = val as QuerySnapshot and if I give searchsnapshot = val then it give me error at val and show String' can't be assigned to a variable of type 'QuerySnapshot'....help me in this if you have knowledge regarding this

@@itaintcal this isn't working

@@itaintcal now it gives null error

I am glad you liked it do share

@@indianappguy have doubt im not getting sendBy value Constants.myName always coming empty can you explain this

Make sure the key is same in your database when uploading

Need to see code to tell more in details

@@indianappguy I got it. Thank you so..much. Ur really awesome,🤗

Thanks Baran

did you solve it yet ?

i have a same problems :(

@@namthuannguyen8332 yes.. define searchsnapshot as below QuerySnapshot? searchSnapshot; this has resolved the issue for me.

@@nature__filters7029 I tried everything and still didn't work for me, can you take a look at my code?

@@fedybelaid4358 yeah sure.. can you share the code?

hi, did you manage to resolve it?

check console its new query you need to create it in firestore

Still facing the issue?

It happens with all of us just give it time

okay

This is the best option with firebase database

thanks Pavan do share

inkwell have this ripple effect of material design while gesture detector does not so depending on what you like you can use inkwell as well i will suggest to go give it a try just change Geaturedetector with inkwell and run the code and see yourself

check this on ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2d1fslyxBjQ.html

Always welcome

Please make sure the email id and Password is created in Firestore before its passed through the Form. The instructor missed this step and was not much clear on this. And make sure to use print(${val.userId}) in signup.dart

@@soumyasouravpatnaik2246 broh im facing this error too but dont know how to resolve it

sure you can run two functions and return the data from both, that way you can have a fucntion which make a search via username and other via email does that answer your questions?

change late QuerySnapshot searchSnapshot to late QuerySnapshot searchSnapshot;

I am having the same issue, could you help me out?

@@mostcoca thank you

this is old now check ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2d1fslyxBjQ.html

Have you added the SearchList() inside of the Column?

Bro i am facing same problem now please help me if you solved this issue..

Same problem

Mam did it work for you?

@@sudhvinaas3197 Hi I didn't make the chat part just the firebase connection . Are u having issues in solving the errors?

@@tulikatayal9062 Yeah mam

@@tulikatayal9062 Actually I completed almost last 2 errors were there,I had problem with emulator as well as device ,couldn't see output at all.By making trial and error to fix it, from two errors it has increased to more suddenly. I don't know what to do now😳

@@sudhvinaas3197 😂debugging is always the problem what were the errors?

Add .trim() in your email

I am glad you liked it

Widget searchList() { return ListView.builder( itemCount: searchResultSnapshot.docs.length, itemBuilder: (context, index) { return SearchTile( userName: searchResultSnapshot.docs[index].data()["name"], userEmail: searchResultSnapshot.docs[index].data()["email"], ); }); } CHANGE TO THIS

@@divyanshgupta748 thanks i have alreadysolved this and updated in the comment 🙂

@@ankitsayzz did you solve it? im having the same problem

@@naimulhasan3631 bro where do u have updated in comments can u do it here please

Check the stackoverflow link I have added above.

sometime i may have done more but usually it is to add the padding margin and decoration if required

i fix it with import 'package:cloud_firestore/cloud_firestore.dart'; 🤦‍♀️🤦‍♀️😂

it happens how much have you completed yet?

No it will not. you can do that

Could you please share the Github Link, I can help you.

@@soumyasouravpatnaik2246 Hey can you please help me , I am stuck at 01:06:22 I am tried and replicated every code until then, but on typing the name, I am not able to find user.

@@devhalder7799 hi, i am having the same issue here as well! did you manage to fix it?

Similarly how we did for username just need to change the field the key name does this makes sense?

You're welcome! Shubhaankar what tutorial would you like to see next?

@@indianappguy it would be really awesome if you could create tutorial for creating a social media clone with using http calls instead of firebase (REST API)

@@shubhaankarsharma noted will do

You're welcome!

the () will actually execute the function, and that's not what we want, we just want to pass the function as a parameter. So when we pass it without the (), the memory address of the function is passed as argument and that's the use case for SignIn and SignUp. Hope i helped u

Muhammed Adil Oh thanks, actually i figured it out sometime after this question was asked, but wasnt 100% sure of it. Thanks for the answer, im more confident now

what?

And i have the same problem, i don't know what to do

yes

Please use flutter clean ( Tools -> Flutter -> Flutter clean)

Network problem...restart your internet

still facing the problem?

@@indianappguy no it's working now.. thanks for reply

How you solved please help me .

and this is not proper way to make a search. If u don't put exact value u will have error. Because snapshot will return null

i have a problem too ! you resolve this error ?

Same problem did u solved?

replace AuthResult with UserCredential

@@bereketzerihun2287 replace AuthResult with UserCredential and FirebaseUser with User key word package was updates

i just fixed it! all you have to do is install the firebase_core in pubspec.yaml, import it to the main.dart file

void main() async { WidgetsFlutterBinding.ensureInitialized(); await Firebase.initializeApp(); runApp(Main()); }.........replace the void with this in the main.dart file

Maybe you should import the firebase core too

I fixed it.You need to add some line of code in setting.gradle. You can find the code in google if you copy paste your error.

it's just preference or can say habit you can use that as well

@@indianappguy ok, thank you for the video ❤😍

@@mouhamedbarahimi1441 you are welcome please do share if you find it valuable it really helps

delete firestore and authentication data and try signup again..

Please re-check your email ID that is being passed from the TextFormField

Use .trim() in email

Did u solved this error?

@@nithinkundapura7660 just answered at top
