Codelab: Get to know Firebase for Flutter

[@tomicriedel5005]

Finally a complete video for Firebase! Exactly what I need now, because I'm sitting on a problem for 10 days, thank you 🙏🙏🙏!

[@MysticZA]

Loved the way you added your Firebase experience to the security rules section of the video. Having watched your Firebase videos I knew it was going to be a good one.

[@sonxuannguyen1207]

I had always longed for an interactive live coding tutorial like this ❤️

[@imransefat8770]

Firebase In App Messaging, Cloud Messaging tutorial would be a great addition this video!

[@ryansampson7221]

10-hour code lab yes please

[@moverecursus1337]

Would be awesome a new version of this, as is outdated today

[@delarammajestic2502]

please provide a 10 hour long code lab ...i would be happier if you do a full detailed course about 30 hours on how to handle the different needs in our applicaiton with firestore .....Im in love in flutter and Im ready to peactice and learn

[@joestunes]

Thank you Todd and Firebase Team, this was very helpful.👍

updateProfile is deprecated in this line : await credential.user!.updateProfile(displayName: displayName); replace it with one : await credential.user!.updateDisplayName(displayName);

Good lesson 👍

Thanks! 😃

진심으로 고맙습니다. 덕분에 잘 학습하였습니다. ^^

[@oswaldoolea2889]

very good, great, everything works, thanks

[@barisbasar3909]

I think someone changed the codebase...

[@wandasingela]

I think so too, my Register and Sign In screens don't look right.

[@faheemahmad3957]

please remake this for 2023

[@riobijanero1]

thanks for this Great video. I'm wondering how to write unit tests for this project. do you know about resources I can use?

[@Firebase]

Hello! Please check the following guide for more information regarding unit testing: goo.gle/3PAnskN

[@collinsmutugi1388]

Adding a class that does all the crud operations for cloud Firestore and an authentication class that takes care of the authentication state for firebase auth removes a lot of boilerplate code. This means you can leverage the provider plugin better.

[@_joejoe_7863]

reminder for me: thanks to @JohnnyFanta In the main.dart I changed this line that was from the codelabs code 24:25 Future init() async { await Firebase.initializeApp( options: DefaultFirebaseOptions.currentPlatform, ); And changed it to the same code on the video await Firebase.initializeApp(); And now I can login and logout!

[@Firebase]

We're happy you were able to get things sorted out! Thanks for hanging in there 😊

[@vinayreddypulagam]

Is there is a way to upload/download images through flutter web without importing dart:html??

[@jakewoodruff13]

surprised nobody has commented this error. When editing main I am getting: The argument type 'dynamic' can't be assigned to the parameter type 'Widget'.

[@learnwitharslan1049]

same i am getting this error today. did you fix it. do you have any solution. help me. looks like i am dying 😭

[@Tabvn]

is there official document for firestore database structure and also support group chat, members, app notification when new message from. :) need an official data modeler

[@jsebastian211]

Is very useful that kind of video, i only have one question, is normal or common define de methods auth's logic inside of the ApplicationState i'm not expert in flutter but is not normal put into the authentication file instead get it across parameters or put ApplicationState inside another file or inside in authentication 'folder', can it listen from multiple changeNotifier or only once ? thanks!!!

[@risongna2537]

In the "Reading documents from Firestore in real-time" section, any reason why you did not use StreamBuilder?

[@risongna2537]

@@ToddKerpelmanCorp Wow, that's a really quick response! I'm trying to figure out pros and cons between providers and stream/future builder. But I guess that's a flutter question. Thank you Todd!

[@davidagyakwa288]

I index a nested collection for searching purposes ...but when I tried to to use flutter to search all docs in the collection it didn't work .....can you do a video helping with this

[@manishkl1]

you need to update both the codelab firebase get to know on web as well as this codelab.... thanks

[@nalindawickramarathna8730]

Thank you for the great content. Can you create a demo for paginated data for Firestore in Flutter / Dart? I have over 50,000 records per category and around 100 categories. Or someone can direct me to an already available learning resource to do this.

[@JohnnyFantaOrange]

Can anyone confirm if this is still valid, I tried a couple of installations and 24:45 Enabling User sign in pressing next no action is getting performed showing same screen.

[@ayoubmentag9883]

I got a blank page while trying to run the step 02 , anyone has a solution of this problem ?

[@KludgeMaker]

Win10, VSCode, no iOS devices listed, (Android phone plugged in), but when I try to run the code at the beginning of step 2, no matter what device I select, I get "No supported devices found with name or id matching 'iPhone'." Ideas, anyone? Thanks in advance.

Although there is compileSdkVersion flutter.compileSdkVersion in android\app\build.gradle , however I get error : " Could not get unknown property 'compileSdkVersion' for extension 'flutter' of type FlutterExtension." , could you please help

great

[@whitemagehealing8126]

Wait, what? Are my messages sent in the clear even though I sign in?! The admin can read everything I send. O_0?! The advertisement of Firebase was that I could sleep at night and not worry about security, why is so much implementation manual and, thus, easily breakable? Is this a flutter limitation, a client platform limitation, etc.?

How can we set up the iOS app with flutter on Linux (Ubuntu)? Can't use X code.

[@CrashOrFly]

No, you can't. You need a system running iOS to use X code.

[@helloworld101]

@@CrashOrFly so I need to buy at least a MacBook or something to build the iOS app. I don't have any apple device lol... Would be new for me.

[@CrashOrFly]

@@helloworld101 No, you can build the iOS app on Linux or Windows but, in order to test it, you need a phone running iOS or a simulator (as Apple calls their emulator). Simulators only run on iOS machines like MacBook.

This is a note I made to myself. you can probably disregard the macos line if you are only building for mobile make changes to ios/macos files or you’ll get a CocoaPods error on run/debug macOS/xcshareddata/project.pbxproj ~line: 473 MACOSX_DEPLOYMENT_TARGET = 10.12; ios/Podfile ~line:2 uncomment and change to: platform :ios, '10.0'
