I was skeptical at first seeing just how short the video is but you proved me wrong, this is a really great vid. Simple, short, to the point, no stutter on your voice, very professional. Thanks a lot.
Glad to hear that, Thank you Jun! 😊
I cannot explain just how helpful this video was to me. Thank you so much
You’re most welcome, Prize! 🙂
I have watched all these request videos that you uploaded in chunks or individual, still i watched the video for making it clear i didn't miss any thing..
Old Subscriber❤👍
I am glad to have found our channel. Very good explanation and code of everything.
Thanks.
Glad to hear that, Thank you Thomas Schroeder! 😊
this is the best channel for flutter I have ever met🥰😍
Thank you so much for your tutorials. Irreplaceable!!
The best tutorial I've ever found! Huge respect! Hello from Kharkiv, Ukraine!
Glad it helped, Dmytro Skurikhin! 🙂
Hope everything is good bro!
Really good video, shot and informative. Hi, from Mykolayiv, Ukraine
Wow, very very good content here ! I'm trying firebase for the first time so i'm still confused on the relation between data (how to only target the documents of a specific user for exemple). But this was not the point of this video ! For the basic implementation of the CRUD with flutter and firebase, this is exactly was I was looking for !! Great Job ! Many thanks
Glad to hear that, Thank you Victor Mth! 😊
Your content give me more idea and ability to create a great app. Thankfully.
Great tutorial! I have a video idea for you: Flutter how to center Textfield on screen after the user taps on it? When we usually tap a TextField, it will be positioned a little above the keyboard but we do not want that if we want a better UX
Now I'm a huge fan of yours, you're a Flutter avenger, literally!
Glad to hear that, Thank you I Flutter You! 😊
Thanks for the to the point video. I was able to execute the project without exception with your help.
Glad I could be of help, Thank you ruchir santuka! 😊
You're the best at this sir 👍💯
thank you very much, i'm not good at english, but you're video is very helpful by using clear and easy english also good to comprehend. thank you!
Thanks, for your support, Sheer Dev! 🙂
Great tutorial. When was this video created? Because when setting up you Flutter project on the Firebase console, I believe you no longer need to select Android, but can select Flutter, which will be right next to the Unity logo. It's easier that way.
Great video ever about Firebase. Really!
Sir thank u i had gotten from U a lot things
thank your video so much! it helps me, hope you create more video about Flutter 🥰
Glad you liked, @touyenaothi7548 😀

You are welcome, amjad zayed!
very helpful to me, thanx dear
Thanks, also Manish Mor! 🙂
I run into the issue of getting error: Expected a type String but got one of type Null.
Solved it by:
- Add inside the model Users null safety so:
final String name becomes > final String? name
- And inside the listtile your Text with the value inside needs to change from: name to: name ?? ""
Hope this helps out someone who also runs into this. Also a good practice to always add these checks.
Thanks Johannes for another great tutorial!
Great, Thank you Tom!
Excelente video! Me sirvió.
Thank you, Mattias Peralta! 🙂

So amazing!

Hi, Mike, at the first thank you for all, you are amazing! :)
I have an error with StreamBuilder, everything is working when it has an internet connection, but when i disable it for testing, everything in StreamBuilder is disapearing after 3 seconds. Can i use nested StreamBuilder (1 - to check internet connection(with connectivity_plus package), 2 - if it has stream data from firebase) or it has better way?
P.S. i checked each way to return the data (if snapshot.hasError, snapshot.hasData, even !snapshot.hasData, else and after else..), but something went wrong after about 3 seconds if internet connection is off.
P.P.S. In short, can you check your program without internet connection?
this video is the best guide for firebase
Glad you liked it, @user-lf6db1zf2c 😀
would you make an updated version of this since firebase officially supports flutter now? im just curious
Thanks alot
Search data from local database in implement staggered grid view
awesome tutorial
Thank you, Hugo Gomes! 🙂
Thank you for the great tutorials. Request: Can you make a tutorial showing how to manage Firestore CRUD operations when the user loses access to a data connection. For example, if the user submits an update to Firestore with an async function but there is no data connection - how do you skip the await process and yet still update firestore later when there is a data connection?
Thanks for the idea, Nacho Libre! 🙂 I have added it to my list of ideas for future videos!
What is the benefit of using a model object?
Next, make a video about firebase remote config. Make a video on how to save the API key in the remote config, and how to change the behavior of the app using remote config. For example how to send a pop-up message to update an app using firebase remote config 🔥
Hey man, great Video, helped me a lot!
I have one more question maybe for the other people as well:
How can i check if a document inside my firebase database with a given id is already inside my collection? Would help me a lot and im struggling at the moment!
Thx alot and have a nice day!

Sir, please make a video on firebase cloud function for firebase database crud operation in production mode for authenticated users.
It's not a Firebase database tutorial, but a tutorial for Firebase Firestore! Those are different products!!
Nice❤ Thank
You are welcome, GAME VLOGS!
Sir please Create CRUD operation in AWS .please Make an Video about this topic.
Please help me. I tried using your method in the "read data" part of the video in displaying images from firebase. I have some trouble in precaching the image with the user.map(buildUsers).toList() inside the ListView under the StreamBuilder. How do I precache the image?
Thank You raves_r! Follow this link: medium.flutterdevs.com/precache-images-in-flutter-73abfedb0769
I hope you will get your answer 🙂
Hey, this is an awesome tutorial, thanks! Now, I see most of people talk about Firestore, so I wonder: is there any value in the Realtime Database? From what I read in the official docs, it is mostly suitable for nimbler, smaller projects. Apart from that, is there any reason why I should use it instead of the Firestore? Cheers.
Hey, Helvecio Borges 🙂 Realtime and firestore both fulfills differnt requirement, firestore can be used to handle large data while realtime as name says can be used to handle realtime operations
@@HeyFlutter awesome, man, many thanks 👍
I see title "CRUD" alot on RUclips then I don't know what's mean , Thanks you for nap a litle meaning on this clip title .
CRUD stands for Create, Read, Update and Delete respectfully
Thank you my brother

When I try to run the main.dart file after setting up the Firebase with Flutter, the error below occurs:

9:46 your red squikly line disappeared when you made that buildUser method.
my code still shows the error.
error:
The method 'map' can't be unconditionally invoked because the receiver can be 'null'. (Documentation)
even if i Alt+Enter on the error, another error appears saying as below:
error:

I cant see any videos on your channel that discusses DELETION specifically removing a document and all collections/subcollections - It would be great to see your approach on this ...

Hey Johannes, may i ask how do we get data from a single document with an autogenerated id instead of the personal create ID.
final userDoc = FirebaseFirestore.instance.collection("users").doc("my-id");
i want to place an auto generated ID inside .doc() call

@@HeyFlutter I still dont get it.
No it didnt help really.
I still dont get where the id variable is comming from.
StreamBuilder(
stream: FirebaseFirestore.instance
.collection('YOUR COLLECTION NAME')
.doc(id) ////////////ID OF DOCUMENT////////////
.snapshots(),
builder: (context, snapshot) {
if (!snapshot.hasData) {
return new CircularProgressIndicator();
}
var document = snapshot.data;
return new Text(document["name"]);
}
);
}
infact I created a form with the stepper widget that I manage to register on firebase firestore. a form (name, address, pincode...).
I would like to display a message to the user in case he enters a name that already exists in the database.
Hey, Oumar Zabre 🙂 you can first read/load user's info from database and then compare whatever values you want to

i saw that stack overflow post you linked on your other video but i don't understand how it fixes the problem
@@HeyFlutter hmm I followed all the steps, everything seems the same. not sure why .map isn't defined for snapshot.data
@@warrenstrife4818 make sure that your StreamBuilder has its type specified as such StreamBuilder. Let me know if that worked :)
