for all those people asking how to display current users data only . just chnage two things. remove this ( final user= FirebaseAuth.instance.currentUser!;) instead write this(User? user = FirebaseAuth.instance.currentUser;). after that inside ur function change ur collection and write this ( await FirebaseFirestore.instance.collection('listof').where('email', isEqualTo: user?.email).get().then( (snapshot) => snapshot.docs.forEach((document) { print(document.reference); docids.add(document.reference.id); }), ); ) . after this u will get one error. right click oh the error and change and it will give u an option to add null.. add that and this willget current user data on the basis of email.

Hey man, great videos! I have a situation: Instead of naming the collection 'users' I'm using the name 'owners', and now I'm getting duplicated docIds with the getDocId Future, even though my Firebase DB does not reflect duplicate data. Any idea of what couldbe causing this behavior? Thanks!

Yeah I have the same trouble every time I hot reload it adds to the global list. Because every time it adds the data from fire base on top of what has been added to the list. How can I get the data without saving it to a list?

can you do a display about spesific information from currently logged in user?, not just everyone name and ages

For that you will need to use the .where(). The code below worked for me User? currentUser = FirebaseAuth.instance.currentUser; await FirebaseFirestore.instance.collection('users').where('email', isEqualTo: currentUser?.email).get()...

Nice videos Mitch! Keep up the good work 💪🏼 I've followed along and for some reason, the data is still being duplicated. I've looked into the docs for .removeWhere and I can't seem to remove the duplicates without deleting all the entries. Do you have some advice on this?

[@createdbykoko]

Hi Simon, I’ve noticed when we hot reload it duplicates the data because it preserves the app’s state but still re runs the getDocid() method. If you full restart (shift+R) to rebuild the app, it works normally as we want. Does this help you at all? If not let me know, i’m happy to sort this out for u

Create stuff, just subscribed. But I believe you should avoid using forEach in this instance, especially if you want people to understand better. A beginner out there is scratching their head becauses of the forEach loop.

[@saratiko]

Good video and I understand what you want to do, just want to inform you that you make a lot of unnecessary calls to the server with this code. With lots of users using the app every user will make tons of requests getting the names, especially if you add more functions in the same manner and not to mention more users can easily become costly using firebase where all request will turn into payment needed by firebase, with some optimisation to the doc getting and storing it in the initial request instead of first getting ids and then making one request for each name will reduce the amount of requests greatly.

[@createdbykoko]

Hi Jim! You raise some great points and I completely agree with all of them. But because many beginners watch my tutorials, sometimes making the code a little less optimised can help newer beginners to grasp the idea first in a simple manner, and then now they can think about optimisations and making minimal requests as the app becomes more complex. Otherwise, they won't even know what optimisation looks like and the importance of it. An analogy I have for this is when you are learning arithmetic in maths, you first need to understand what 3+3+3+3 means, before you jump to 3x4. Obviously a more proficient math person will look at 3+3+3+3 and think, dude you just need to do 3x4, but my goal is to teach people HOW TO fish, instead of just giving them the fish.. if that makes sense haha. But still everything you said is correct and you seem to be much more pro than a beginner so that's great!

[@saratiko]

@@createdbykoko i understand, good explanation here too. I like your videos and you’re a good “teacher”, easy to listen to and easy going, not doing things hastily. I don’t know if I would call myself a pro, loads of things I struggle with as most developers do I believe, but thanks for the compliment, just wanted to give my “cents” in case it was unintentionally, perhaps you’ll go deeper in other courses that’s not beginner class and more for intermediate to advanced class?
