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!

CRUD stands for Create, Read, Update and Delete respectfully

[@alimehralizada]

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?

[@nhexplorers]

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?

[@HeyFlutter]

Thanks for the idea, Nacho Libre! 🙂 I have added it to my list of ideas for future videos!

[@helvecioguimaraes]

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.

[@HeyFlutter]

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
