Flutter: Firebase CRUD Using Cloud Firestore | BLoC Refactoring

[@RobertBrunhage]

Have had many requests on making a video without BLoC and one with so here is some refactoring on how to make last weeks CRUD Firestore video into a BLoC CRUD with Firestore! Hope you enjoy :)

[@leonardoventocilla3275]

YES !!!!! I´ve being waiting for this for a long time. I stoped all my projects/studies to focus on this. Thanks for the tutorial ..

[@em3888]

Great, Can we do BLoC + Firestore + Google Login + Email Login? I am looking for a best practice for a while

[@RobertBrunhage]

@@leonardoventocilla3275 Haha awesome, happy I could help and thanks for the support! :)

[@RobertBrunhage]

@@em3888 Something I am looking to do in the future, it's quite a long/complicated video to make but will do my best :)

Thanx for teaching us how to copy Paste

[@yanischetouani7392]

whay you did not use Bloc event and bloc state ?

[@ptflag]

which previous video are you refering to?

[@LexPrimost]

Hi i want to use multiple bloc for differents page. How do that with your method ? Since the bloc_provider in the main.dart only takes one bloc as a child what is the proper way to do that. I am aware of flutter_bloc package wich have an option to group blocs but your way of creating blocs is much more understandable and clear. Let me know. thanks again

[@RobertBrunhage]

There are two main ways. The first one is just that if you want another top widget BLoC just wrap another BlocProvider. The other one is to have a "AppBloc" which the other bloc is created in with getters. I have a post on my patreon explaining the latter one and linking to a medium post from David Anaya: www.patreon.com/posts/26189310 The post should be public :)

@@RobertBrunhage thank you i appreciate !

[@LawZist]

great video! do you think BLOC is the way to go then redux for flutter ?

[@RobertBrunhage]

I still believe in the vague answer of it depends. I personally like using BLoC as it gets pretty straight forward when you get through the basic concepts i.e the points I made in the BLoC tutorial series on. But I believe Redux is a great way especially if you are doing web development also.

Great content!!

[@RobertBrunhage]

Thanks, happy it helped! :)

[@bremington2010]

I am not clear on how many streams to create for an application. My app is using a single database from SQFLITE and also storing some values in shared preferences. SQFLITE has 5 tables. Do I create a single stream for SQFLITE and one for Shared preferences? Do I create a stream per Table? Thank you!!

[@RobertBrunhage]

That all depends on how you want to handle your data. For example I have 4 tables in my app which all has something to do about the user. It may be a User table that has a connection to a table of friends. Now what I would do is take the data from the table, put that in a class or multiple then stream out the data the way I want it. So it may be 1 Stream for all the data as it is in one class or it may be 5 streams as all the data is independent. Hope that makes sense :)

[@KhainiSader]

Can you monitor your firestore usage? On opening an app(starting it up), does your firestore redownload the documents that are being displayed?

[@RobertBrunhage]

You can monitor your usage of Firestore in the console by going to Database and then usage :) A bit unsure about the redownloading so maybe a question for the Firebase support.

[@KhainiSader]

​@@RobertBrunhage Can you look at your firestore usage in the console? Is it charging reads, lets say the data has not changed and you open the app after 30 minutes(app is closed for more than 30 minutes)? Thank you!

How did you wrap your widget with streamBuilder via context menu? I didn't find with with default dart code extension

[@lovefrommemee5710]

Alt+Enter or if in vscode right-click on a widget n press "Refactor".

[@RobertBrunhage]

Didn't actually notice when I got this. Can be because I am sitting in the dev branch, maybe? Before I had this I used "Awesome Flutter Snippets" for visual studio code, to get the short command stb to build a StreamBuilder!

[@RobertBrunhage]

@@lovefrommemee5710 Can also ctrl + "." in VS code 🔥

[@Kodeversitas]

OK got it, it just my extension is outdated

[@nicolapigozzo5188]

Is possible for you to make video about checking memory usage? I like the tools we have on android studio

[@LexPrimost]

Hi thank you for this one too. Can you lead me to the tutorial about bloc provider which you mentioned before using the bloc provider file?

[@RobertBrunhage]

Here is the part where I implement the BlocProvider kzbin.info/www/bejne/h5-koHiMarqll6s Here is the code from it which you can just copy and paste: github.com/RobertBrunhage/KZbin-Tutorials/blob/master/bloc_pattern_tutorial/lib/widgets/bloc_provider.dart

[@LexPrimost]

@@RobertBrunhage thank you appreciate that

[@RobertBrunhage]

@@LexPrimost Happy to help! :)

[@argigentarna]

Really nice tutorial, i hope you create other study case with bloc, like whatsapp clone, uber clone, or the others..

[@RobertBrunhage]

Thinking of doing something like this is the future but still unsure, We will have to see :)

could you do a video with php and mysql/SqlServer implementation ?

[@RobertBrunhage]

Something I would love to do, sadly I haven't had time to learn this myself so this one will take a while... :/

[@Trancecend]

A million tutorials out there about that. Php is old, so lots of resources exist.

[@nmgbjh]

it not real time ????

[@RobertBrunhage]

What do you mean?

[@nmgbjh]

@@RobertBrunhage I want to get realtime data ,but When I use this method, it doesn't work !! plz helps me

[@RobertBrunhage]

@@nmgbjh Hmm that is weird. The whole point of this is to listen to a collection to get realtime updates. With the init function we say that the data from Firestore should flow to our bloc and that will then be added to our stream which is displayed in the UI :/

[@nmgbjh]

@@RobertBrunhage yes ! I have tried every way I can @@ but it does not work @@ it does not listen to the data

[@RobertBrunhage]

@@nmgbjh And you can see it updates in the Firestore Console?
