Easiest way to understand BLOC Pattern in Flutter 

14:27 decreasing by one lol but still very good explanation. Thank you for your time in sharing your knowledge.

All the other "Easy" tutorials assume some intermediate level of understanding. this truly is the "EASIEST" bloc tutorial on the internet. thank you so much!

Excellent explanation of the fundamentals of the BLoC concept and a great example of how to implement the code! Thank you!!

9:45 Thanks for that difference between yield and return. Put very simply.

You helped me to learn both Provider and BLOC. I really appreciate your work. A lot of thanks to you :)

Great video with fantastic way to explain complex things! Thanks for sharing your practical knowledge in this bloc tutorial.

Thank you, gentleman. It Helped. Relief of working with flutter from one and a half years and finally understanding how bloc works.

Thanks Bro! I just got "aha!!" on BLoC after watching this video. Keep up the great work!

Woah, I finally understood BLoC after nearly giving up on it! Thank you so much for this. It all makes sense now!🎉

Muchas gracias mi hermano, buenísima explicación. Thanks for keep it so simple and understandable

Great! thank you for simplifying Block...much appreciated

Great stuff.. Thank You for explaining it very well :)

Thanks for your explanation! Just one thing, I read the documentation before, I think that importing flutter_bloc is enough, it will import bloc by itself, no need to re-import in the project!

Thanks for this Awesome Video brother. Now i understand bloc clearly.

awesome! simple way of implementing! thank you

Just change in counter_bloc -> yield state-1 (when event is decrement) and u are good to go Nice video

Easy approach really has easy approaches

Really thanks to you for great explanation of bloc

Very concise and helpful! thank you

This is a very good explanation. I would like to hear some differences with the Provider package and other Simple alternatives as well. Like BlocProvider is the alternative of Provider, BlocProvider.of(context) is an alternative of Provider.of(context) and BlocBuilder is alternative of StreamBuilder, etc. But very good video man really forced me to subscribe as well.

19, 20, 21... "as you can see, it is decrementing by 1"

Very clear and concise. Keep it up!

After watching this, I wished that I could subscribe you n number of times. Great work

thanks helps a lot keep doing this you are a very good teacher

this is excellent, cheers mate from australia

EXCELLENT TUTORIAL !!!

Thank you. Its really helped.

Nice explanation, thanks !

Excellent thanks brother . Keep it up.

This is the easiest video...Thank you

Best explanation..Thank you so much

I like how the inc/dec events are just enums, not another class! In CounterBloc you initialize a "initialState" variable to 0, but in the inc/dec event you update a "state" variable. Should these names have been the same? Is the counterScreen UI widget a child of counterBloc? In the CounterBloc's mapEventToState, would it have worked if you would have used "return" instead of "yield"? Or, in general must 'async' and 'yield' always go together?

Saved me. and my day ! thank you man.

Your accent I think is an effort to me well understood. Good English. In the switch there's an typo. In option to decrement you are adding (+) instead of (-).

Very good! A tip for you for future videos: 1. Always prepare a script of your screencast. 2. Record full video without speaking, just focus on your coding. 3. Voice-over and annotate your video

Great job! Thanks.

Very nicely explained. I was confused AF until now

Thanks man. Nice explanation

Good Job. Thank you bro !

bro, you thank you so much!

Well done, Mazz :)

actually a good explanation

Sorry to ask but how did you understand BLOC pattern when you were a beginner? Any resources, books that you recommend.Your video has helped a lot but still I want to go deep and learn more

bro good work!!!

very good and simple explanation. thanks sir

Too many advertisements, However, you explained very well.

can you describe yield state + 1; how can judge state variable as you are using butt not declare any where in file.

great job. Thanks for your efforts. subscribed. Accent u know :)

kindly please update the bloc tutorial video ,I'm getting errors like this below "BlocProvider.of() called with a context that doesn't contain a cubit of type CounterBloc"

thank you very much

Amazing! You are awsm!

Was it really decrementing though?

Nice Video For Beginner Tanx

good stuff..

Subscribed.

Thanks for sharing

Bro, how should we handle dispose in flutter_bloc ?

also why we used patterns anyone like provider or bloc etc etc what the actually need of this paradigm in development

On clicking decrement it is showing incremented value , I think you by mistakenly given yield state + 1 in decrement case instead of yield state - 1 . Am i right sir ?

Very good video. just one thought as viewer, your english is very fluent, just sometimes it tough to get when you speed it up, hope you make it more sound natural.

Whats the difference between BLOC and MVC ? Looks same to me.

Ok so, I tried here and it works, but now, flutter_bloc is 2.1.1, and Android studio is telling me that: 'builder' is deprecated and shouldn't be used. Still working, but is telling me this...

Please give example where I can use multiple bloc

you explained very nicely but i am facing a little confusion why we need to used bloc pattern instead of simple variable logic

how about with counsume with A Api

At this time (May 2020) the BlocPrivider doesn't have the build: ... Instead, it has create:

can i request video Flutter_bloc with Listview Builder that receive data from API? Thank you

thanks bro ,but for this update you should use class CounterBloc extends Bloc { CounterBloc(int initialState) : super(initialState) { on((event, emit) { switch (event) { case counterEvent.increment: emit(state + 1); break; case counterEvent.decrement: emit(state - 1); break; } }); } } instead of class CounterBloc extends Bloc { CounterBloc(int initialState) : super(initialState); Stream mapEventToState(counterEvent event) async* { switch (event) { case counterEvent.increment: yield state + 1; break; case counterEvent.decrement: yield state - 1; break; } } }

You've missed the Repository layer which supposed to be in between Data and Bloc layer

What if you had 100 different states to keep track of globally?

why we need bloc pattern sir if we can do the same work easily

Which is best, Bloc pattern or Provider ?

I have no problem with your accent. I don't why some people has.

Gracias

github link is not working

It's hilarious that you didn't even notice that decrementing is not working as it should. Great explanation though!

I think this is the easiest bloc video that I have ever seen...

Nice an explained tutorial,,, thank you... But it's not decrementing the value...

Very cumbersome pattern for simple apps, a lot of work for basic things. But should see in really big apps. Not sure about the performance however.

What is the benefits of adding this??

Nice video.. He made typo on 10:04.. Rest is very informative.

Wrong: Stream is to send data out for consumption and Sink is the point where data is added by the bloc so that it can be directed to stream.

CounterBloc.dart //int get initialState =>0 CounterBloc() : super(0) main.dart body:BlocProvider( //builder:......... create :........... )

I think you are not right telling that async runs in a different thread because all Dart async programming is still synchronous and goes on the same thread. To use different thread you need to create new isolate using features of dart or use compute function which does everything for you. Read some articles about event loop and microTask loop.

Hey please make a full video on login and signup using the http get and post request.

you didnt show data being passed from the data provider to the bloc............

Async does not create another thread. Dart is a single thread language.

Reso coder?

both event yield + 1 as the int state XD

I think you got the wrong understanding of decreasing the counter :P. BTW great work.

if this is easy approach than what is complex......... your initial explanation was is good making things simple but creating ur porper base is necessary... i think more accurate approach in initial explanation was necessary , every aspects needs to tracked

I determined to not watch after repeatedly hearing bloc pattren instead of bloc pattern.

"State is the data you application is currently showing". Nope. It is ALL the parameters that defines what it should show. It is NOT the data. Data is the last in the queue.

Good job bro. Just a kind request, please leave your fake accent. Be real!

not working

bloc pattren

So.. this seems like a presenter pattern to me...

You make your video very nice but your talking speed is very high so keep your speed little bit slow.. thank you

ads bhot h

This dude creates good content but trust me his fake accent kills...
