#4 - BLoC Architecture - Presentation, Business Logic & Data Layer + Model, Repository, DataProvider
HTML-код
- Опубликовано: 18 сен 2020
- Hi there!
Today I'll try to explain you why the BLoC Architecture is the key to building a strong and stable app. So, we'll dive into the Presentation Layer, Business Logic Layer and Data Layer (which includes other small sublayers like Models, Repositories and DataProviders (APIs)).

I see high-quality RUclipsr here 😍
Thank you so much!
I vouche for that! Please keep making videos! @Flutterly
It's just amazing how much effort you put into these videos - Impressive.
Thank you so much! I appreciate it!
How can someone explain such complex concepts with such ease and clarity 🔥🔥🔥
Thanks to your tutorials I've corrected lots of my mistakes and made my project more efficient. Thanks for the tutorials, keep it up!
I'm really glad to hear that, thanks!
Bro, I fell in love with your content
Thank you so much!
I was literally waiting for your next video in the series...good work!
Thank you, more to come!
Whenever I am learning new technology, I'm struggling to find tutorials like these. Great tutorials.
This is GOLD! Every single tutorial has been very brilliantly dealt with so far! Thank you!
This is the best bloc tutorial ever..I'm so grateful
Thank you so much! I've finally learned these difficult concepts after many months of reading and watching videos over the entire internet with no results. And you in 15 minutes explained, in an understandable way, what others couldn't do in hours! From now on, you are my idol! 👍
no way! even the creator of bloc flex didn't explain it the way u did
KEEP GOING U R AWESOME
Thank you so much! Actually, Felix, the creator of BLoC is one of the best and most helpful people I have ever had a chance to talk too! He helped me a lot with these videos and overall with all the concepts back then when I firstly encountered bloc and Flutter. ♥ Thank you for your feedback though! I appreciate it!
After watching the ResoCoder TDD with Flutter BLoC series, I thought nobody would be able to match that quality of content. I have to admit that I was wrong. The quality of content in your entire BLoC series is amazing! 🔥
Thank you so much for your kind words! I appreciate it! ResoCoder has put more accent on TDD rather than BLoC on that series, but it's still an amazing series nonetheless!
This is the first group of tutorials that I have watched that actually makes sense. Thanks for this, I might finally be able to code properly now.
you are best teacher of Flutter that i have ever see...keep it up...
Awesome, I think no one has explained it the way Mr. WCKD has. Simple, intuitive, and complete.
Thank you so much! ✨
I guess No one has ever explained such things in such simple manner. Thank You for taking out your time and creating such videos.
You are most welcome!
i just cant thank you enough.
you have made it so clear and concise for a beginner like me !!
lots of love and respect for you & your hard work !!
Thanks a lot !!
Loved the architecture comparison between the human body and code. Can't humanize tech more than that. Great work!
Thank you so much!
the best bloc course ever in the internet thanks a lot
Great video as always! Loving this series! It's like a introduction to the DDD of ResoCoder but teaches more easily somethings that aren't said there. Really glad that the next video will be about bloc testing!
I'm glad I could help. ResoCoder's TDD series is also amazing and well structured! Lots of things to be learned from that too!
@@Flutterly man, I don't know if you know that but Feliz (creator of bloc) posted this video on the bloc discord channel. Congratulations! I think your videos will be very helpful to the community!
Thank you so much! Didn't know, but I know Felix is an amazing and helpful person! 🌟
Excellent videos dude, I keep coming back to certain frames of the video to get that one overview, just to refresh my memory. Keep up the good work!
Thank you so much! I appreciate it!
You are a king man, thank you so much for this BloC series
I immediately subscribed without hesitation. I've learned a lot in just 15 minutes, man you are great!
Thank you for your feedback! ✨ I am glad you like my content!
The most simple and comperhensive tutorial about BLoC. Thanks Man! I appreciate your work
Thank you so much
This channel is gonna blow up for sure!
Haha, hopefully it will, man, I really appreciate it!
If youtube alows me: HOLY DDDDAANNNG FKKK!!! THIS IS GOLD! I understood more in this video than in LITTERALLY 3 hours of my flutter teacher on Udemy.
I am literally unlearning what l thought I learnt properly through other content creators. Thank you, and keep it up! I am binge-studying and making changes to my apps
Thank you so much! ✨
I have no idea of Flutter, was only looking for videos that describe business logic. You put so much work into it and explained it very well!
Thank you so much, I appreciate it!
Your content has helped me a ton! Thank you for the time and effort that you put into these. Keep up the good work, I’m sure more viewers will come!!
Thank you so much for your kind words! I appreciate it! I'll keep the content coming!
Finally clear up my doubts on where to implement try - catch.
So i should now wrap all my blocs functions in try- catch now
Yes, it's a great solution to take care of problems caused by the data layer. You should also wrap the repositories and data providers too
Flutterly you mean I have to wrap try - catch for ALL layers?
Yeah, I meant you should wrap any operation that you know may cause issues into a try/catch
Perfectly explained man! Way to go!
i swear my god i am so happy to find your videos you r the best mannn !
Fantastic!! This is by far the best tutorial I have seen on bloc and application architecture. Amazing. Thanks a lot 😃😃🙏
Thank you so much, I appreciate your feedback!
A clear explanation, indeed. Bravo!

Yesterday i searched google "understanding flutter bloc for beginners" and this video came out and today i am watching from the beginning because it gives me what I was looking for as a newbie in flutter bloc. Amazing explaination, a newbie like me understand it very well lol. Keep it up please. Btw i also want to understand flutter clean architecture in laymans terms or how you are explaining it here. Thanks, done subscribing. 👍🏻
Thanks a lot, these videos are beneficial, I don't know how do I thank you

Thank you. The best tutorial I saw about how it works Bloc.
Thanks a lot! ✨
Very very nice. Thank yo so much.
Question: at 8:19, you have calls to 2 different APIs (one of them is commented out). How can you safely do something like ‘Weather.fromJson(rawWeather)’ considering that (as you mentioned earlier) the JSON responses might be completely different from one API to the next?
I feel like I missing something here @Flutterly?
Also, thank you for making awesome series. It is really quality content!
Hi, Thanks to your tutorials and It's amazing.
I've corrected lots of my mistakes and made my project more efficient.
one suggestion bro.. pls make real time code in video.
Thank you soo much! Amazing explanations !!!
Thank you, brother 🤍
Simply amazing video, could not wait for the real coding part 👍🏻
Thank you so much!
I only there could have only intermediate-advanced Dart-Flutter tutos like these on the internet and not basic ones that are so easy to find 👍
Thank you! I can understand easier.
Great explanation with clear illustrations, I can say I didn't see something like this before. Keep doing the great job, and please make real, really real application apps, even if it is paid I am the first subscriber.
Thank you so much, I will! They'll be free, I want everyone to have access to my content! ✨
WOW !!! amazing and high quality content !! Thanks
Thank you so much!
Great video! Like you said, need to watch it at least 2 or 3 times. :) Thanks!
You're welcome! Glad it helped
Thank you very much, I understood all the concepts, your explanation is beautiful and understandable ، I wish u all the best 💙
Thank you for the positive feedback! Seeing that everyone understands and learns something I am trying to explain is the best reward for me!
Let's fucking go , I finnaly found someone that explains bloc very well :))))))))
Thanks a lot! ✨
Thank you so much! It's super clear :D
You're welcome, man, thanks! 🌟
Thanks - it explains the purpose of the different layers really well - I'm going to refactor some of my existing code and try it out now :-)
Thanks so much for your extensive feedback, let me know how the refactoring works for you in the end, looking forward
@@Flutterly The refactoring went ok, getting error messages from APIs back to the bloc was a bit tricky (eg working out which technique to use), but the overall structure looks tidy and should scale well, as I add more features. Looking forward to the next vid -)
I'm really happy that it went amazing for you, more real world app examples will come in the near future so that you can practice the architecture even more!
very good explanation, thanks!!
You should do more architectural courses!
it's was too good, thanks
Only 2 minutes in and my current way of developing webapps is being called a complete failure, this is going to be good :D
Haha, thanks for the feedback, man! ✨
Hi. Thank you so much. I'm looking forward to the 5th video.
Thank you so much! It will come soon
Thanks a alot. Your video is very great!
Thank you so much! ✨

Best explanation on the web.
I've also seen that people do an abstract Repo or ApiClient class and then like implement repoImpl or ApiClientImpl for different sources and mocking. Don't remember what class exactly, can you please explain this part also? Thanks
