Google suggests the use of the BLoC pattern to manage the state of a Flutter app. I have read that together with rxdart, it is the most convenient and complete way to manage the state. So, I would like to understand and learn that pattern.
Unfortunately, it seems that there is no complete and exhaustive documentation. Can somebody explain to me clearly this pattern and its implementation in a Flutter app?
Thanks!
If you are still interested in this topic I would recommend flutter_bloc library and its official documentation. It makes working with this pattern a real pleasure. If you will be looking for more practical usage of this library I have recently written a blog post on this topic.
Here some helpful links.
Those are explanations with examples made by Didier Boelens :
The basics with streams and BLoC pattern (Reactive Programming - Streams - BLoC)
A bit deeper and practical exemple (Reactive Programming - Streams - BLoC - Practical Use Cases)
A comparison between BLoC, ScopedModel and Redux (BLoC - ScopedModel - Redux - Comparison)
It helped me a lot and I hope you will find what you want too.
You can check this article - Bloc pattern for Flutter on the classic counter example.
There is clear explanation of BLoC and working example of "classic" counter app rewritten with BLoC pattern.

Sorry I am pretty inexperienced with ARKit. I am working on an app and it will have more features later but the first step would basically be recreating the measure app that is included with iOS. I have looked at the documentation that Apple gives and most of it is for stuff like face tracking, object detection, or image tracking. I wasn't sure exactly where to start. The rest of the existing code I have now is written in SwiftUI if that matters. Thank you!
Understand that it can be quite confusing in the beginning. I would recommend to walk throught the toruial at raywenderlich.com. This toturial from Codestars on Youtube is also very good if you like to listen and watch instead of reading. Both talks go throught a lot of important parts of ARKit so I really recomend it. After that you problably have a create understanding and you clould watch Apples WWDC2019 talk What's new in ARKit 3.
Hope I understood your question correctly and please reach out if you have any questions or other concerns.
Could someone please point me to some tutorial or provide an example code snippet about how to create a diagram/flowchart in Dart? The simple scenario would be to have couple of elements connectable to each other and possibility to read which one is connected where. There are tons of JS examples but for learning purposes I would like to go the Dart way :)
I've been using a wrapper around an JS GraphViz library for a number of projects.
See https://pub.dartlang.org/packages/pubviz - Here's the output: http://kevmoo.github.io/pubviz/
Also https://pub.dartlang.org/packages/gviz
It's not super interactive or anything, but it's useful when you just want to visualize a graph structure.
While I am quite new to the Apple developing stuff, coming from a long front-end dev career, I'm wondering if there's any better option than just using a function like refreshUI when I receive data from server.
I'm used to stuff like RactiveJS, Angular ( stuff based on handlebars which updates automatically in the interface when giving it a new value )
Any ideas or knowledge about that ?
I could be stupid or maybe I don't know what to exactly search for on google.
Yes you are in luck!
By far the most common and well supported library for this in iOS is Reactive Cocoa:
https://github.com/ReactiveCocoa/ReactiveCocoa
The learning curve may be a bit steep but its well worth it in my opinion.
Since you're using Swift, SwiftBond is where it's at
https://github.com/SwiftBond/Bond
Alternatives to explore:
Reactive Cocoa
RxSwift
DIY via a combination of
-- Key value observing
-- UINotificationCenter
-- MVVM design patterns
-- Closures
Don't take the above as exhausting, I am in the process of figuring out myself the best course of action.
I recently watched great google talks speech about Cling - C++ language interpreter. But I wonder if anyone except people at CERN (where it is developed) are using Cling, and how good it is from non-collider-physics-scientist point of view, can you write desktop apps with it?
There are some videos of uses cases different from the High Energy Physics: http://www.youtube.com/results?search_query=cling+c%2B%2B (I think first couple are the relevant ones)
It has the potential to be very useful, but it is very young. There is no documentation that I could find, no dedicated mailing list, no online tutorials. I was able to get small toy code to run, but couldn't figure out how to use it productively on a large library yet.
Cling project is well established one. You can find more information in their official website cling. They also have a forum
Thanks
I have started working on Corona SDK.As you all know it uses Lua as the programming language,i wanted to know some good links or ebooks which i can refer to begin development.I am an iPhone developer and working on objective C since last 1 year.
Any suggestions,help would be appreciated.
Thanks
Aditya
I've been using this: Programming in Lua, first edition (FREE online edition of the book)
The Corona SDK forums are also good for specific issues related to the SDk itself. It seems it is having a few database problems just right now, but you might want to check it later.
Edit: just for completeness, here is the link to the Lua Bookstore # amazon (not an affiliate link).
You can also check out http://learningcorona.com/ which has a huge listing of tutorials for Corona.
Here's a great resource for learning Lua, it's aimed towards beginner programmers (doesn't sound like you), but it does a great job at introducing Lua and most of the basic concepts:
Lua for Beginners:
http://lua.gts-stolberg.de/en/index.php?uml=1
That, as well as the "Learning Corona" section of the Ansca docs should be plenty enough to get you up to speed in a very short amount of time:
http://developer.anscamobile.com/resources/docs/
TIP: Start working on a project, or converting an existing app using Corona and you'll learn it blazing fast! That's what I did, and I learned it quickly enough to have one of my games fully converted in about 8 days.
For understanding basics of CORONA SDK I will prefer "Corona.SDK.Mobile.Game.Development.Beginners.Guide"
book from Packtpub publication.
and You can also check out http://www.learningcorona.com/ for tutorial both video and audio.
The Lua Reference Manual is also an excellent read: Concise and complete.
Lua Gems is also worth looking at (at least the freely available snippets).
I found the Beginning Lua Programming book to be pretty good as a complete reference for Lua with good example code.
My very personal advice is just take a look at great books (Programming in LUA is covering everything) and switch as soon as possibles to samples / tutorials in order to learn all the API functions.
There are several Corona sdk video tutorials on YouTube. One demonstrates how to create a simple balloon game in a few minutes. You can have Your Lua editor in one window and YouTube in another, and click on the video to start/stop and switch to the editor and type in the code. Some tutorials provide links to download the code.
hello you can use their website they have good documentation you will find it here
