The bloc way of decomposing apps - there are very few comparisons to MVC - discuss
MVC being 1978's Model-View-Controller of course. The site https://mvc.givan.se/ has an excellent timeline (which I made minor contributions to) and also gives the family tree for this lasting quandary as to how to separate models and views and tie them together with events.One thing I suspect isn't possible with Bloc is a single model for (say) TODO items, and two alternate views with both showing the changes to the model as they happen.Also, for Bloc to be a design pattern, you see it applied to other technologies, too. i.e. any of those listed on http://todomvc.com/ maybe. As a pattern it should definitely be applicable to other pseudo-declarative markup languages like: QML, JavaFX, TornadoFX, and maybe others. Well, I'm not encountering bloc elsewhere which makes me think it is not a design pattern.

Best design pattern for Flutter app mvvm, mvi, BloC, MVC, MVP...etc?
Hi all.We're looking to Port a Cordova SPA app to Flutter. We currently use MVC design pattern and have have had to use several 'hacks' to make it performant (like a full screen modal representing a page'.Moving to Flutter I've been reviewing various design patterns but cannot seem to find a definitive guide. Anyone messed with various design patterns? We have a feed and you swipe right to go-to native camera, swipe left to get to a chat list. You can open a chat and/or go-to a profile. There is also map view, settings page, onboarding and compose msg page.We planned to use the current SPA as a working app to copy and make our Flutter app. This is a Twitter esqe style app with lot of social sharing components, buttons etc. Full media. Anyway is there a architecture that is well suited ( best ) for this? I've seen http://fluttersamples.com/ but looking to see a more descriptive breakdown of the top few architecture recommendations for us.Thank you for any help.

Happy New Year Flutter developers!

Let's ring in the 2019 with one last #FlutterFriday by learning how to build a form with validation! Form makes it easy to save, reset, or validate multiple input fields at once.

Flutter and Augmented Reality (ARKit and ARCore)
I am fairly new to flutter so I was wondering about this. Is there a way to add augmented reality to a flutter project. Using a native library for that matter. Let's say I have in native code created a new ViewController with ARSCNView is there a possibility to display that view in flutter ? and communicating back and forth with that viewcontroller ?

Flutter and Firebase cloud functions
Hi everyone. Are there any guides/resources that teach cloud functions from the perspective of a dart developer? I know the basics of JS but I'm assuming that there is a learning curve to be able to perform more advanced tasks in the cloud
