New post on /r/flutterdev subreddit: Architecture Patterns for Flutter Applications I am looking for advice on how to structure my application directories. I want other people on my team and also my future self to be able to find the correct files to modify in the future. Are there common models, articles, maybe even a book that I can read to help me to plan out my directory structure? I am using provider for state management and it is okay. I don't feel a need to move off of it. However, I'm also not against moving off of it.I currently have this structure:guimodelnetworknotifiersI am building a front-end image management system for network images that I am pulling with http GET. I need to make many POST requests to get the desired images. The API to get the images is extensive with hundreds of options.Under gui, I have:componentsscreensI feel like I am stumbling around in the dark and that some smart people have cookbook-style examples of how I can organize my code. Does this exist somewhere?I am thinking of changing the names as follows:modelclass for image fields such as name, url, byte data for thumbnailviewcomponents (like a button)screenswindows (a portion of a screen)controllernotifiers (I'm using provider with ChangeNotifier)network (http requests)many folders with different types of API requestsIf I follow this organization, I'm not sure what to put into model.I'm practicing with smaller mobile and desktop apps first before we move to a more complex system with Firebase on the backend. We've been stuck with designing a good cloud architecture for a year. We've made lot of progress, but I've always felt that we shouldn't move our system to the cloud due to lack of a good architecture. May 26, 2021 at 12:26AM by cloudster314 https://ift.tt/2QQgT4D

New post on /r/flutterdev subreddit: An all-around ScrollingView widget for the web I was tinkering with the flutter web to see if it is good for making a website. I faced the problem of scrolling like everyone else. I tried to create a "SingleChildScrollView" replacement that has web-like scrolling abilities such as;No dragging with the mouseScroll animationScrollbarI think what I have is pretty good. I want to know if this has been done before. If it is, I would like to use it or, even better, contribute to it. If it is not, I want people to know about this because this is a fundamental need.I also want to know your opinions of it. What can be improved? What are the pitfalls?Code: WebSingleChildScrollViewGIF: SingleChildScrollView vs WebSingleChildScrollView (The first one is draggable with the mouse pointer, the second one isn't) May 26, 2021 at 01:02AM by plusturk https://ift.tt/3fjdHba

New post on /r/flutterdev subreddit: Writing an e-book but storing my book no in sql? typo: not* in SQLHello! I want to write a book with flutter but I don't think it will be long enough to store mypages in sql db. So I am just thinking of hard coding my book in a collection type like list( maybe it sounds quite stupid) but I am wondering if it is a bad practice and also if it can be revealed to my customers so that they can easily copy my book(I think it will be compiled but does this fact mean they will have difficulty checking what my code will look like easily??)​Thanks for your help and answer in advance!

New post on /r/flutterdev subreddit: Don't Provider and BLoC handle different aspects of state management? Provider is just a wrapper around InheritedWidgets, it allows me to have dependency injections anywhere in my widget tree when I have lifted state up.BLoC lets me create an interface for business logic consisting of sinks and/or streams..I can use provider to inject these into the widget tree.Unless I am missing something obvious here, I don't see why I choose one or the other..unless I use BLoC with InheritedWidget, which seems kinda dumb.

I would like to ask you how to quick implement a backend to create chats between 2 or more users on Flutter App. I found some software/web sites but they have a cost, I would like to do it for free but I think I should do it by myself using Firebase, I don't think that 3rd part software (or libraries, frameworks...) allow me to avoid this payload.

New post on /r/flutterdev subreddit: Codename One's Comparison With Flutter. Misleading? Codename One is a cross-platform framework that's been around for several years, but I'd only heard about it recently. The official site has a comparison with Flutter that seems to be misleading or even an outright lies, but I'm not knowledgeable enough about Flutter to say for sure. Any thoughts on these claims?"Flutter is an entirely separate VM which means every Flutter app pays the price of two separate VMs communicating among themselves. This means an inherent, permanent overhead in size/performance and portability that can’t be erased. ""Flutter tries to simplify the programming model by removing threading from the equation. While this does make some elements simpler, it makes other things far more cumbersome. Since native code and the physical OS use threading all profiler/debugging data is much harder to work with due to the asynchronous nature of all calls."

New post on /r/flutterdev subreddit: Is customizability more difficult with Flutter than Kotlin? Hi, I’m looking to build an app on iOS and Android and currently weighing different options (Native vs Flutter vs React Native). I think I’m probably down to Native vs Flutter.I'm fine with one design across Android and iOS but I'd like to have a few custom views and elements (custom date picker, custom calendar view, etc.). I’ve heard widgets mentioned a lot with flutter...does that mean it’s harder to create non-standard views/elements? Or is still faster to create non-standard views with Flutter than it is with Kotlin or Swift because of hot reload and other features?Sorry for the noob question, just trying to get a better understanding.
