New post on /r/flutterdev subreddit: Full-stack development with Flutter/Dart? Anyone has experience creating both back-end and front-end using Dart (and UI with Flutter)? Flutter + Firebase don't count.There're several back-end frameworks out there (Angel, Aqueduct, Shelf) - would be interested to see if someone actualy used them (or any other). Comparing of conventional frameworks you dealt with in the past(i.e .NET/ASP.NET, Java, PHP) to Flutter/Dart back-end experiences is appreacted.

New post on /r/flutterdev subreddit: Flutter app’s state in Isolate There are many ways to manage state in Flutter, but most of them are built in such a way that all the logic is executed in the main isolate of your application. Execution of network requests, working with WebSocket, potentially heavy synchronous operations (like local search), all this, as a rule, is implemented in the main isolate. This article shows other doors as well. March 14, 2021 at 11:13PM by bitter-cognac https://ift.tt/3tlEgRs

New post on /r/flutterdev subreddit: Flutter 2.0, shout out to the Flutter Team!!! In my over 3 decades work as a developer I have never upgraded my development environment to a major upgrade in such a short period of time. Outstanding!!!I put aside the day to upgrade a large app I've spent the better part of a year working on. After 20 minutes of updating on pub, and 2 small code changes I ran flutter upgrade, and got nervous. I've been running tests for an hour, and now I'm going to play the rest of the day.Again, thank you Flutter Team!!! PS: I spent 17 years on Delphi 7 because we could never upgrade our entire suite of apps to Delphi 8...10... March 14, 2021 at 04:50PM by jrheisler https://ift.tt/3eBCI1m

New post on /r/flutterdev subreddit: New Flutter Flame Tutorials to Make Mobile Games Flame is a 2D game framework for Flutter. It is on version 1.0.0-rc8.I've added two new tutorials to my series on FlameIntegrate Flutter Widgets into Flame Mobile Games - shows how easy it is to add Flutter icon buttons to Flame mobile app gamesFlame Audio in Flutter Mobile App Games - flame_audio is a separate package and not included in the base flame packageI also added a "What is Flame and Who is it For" video as an intro to the series.After I received some nice questions, I realized that people might not be familiar with Flame. Here are the basics.Flame is an open source 2D game engine for Flutter.Flame is for people who like Flutter and Dart.There's no real feature advantage using Flame over Unity or Phaser (JavaScript). The only advantage of Flame is that it is the Dart and Flutter workflow.Flame is moving to 1.0 and the documentation and many tutorials may be outdated. If you want to use the pre-release 1.0 Flame framework, these simple tutorials may help you dip your toe into Flame.Performance of Flame is good. Graphics and sprite animation are of the quality you would expect from Flutter apps, which is great IMO.I believe Flame does run on desktop and web in addition to mobile, but I only use Flame on mobileI am building these video tutorials as a hobby as I am sheltering-in-place in California and I enjoy the interaction with people online. Flame is good if you want to learn more about Flutter and Dart.Here are some benefits to learning Flame:As the site documentation is a bit outdated due to the transition to 1.0, you will need to read the source code of the Flame libraries with CTRL-CLICK when you are coding. This is actually a nice way to learn more about constructors which can go pretty deep with Dart.For the same reason as above, you will learn more about mixins and extensions, including ideas on how to write them yourselfif you are new to game development, learning about game development can help you understand and optimize other types of animations in Flutter business apps. This is not a direct connection, but if you understand updates and rendering more deeply, it may give you ideas to improve your business apps and make them more delightful or engaging.The Flame engine and components themselves are great, so if you power-through the sparse documentation problem, then building the app is gratifying because the actual game will be pleasant to use and beautiful.You can also put all those beautiful Flutter widgets into Flame. It feels great to have these pre-built components that just drop in with little effort.Hope everyone is trying to keep motivated and stay positive during COVID health restrictions. It's tough, but let's keep trying our best to improve things. March 14, 2021 at 03:16PM by codetricity https://ift.tt/3bMnWmC
