New post on /r/flutterdev subreddit: I made a gaming social network using Flutter This post is not a list of the pros and cons of Flutter, I'm just sharing my experience.The project (I don't think I can post a link in the post so I'll post a comment with it)Long story short: I started learning coding on Reddit and after a few months I got a job as Android developer, but lost it because of the pandemic. Three of us got along really well so we wanted to create something together.We've created a social network that in the idea is kind of a Twitter and Reddit hybrid dedicated to gaming. Some of the features (a lot more are to come) :Your followers can follow your activity and be notified when you are live on Twitch.You can create and follow events: whether it's a special streaming event, a gaming night with friends or a big Esports event.You can also post news and gameplay on a game's feed, the content will be visible to all followers of that game. ... and many other things. The app is in Beta, we are working on new features and a PC version. DevelopmentWe are one Devops, and two devs. My friend is mostly focused on the backend part and I work on the mobile and desktop apps. It was crucial for us to release the app on Android and iOS (and a bit later on desktop) fast enough with decent performance. But we didn’t have much time and we had limited resources so going native was not a viable solution. I gave Xamarin, React and Flutter a try and of course I picked the later. Even if React was more mature I chose Flutter because I had a better experience with it building a toy app, and because of the amazing community.ArchitectureI tried to copy what I was used to for Android development: MVVM with a pragmatic approach of Clean Architecture.To sum it up: Datasource > Repository > Use case (where I do logic not related to the UI) > ViewModel (where I do logic related to the UI, this is a ChangeNotifier and I use Provider for state management) > UI (with no logic). With GetIt as a service locator.It's probably far from being perfect but it works for me, I have no problem to add features or to test, and that's the point.The worstRegarding features what I've struggled the most with lately was handling videos in a feed, mostly on Android. I had either poor performance or crashes. I ended up having only one instance of the video player at the time and I init it based on percentage of visibility and scroll velocity. But the behavior was different on both platforms so we have one player for each at the moment. We improved loading time with compression using FFMEG.Regarding Flutter, updating dependencies is a real nightmare. EVERY time I update there is trouble on iOS and I need to clear folders or update values here and there.The bestIt's really pleasant to code UI, if I ever have to go back to Android development I would have a hard time (or not with Compose!).StackFront: Flutter Back: Golang, Gorilla, vanilla SQLAll in all I'm happy to have picked Flutter, and I'm really confident for its future. The app has reached beta quality on mobile and an alpha release of the desktop version should be available in the coming months. Please comment if you have any questions!

New post on /r/flutterdev subreddit: How many are too many packages? No seriously I know it's efficient and all and like saves time and money but when are you using too many packages it becomes a liability?

New post on /r/flutterdev subreddit: Help me build a Flutter skill tree package Hello ! I'm making my fourth Flutter package but I need help as I suck with graph theory and all that. I'm curious to know if anyone would like to offer their time to help me build an MIT licensed package to build arbitrary skill trees like for games and such.The base code is laid out and I've got basic nodes showing on screen (not in a pretty way). I'd mostly need help with a code review of my graph stuff as well as examples of skill trees and possible ways we could make them using the package. My code is documented and the readme has been mostly written to give users an idea of what I'm trying to make. I'm also open for general discussion too if you want to just want to open an issue and suggest changes.

New post on /r/flutterdev subreddit: how to adapt figma sizes to in flutter app? I have design Figma, I need to apply this in my flutter app. but I have certain difficulties, so in order.The first thing I tried was to use auto import tools, I tried:Adobe XD to FlutterSupernova StudioUnfortunately these tools are still at the beginning of their journey. they provide some benefit, but do not give full importsAlso I use several plugins for Figma:Figma to flutterFigma to codebut the capabilities of these plugins are also limited. I realized that I need to do it myself.Figma page dimensions are 320 px. Device screen sizes will vary. but I need it to look as close as possible. I decided to use the "proportional approach". I am using the dimensions of the figma elements with the following extension:

 //SizeConfig screenWidth = _mediaQueryData.size.width; screenHeight = _mediaQueryData.size.height; extension SizeDoubleExt on double { double h() { double screenHeight = SizeConfig.screenHeight; var res = (this / 693.0) * screenHeight; return res; } double w() { double screenWidth = SizeConfig.screenWidth; var res = (this / 320.0) * screenWidth; return res; } } //example return Container( width: 80.w(), ); but the result does not satisfy me. maybe I need to consider devicePixelRatio(logical pixel), or the "proportional method" is wrong. The main question is how do I adapt the dimensions(sizes) of the figma to the sizes of different devices? any advice - I would be very grateful.
