New post on /r/flutterdev subreddit: Flutter performance for music app? Hello, I've been working on a music app (something akin to "Simon".) Building it is a hobby/labor-of-love, but I do intend to eventually charge for it. My background is in JS/React.I started building originally in Android Native. Performance was great, but I found development quite slow, and considering that I would likely find iOS native dev slow also, decided to try React Native.Alas, RN turned out have totally unacceptable performance on my phone (an admittedly older Samsung Galaxy Halo.) The app is timing-intensive and measures rhythm exactly, and the RN build was noticeably laggy. (A bummer, since I know React pretty well.)I've been informed that RN performance should be better on new phones, but I'd like to build in an environment where I really don't have to worry about it. So I've been considering Flutter. Reviews have stated that it performs overall better than RN ("aiming for 60fps"), if not quite as perfectly as a native app.So I wanted to check with Flutter devs to make sure I'm making the right call here. Here is what my app will need:- Metronomic precision for timing user taps and playing samples (managed by an animation loop) - A mostly-static screen with some minor/intermittent visual animation (eg: a little bird flies by upon completion of a level) - Accompanying background musicOverall the project is fairly simple, I just really want to make sure it can do these things well before I plunge in and spend untold hours learning a new framework. Should I go for it with Flutter, or accept that I will need to slog through building two native apps to make this work?Thanks so much for your time and honest opinions!

I created a template for building apps with JWT Authentication, so when building a new project, you can just start from that point, without needing to build everything from scratch.It's fully open source, so feel free to use it on your projects.Also, if you think that something could be better, contribute and make the project better for the whole community.If this helps, please consider starring it.Thanks!Link to repo: https://github.com/Enzodtz/flutter-jwt-auth-template February 21, 2022 at 10:25PM by enzodtz https://ift.tt/YUJnsHe

New post on /r/flutterdev subreddit: By FAR my biggest pain with developing flutter is xcode build errors related to my firebase dependencies. Am I the only one who has this problem? Because it is driving me bonkers.I use firebase services in my app, and building on iOS is a terror and anxiety inducing experience, because I never know when I am going to get some obscure build error related to one of my firebase dependencies.I have quite commonly recieved obscure build errors related to firebase and pod install procedure, or xcode build. Usually something to dop with some module.It seems like the only way to build a flutter developer is to become an absolute expert on the ios and pods build system and dependency management./rant February 21, 2022 at 09:10PM by reddittrollguy https://ift.tt/p7yz1X4

New post on /r/flutterdev subreddit: Flutter and Job Vacancies Hello, no doubt Flutter is an amazing framework, fast,and so promising… but why there is a shortage/lack of vacancies compared to other cross-platforms?Compared to React Native, the job market is exploding(thanks to expo)… while flutter is not…Is it me seeing a shortage in jobs or there is a reason behind this?

New post on /r/flutterdev subreddit: Where/What should I learn next? - Begginner here (backend) Hey y'all, so, I know I'll look ridiculous writing this on this subreddit, but I consider myself almost a complete begginer. I'm now on my second "masterclass" app video, as the first one was a WorldTimeApp (By Net Ninja) that I followed but wasn't able to finish as some things that he used weren't able now (tutorial is 2+ years old, some things are no longer up and running).I figured out that I'd try another one of these longer tutorials, as I've been really enjoying all of this, and it's all quite new to me (all my coding background comes from a scratchy ass subject i had in high school).I've picked this 4hr long tutorial by "dbestech" (link: https://www.youtube.com/watch?v=x4DydJKVvQk&t=5460s), and it was going incredible till I hit a wall (at around 3:10:00). We've come to what I think is the start of the making of the backend portion of the app, and I can't baically understand a thing of what he's doing, what software he's using, and the whole setup process. Not to blame on him, the whole tutorial is great, it's just that I have 0 knowledge on this part.With this, could someone tell me what or/and where to iniciate my learning progress in this area? Like what I had to learn so I could follow the rest of the tutorial? (I've watched all over his channel and did not figure out anything that could help me). It doesn't have to specifically the method of this tutorial, just anything that could help me out start learning about this whole other dimension to appdevelopment.Cheers to y'all, have a great day!P.S: I've also published this on r/flutterhelp, just figured out I could post here too as they are so much people online.

New post on /r/flutterdev subreddit: Late variable declaration can access members in its initializer 🤯 I just discovered that if you declare a variable with late, you can access members of the class in its initializer. Can someone explain me why it's working and if it's safe to do so instead of using initState ?

class _ExampleState extends State<Example> with SingleTickerProviderStateMixin { _ExampleState(); Duration get computeDuration => const Duration(seconds: 1); // Error: computeDuration can't be accessed in an initializer // Error: invalid reference to this final AnimationController finalController = AnimationController( duration: computeDuration, vsync: this, ); // Working late AnimationController lateController = AnimationController( duration: computeDuration, vsync: this, ); }
