New post on /r/flutterdev subreddit: Anyone developing with Flutter using a Linux or Windows ARM environment? I know that Flutter development works fine on M1 Macs, but curious how (and if) it works on ARM Linux distros or even Windows for ARM. I've seen some discussion saying it should work, but haven't actually heard reports. October 12, 2021 at 03:54AM by mattmaddux https://ift.tt/2YMQlp1

New post on /r/flutterdev subreddit: LoRa and nbIoT with Flutter app I'm pretty used to using ble with Flutter, but I'm wondering how to go about using LoRa (LoRaWan) and/or nbIoT (narrow band IoT). I'm not really seeing any packages in dart pub, so figured I'd ask and see how others have done it. Any info would be really appreciated. Even articles to read or anything like that. Thanks!

New post on /r/flutterdev subreddit: Is there any Flutter Sleep API or Plugin? Hi guys, so I have to make an app with the functionality of Sleep API, and I couldn't find any documentation in regards to it or any Github app except this one "https://github.com/LihanZhuH/Sleep-Organized" . but overall, I'd appreaciate any help I could get.Also, would I have to use Method-Channels to use the android Sleep API if there isn't a package/plugin available and has anyone done it yet?

New post on /r/flutterdev subreddit: Given the interest in the last post, the high-level memory-safe binding generator for Dart/Flutter <–> Rust is open-sourced now ;) Since the interest my last post and this post asking whether interested in open-sourcing this, I have spent some days polishing it and it is published now!GitHub repo: https://github.com/fzyzcjy/flutter_rust_bridge----------------------Following is a very brief introduction for the lib:Want to combine the best between Flutter, a cross-platform hot-reload rapid-development UI toolkit, and Rust, a language empowering everyone to build reliable and efficient software? Here it comes!FeaturesMemory-safe: Never need to think about malloc/free.Type support: Unlike low-level binding generator which only provide primitives and pointers, this package provides things like Vec<u8>(Uint8List), Vec<T>(List<T>), any custom struct(class)s, and even recursive structs (e.g. a tree node).Zero-copy: Pass big array of bytes from Rust to Dart without any memory copies.Async programming: Simply call functions directly in main isolate (thread) of Dart/Flutter, and Rust code will not block the Flutter UI.Easy to use: All you need to do is write down your Rust code. The code generator will do everything and expose an API in Dart/Flutter's style.Lightweight: This is not a huge framework that includes everything, so you are free to use your favorite Flutter and Rust libraries. _{For example, state-management with Flutter library (e.g. MobX) can be elegant and simple (contrary to implementing in Rust); implementing a photo manipulation algorithm in Rust will be fast and safe (countrary to implementing in Flutter).}Easy to code-review & convince yourself: This package simply simulates how human beings write down boilerplate code. If you want to convince yourself (or your team) that it is safe, there is not much code for you to look at. The runtime is only hundreds of loc, and the generated code follows simple patterns. No magic at all! (More about safety concerns.)Pure-Dart compatible: Despite the name, this package is 100% compatible with pure Dart. It does not require anything specific to Flutter. See this pure-Dart example.Simple exampleWhat you write down (in Rust):

pub fn my_function(a: MyTreeNode, b: SomeOtherStruct) -> Result<Vec<u8>> { ... do my heavy computations ... } // you can use structs (even recursive) pub struct TreeNode { pub value: String, pub children: Vec<MyTreeNode> } 

With bindings automatically generated, you can simply use the following API in Flutter/Dart. Nothing more.

Future<Uint8List> myFunction(MyTreeNode a, SomeOtherStruct b);
