   Rust GUI Library via Flutter▲301

   Hi, I made a bridge (https://github.com/fzyzcjy/flutter_rust_bridge v2.0.0) between Flutter and Rust, which auto translates syntaxes like arbitrary types, &mut, async, traits, results, closure (callback), lifetimes, etc. The goal is to make a bridge between the two, seamlessly as if working in one single language. Then, as an example, I showed how to write Rust applications with GUI by utilizing Flutter. That is discussed in the link in details.

   I made a CLI tool to create web extensions with no build configuration▲381

   Hello HN! I'm the creator and solo developer of Extension.js, a development tool for browser extensions with built-in support for TypeScript, WebAssembly, React, and modern JavaScript. Developers use it to spend less time configuring the compilation config or learning new frameworks and more time actually writing code. Most projects similar to Extension.js rely on some sort of abstraction or configuration to get started, making the initial development process slow given the extra learning curve and setup guidelines. By using Extension.js, adding the package to your npm scripts is all it…

    Shorebird 1.0, Flutter Code Push▲153

    Hey HN. Eric Seidel here (former lead of Flutter & Dart at Google, prev. YC S06). I founded Flutter and led the team for almost a decade. One of the constant questions we got was would we support code push like the web/react native: https://github.com/flutter/flutter/issues/14330 I left Google about a year ago and set out to build a company around Flutter and decided to start with code push. It took us a year to build. We had to build a new toolchain for Dart and a custom interpreter (for store compliance). But it works! Our beta has already been used by…
