I'd like to share Thermion, an open source 3D rendering toolkit I made for Flutter and/or Dart. This came about when I needed a 3D renderer for a Flutter app[0] I was building. At the time, the only off-the-shelf option was to embed Unity, which wasn't ideal for a few reasons - unstable build process, compositing and transparency issues, and licensing uncertainty, just to name a few. In any event, frankensteining Unity (C#) together with Flutter (Dart) didn't seem like a great solution. After browsing for alternative renderers, I discovered Filament[1], an open-source, cross-platform…

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. To play with it, please visit the GitHub repo, or refer to the end of the article for detailed folders and commands. When I…

OpenUI▲322Thesys just open-sourced their generative UI rendering engine. Interesting timing given where Google a2ui and Vercel's json-render are headed. The difference worth noting: a2ui and json-render both treat JSONL as the contract between the LLM and the renderer. Thesys is betting that's the wrong primitive. Their engine uses a code-like syntax (OpenUI Lang) instead — LLM writes it, renderer executes it. The argument is that LLMs are fundamentally better at generating code than generating structured data, so you get cleaner output and ~67% fewer tokens. The broader vision seems to be a…

This proof-of-concept project combines: - Flutter, from Google; - ClojureDart, port of Clojure to Dart from Tensegritics; and - Matrix, a reactive framework from moi. So, yes, we can now program Flutter with a Lisp. Yay. Project includes dozens of working examples and a full implementation of the TodoMVC classic to help tire-kickers play around. Support installing freely available on the #matrix channel on the Clojurians Slack.

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…

Hey HN! I'm Zach from Adam (https://adam.new/). We’re building an AI co-pilot for mechanical CAD software. As part of our broader research, we built a browser-based Text-to-CAD app (https://news.ycombinator.com/item?id=44182206) and are now open sourcing it. This is a React SPA with a Supabase backend. What it does: * Generates parametric 3D models from natural language descriptions, with support for both text prompts and image references * Outputs OpenSCAD code with automatically extracted parameters that surface as interactive sliders for instant dimension…
