A while ago I watched Jérémie Chassaing’s lecture about functional domain modelling.

It was beautiful.

The Fraktalio team (Ivan Dugalic) did an amazing job and brought those ideas to Kotlin, Rust, and TypeScript.

For a while I’ve been a fan of the Dart programming language. Why? It’s a bliss to work with:

• Easy to pick up — if you know Java, TypeScript, C#, Objective-C, C++, or C, you can more or less start writing Dart right away;
• Strong static typing;
• Null safety;
• All you need is the dart command-line tool — it supports testing, analysis, compilation, and publishing, with both JIT and AOT compilation options;
  • no Gradle, no IntelliJ IDEA, and little other heavyweight tooling required;
• Hot reload during development (especially with Flutter) means you do not have to wait for a full compile cycle to see whether your change works;
• The Dart team added the dart mcp-server command, which makes it much easier to work with AI agents;
• It is battle-tested in production: customer-facing Google products such as AdWords and AdSense use AngularDart; other Google teams also ship Dart in production (see dart.dev);
• The Flutter framework is built on Dart and lets you target iOS, Android, Linux, Windows, macOS, and the web (including WebAssembly) from one codebase;
