We need to provide more use-cases, frameworks, and learning material for Dart without Flutter. We need less “Flutter Developers” and more “Dart Developers skilled in Flutter” But how do we get them started? What’s some other good Dart frameworks to start with?

I've been experimenting with using the new analyzer plugin API for code generation, and it's actually really cool! ⚡️ Instant code generation 🔬 Surgical updates in the same file 🔎 Report outdated/wrong code as lint warnings 🪄 Auto-regenerate outdated/wrong code via 'dart fix'

🎯 Introducing Component Scopes for Jaspr! With the newest release, you get live in-editor hints on where a component is rendered (server, client or both) and whether it uses unsafe imports. This is solving one of the biggest pains when working with full-stack components 👇

Jaspr + Riverpod = 💙 jaspr_riverpod is not updated to use Riverpod 3, giving you access to all the latest features. Also, syncing providers is now even easier. Think "fullstack providers" that you compute on the server (e.g. load from db) and read on the client after pageload.

I'm so happy how a seemingly simple change (changing Iterable<Component> to Component) has such a big impact: - easier and more familiar syntax - better language support - massively reduced internal complexity - better performance - easier to maintain and contribute

📣 I published a new Jaspr pre-release with big improvements! Writing Jaspr components is now even easier and more Flutter-like, the framework core is further optimized and more performant, and I added a 'jaspr migrate' command that automatically migrate all breaking changes. 👇
