I maintain open source packages for Flutter and Dart, mainly Jaspr and dart_mappable. 💙🎯
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🔎 Report outdated/wrong code as lint warnings
🪄 Auto-regenerate outdated/wrong code via 'dart fix'

Posing with the architect of a genocide for sales leads is an insane and deeply immoral stance

🎯 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.

Only one week left until Fluttercon!
I got some very cool Jaspr features lined up, so let's see how many I can pump out until then. 😁
I'll keep this thread updated. 🧵

Come contribute to Jaspr, its super easy!
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

- better language support
- massively reduced internal complexity

📣 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. 👇

I'm thinking about ordering some stickers for Fluttercon Berlin, but I noticed they cost money (what?) so please sponsor me on Github -> github.com/sponsors/sch... 🙏
I will also make a special sticker just for my sponsors then. 💙

Just take the pub package url and put '.schultek.' between 'pub' and 'dev'.
