The Flutter & Dart team just released official Agent Skills for Flutter and Dart developers. They moved away from documentation-oriented skills and focused on task-oriented skills instead.

So instead of just giving AI more documentation, these skills are designed to help agents reliably complete actual Flutter and Dart developer tasks like responsive layouts, localization setup, integration tests, pattern matching, and coverage collection.

Flutter Pro Tip #1:

If your #Flutter app supports languages besides English, don't forget to add their language codes to Info.plist file with CFBundleLocalizations key.

Otherwise, users browsing your app on App Store will just see English as app's supported language.

I've been working on a book about Flutter & Dart performance. I'm at the very beginning, with only a few chapters drafted but I decided to write the book in the open.

Here it is: https://t.co/fW9ADORhLw

@luke_pighetti Yes it is

Did you know that you can install and use multiple Xcode versions?

Here's how:

- Head to xcodereleases .com and download your desired release
- Extract and rename it
- Drag it to the /Applications folder

To switch between them, use the xcode-select CLI. 👇
