Docs updated or added since the 3.22 release

This website release includes several important updates!

• An updated widget catalog:
  • Added 37 missing widgets to the Cupertino catalog, and a new screenshot for the updated CupertinoActionSheet widget.
  • Added the new CarouselView widget.
  • CupertinoButton and CupertinoTextField also have updated behaviors.
• New guides on adding support for Swift Package Manager to iOS plugins and iOS apps. (Note that, until all of your app's dependencies are migrated, Flutter will continue to use CocoaPods.)
• Updated web docs:
  • Embedding Flutter on the web, including how to enable multi-view mode
  • Embedding web content into a Flutter app
• Update for Android 14: If you are using an Android device that runs on Android 14, you can now support Android's predictive back gesture.
• Updates for iOS 18: The iOS 18 release is in beta at the time of this release. These iOS 18 features are already enabled in Flutter and are now mentioned in the docs:
  • Use an iOS app extension in your Flutter app to create a custom toggle. Your users can then add your app's toggle when customizing their Control Center.
  • Tinted app icons are supported
• Two pages of the Flutter fundamentals docs are updated:
  • Widgets
  • Layout We hope these pages are helpful for new Flutter developers.
• DevTools also has updates. Check out the release notes for DevTools 2.35.0, DevTools 2.36.0, and DevTools 2.37.2.

• If you are interested in the new, experimental Flutter GPU API, check out the Flutter GPU blog post.
• The Flutter wiki has been divided up and moved into the relevant GitHub repos, making it easier to keep that info up to date.

Flutter 3.22 is live! For more information, check out the Flutter 3.22 umbrella blog post and the Flutter 3.22 technical blog post.

You might also check out the Dart 3.4 release blog post. In particular, Dart now provides a "baked in" language macro, JsonCodable, for serializing and deserializing JSON data. A future (and unspecified) Dart release will allow you to create your own macros. To learn more, check out dart.dev/go/macros.

Docs updated or added since the 3.19 release

• A new 7-page section on Adaptive and Responsive design. (This replaces our previous, somewhat scattered, documentation on this subject.)
• For new-ish Flutter developer who has worked through the first Flutter codelab, we've added some "what's next" advice on how to move beyond that initial step. Check out the Flutter fundamentals docs.
• Our Flutter install docs have been revamped.
• We have three new codelabs and a new guide for the Games Toolkit. To see the list of additions, check out the updated Casual Games Toolkit page.
• A new section, Conditionally bundling assets based on flavor, in the Flavors page.
• Flutter support for Web Assembly (Wasm) has now reached stable. To learn more, check out the updated Support for WebAssembly (Wasm) page.

• You might also have noticed that the App solutions submenu in the sidenav now has an AI section, and an enhanced Monetization section, to name some of the changes.
