What's coming

Things that are coming soon-ish to a stable release:

Material 3

You've probably heard by now that Material 3 is coming. It's been available on Flutter for some time now, by setting useMaterial3: true in your code. By the next stable release in Q4, Material 3 will be enabled by default. Now would be a good time to start migrating your code. Most all of the example code on this website has been updated to use Material 3.

New and updated docs on the site include:

• The Preparing an Android app for release page is updated to discuss how to build an Android release using an app bundle, as well as how to create separate APK files for both 32-bit and 64-bit devices.
• The DevTools docs are migrated to flutter.dev. If you haven't tried this browser-based suite of debugging, performance, memory, and inspection tools that work with both Flutter and Dart apps and can be launched from Android Studio/IntelliJ and VS Code, please check it out!
• The Simple app state management page is updated. The example code in the page now uses the 3.0 release of the Provider package.
• A new animation recipe, Animate a page route transition has been added to the Cookbook.
• The Debugging, Flutter's build modes, Performance best practices, and Performance profiling pages are updated to reflect DevTools. A Debugging apps programmatically page has also been added.

The Flutter 1.7 release includes the new RangeSlider component, which allows the user to select both the upper and lower endpoints in a range of values. For information about this component and how to customize it, see Material RangeSlider in Flutter.

Flutter 1.5 is live!

For more information on updates, see the 1.5.4 release notes or download the release.

We are updating DartPad to work with Flutter. Try the new Basic Flutter layout codelab and tell us what you think!

Flutter released version 1.2 at Mobile World Congress (MWC) in Barcelona. For more information, see the 1.2.1 release notes or download the release.

In addition, here are some recent new and updated docs:

• We've updated our state management advice. New pages include an introduction, thinking declaratively, ephemeral vs app state, simple app state management, and different state management options. Documenting state management is a tricky thing, as there is no one-size-fits-all approach. We'd love your feedback on these new docs!
• A new page on Performance best practices.
• Also at MWC, we announced a preview version of the new Dart DevTools for profiling and debugging Dart and Flutter apps. You can find the docs on the DevTools wiki (Note: since moved to this site.) In particular, check out the DevTool's widget inspector for debugging your UI, or the timeline view for profiling your Flutter application. Try them out and let us know what you think!
• An update to the Performance profiling page that incorporates the new Dart DevTools UI.
• Updates to the Android Studio/IntelliJ and VS Code pages incorporating info from the new Dart DevTools UI.
