guidance for developers who write large-scale, complex
Flutter apps. Well, that work has begun:
introducing [Architecting Flutter apps][]!
This section includes eight new pages about architecting
Flutter apps, including a [Design patterns][] page
that has six recipes for common design patterns
that you might find useful.

[Support for WebAssembly (Wasm)][].

Besides updates to several pages, check out the new
[Intro to Dart][] page.

Specifically, you can now build on the stable channel for SwiftPM,
however, plugins will continue to be installed using
CocoaPods as the SwiftPM feature remains
unavailable on the stable channel:
[Swift Package Manager for plugin authors][plugin-authors] and
[Swift Package Manager for app authors][app-authors].

migration info.

**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.
For more information,
check out the following resources:
* [Flutter 3.13 blog post][blog-material]
* [Material Design for Flutter][] page
**Impeller for Android**
Progress continues on Impeller for Android.
For more information, check out the
[Flutter 3.13 blog post][blog-impeller].
**New scrolling APIs**
We have been working on updating our scrolling APIs.
The rework will eventually result in 2D scrolling
support for trees and tables, even diagonal scrolling!
Flutter 3.13 also provides new Sliver classes for fancy scrolling.
For more information, check out the
[Flutter 3.13 blog post][blog-scrolling].
**Updates to the Games toolkit**
We are working on updates to the Flutter Games toolkit,
including the sample code, additional docs, and a new video.
The Games toolkit is developed independently of the
Flutter SDK, so stay tuned for updates as they are ready.
For more information,
check out the [Flutter 3.13 blog post][blog-games].

We have new codelabs since the last stable release:
* [Your first Flutter app][]
Learn about Flutter as you build an application that
generates cool-sounding names, such as "newstay",
"lightstream", "mainbrake", or "graypine".
The user can ask for the next name, favorite the current one,
and review the list of favorited names on a separate page.
The final app is responsive to different screen sizes.
(Note that this codelab replaces the previous "Write
your first Flutter codelab for mobile, part 1 and part 2.")
* [Using FFI in a Flutter plugin][] _(Now archived)_
Dart's FFI (foreign function interface) allows Flutter apps
to use of existing native libraries that expose a C API.
Dart supports FFI on Android, iOS, Windows, macOS, and Linux.
* [Building a game with Flutter and Flame][]
Learn how to build a platformer game with Flutter and Flame!
In the Doodle Dash game, inspired by Doodle Jump,
you play as either Dash (the Flutter mascot),
or her best friend Sparky (the Firebase mascot),
and try to reach as high as possible by jumping on platforms.
* [Add a user authentication flow to a Flutter app using FirebaseUI][]
Learn how to add Firebase Authentication to your Flutter app
using the FlutterFire UI package. You'll add both email/password
and Google Sign In authorization to a Flutter app. You'll also learn
how to set up a Firebase project,
and use the FlutterFire CLI to initialize Firebase in your Flutter app.
* [Local development for your Flutter apps using the Firebase Emulator Suite][] _(Now archived)_
Learn how to use the Firebase Emulator Suite with Flutter during local development,
including how to use email-password authentication with the Emulator Suite,
and how to read and write data to the Firestore emulator. Also, you'll import
and export data from the emulators, to work with the same faked data each
time you return to development.
In addition, we've updated all of our existing
codelabs to support multiplatform.
The [codelabs & workshops][] page is updated
to reflect the latest available codelabs.

New pages include an [introduction][],

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.
If you have questions or comments about any of these docs,
[file an issue][file-issue].

## 05 Nov 2018: new website
Welcome to the revamped Flutter website!
We've spent the last few months redesigning the website and how its
information is organized. We hope you can more easily find the docs
you are looking for. Some of the changes to the website include:
* Revised [front][] page
* Revised [showcase][] page
* Revised [community][] page
* Revised navigation in the left side bar
* Table of contents on the right side of most pages
Some of the new content includes:
* Deep dive on Flutter internals, [Inside Flutter][]
* [Technical videos][]
* [State management][]
* [Background Dart processes][]
* [Flutter's build modes][]
If you have questions or comments about the revamped site,
[file an issue][].
