-# Flutter Gallery
+The Flutter Gallery has moved to [https://github.com/flutter/gallery].
 
-Flutter Gallery is a resource to help developers evaluate and use Flutter.
-It is a collection of Material Design & Cupertino widgets, behaviors, and vignettes
-implemented with Flutter. We often get asked how one can see Flutter in action,
-and this gallery demonstrates what Flutter provides and how it behaves in the
-wild.
-
-![Flutter Gallery](https://user-images.githubusercontent.com/6655696/73928238-0d7fcc80-48d3-11ea-8a7e-ea7dc5d6e713.png)
-
-## Supported Platforms
-
-Flutter Gallery has been built to support multiple platforms.
-This includes:
-
-- Android
-- iOS
-- web
-- macOS
-- Linux
-- Windows
-
-That being said, extra steps must be taken to [enable Desktop support](
-https://github.com/flutter/flutter/wiki/Desktop-shells#tooling). For
-example, to run the macOS app:
-
-```
-cd gallery/
-flutter config --enable-macos-desktop
-flutter create .
-flutter run -d macos
-```
-
-Additionally, the UI adapts between mobile and desktop layouts regardless of the
-platform it runs on. This is determined based on window size as outlined in
-[adaptive.dart](lib/layout/adaptive.dart).
-
-## To include a new splash animation
-
-1. Convert your animation to a `.gif` file.
-   Ideally, use a background color of `0xFF030303` to ensure the animation
-   blends into the background of the app.
-
-2. Add your new `.gif` file to the assets directory under
-   `assets/splash_effects`. Ensure the name follows the format
-   `splash_effect_$num.gif`. The number should be the next number after the
-   current largest number in the repository.
-
-3. Update the map `_effectDurations` in
-   [splash.dart](lib/pages/splash.dart) to include the number of the
-   new `.gif` as well as its estimated duration. The duration is used to
-   determine how long to display the splash animation at launch.
-
-## Generating localized strings and highlighted code segments
-
-To generate localized strings or highlighted code segments, make sure that you
-have [grinder](https://pub.dev/packages/grinder) installed. You can install it
-by getting the packages in `samples/gallery/`:
-```
-flutter pub get
-```
-
-To generate localized strings (see separate [README](lib/l10n/README.md)
-for more details):
-
-```
-flutter pub run grinder l10n
-```
-
-To generate code segments (see separate [README](tool/codeviewer_cli/README.md) for
-more details):
-```
-flutter pub run grinder update-code-segments
-```
-
-## Creating a new release (for Flutter org members)
-
-1. Bump the version number up in the `pubspec.yaml`. Use semantic versioning to determine 
-   which number to increment. For example `2.2.0+020200` should become `2.3.0+020300`.
-   
-2. Create a tag on the `master` branch of this repo in the form of `gallery-v2.3`.
-	* `git tag gallery-v2.3`
-	* `git push --tags`
-
-3. Publish the web release (using the [peanut package](https://pub.dev/packages/peanut)).
-    * `flutter pub global activate peanut`
-    * `flutter pub global run peanut:peanut`
-    * `git push upstream gh-pages:gh-pages`
-        * `git update-ref refs/heads/gh-pages upstream/gh-pages` if you need to align with upstream.
-
-4. Publish the Android release (using the correct signing certificates).
-    * Create the app bundle with `flutter build appbundle`.
-    * Upload to the Play store console.
-    * Publish the Play store release.
-    * Create the APK with `flutter build apk` (this is for the Github release).
-
-5. Draft a release in Github from the tag you created, call the release `Flutter Gallery 2.3`
-    * Upload the Android APK from above.
-    * Create and upload the macOS build by running `flutter build macos` and zipping the 
-      app inside `build/macos/Build/Products/Release`.
-    * Optional: Create and upload the Linux/Windows builds.
-    * Publish the release.
+The new URL for the Gallery running on web is [https://flutter.github.io/gallery].
