| <summary>Generating localizations</summary> | ||
|
|
||
| If this is the first time building the Flutter Gallery, the localized | ||
| code will not be present in the project directory. However, after running | ||
| the application for the first time, a synthetic package will be generated | ||
| containing the app's localizations through importing | ||
| `package:flutter_gen/gen_l10n/`. | ||
|
|
||
| ```bash | ||
| flutter pub get | ||
| flutter pub run grinder l10n | ||
| ``` | ||
|
|
||
| See separate [README](lib/l10n/README.md) for more details. | ||
|

| <summary>Generating highlighted code segments</summary> | ||

| flutter pub get | ||
| flutter pub run grinder update-code-segments | ||
| ``` | ||
|
|
||
| See separate [README](tool/codeviewer_cli/README.md) for | ||

| <summary>Including a new splash animation</summary> | ||
|
|
||
| 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. | ||
| </details> | ||
|
|
||
| ## Releasing | ||
|
|
||
| *must be a `flutter-hackers` member* | ||
|
|
||
| A set of GitHub workflows are available to help with releasing the Flutter Gallery, one per releasing platform. | ||
|
|
||
| 1. For Android, download the relevant [Firebase configuration file](https://firebase.corp.google.com/u/0/project/gallery-flutter-dev/settings/general) (e.g. `google-services.json`). | ||
| 1. Bump the `pubspec.yaml` version number. This can be in a PR making a change or a separate PR. | ||
| Use [semantic versioning](https://semver.org/) to determine | ||
| which part to increment. **The version number after the `+` should also be incremented**. For example `1.2.3+010203` | ||
| with a patch should become `1.2.4+010204`. | ||
|
|
||
| 1. Run GitHub workflow. | ||
| - [Deploy to web](https://github.com/flutter/gallery/actions/workflows/release_deploy_web.yml): Deploys a web build to the Firebase-hosted [staging](https://gallery-flutter-staging.web.app) or [production](https://gallery.flutter.dev) site. | ||
| - [Deploy to Play Store](https://github.com/flutter/gallery/actions/workflows/release_deploy_play_store.yml): Uses Fastlane to create a [beta](https://play.google.com/console/u/0/developers/7661132837216938445/app/4974617875198505129/tracks/open-testing) (freely available on the [Play Store](https://play.google.com/apps/testing/io.flutter.demo.gallery)) or promote an existing beta to [production](https://play.google.com/console/u/0/developers/7661132837216938445/app/4974617875198505129/tracks/production) ([Play Store](https://play.google.com/store/apps/details?id=io.flutter.demo.gallery)). | ||
| > **Note** | ||
| > Once an .aab is created with a particular version number, it can't be replaced. The pubspec version number must be incremented again. | ||
| - [Draft GitHub release](https://github.com/flutter/gallery/actions/workflows/release_draft_github_release.yml): Drafts a GitHub release, including packaged builds for Android, macOS, Linux, and Windows. Release notes can be automatically generated. The release draft is private until published. Upon being published, the specified version tag will be created. | ||
| - [Publish on Windows Store](): Releasing to the Windows Store. | ||
| > **Note** | ||
| > This repository is not currently set up to publish new versions of [the current Windows Store listing](https://www.microsoft.com/store/productId/9PDWCTDFC7QQ). Requires running `msstore init` within the repository and setting repository/environment secrets . | ||
| > See the instructions in the [documentation](https://docs.flutter.dev/deployment/windows#github-actions-cicd) for more information. | ||
| <details> | ||
| <summary>Escape hatch</summary> | ||
|
|
||
| If the above GitHub workflows aren't functional (#759), releasing can be done semi-manually. Since this requires obtaining environment secrets, this can only be done by a Googler. See go/flutter-gallery-manual-deployment. | ||
|
|
||
|
|
||
| </details> | ||
|
|
||
| ## Tests | ||
|
|
||
| The gallery has its own set of unit, golden, and integration tests. | ||
|
|
||
| In addition, Flutter itself uses the gallery in tests. To enable breaking changes, the gallery version is pinned in two places: | ||
|
|
||
| - `flutter analyze`: https://github.com/flutter/tests/blob/master/registry/flutter_gallery.test | ||
| - DeviceLab tests: https://github.com/flutter/flutter/blob/master/dev/devicelab/lib/versions/gallery.dart | ||

| # 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. | ||
|
|
||
|  | ||
|
|
||
| ## Features | ||
|
|
||
| - Showcase for `material`, `cupertino`, and other widgets | ||
| - [Adaptive layout](lib/layout/adaptive.dart) for mobile and desktop | ||
| - State restoration support | ||
| - Settings to text scaling, text direction, locale, theme, and more... | ||
| - Demo for `animations` | ||
| - Foldable support and demo for `dual_screen` | ||
| - Deferred loading | ||
| - CI/CD | ||
| - ...and much more! | ||
|
|
||
| ## Supported Platforms | ||
|
|
||
| Flutter Gallery has been built to support multiple platforms. | ||
| These include: | ||
|
|
||
| - Android ([Google Play Store](https://play.google.com/store/apps/details?id=io.flutter.demo.gallery), [.apk][latest release]) | ||
| - iOS (locally) | ||
| - web ([gallery.flutter.dev](https://gallery.flutter.dev/)) | ||
| - macOS ([.zip][latest release]) | ||
| - Linux ([.tar.gz][latest release]) | ||
| - Windows ([.zip][latest release], [.msix](https://www.microsoft.com/store/productId/9PDWCTDFC7QQ)) | ||
|
|
||
| ## Running | ||
|
|
||
| One can run the gallery locally for any of these platforms. For desktop platforms, | ||
| please see the [Flutter docs](https://docs.flutter.dev/desktop) for the latest | ||
| requirements. | ||
|
|
||
| ```bash | ||
| cd gallery/ | ||
| flutter pub get | ||
| flutter run | ||
| ``` | ||
|
|
||
| <details> | ||
| <summary>Troubleshooting</summary> | ||
|
|
||
| ### Flutter `master` channel | ||
|
|
||
| The Flutter Gallery targets Flutter's `master` channel. As such, it can take advantage | ||
| of new SDK features that haven't landed in the stable channel. | ||
|
|
||
| If you'd like to run the Flutter Gallery, you may have to switch to the `master` channel | ||
| first: | ||
|
|
||
| ```bash | ||
| flutter channel master | ||
| flutter upgrade | ||
| ``` | ||
|
|
||
| When you're done, use this command to return to the safety of the `stable` | ||
| channel: | ||
|
|
||
| ```bash | ||
| flutter channel stable | ||
| flutter upgrade | ||
| ``` | ||
|
|
||

||
| ## Development | ||
|
|
||
| <details> | ||
| <summary>Generating localizations</summary> | ||
|
|
||
| If this is the first time building the Flutter Gallery, the localized | ||
| code will not be present in the project directory. However, after running | ||
| the application for the first time, a synthetic package will be generated | ||
| containing the app's localizations through importing | ||
| `package:flutter_gen/gen_l10n/`. | ||
|

||
| ```bash | ||

| <summary>Generating highlighted code segments</summary> | ||
|
|

|
||
| 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. | ||
|
|

| `assets/splash_effects`. Ensure the name follows the format | ||
| `splash_effect_$num.gif`. The number should be the next number after the | ||
