**design doc: go/easy-cp** umbrella design doc: go/flutter-actions umbrella bug: https://github.com/flutter/flutter/issues/139604 **Sample Results**: 1. If cherry pick succeeds, a pull request with cherry pick template and label is created. https://github.com/flutter/flutter/pull/139523 2. If cherry pick fails, a comment is added under the original Pull Request. https://github.com/flutter/cocoon/pull/3305 In tests, [7d9010](7d9010c357) was used to simulate a clean cherry pick, and [cf71a5](cf71a55f7d) was used to simulate a merge conflict during cherry pick. **Implementation Details:** 1. triggered when 'cp: beta' or 'cp:stable' label is added to the original PR 4. parses release channel and gets release candidate branch name 5. get commit sha from event payload 6. checks out framework repo and revision history 7. Attempt a cherry pick without any resolution strategy 8. If cp is successful, uses a PR template to open a pull request. 9. If cp isn't successful, leave a comment on the original PR. **PR template** Since PR template doesn't support web form, the cherry pick PR template we used is https://github.com/XilaiZhang/miscellaneous-side-project/blob/master/.github/workflows/template/cherrypick.md, which is adapted from the [web form cherry pick issue template](https://cs.opensource.google/flutter/flutter/+/master:.github/ISSUE_TEMPLATE/7_cherry_pick.yml). This PR template should be reviewed and added to be under the .github path in framework repository. **Decisions Taken** 1. place of source code I put the source code under the framework repository. Acknowledges the risk of duplication of code, in favor of not needing to package and publish our own actions to market place. more details in [open discussions section of design doc](https://docs.google.com/document/d/1EUyJ9NCAltxJq3P3pIzIRVF2ArPUO4cj_eqIUvzl8cw/edit#heading=h.e3zrsz9gwxmp) 2. Resolution strategy No resolution strategy is applied at all during the cherry pick process. [more details](https://docs.google.com/document/d/1EUyJ9NCAltxJq3P3pIzIRVF2ArPUO4cj_eqIUvzl8cw/edit#heading=h.3za1b9qx6pi2) **Future Work** A PAT token is needed for authorization to create branch and add comment. We would need to create a new bot and update its credentials in the secrets section of flutter/flutter repository.
Flutter is Google's SDK for crafting beautiful, fast user experiences for mobile, web, and desktop from a single codebase. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.
Documentation
For announcements about new releases, follow the flutter-announce@googlegroups.com mailing list. Our documentation also tracks breaking changes across releases.
Terms of service
The Flutter tool may occasionally download resources from Google servers. By downloading or using the Flutter SDK, you agree to the Google Terms of Service: https://policies.google.com/terms
For example, when installed from GitHub (as opposed to from a prepackaged
archive), the Flutter tool will download the Dart SDK from Google servers
immediately when first run, as it is used to execute the flutter tool itself.
This will also occur when Flutter is upgraded (e.g. by running the flutter upgrade command).
About Flutter
We think Flutter will help you create beautiful, fast apps, with a productive, extensible and open development model, whether you're targeting iOS or Android, web, Windows, macOS, Linux or embedding it as the UI toolkit for a platform of your choice.
Beautiful user experiences
We want to enable designers to deliver their full creative vision without being forced to water it down due to limitations of the underlying framework. Flutter's layered architecture gives you control over every pixel on the screen and its powerful compositing capabilities let you overlay and animate graphics, video, text, and controls without limitation. Flutter includes a full set of widgets that deliver pixel-perfect experiences whether you're building for iOS (Cupertino) or other platforms (Material), along with support for customizing or creating entirely new visual components.
Fast results
Flutter is fast. It's powered by the same hardware-accelerated 2D graphics library that underpins Chrome and Android: Skia. We architected Flutter to support glitch-free, jank-free graphics at the native speed of your device. Flutter code is powered by the world-class Dart platform, which enables compilation to 32-bit and 64-bit ARM machine code for iOS and Android, as well as JavaScript for the web and Intel x64 for desktop devices.
Productive development
Flutter offers stateful hot reload, allowing you to make changes to your code and see the results instantly without restarting your app or losing its state.
Extensible and open model
Flutter works with any development tool (or none at all), and also includes editor plug-ins for both Visual Studio Code and IntelliJ / Android Studio. Flutter provides tens of thousands of packages to speed your development, regardless of your target platform. And accessing other native code is easy, with support for both FFI (on Android, on iOS, on macOS, and on Windows) as well as platform-specific APIs.
Flutter is a fully open-source project, and we welcome contributions. Information on how to get started can be found in our contributor guide.
