In general, our philosophy is to update the `stable` channel on a quarterly basis with feature updates. In the intervening period, occasionally we may decide a bug or regression warrants a hotfix. We tend to be extremely conservative with these hotfixes, since there's always a risk that fixing one bug introduces a new one, and we want the `stable` channel to always represent our most tested builds.
We intend to announce hotfixes to the [flutter-announce](https://groups.google.com/forum/#!forum/flutter-announce) group, and we recommend that you subscribe to that list if you publish an application using Flutter.
Note that we only hotfix the latest version -- if you see bugs on older versions of the `stable` channel, please consider moving to the latest `stable` channel version.
To ensure that you have the latest stable version with the hotfixes listed below, use the flutter tool at the command line as follows:
```
$ flutter channel stable
$ flutter upgrade
```
<!--
INTERNAL NOTE: PLEASE DON'T JUST PASTE ISSUE TITLES!
Make sure that the text here helps customers understand
whether they are likely to be affected by the issue,
without them needing to read each issue individually.
Our goal is to make the list easy for them to scan.
More information and tips:

# Code of conduct
The Flutter project expects Flutter's contributors to act professionally
and respectfully. Flutter contributors are expected to maintain the safety
and dignity of Flutter's social environments (such as GitHub and Discord).
Specifically:
* Respect people, their identities, their culture, and their work.
* Be kind. Be courteous. Be welcoming.
* Listen. Consider and acknowledge people's points before responding.
Should you experience anything that makes you feel unwelcome in Flutter's
community, please contact [conduct@flutter.dev](mailto:conduct@flutter.dev)
or, if you prefer, directly contact someone on the project, for instance
[Hixie](mailto:ian@hixie.ch).
The Flutter project will not tolerate harassment in Flutter's
community, even outside of Flutter's public communication channels.
## Conflict resolution
When multiple contributors disagree on the direction for a particular
patch or the general direction of the project, the conflict should be
resolved by communication. The people who disagree should get
together, try to understand each other's points of view, and work to
find a design that addresses everyone's concerns.
This is usually sufficient to resolve issues. If you cannot come to an
agreement, ask for the advice of a more senior member of the project.
Be wary of agreement by attrition, where one person argues a point
repeatedly until other participants give up in the interests of moving
on. This is not conflict resolution, as it does not address everyone's
concerns. Be wary of agreement by compromise, where two good competing
solutions are merged into one mediocre solution. A conflict is
addressed when the participants agree that the final solution is
_better_ than all the conflicting proposals. Sometimes the solution is
more work than either of the proposals. [Embrace the yak shave](./docs/contributing/Style-guide-for-Flutter-repo.md#lazy-programming).
## Questions
It's always ok to ask questions. Our systems are large, and nobody will be
an expert in all the systems. Once you find the answer, document it in
the first place you looked. That way, the next person will be brought
up to speed even quicker.
!["I try not to make fun of people for admitting they don't know things, because for each thing 'everyone knows' by the time they're adults, every day there are, on average, 10,000 people in the US hearing about it for the first time. If I make fun of people, I train them not to tell me when they have those moments. And I miss out on the fun." "Diet coke and mentos thing? What's that?" "Oh, man! We're going to the grocery store." "Why?" "You're one of today's lucky 10,000."](https://imgs.xkcd.com/comics/ten_thousand.png)

Contributing to Flutter
=======================
_tl;dr: join [Discord](./docs/contributing/Chat.md), be [courteous](CODE_OF_CONDUCT.md), follow the steps below to set up a development environment; if you stick around and contribute, you can [join the team](./docs/contributing/Contributor-access.md) and get commit access._
Welcome
-------
We invite you to join the Flutter team, which is made up of volunteers and sponsored folk alike!
There are many ways to contribute, including writing code, filing issues on GitHub, helping people
on our mailing lists, our chat channels, or on Stack Overflow, helping to triage, reproduce, or
fix bugs that people have filed, adding to our documentation,
doing outreach about Flutter, or helping out in any other way.
We grant commit access (which includes full rights to the issue
database, such as being able to edit labels) to people who have gained
our trust and demonstrated a commitment to Flutter. For more details
see the [Contributor access](./docs/contributing/Contributor-access.md)
page in our docs.
We communicate primarily over GitHub and [Discord](./docs/contributing/Chat.md).
Before you get started, we encourage you to read these documents which describe some of our community norms:
1. [Our code of conduct](CODE_OF_CONDUCT.md), which stipulates explicitly
that everyone must be gracious, respectful, and professional. This
also documents our conflict resolution policy and encourages people
to ask questions.
2. [Values](./docs/about/Values.md),
which talks about what we care most about.
Helping out in the issue database
---------------------------------
Triage is the process of going through bug reports and determining if they are valid, finding out
how to reproduce them, catching duplicate reports, and generally making our issues list
useful for our engineers.
If you want to help us triage, you are very welcome to do so!
1. Join the #hackers-triage [Discord channel](./docs/contributing/Chat.md).
2. Read [our code of conduct](CODE_OF_CONDUCT.md), which stipulates explicitly
that everyone must be gracious, respectful, and professional. If you're helping out
with triage, you are representing the Flutter team, and so you want to make sure to
make a good impression!
3. Help out as described in our [triage guide](./docs/triage/README.md)
You won't be able to add labels at first, so instead start by trying to
do the other steps, e.g. trying to reproduce the problem and asking for people to
provide enough details that you can reproduce the problem, pointing out duplicates,
and so on. Chat on the #hackers-triage channel to let us know what you're up to!
4. Familiarize yourself with our
[issue hygiene](./docs/contributing/issue_hygiene/README.md) wiki page,
which covers the meanings of some important GitHub labels and
milestones.
5. Once you've been doing this for a while, someone will invite you to the flutter-hackers
team on GitHub and you'll be able to add labels too. See the
[contributor access](./docs/contributing/Contributor-access.md) wiki
page for details.
Quality Assurance
-----------------
One of the most useful tasks, closely related to triage, is finding and filing bug reports. Testing
beta releases, looking for regressions, creating test cases, adding to our test suites, and
other work along these lines can really drive the quality of the product up. Creating tests
that increase our test coverage, writing tests for issues others have filed, all these tasks
are really valuable contributions to open source projects.
If this interests you, you can jump in and submit bug reports without needing anyone's permission!
The #quality-assurance channel on our [Discord server](./docs/contributing/Chat.md)
is a good place to talk about what you're doing. We're especially eager for QA testing when
we announce a beta release. See [quality assurance](./docs/releases/Quality-Assurance.md) for
more details.
If you want to contribute test cases, you can also submit PRs. See the next section
for how to set up your development environment, or ask in #hackers-test on Discord.
> As a personal side note, this is exactly the kind of work that first got me into open
> source. I was a Quality Assurance volunteer on the Mozilla project, writing test cases for
> browsers, long before I wrote a line of code for any open source project. —Hixie
Developing for Flutter
----------------------
If you prefer to write code, consider starting with the list of good
first issues for [Flutter][flutter-gfi] or for [Flutter DevTools][devtools-gfi].
Reference the respective sections below for further instructions.
[flutter-gfi]: https://github.com/flutter/flutter/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22
[devtools-gfi]: https://github.com/flutter/devtools/labels/good%20first%20issue
### Framework and Engine
To develop for Flutter, you will eventually need to become familiar
with our processes and conventions. This section lists the documents
that describe these methodologies. The following list is ordered: you
are strongly recommended to go through these documents in the order
presented.
1. [Setting up your engine development environment](./engine/src/flutter/docs/contributing/Setting-up-the-Engine-development-environment.md),
which describes the steps you need to configure your computer to
work on Flutter's engine. If you only want to write code for the
Flutter framework, you can skip this step. Flutter's engine mainly
uses C++, Java, and Objective-C.
2. [Setting up your framework development environment](./docs/contributing/Setting-up-the-Framework-development-environment.md),
which describes the steps you need to configure your computer to
work on Flutter's framework. Flutter's framework mainly uses Dart.
3. [Tree hygiene](./docs/contributing/Tree-hygiene.md),
which covers how to land a PR, how to do code review, how to
handle breaking changes, how to handle regressions, and how to
handle post-commit test failures.
4. [Our style guide](./docs/contributing/Style-guide-for-Flutter-repo.md),
which includes advice for designing APIs for Flutter, and how to
format code in the framework.
5. [Flutter design doc template](https://flutter.dev/go/template),
which should be used when proposing a new technical design. This is a good
practice to do before coding more intricate changes.
See also our [guidance for writing design docs](./docs/contributing/Design-Documents.md).
[![How to contribute to Flutter](https://img.youtube.com/vi/4yBgOBAOx_A/0.jpg)](https://www.youtube.com/watch?v=4yBgOBAOx_A)
In addition to the documents, there is a video linked above on **How to contribute to Flutter**
from the [Flutter](https://youtube.com/c/flutterdev) YouTube channel,
there are many pages in [our docs](./docs/README.md),
and an article [Contributing to Flutter: Getting Started](https://medium.com/@ayushbherwani/contributing-to-flutter-getting-started-a0db68cbcd5b)
on Medium that may be of interest. For a curated list of pages see the sidebar
on the wiki's home page. They are more or less listed in order of importance.
### DevTools
Contributing code to Dart & Flutter DevTools may be a good place to start if you are
looking to dip your toes into contributing with a relatively low-cost setup or if you
are generally excited about improving the Dart & Flutter developer experience.
Please see the DevTools [CONTRIBUTING.md](https://github.com/flutter/devtools/blob/master/CONTRIBUTING.md)
guide to get started.
### Helping with existing PRs
Once you've learned the process of contributing, if you aren't sure what to work on next you
might be interested in helping other developers complete their contributions by picking up an
incomplete patch from the list of [issues with partial patches][has-partial-patch].
[has-partial-patch]: https://github.com/flutter/flutter/labels/has%20partial%20patch
Outreach
--------
If your interests lie in the direction of developer relations and developer outreach,
whether advocating for Flutter, answering questions in fora like
[Stack Overflow](https://stackoverflow.com/questions/tagged/flutter?sort=Newest&filters=NoAnswers,NoAcceptedAnswer&edited=true)
or [Reddit](https://www.reddit.com/r/flutterhelp/new/?f=flair_name%3A%22OPEN%22),
or creating content for our [documentation](https://docs.flutter.dev/)
or sites like [YouTube](https://www.youtube.com/results?search_query=flutter&sp=EgQIAxAB),
the best starting point is to join the #hackers-devrel [Discord channel](./docs/contributing/Chat.md).
From there, you can describe what you're interested in doing, and go ahead and do it!
As others become familiar with your work, they may have feedback, be interested in
collaborating, or want to coordinate their efforts with yours.
API documentation
-----------------
Another great area to contribute in is sample code and API documentation. If this is an area that interests you, join our
[Discord](./docs/contributing/Chat.md) server and introduce yourself on the #hackers-devrel, #hackers-framework,
or #hackers-engine channels, describing your area of interest. As our API docs are integrated into our source code, see the
"developing for Flutter" section above for a guide on how to set up your developer environment.
To contribute API documentation, an excellent command of the English language is particularly helpful, as is a careful attention to detail.
We have a [whole section in our style guide](./docs/contributing/Style-guide-for-Flutter-repo.md#documentation-dartdocs-javadocs-etc)
that you should read before you write API documentation. It includes notes on the "Flutter Voice", such as our word and grammar conventions.
In general, a really productive way to improve documentation is to use Flutter and stop any time you have a question: find the answer, then
document the answer where you first looked for it.
We also keep [a list of areas that need better API documentation](https://github.com/flutter/flutter/issues?q=is%3Aopen+is%3Aissue+label%3A%22d%3A+api+docs%22+sort%3Areactions-%2B1-desc).
In many cases, we have written down what needs to be said in the relevant issue, we just haven't gotten around to doing it!
We're especially eager to add sample code and diagrams to our API documentation. Diagrams are generated from Flutter code that
draws to a canvas, and stored in a [special repository](https://github.com/flutter/assets-for-api-docs/#readme). It can be a lot of fun
to create new diagrams for the API docs.
Releases
--------
If you are interested in participating in our release process, which may involve writing release notes and blog posts, coordinating the actual
generation of binaries, updating our release tooling, and other work of that nature, then reach out on the #hackers-releases
channel of our [Discord](./docs/contributing/Chat.md) server.
Social events in the contributor community
------------------------------------------
Finally, one area where you could have a lot of impact is in contributing to social interactions among the Flutter contributor community itself.
This could take the form of organizing weekly video chats on our Discord, or planning tech talks from contributors, for example.
If this is an area that is of interest to you, please join our [Discord](./docs/contributing/Chat.md) and ping Hixie on the #hackers
channel!

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
* [Install Flutter](https://flutter.dev/get-started/)
* [Flutter documentation](https://docs.flutter.dev/)
* [Development wiki](./docs/README.md)
* [Contributing to Flutter](https://github.com/flutter/flutter/blob/main/CONTRIBUTING.md)
For announcements about new releases, follow the
[flutter-announce@googlegroups.com](https://groups.google.com/forum/#!forum/flutter-announce)
mailing list. Our documentation also tracks [breaking
changes](https://docs.flutter.dev/release/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][widget catalog] 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 hardware-accelerated 2D graphics
libraries like [Skia] (which underpins Chrome and Android) and
[Impeller]. 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,
JavaScript and WebAssembly for the web, as well as Intel x64 and ARM
for desktop devices.

### Productive development
Flutter offers [stateful hot reload][Hot reload], allowing you to make changes to your code
and see the results instantly without restarting your app or losing its state.
[![Hot reload animation][]][Hot reload]
### 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][Flutter packages] to speed your
development, regardless of your target platform. And accessing other native code
is easy, with support for both FFI ([on Android][Android FFI], [on iOS][iOS FFI],
[on macOS][macOS FFI], and [on Windows][Windows FFI]) as well as
[platform-specific APIs][platform channels].
Flutter is a fully open-source project, and we welcome contributions.

This directory contains tools and resources that the Flutter team uses
during the development of the framework. The tools in this directory
should not be necessary for developing Flutter applications, though of
course, they may be interesting if you are curious.
The tests in this directory are run in the `framework_tests_misc-*`

# a11y_assessments
This app is used for internal testing.
## Release a new version for Android
pre-requisite: This can and should only be done by a googler and you must also
be in the flutter.dev play console account.
1. Follow https://docs.flutter.dev/deployment/android to create a keystore file if you don't already
have one.
2. Bump the pubspec.yaml version
3. Create a key.properties file in `android/` directory following this format.
```
storePassword=<password>
keyPassword=<password>
keyAlias=upload
storeFile=<keystore path>
```
4. Run `flutter build appbundle` and upload the artifact to play console
## Release a new version for iOS
pre-requisite: This can and should only be done by a googler and you must also
be in the FLUTTER.IO LLC developer account with iOS distribution permission.
1. Bump the pubspec.yaml version
2. Run `flutter build ipa` and upload the artifact to app store using transporter or other tools.
For more information, see https://docs.flutter.dev/deployment/ios.
3. Once the app is in TestFlight, add appropriate testers to the app so they can start testing.

# Launch Screen Assets
You can customize the launch screen with your own desired assets by replacing the image files in this directory.
You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
