# microbenchmarks
To run these benchmarks on a device, first run `flutter logs' in one
window to see the device logs, then, in a different window, run any of
these:
```
flutter run --release lib/gestures/velocity_tracker_bench.dart
flutter run --release lib/gestures/gesture_detector_bench.dart
flutter run --release lib/stocks/animation_bench.dart
flutter run --release lib/stocks/build_bench.dart
flutter run --release lib/stocks/layout_bench.dart
```
The results should be in the device logs.
### Avoid changing names of the benchmarks
Each microbenchmark is identified by a name, for example,
"catmullrom_transform_iteration". Changing the name of an existing
microbenchmarks will effectively remove the old benchmark and create a new one,
losing the historical data associated with the old benchmark in the process.

# Flutter's Build Infrastructure
This directory exists to support building Flutter on our build infrastructure.
Flutter build results are available at:
* https://flutter-dashboard.appspot.com/#/build
- Aggregate dashboard of the separate CI systems used by Flutter.
* https://cirrus-ci.com/github/flutter/flutter/master
- Testing is done on PRs and submitted changes on GitHub.
Flutter infra requires special permissions to retrigger builds on the
[build dashboard](https://flutter-dashboard.appspot.com/#/build). File an
[infra ticket](https://github.com/flutter/flutter/wiki/Infra-Ticket-Queue) to
request permission.
The [Cirrus](https://cirrus-ci.org)-based bots run the [`test.dart`](test.dart)
script for each PR and submission. This does testing for the tools, for the
framework, and (for submitted changes only) rebuilds and updates the main
branch API docs [staging site](https://main-api.flutter.dev/).
For tagged dev and beta builds, it also builds and deploys the gallery app to
the app stores. It is configured by the [.cirrus.yml](/.cirrus.yml).
The build dashboard includes post-commit testing run on physical devices. See
[//dev/devicelab](../devicelab/README.md) for more information.
## LUCI (Layered Universal Continuous Integration)
A [set of infra scripts](https://flutter.googlesource.com/recipes/)
run on Windows, Linux, and Mac machines. The configuration for how many
machines and what kind are managed internally by Google. File an
[infra ticket](https://github.com/flutter/flutter/wiki/Infra-Ticket-Queue)
to request new machine types to be added. Both of these technologies are highly
specific to the [LUCI](https://github.com/luci) project, which is the successor
to Chromium's infra and the foundation to Flutter's infrastructure.
### Prerequisites
To work on this infrastructure you will need:
- [depot_tools](https://commondatastorage.googleapis.com/chrome-infra-docs/flat/depot_tools/docs/html/depot_tools_tutorial.html#_setting_up)
- Python package installer: `sudo apt-get install python-pip`
- Python coverage package (only needed for `training_simulation`): `sudo pip install coverage`
To run `prepare_package.dart` locally:
- Make sure the `depot_tools` is in your `PATH`. If you're on Windows, you also need
an environment variable called `DEPOT_TOOLS` with the path to `depot_tools` as value.
- Run `gsutil.py config` (or `python3 %DEPOT_TOOLS%\gsutil.py` on Windows) to
authenticate with your auth token.
- Create a local temp directory. `cd` into it.
- Run `dart [path to your normal Flutter repo]/dev/bots/prepare_package.dart
--temp_dir=. --revision=[revision to package] --branch=[branch to deploy to]
--publish`.
- If you're running into `gsutil` permission issues, check with @Hixie to make sure
you have the right push permissions.
### Editing a recipe
Flutter has several recipes depending on the test. The recipes share common
actions through `recipe_modules`. Searching the builder config in [infra](https://flutter.googlesource.com/infra/+/refs/heads/main)
will indicate the recipe used for a test.
Recipes are just Python with some limitations on what can be imported. They are
[documented](https://github.com/luci/recipes-py/blob/master/doc/user_guide.md)
by the [luci/recipes-py GitHub project](https://github.com/luci/recipes-py).
The typical cycle for editing a recipe is:
1. Check out the recipes project using `git clone https://flutter.googlesource.com/recipes`.
2. Make your edits (probably to files in
`//recipes/recipes`).
3. Update the tests. Run `recipes.py test train` to update
the existing expected output to match the new output. Verify completely new test
cases by altering the `GenTests` method of the recipe. The recipe is required
to have 100% test coverage.
4. Run `led get-builder 'luci.flutter.staging:BUILDER_NAME' | led edit -pa git_ref='refs/pull/<PR number>/head' | led edit -pa git_url='https://github.com/flutter/<repo>' | led edit-recipe-bundle | led launch`, where `BUILDER_NAME` is the builder name (e.g. `Linux Engine`), and
`git_ref`/`git_url` is the ref/url of the intended changes to build.
* If `led` fails, ensure that your `depot_tools` checkout is up to date.
5. To submit a CL, you need a local branch first (`git checkout -b [some branch name]`).
6. Upload the patch (`git commit`, `git cl upload`), and open the outputted URL to the CL.
7. Use "Find owners" to get reviewers for the CL
### Android Tools
The Android SDK and NDK used by Flutter's Chrome infra bots are stored in Google
Cloud. During the build, a bot runs the `download_android_tools.py` script that
downloads the required version of the Android SDK into `dev/bots/android_tools`.
To check which components are currently installed, download the current SDK
stored in Google Cloud using the `download_android_tools.py` script, then
`dev/bots/android_tools/sdk/tools/bin/sdkmanager --list`. If you find that some
components need to be updated or installed, follow the steps below:
#### How to update Android SDK on Google Cloud Storage
1. Run Android SDK Manager and update packages
`$ dev/bots/android_tools/sdk/tools/android update sdk`
Use `android.bat` on Windows.
2. Use the UI to choose the packages you want to install and/or update.
3. Run `dev/bots/android_tools/sdk/tools/bin/sdkmanager --update`. On Windows,
run `sdkmanager.bat` instead. If the process fails with an error saying that
it is unable to move files (Windows makes files and directories read-only
when another process is holding them open), make a copy of the
`dev/bots/android_tools/sdk/tools` directory, run the `sdkmanager.bat` from
the copy, and use the `--sdk_root` option pointing at
`dev/bots/android_tools/sdk`.
4. Run `dev/bots/android_tools/sdk/tools/bin/sdkmanager --licenses` and accept
the licenses for the newly installed components. It also helps to run this
command a second time and make sure that it prints "All SDK package licenses
accepted".
5. Run upload_android_tools.py -t sdk
`$ dev/bots/upload_android_tools.py -t sdk`
#### How to update Android NDK on Google Cloud Storage
1. Download a new NDK binary (e.g. android-ndk-r10e-linux-x86_64.bin)
2. cd dev/bots/android_tools
`$ cd dev/bots/android_tools`
3. Remove the old ndk directory
`$ rm -rf ndk`
4. Run the new NDK binary file
`$ ./android-ndk-r10e-linux-x86_64.bin`
5. Rename the extracted directory to ndk
`$ mv android-ndk-r10e ndk`
6. Run upload_android_tools.py -t ndk
`$ cd ../..`
`$ dev/bots/upload_android_tools.py -t ndk`
## Flutter codelabs build test
The Flutter codelabs exercise Material Components in the form of a
demo application. The code for the codelabs is similar to, but
distinct from, the code for the Shrine demo app in Flutter Gallery.
The Flutter codelabs build test ensures that the final version of the
[Material Components for Flutter
Codelabs](https://github.com/material-components/material-components-flutter-codelabs)
can be built. This test serves as a smoke test for the Flutter
framework and should not fail. If it does, please address any issues
in your PR and rerun the test. If you feel that the test failing is
not a direct result of changes made in your PR or that breaking this
test is absolutely necessary, escalate this issue by [submitting an
issue](https://github.com/material-components/material-components-flutter-codelabs/issues/new?title=%5BURGENT%5D%20Flutter%20Framework%20breaking%20PR)
to the MDC-Flutter Team.
## Unpublishing published archives
Flutter downloadable archives are built for each release by our continuous
integration systems using the [`prepare_package.dart`](prepare_package.dart)
script, but if something goes very wrong, and a release is published that wasn't
intended to be published, the [`unpublish_package.dart`](unpublish_package.dart)
script may be used to remove the package or packages from the channels in which
they were published.
For example To remove a published package corresponding to the git hash
`d444a455de87a2e40b7f576dc12ffd9ab82fd491`, first do a dry run of the script to
see what it will do:
```
$ dart ./unpublish_package.dart --temp_dir=/tmp/foo --revision d444a455de87a2e40b7f576dc12ffd9ab82fd491
```
And once you've verified the output of the dry run to be sure it is what you
want to do, run:
```
$ dart ./unpublish_package.dart --confirm --temp_dir=/tmp/foo --revision d444a455de87a2e40b7f576dc12ffd9ab82fd491
```
and it will perform the actions. You will of course need to have access
to the cloud storage server and have `gsutil` installed to perform this
operation. Only runs on Linux or macOS systems.
See `dart ./unpublish_package.dart --help` for more details.
Once the package is unpublished, it will not be available from the website for
download, and will not be rebuilt (even though there is a tagged revision in the
repo still) unless someone forces the packaging build to run again at that
revision to rebuild the package.

# Fortnightly
A Flutter sample app based on the Material study Fortnightly (a hypothetical, online newspaper.) It
showcases print-quality, custom typography, Material Theming, and text-heavy UI design and layout.
For info on the Fortnightly Material Study, see: https://material.io/design/material-studies/fortnightly.html
## Goals for this sample
* Help you understand how to customize and layout text.
* Provide you with example code for
* Text
* A short app bar (the menu button top left.)
* Avatar images
## Widgets / APIs
* BeveledRectangleBorder
* BoxConstraints on Container
* CircleAvatar
* ExactAssetImage
* Fonts
* SafeArea
* Stack
* SingleChildScrollView
* Text
* TextStyle
* TextTheme
## Notice
* Theming is passed as a parameter in the constructor of `MaterialApp` (`theme:`).
* `SafeArea` adds padding around notches and virtual home buttons on screens that have them (like
iPhone X+). Here, it protects the `ShortAppBar` from overlapping with the status bar (time)
and makes sure the bottom of the newspaper article has padding beneath it if necessary.
* The entire newspaper article is wrapped in a `SingleChildScrollView` widget which ensures that the
entire article can be viewed no matter what the screen's size or orientation is.
* The `Text` widget with text ' ¬ ' has a `TextStyle` that changes one parameter of an inherited
`TextStyle` using `.apply()``.
* The `Text` widget with text 'Connor Eghan' has a `TextStyle` created explicitly instead of
inheriting from theming.
* You can break up long strings in your source files by putting them on multiple lines.
* Fonts are imported with multiple files expressing their weights (Bold, Light, Medium, Regular)
but are accessed with a `FontWeight` value like `FontWeight.w800` for Merriweather-Bold.ttf.
## Questions/issues
If you have a general question about developing in Flutter, the best places to go are:
* [The FlutterDev Google Group](https://groups.google.com/forum/#!forum/flutter-dev)
* [The Flutter Gitter channel](https://gitter.im/flutter/flutter)
* [StackOverflow](https://stackoverflow.com/questions/tagged/flutter)
