# platform_channels_benchmarks
The harness for running performance benchmark tests for Platform Channels.
If you want to run these benchmarks outside of devicelab you need to first run:
`flutter create --platforms="ios,android" --no-overwrite .`

# Flutter Conductor
Command-line tool for managing a release of the Flutter SDK. Also see
https://github.com/flutter/flutter/wiki/Release-process for more information on
the release process.
## Requirements
Some basic requirements to conduct a release are:
- a Linux or macOS computer set up for Flutter development. The conductor does
not support Windows.
- git
- Mirrors on GitHub of the Flutter
[framework](https://github.com/flutter/flutter) and
[engine](https://github.com/flutter/engine) repositories.
For the best experience, it is recommended to use ssh protocol for connecting to
GitHub remote repositories (i.e. for `--framework-mirror` and `--engine-mirror`
specify the remote with the format `[email protected]:username/reponame`). If your
local ssh key is password-protected, it is recommended to use ssh-agent to
unlock your ssh key for the session; if you do not, each time the conductor
attempts to interact with a remote, the user will be prompted to enter their ssh
key password.
## Usage
The main entrypoint for the conductor is [bin/conductor](bin/conductor). For
brevity, the rest of this document will assume that this entrypoint is on the
shell path.
All available commands can be seen via:
`conductor help`
Releases are initialized with the `start` sub-command, like:
```
conductor start \
--candidate-branch=flutter-2.2-candidate.10 \
--release-channel=beta \
--github-username=kingOfDevelopers \
--engine-cherrypicks=72114dafe28c8700f1d5d629c6ae9d34172ba395 \
--framework-cherrypicks=a3e66b396746f6581b2b7efd1b0d0f0074215128,d8d853436206e86f416236b930e97779b143a100 \
--dart-revision=4511eb2a779a612d9d6b2012123575013e0aef12 \
```
The conductor will, based on the release channel and the presence/lack of
previous tags, determine which part of the release version should be
incremented. In the cases where this is not correct, the version can be
overridden with `--version-override=3.0.0`.
For more details on these command line arguments, see `conductor help start`.
This command will write to disk a state file that will persist until the release
is completed. If you already have a persistent state file, this command will
fail with an error message. To see the current status of the release (at any
time), issue the command:
`conductor status`
To delete a persistent state file (either because the release was successfully
completed or abandoned), use the command:
`conductor clean`
Once initializing the release, the conductor tool will issue instructions for
manual steps that must be executed by the user. At any time these instructions
can be seen via `conductor status`. Once these manual steps have been completed,
you can proceed to the next step by using the command:
`conductor next`
## Steps
Once the user has finished manual steps for each step, they proceed to the next
step with the command:
`conductor next`
### Apply Engine Cherrypicks
The tool will attempt to auto-apply all engine cherrypicks. However, any
cherrypicks that result in a merge conflict will be reverted and it is left to
the user to manually cherry-pick them (with the command `git cherry-pick
$REVISION`) and resolve the merge conflict in their checkout.
Once a PR is opened, the user must validate CI builds. If there are regressions
(or if the `licenses_check` fails, then
`//engine/ci/licenses_golden/licenses_third_party` must be updated to match the
output of the failing test), then the user must fix these tests in their local
checkout and push their changes again.
### Apply Framework Cherrypicks
The tool will attempt to auto-apply all framework cherrypicks. However, any
cherrypicks that result in a merge conflict will be reverted and it is left to
the user to manually cherry-pick them (with the command `git cherry-pick
$REVISION`) and resolve the merge conflict in their checkout.
### Publish Version
This step will add a version git tag to the final Framework commit and push it
to the upstream repository. The presence of a tag affects what the flutter CLI
tool reports the current version is.
### Publish Channel
This step will push the Framework candidate branch to the upstream release
branch (e.g. the `stable` branch). Once this push happens upstream, the release
has officially been published, and the code will be available to existing
Flutter users via `flutter upgrade`.
### Verify Release
For the final step, the user must manually verify that packaging builds have
finished successfully. The SDK compressed archives will not be available from
the website until the packaging build has finished. The conductor will produce
links to the dashboards for monitoring CI builds.

# Forbidden from release tests
This program compiles the Dart portions of a Flutter application to the
AOT format used for release builds, and verifies that debugging related types
are not retained. By default, it uses the `//examples/hello_world` application
in this repository.
This harness is invoked from `dev/bots/test.dart`. By default it uses the
`examples/hello_world.dart` as if it were being compiled for Android arm64
release. New forbidden types may be added by adding more `--forbidden-type`
options in the `runForbiddenFromReleaseTests` method in `dev/bots/test.dart`

# external_textures
Tests external texture rendering between a native[^1] platform and Flutter.
Part of Flutter's API for [plugins](https://flutter.dev/docs/development/packages-and-plugins/developing-packages#plugin) includes passing _external textures_, or textures
created outside of Flutter, to Flutter, typically using the [`Texture`][texture]
widget. This is useful for plugins that render video, or for plugins that
interact with the camera.
For example:
- [`packages/camera`][camera]
- [`packages/video_player`][video_player]
[texture]: https://api.flutter.dev/flutter/widgets/Texture-class.html
[camera]: https://github.com/flutter/packages/tree/8255fbed74465425a1ec06a1804225e705e29f52/packages/camera
[video_player]: https://github.com/flutter/packages/tree/8255fbed74465425a1ec06a1804225e705e29f52/packages/video_player
Because external textures are created outside of Flutter, there is often subtle
translation that needs to happen between the native platform and Flutter, which
is hard to observe. These integration tests are designed to help catch these
subtle translation issues.
## How it works
- Each `lib/*_main.dart` file is a Flutter app instrumenting a test case.
- There is a corresponding `test_driver/*_test.dart` that runs assertions.
To run the test cases locally, use `flutter drive`[^2]:
```shell
flutter drive lib/frame_rate_main.dart --driver test_driver/frame_rate_test.dart
```
> [!TIP]
> On CI, the test cases are run within our [device lab](../../devicelab/README.md).
>
> See [`devicelab/lib/tasks/integration_tests.dart`](../../devicelab/lib/tasks/integration_tests.dart)
> and search for `createExternalUiFrameRateIntegrationTest`.
>
> The actual tests are run by task runners:
>
> - [Android](../../devicelab/bin/tasks/external_textures_integration_test.dart)
> - [iOS](../../devicelab/bin/tasks/external_textures_integration_test_ios.dart)
[^1]: Only iOS and Android.
[^2]: Unfortunately documentation is quite limited. See [#142021](https://github.com/flutter/flutter/issues/142021).

# Tracing tests
## "Application"
The `lib/test.dart` and `lib/control.dart` files in this directory are
used by `dev/bots/test.dart`'s `runTracingTests` function to check
whether aspects of the tracing logic in the framework get compiled out
in profile and release builds. They're not meant to be run directly.
The strings in these files are used in `dev/bots/test.dart`.
## Tests
The tests in this folder must be run with `flutter test --enable-vmservice`,
since they test that trace data is written to the timeline by connecting to
the observatory.
These tests will fail if run without this flag.
