## Developing for DevTools
### Set up your DevTools environment
**Before setting up your DevTools environment**, please make sure you have
[cloned the Flutter SDK from GitHub](https://docs.flutter.dev/get-started/install/macos#downloading-straight-from-github-instead-of-using-an-archive)
and added the included `flutter` and `dart` executables to your `PATH` environment variable (see Flutter
instructions for how to [update your PATH](https://docs.flutter.dev/get-started/install/macos#update-your-path)).
Typing `which flutter` and `which dart` (or `where.exe flutter` and `where.exe dart` for Windows)
into your terminal should print the path to the binaries from Flutter SDK you cloned from Github.
1. [Fork](https://docs.github.com/en/get-started/quickstart/fork-a-repo) the DevTools repo to your
own Github account, and then clone it using SSH. If you haven't already, you may need to
[generate a new SSH key](https://docs.github.com/en/github/authenticating-to-github/connecting-to-github-with-ssh)
to connect to Github with SSH.
2. Make sure to [configure Git to keep your fork in sync](https://docs.github.com/en/get-started/quickstart/fork-a-repo#configuring-git-to-sync-your-fork-with-the-upstream-repository)
with the upstream DevTools repo.
3. Ensure that you have access to the `devtools_tool` executable by:
- Running `flutter pub get` on the `devtools/tool` directory
- Adding the `devtools/tool/bin` folder to your `PATH` environment variable:
- **MacOS Users**
- add the following to your `~/.zshrc` file (or `~/.bashrc`, `~/.bash_profile` if you use Bash),
replacing `<DEVTOOLS_DIR>` with the local path to your DevTools repo:
```
export PATH=$PATH:<DEVTOOLS_DIR>/tool/bin
```
- **Windows Users**
- Open "Edit environment variables for your account" from Control Panel
- Locate the `Path` variable and click **Edit**
- Click the **New** button and paste in `<DEVTOOLS_DIR>/tool/bin`, replacing `<DEVTOOLS_DIR>`
with the local path to your DevTools repo.
Explore the commands and helpers that the `devtools_tool` provides by running `devtools_tool -h`.
4. **Optional:** enable and activate DCM (Dart Code Metrics) - see the [DCM section below](#enable-and-activate-dcm-dart-code-metrics)
#### Set up your IDE
We recommend using VS Code for your DevTools development environment because this gives you
access to some advanced development and configuration features. When you open DevTools in VS Code,
open the `devtools/packages` directory in your VS Code workspace. This will give you access to a set
of launch configurations for running and debugging DevTools:
### Workflow for making changes
1. Change your local Flutter SDK to the latest flutter candidate branch: `devtools_tool update-flutter-sdk --from-path`
2. Create a branch from your cloned DevTools repo: `git checkout -b myBranch`
3. Ensure your branch, dependencies, and generated code are up-to-date: `devtools_tool sync`
4. Implement your changes, and commit to your branch: `git commit -m “description”`
- If your improvement is user-facing, document it in [NEXT_RELEASE_NOTES.md](packages/devtools_app/release_notes/NEXT_RELEASE_NOTES.md)
and include this edit as part of your PR.
5. Push to your branch to GitHub: `git push origin myBranch`
6. Navigate to the [Pull Requests](https://github.com/flutter/devtools/pulls) tab in the main
[DevTools repo](https://github.com/flutter/devtools). You should see a popup to create a pull
request from the branch in your cloned repo to the DevTools master branch. Create a pull request.
- **Running the Dart Code Metrics Github workflow:** any PRs that change Dart code require the
Dart Code Metrics workflow to be run before being submitted. To trigger the workflow, add the
label `run-dcm-workflow` to your PR. If you don't have permission to add the label, your
reviewer can add it for you.
- Any DCM errors will be caught by the workflow. Fix them and push up your changes. To trigger
the DCM workflow to run again, you will need to remove and then re-add the `run-dcm-workflow` label.
### Keeping your fork in-sync
- If at any time you need to re-sync your branch, run:
```
devtools_tool sync
```
This will pull the latest code from the upstream DevTools, upgrade dependencies, and perform code generation.
- If you want to upgrade dependencies and re-generate code (like mocks), but do not want to merge `upstream/master`, instead run
```
devtools_tool generate-code --upgrade
```
- To update DCM to the same version as on GitHub bots with apt-get or brew:
1. Locate, copy and run apt-get command searching by searching for `install dcm` in [build.yaml](https://github.com/flutter/devtools/blob/master/.github/workflows/build.yaml)
2. Locate version on bots by searching for `install dcm` in [build.yaml](https://github.com/flutter/devtools/blob/master/.github/workflows/build.yaml) and run `brew install cqlabs/dcm/dcm@<version on bots without -1>`
You can check you current local version with `dcm --version`.
If version of DCM on bots is outdated, consider to submit a PR to refresh the version on bots.
## Running and debugging DevTools
There are a few different environments that you may need to run DevTools in. After running DevTools
in one of the environments below, connect to a test application to debug DevTools runtime tooling
(the majority of DevTools tools). See the
[Connect DevTools to a test application](#connect-devtools-to-a-test-application) section below.
### Frontend only (most common)
Most of the time, you will not need to run DevTools with the DevTools server to test your changes.
You can run DevTools in debug mode as either a Flutter web or Flutter desktop app.
> Note: though DevTools is shipped as a Flutter Web app, we recommend developing as a Flutter
Desktop app whenever possible for a more efficient development workflow. Please see the
[running on Flutter desktop](#running-devtools-on-flutter-desktop) section below for instructions.
- To run DevTools as a Flutter web app **from VS Code**, run with the **devtools (packages)** configuration and the "Chrome" device
- To run with experiments enabled, run from VS Code with the **devtools + experiments (packages)** configuration
- To run DevTools as a Flutter web app **from the command line**, run `flutter run -d chrome`
- To run with experiments enabled, add the flag `--dart-define=enable_experiments=true`
### Frontend + DevTools server
To develop with a workflow that exercises the DevTools server <==> DevTools client connection,
you will need to perform the following set up steps (first time only).
1. Clone the [Dart SDK](https://github.com/dart-lang/sdk) fron GitHub.
2. The `LOCAL_DART_SDK` environment variable needs to point to this path: `export LOCAL_DART_SDK=/path/to/dart/sdk`
If you are also developing server side code (e.g. the `devtools_shared` package), you will need to add a
dependency override to `sdk/pkg/dds/pubspec.yaml`.
```yaml
dependency_overrides:
devtools_shared:
path: relative/path/to/devtools/packages/devtools_shared
```
Then you can run DevTools with the server by running the following from the top-level `devtools` directory:
```
devtools_tool serve
```
### DevTools + VS Code integration (IDE-embedded DevTools experience)
To test the integration with VS Code, you can set up the Dart VS Code extension to run DevTools
and the server from your local source code. Follow the
[Frontend + DevTools server](#frontend--devtools-server) setup instructions above, and make sure
you have version v3.47 or newer of the Dart extension for VS Code.
Open your VS Code settings (Run the **Preferences: Open User Settings (JSON)** command from the
command palette (`F1`)) and add the following to your settings:
```js
"dart.customDevTools": {
"path": "/path/to/devtools",
"env": {
"LOCAL_DART_SDK": "/path/to/sdk"
// Path to the version that Flutter DevTools is pinned to.
"FLUTTER_ROOT": "/path/to/devtools/tool/flutter-sdk"
}
},
```
This instructs VS Code to run the `devtools_tool serve` command instead of running `dart devtools`.
You must set the `LOCAL_DART_SDK` and `FLUTTER_ROOT` env variables correctly for the script to work.
Next, restart VS Code (or run the **Developer: Reload Window** command from the command palette (`F1`))
and DevTools will be run from your local source code. After making any code changes to DevTools or the
server, you will need to re-run the **Developer: Reload Window** command to rebuild and restart the server.
## Testing for DevTools
Please see [TESTING.md](TESTING.md) for guidance on running and writing tests.
## Appendix
### Connect DevTools to a test application
For working on most DevTools tools, a connection to a running Dart or Flutter app is required. Run any Dart of Flutter app of your choice to
connect it to DevTools. Consider running the [Flutter gallery](https://github.com/flutter/gallery#running) app, as it has plenty of interesting
code to debug.
1. Run your Dart or Flutter app
> Note: some DevTools features may be unavailable depending on the test app platform (Flutter native, Flutter web, Dart CLI, etc.) or run mode
(debug, profile) you choose.
2. Copy the URI printed to the command line (you will use this uri to connect to DevTools)
```
"A Dart VM Service on iPhone 14 Pro Max is available at: <copy-this-uri>"
```
3. Paste this URI into the connect dialog in DevTools and click "Connect"
### Running DevTools on Flutter Desktop
For a faster development cycle with hot reload, you can run DevTools on Flutter desktop. Some DevTools
features only work on the web, like the embedded Perfetto trace viewer, DevTools extensions, or DevTools
analytics, but the limitations on the desktop app are few.
To run DevTools with the desktop embedder, you can run with either of the following from `devtools/packages/devtools_app`:
- `flutter run -d macos`
- `flutter run -d linux`
If this fails, you may need to run `flutter create .` from `devtools/packages/devtools_app` to generate
the updated files for your platform. If you want to run DevTools on Flutter desktop for Windows, you will
need to generate the files for this platform using the same command, and then run using `flutter run -d windows`.
### Enable and activate DCM (Dart Code Metrics)
Enabling and activating DCM is optional. When you open a PR, the CI bots will show you any DCM warnings introduced
by your change which should be fixed before submitting.
- **Contributors who work at Google:** you can use the Google-purchased license key to activate DCM.
See [go/dash-devexp-dcm-keys](http://goto.google.com/dash-devexp-dcm-keys).
- **All other contributors:** please follow instructions at <https://dcm.dev/pricing/>. You can either use the free tier of DCM, or purchase a team license. Note that the free tier doesn't support all the rules of the paid tier, so you will also need to consult the output of the [Dart Code Metrics workflow on Github](#running-the-dart-code-metrics-github-workflow) when you open your PR.
To enable DCM:
1. Install the executable for your target platform. You can refer to [this guide](https://dcm.dev/docs/teams/getting-started/#installation).
2. [Get the license key](http://goto.google.com/dash-devexp-dcm-keys) and activate DCM. To do so, run `dcm activate --license-key=YOUR_KEY` from the console.
3. Install the extension for your IDE. If you use VS Code, you can get it from [the marketplace](https://marketplace.visualstudio.com/items?itemName=dcmdev.dcm-vscode-extension). If you use IntelliJ IDEA or Android Studio, you can find the plugin [here](https://plugins.jetbrains.com/plugin/20856-dcm).
4. Reload the IDE.
>Note: DCM issues can be distinguished from the Dart analyzer issues by their name: DCM rule names contain `-`. Some of the issues can be fixed via CLI, to do so, run `dcm fix` for any directory. To apply `dcm fix` on a file save in the IDE, refer to [this guide](https://dcm.dev/docs/teams/ide-integrations/vscode/#extension-capabilities).
### third_party dependencies
All content not authored by the Flutter team (which includes both sponsored and open-source contributors)
must go in the `third_party` directory. As an expedient to make the `third_party` code work well with our
build scripts, code in `third_party` should be given a stub `pubspec.yaml` file so that you can reference
the resources from the packages directory from `packages/devtools_app/web/index.html`

## How to use Chrome DevTools for performance profiling
The Flutter framework emits timeline events as it works to build frames, draw
scenes, and track other activity such as garbage collections. These events are
exposed in the Chrome DevTools performance panel for debugging.
You can also emit your own timeline events using the `dart:developer`
[Timeline]($timelineLink) and [TimelineTask]($timelineTaskLink) APIs for further
performance analysis.
### Optional flags to enhance tracing
- [debugProfileBuildsEnabled]($debugBuildsLink): Adds Timeline events for every Widget built.
- [debugProfileBuildsEnabledUserWidgets]($debugUserBuildsLink): Adds Timeline events for every user-created Widget built.
- [debugProfileLayoutsEnabled]($debugLayoutsLink): Adds Timeline events for every RenderObject layout.
- [debugProfilePaintsEnabled]($debugPaintsLink): Adds Timeline events for every RenderObject painted.
### Instructions
1. *[Optional]* Set any desired tracing flags to true from your app's main method.
2. Run your Flutter web app in [profile mode]($profileModeLink).
3. Open up the [Chrome DevTools' Performance panel]($performancePanelLink) for
your application, and start recording to capture timeline events.

[TimelineTask]($timelineTaskLink) APIs are exposed in the Chrome DevTools
performance panel.
Open up the [Chrome DevTools' Performance panel]($performancePanelLink) for
your application, and start recording to capture timeline events.

# TODO(flutter/flutter#85356): This file was originally generated by the

# copied to the flutter repo to support `dart_library` targets used for
# Flutter-Fuchsia integration tests. This file can be maintained by hand, but it
# would be better to implement a script for Flutter, to either generate these
# BUILD.gn files or dynamically generate the GN targets.

// The Metal and OpenGL complexity calculators use benchmark data gathered
// using the display_list_benchmarks test suite on real devices.
//
// Constants of proportionality and trends were chosen to better match
// larger numbers rather than smaller ones. This may turn out to be the
// wrong decision, but the rationale here is that with the smaller numbers,
// we have:
//
// a) More noise.
// b) Less absolute difference. If the constant we've chosen is out by 50%
// on a measurement that is 0.001ms, that's less of an issue than if
// the measurement is 15ms.
// c) Smaller numbers affect the caching decision negligibly; the caching
// decision is likely to be driven by slower ops rather than faster ones.
//
// In some cases, a cost penalty is used to figure out the cost of an
// attribute such as anti-aliasing or fill style. In some of these, the
// penalty is proportional to some other value such as the radius of
// a circle. In these cases, we ensure that the penalty is never smaller
// than 1.0f.
//
// The error bars in measurement are likely quite large and will
// vary from device to device, so the goal here is not to provide a
// perfectly accurate representation of a given DisplayList's
// complexity but rather a very rough estimate that improves upon our
// previous cache admission policy (op_count > 5).
//
// There will likely be future work that will improve upon the figures
// in here. Notably, we do not take matrices or clips into account yet.
//
// The scoring is based around a baseline score of 100 being roughly
// equivalent to 0.0005ms of time. With a 32-bit unsigned integer, this
// would set the maximum time estimate associated with the complexity score
// at about 21 seconds, which far exceeds what we would ever expect a
// DisplayList to take rasterising.
//
// Finally, care has been taken to keep the computations as cheap as possible.
// We need to be able to calculate the complexity as quickly as possible
// so that we don't end up wasting too much time figuring out if something
// should be cached or not and eat into the time we could have just spent
// rasterising the DisplayList.
//
// In order to keep the computations cheap, the following tradeoffs were made:
//
// a) Limit all computations to simple division, multiplication, addition
// and subtraction.
// b) Try and use integer arithmetic as much as possible.
// c) If a specific draw op is logarithmic in complexity, do a best fit
// onto a linear equation within the range we expect to see the variables
// fall within.
//
// As an example of the above, let's say we have some data that looks like the
// complexity is something like O(n^1/3). We would like to avoid anything too
// expensive to calculate, so taking the cube root of the value to try and
// calculate the time cost should be avoided.
//
// In this case, the approach would be to take a straight line approximation
// that maps closely in the range of n where we feel it is most likely to occur.
// For example, if this were drawLine, and n were the line length, and we
// expected the line lengths to typically be between 50 and 100, then we would
// figure out the equation of the straight line graph that approximates the
// n^1/3 curve, and if possible try and choose an approximation that is more
// representative in the range of [50, 100] for n.
//
// Once that's done, we can develop the formula as follows:
//
// Take y = mx + c (straight line graph chosen as per guidelines above).
// Divide by however many ops the benchmark ran for a single pass.
// Multiply by 200,000 to normalise 0.0005ms = 100.
// Simplify down the formula.
//
// So if we had m = 1/5 and c = 0, and the drawLines benchmark ran 10,000
// drawLine calls per iteration:
//
// y (time taken) = x (line length) / 5
// y = x / 5 * 200,000 / 10,000
// y = x / 5 * 20
// y = 4x
