This sorts the wiki pages owned by the Engine team in the docs/ directory as planned in [flutter.dev/go/migrate-flutter-wiki-spreadsheet](https://docs.google.com/spreadsheets/d/1x65189ZBdNiLRygpUYoU08pwvXD4M-Z157c6pm8deGI/edit?usp=sharing) It also adds the engine and team-engine labels to the bot for future PRs. Changes to the content were only updating cross links. The remaining wiki links will be updated after the rest of the pages are relocated, the original wiki links still work in the meantime.

## Treemaps
|
|
|
|
For each commit to [flutter/engine](https://github.com/flutter/engine) the Chromebots generate treemaps illustrating the sizes of the individual components within release builds of `libflutter.so`. The treemap is uploaded to Google Cloud Storage and linked from the [LUCI](https://ci.chromium.org/p/flutter/g/engine/console) console: Select a "Linux aot" build and search for "Open Treemap".
|
|
|
|
Alternatively, a link to a treemap can be constructed as follows:
|
|
|
|
`https://storage.googleapis.com/flutter_infra_release/flutter/<REVISION>/<VARIANT>/sizes/index.html` where:
|
|
* `<REVISION>` is the git hash from [flutter/engine](https://github.com/flutter/engine) for which you want the treemap, and
|
|
* `<VARIANT>` can be any android release build, e.g. `android-arm-release` or `android-arm64-release`.

## Benchmarks
|
|
|
|
In [devicelab](https://github.com/flutter/flutter/tree/main/dev/devicelab) we run various benchmarks to track the APK/IPA sizes and various (engine) artifacts contained within. These benchmarks run for every commit to [flutter/flutter](https://github.com/flutter/flutter) and are visible on our [build dashboard](https://flutter-dashboard.appspot.com/). The most relevant benchmarks for engine size are:
|
|
|
|
* APK/IPA size of Flutter Gallery
|
|
* Android: `flutter_gallery_android__compile/release_size_bytes`
|
|
* iOS: `flutter_gallery_ios__compile/release_size_bytes`
|
|
* APK/IPA size of minimal hello_world app
|
|
* Android: `hello_world_android__compile/release_size_bytes`
|
|
* iOS: `hello_world_ios__compile/release_size_bytes`
|
|
* Size of bundled `icudtl.dat`
|
|
* Compressed in APK: `hello_world_android__compile/icudtl_compressed_bytes`
|
|
* Uncompressed: `hello_world_android__compile/icudtl_uncompressed_bytes`
|
|
* Size of bundled `libflutter.so` (release mode)
|
|
* Compressed in APK: `hello_world_android__compile/libflutter_compressed_bytes`
|
|
* Uncompressed: `hello_world_android__compile/libflutter_uncompressed_bytes`
|
|
* Size of VM & isolate snapshots (data and instructions)
|
|
* Compressed in APK: `hello_world_android__compile/snapshot_compressed_bytes`
|
|
* Uncompressed: `hello_world_android__compile/snapshot_uncompressed_bytes`
|

## Comparing AOT Snapshot Sizes

A detailed comparison of AOT snapshot sizes can be performed using the [instructions documented here](https://github.com/flutter/flutter/wiki/Comparing-AOT-Snapshot-Sizes). |
