Partially resolves[^1] https://github.com/flutter/flutter/issues/139774.
Effectively reverts https://github.com/flutter/flutter/pull/125581.
The main change here is that I deleted and recreated the macos Xcode project for this integration test (hence the large diff). I tried fixing the existing project first, but it was set up quite differently, andâfor whatever reasonâthe integration test would get stuck trying to load `dev/integration_tests/flavors/integration_test/integration_test.dart`.
I verified that this works locally, but I don't know if it's possible to run this on the devicelab try pool to verify that it works on devicelab hardware.
[^1]: I would not close the issue until 1) this PR lands, 2) the integration test consistently passes on CI, and 3) macOS support for flavors is publicly documented.
1. Move leak_tracker and leak_tracker_testing out of direct dependencies.
2. Move leak_tracker_flutter_testing from dev to prod dependencies for flutter_test
It is prerequisite for https://github.com/flutter/flutter/issues/135856
Pinning the package:web dependency constrains downstream packages from
using newer versions and making sure they support the version pinned in
Flutter. Since the usage of package:web in Flutter is light, we should
instead have a small shim like the engine and keep package:web as a dev
dependency only.
ObjC->Swift plugin migration caused a size regression in the gallery app because the Swift runtime was also pulled in.
The gallery app minimum target version is iOS 11.0, which predates Swift ABI compatibility. Pre iOS 12.2 apps embedded the Swift runtime since there wasn't one available to use in the OS.
Add `FLUTTER_XCODE_IPHONEOS_DEPLOYMENT_TARGET` to the compile perf test environment, which gets translated by the tool to an Xcode build setting:
```

```
On my machine on main
```
"release_size_bytes": 43717389,

becomes
```
"release_size_bytes": 40679432,
```
Fixes https://github.com/flutter/flutter/issues/139605
I did not include the `'// flutter_ignore_for_file: stopwatch (see analyze.dart)'` directive since it's currently not used, and adding that shouldn't be too difficult.
The generated file is a `.cc` file that does not need header guards. This change updates the template that's used to generate that `.cc` file.
No tests as this is a refactoring with no semantic changes.
The generated `.cc` file in the engine will be updated by https://github.com/flutter/engine/pull/48993

Original Description:
* Remove all use of global variables.
* Always pass in all dependencies, only create them in main or in tests.
* Pass in the "print" primitive.

Tests for `app_bar.0`, `app_bar.1`, `app_bar.2`, `app_bar.3`, `sliver_app_bar.1` and `sliver_app_bar.4` were already present. But directory name was `appbar` rather than `app_bar`. I've renamed the directory to `app_bar` since example files uses that only.

This change reverts the following previous change:
Original Description:
Provides support for conditional bundling of assets through the existing `--flavor` option for `flutter build` and `flutter run`. Closes https://github.com/flutter/flutter/issues/21682. Resolves https://github.com/flutter/flutter/issues/136092
## Change
Within the `assets` section pubspec.yaml, the user can now specify one or more `flavors` that an asset belongs to. Consider this example:
```yaml
# pubspec.yaml
flutter:
assets:
- assets/normal-asset.png
- path: assets/vanilla/ice-cream.png
flavors:
- vanilla
- path: assets/strawberry/ice-cream.png
flavors:
- strawberry
```
With this pubspec,
* `flutter run --flavor vanilla` will not include `assets/strawberry/ice-cream.png` in the build output.
* `flutter run --flavor strawberry` will not include `assets/vanilla/ice-cream.png`.
* `flutter run` will only include `assets/normal-asset.png`.
## Open questions
* Should this be supported for all platforms, or should this change be limited to ones with documented `--flavor` support (Android, iOS, and (implicitly) MacOS)? This PR currently only enables this feature for officially supported platforms.
## Design thoughts, what this PR does not do, etc.
### This does not provide an automatic mapping/resolution of asset keys/paths to others based on flavor at runtime.
The implementation in this PR represents a simplest approach. Notably, it does not give Flutter the ability to dynamically choose an asset based on flavor using a single asset key. For example, one can't use `Image.asset('config.json')` to dynamically choose between different "flavors" of `config.json` (such as `dev-flavor/config.json` or `prod-flavor/config.json`). However, a user could always implement such a mechanism in their project or in a library by examining the flavor at runtime.
### When multiple entries affect the same file and 1) at least one of these entries have a `flavors` list provided and 2) these lists are not equivalent, we always consider the manifest to be ambiguous and will throw a `ToolExit`.
<details>
For example, these manifests would all be considered ambiguous:
```yaml
assets:
- assets/
- path: assets/vanilla.png
flavors:
- vanilla
assets:
- path: assets/vanilla/
flavors:
- vanilla
- path: assets/vanilla/cherry.png
flavor:
- cherry
# Thinking towards the future where we might add glob/regex support and more conditions other than flavor:
assets:
- path: assets/vanilla/**
flavors:
- vanilla
- path: assets/**/ios/**
platforms:
- ios
# Ambiguous in the case of assets like "assets/vanilla/ios/icon.svg" since we
# don't know if flavor `vanilla` and platform `ios` should be combined using or-logic or and-logic.
```
See [this review comment thread](https://github.com/flutter/flutter/pull/132985#discussion_r1381909942) for the full story on how I arrived at this decision.

### This does not support Android's multidimensional flavors feature (in an intuitive way)
<details>
Conder this excerpt from a Flutter project's android/app/build.gradle file:
```groovy
android {
// ...
flavorDimensions "mode", "api"
productFlavors {
free {
dimension "mode"
applicationIdSuffix ".free"
}
premium {
dimension "mode"
applicationIdSuffix ".premium"
}
minApi23 {
dimension "api"
versionNameSuffix "-minApi23"
}
minApi21 {
dimension "api"
versionNameSuffix "-minApi21"
}
}
}
```
In this setup, the following values are valid `--flavor` are valid `freeMinApi21`, `freeMinApi23`, `premiumMinApi21`, and `premiumMinApi23`. We call these values "flavor combinations". Consider the following from the Android documentation[^1]:
> In addition to the source set directories you can create for each individual product flavor and build variant, you can also create source set directories for each combination of product flavors. For example, you can create and add Java sources to the src/demoMinApi24/java/ directory, and Gradle uses those sources only when building a variant that combines those two product flavors.
>
> Source sets you create for product flavor combinations have a higher priority than source sets that belong to each individual product flavor. To learn more about source sets and how Gradle merges resources, read the section about how to [create source sets](https://developer.android.com/build/build-variants#sourcesets).
This feature will not behave in this way. If a user utilizes this feature and also Android's multidimensional flavors feature, they will have to list out all flavor combinations that contain the flavor they want to limit an asset to:
```yaml
assets:
- assets/free/
flavors:
- freeMinApi21
- freeMinApi23
```
This is mostly due to a technical limitation in the hot-reload feature of `flutter run`. During a hot reload, the tool will try to update the asset bundle on the device, but the tool does not know the flavors contained within the flavor combination (that the user passes to `--flavor`). Gradle is the source of truth of what flavors were involved in the build, and `flutter run` currently does not access to that information since it's an implementation detail of the build process. We could bubble up this information, but it would require a nontrivial amount of engineering work, and it's unclear how desired this functionality is. It might not be worth implementing.

Updates Gradle version for Flutter project templates and integration tests to at least 7.6.3 (changed all of those with versions below it) to fix security vulnerability.
Part of fix for https://github.com/flutter/flutter/issues/138336.
Support for FFI calls with `@Native external` functions through Native assets on Android. This enables bundling native code without any build-system boilerplate code.
For more info see:
* https://github.com/flutter/flutter/issues/129757
### Implementation details for Android.
Mainly follows the design of the previous PRs.
For Android, we detect the compilers inside the NDK inside SDK.
And bundling of the assets is done by the flutter.groovy file.
The `minSdkVersion` is propagated from the flutter.groovy file as well.
The NDK is not part of `flutter doctor`, and users can omit it if no native assets have to be build.
However, if any native assets must be built, flutter throws a tool exit if the NDK is not installed.
Add 2 app is not part of this PR yet, instead `flutter build aar` will tool exit if there are any native assets.
Upgrades agp versions and lockfiles for `dev/`. Also changes the lockfile generation script to represent the newer form of the `settings.gradle` template, and therefore also propagates these changes.
~~Potentially related to https://github.com/flutter/flutter/issues/134419~~, but worth doing anyways. (not actually related)
Write Tests for API Examples of `cupertino_text_field.0`, `data_table.0`, `icon_button.2` & `ink_well.0`
Note: test for `cupertino_text_field.0` was already there but it was named `cupertino_text_field.0.dart`. I renamed it to `cupertino_text_field.0_test.dart`.
Part of #130459
I plan to extend the prepare_package.dart script to upload the flutter preview device ([design doc](https://docs.google.com/document/d/1AzI-_Uk2v1LA2kKKFJ7gVD4xcakXJ6yVZiS5Ek6RHtg/edit#heading=h.byp03plw7mg9)).
However, given that that script is one large >1k line file, I decided to organize it into smaller libraries in this PR. There should be no behavioral change in this PR, this is a cleanup only. I made the following changes:
1. Created a //dev/bots/prepare_package/ directory to contain helper libraries
2. Moved everything but the `main()` function in //dev/bots/prepare_package.dart into one of 4 helper libraries under the new directory from step 1:
a. archive_creator.dart which contains the code that creates archive directory locally on disk
b. archive_publisher.dart which contains the code that uploads the archive to cloud storage
c. common.dart for shared constants and definitions
d. process_runner.dart for an abstraction over running sub-processes
3. Changed all definitions to `File` and `Directory` from `dart:io` to use the testable versions from `package:file`. This allowed me to use the `MemoryFileSystem` in the unit tests, rather than creating real temp file system directories.
Addresses #63507, and is a follow up to the engine PR https://github.com/flutter/engine/pull/46857
Changes the font family string when attempting to use Apple system fonts to the new proxies added by the engine. For the "Text" font this will be more secure in the future against possible changes to Apple's API. For the "Display" font, this will now work correctly when it didn't before.
I checked the letter spacing values against a native app for all font sizes between 17-28. I made a few adjustments to better match native, but especially for the "Text" font we were either really close, or close enough to not make a large breaking change to default fonts worth it.
| Before | After |

The smaller text in both the before and after should be the same. The large system font that Flutter used before was incorrect, which caused it to look more spread out. Now we use the correct font.
This updates the implementation to use the stopwatch from the Clock object and pipes it through to the TestWidgetsFlutterBinding so it will be kept in sync with FakeAsync.
Relands https://github.com/flutter/flutter/pull/138843 attempted to reland https://github.com/flutter/flutter/pull/137381 which attempted to reland #132291
Fixes https://github.com/flutter/flutter/issues/97761
1. The original change was reverted due to flakiness it introduced in tests that use fling gestures.
* Using a mocked clock through the test binding fixes this now
2. It was reverted a second time because a change at tip of tree broke it, exposing memory leaks, but it was not rebased before landing.
* These leaks are now fixed
3. It was reverted a third time, because we were so excellently quick to revert those other times, that we did not notice the broken benchmark that only runs in postsubmit.
* The benchmark is now fixed
- fix https://github.com/flutter/flutter/issues/53707 by having the test not expect a timeout but instead actually look for the retry message
- simplify the `--task` option to only accept task names rather than also accepting paths
- remove some obsolete options that referred to the manifest which no longer seems to exist
