This flag has been enabled by default for quite some time in `master`,
and in the current `stable`.
This is the first of many PRs to get rid of the flag and the deprecated
code it is guarding.
This auto-formats all *.dart files in the repository outside of the
`engine` subdirectory and enforces that these files stay formatted with
a presubmit check.
**Reviewers:** Please carefully review all the commits except for the
one titled "formatted". The "formatted" commit was auto-generated by
running `dev/tools/format.sh -a -f`. The other commits were hand-crafted
to prepare the repo for the formatting change. I recommend reviewing the
commits one-by-one via the "Commits" tab and avoiding Github's "Files
changed" tab as it will likely slow down your browser because of the
size of this PR.

Closes https://github.com/flutter/flutter/issues/158012.
This is (effectively) a user-facing NOP, which is exchanging an
on-by-default command-line argument (`--implicit-pubspec-resolution`)
for an off-by-default global feature flag
(`explicit-package-dependencies`). It matches the mental model better,
is less painstaking to maintain and feed throughout, and will be easier
to globally flip on/off in a future PR.

Work towards https://github.com/flutter/flutter/issues/157819. **No behavior changes as a result of this PR**.
Based on a proof of concept by @jonahwilliams (https://github.com/flutter/flutter/pull/157818).
The existence of this flag (which for the time being, defaults to `true`) implies the following:
1. The (legacy, deprecated) `.flutter-plugins` file is not generated:
https://docs.flutter.dev/release/breaking-changes/flutter-plugins-configuration
2. The (legacy, deprecated) `package:flutter_gen` is not synthetically generated:
https://github.com/flutter/website/pull/11343
(awaiting website approvers, but owners approve this change)
This change creates `useImplicitPubspecResolution` and plumbs it through as a required variable, parsing it from a `FlutterCommand.globalResults` where able. In tests, I've defaulted the value to `true` 100% of the time - except for places where the value itself is acted on directly, in which case there are true and false test-cases (e.g. localization and i10n based classes and functions).
I'm not extremely happy this needed to change 50+ files, but is sort of a result of how inter-connected many of the elements of the tools are. I believe keeping this as an explicit (flagged) argument will be our best way to ensure the default behavior changes consistently and that tests are running as expected.
This reverts commit 7cdc23b3e1.
The failure in the `native_assets_test` integration test on Windows was caused by the DevTools process not being shutdown by the `ColdRunner` when running the profile mode portion of the test. This resulted in the test being unable to clean up the project created by the test as DevTools was still holding onto a handle within the directory. This PR adds back the mistakenly removed DevTools shutdown logic in the `ColdRunner`.

This change is a major step towards moving away from shipping DDS via Pub.
The first component of this PR is the move away from importing package:dds to launch DDS. Instead, DDS is launched out of process using the `dart development-service` command shipped with the Dart SDK. This makes Flutter's handling of DDS consistent with the standalone Dart VM.
The second component of this PR is the initial work to prepare for the removal of instances of DevTools being served manually by the flutter_tool, instead relying on DDS to serve DevTools. This will be consistent with how the standalone Dart VM serves DevTools, tying the DevTools lifecycle to a live DDS instance. This will allow for the removal of much of the logic needed to properly manage the lifecycle of the DevTools server in a future PR. Also, by serving DevTools from DDS, users will no longer need to forward a secondary port in remote workflows as DevTools will be available on the DDS port.
There's two remaining circumstances that will prevent us from removing DevtoolsRunner completely:
- The daemon's `devtools.serve` endpoint
- `flutter drive`'s `--profile-memory` flag used for recording memory profiles
This PR also includes some refactoring around `DebuggingOptions` to reduce the number of debugging related arguments being passed as parameters adjacent to a `DebuggingOptions` instance.

The revert of the revert is in the first commit, the fix in the commit on top.
The move of the fakes for packages/flutter_tools/test/general.shard/resident_runner_test.dart was erroneous before, as it was trying to use setters instead of a private field. This PR changes the private `_devFS` field in the fake to be a public `fakeDevFS` in line with other fakes.
## Original PR description
Native assets in other build systems are not built with `package:native_assets_builder` invoking `build.dart` scripts. Instead all packages have their own blaze rules. Therefore we'd like to not depend on `package:native_assets_builder` from flutter tools in g3 at all.
This PR aims to move the imports of `native_assets_builder` and `native_assets_cli` into the `isolated/` directory and into the files with a `main` function that are not used in with other build systems.
In order to be able to remove all imports in files used by other build systems, two new interfaces are added `HotRunnerNativeAssetsBuilder` and `TestCompilerNativeAssetsBuilder`. New parameters are then piped all the way through from the entry points:
* bin/fuchsia_tester.dart
* lib/executable.dart
The build_system/targets dir is already excluded in other build systems.
So, after this PR only the two above files and build_system/targets import from `isolated/native_assets/` and only `isolated/native_assets/` import `package:native_assets_cli` and `package:native_assets_builder`.

Add a new `BuildTargets` class that provides commonly used build targets. And avoid importing files from `build_system/targets` except from the top level entrypoints or from top level commands.
Also move `scene_importer.dart` and `shader_compiler.dart` into `build_system/tools` because they are not `Target` classes, but wrapper for certain tools.
With this change, we can ignore all files in `build_system/targets` internally and make PR #142709 easier to land internally. See cl/603434066 for the corresponding internal change.

Also note that I have opted to add a new variable in `globals.dart` for `BuildTargets` in this PR, but I know that we are trying to get rid of globals. Several alternatives that I was considering:
1. Add a new field in `BuildSystem` that returns a `BuildTargets` instance. Since `BuildSystem` is already in `globals`, we can access build targets using `globals.buildSystem.buildTargets` without adding a new global variable.
2. Properly inject the `BuildTargetsImpl` instance from the top level `executable.dart` and top level commands.
Let me know if you want me to do one of the above instead. Thanks!
Refactors `ShaderTarget` to make it opaque as to whether it's using Impeller or SkSL and instead has it focus on the target platform it's generating for.
ImpellerC includes SkSL right now whether you ask for it or not.
The tester target also might need SkSL or Vulkan depending on whether `--enable-impeller` is passed.

Rolls the packages from https://github.com/dart-lang/native in the native assets implementation.
Most notable we're refactoring `package:native_assets_cli` for `build.dart` use.
Therefore, all imports to that package for Flutter/Dart should be to the implementation internals that are no longer visible for `build.dart` writers. Hence all the import updates.
No behavior in Flutter apps should change.
This PR also updates the template to use the latests version of `package:native_assets_cli` which no longer exposes all the implementation details.

There is no need for issues since it's a typo fix.
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.
Support for FFI calls with `@Native external` functions through Native assets on MacOS and iOS. This enables bundling native code without any build-system boilerplate code.
For more info see:

### Implementation details for MacOS and iOS.
Dylibs are bundled by (1) making them fat binaries if multiple architectures are targeted, (2) code signing these, and (3) copying them to the frameworks folder. These steps are done manual rather than via CocoaPods. CocoaPods would have done the same steps, but (a) needs the dylibs to be there before the `xcodebuild` invocation (we could trick it, by having a minimal dylib in the place and replace it during the build process, that works), and (b) can't deal with having no dylibs to be bundled (we'd have to bundle a dummy dylib or include some dummy C code in the build file).
The dylibs are build as a new target inside flutter assemble, as that is the moment we know what build-mode and architecture to target.
The mapping from asset id to dylib-path is passed in to every kernel compilation path. The interesting case is hot-restart where the initial kernel file is compiled by the "inner" flutter assemble, while after hot restart the "outer" flutter run compiled kernel file is pushed to the device. Both kernel files need to contain the mapping. The "inner" flutter assemble gets its mapping from the NativeAssets target which builds the native assets. The "outer" flutter run get its mapping from a dry-run invocation. Since this hot restart can be used for multiple target devices (`flutter run -d all`) it contains the mapping for all known targets.
### Example vs template
The PR includes a new template that uses the new native assets in a package and has an app importing that. Separate discussion in: https://github.com/flutter/flutter/issues/131209.
### Tests
This PR adds new tests to cover the various use cases.
* dev/devicelab/bin/tasks/native_assets_ios.dart
* Runs an example app with native assets in all build modes, doing hot reload and hot restart in debug mode.
* dev/devicelab/bin/tasks/native_assets_ios_simulator.dart
* Runs an example app with native assets, doing hot reload and hot restart.
* packages/flutter_tools/test/integration.shard/native_assets_test.dart
