After this PR, `<Plugin>.isDevDependency` is resolved based on the following logic, IFF:
- The plugin comes from a package _A_ listed in the app's package's `dev_dependencies: ...`
- The package _A_ is not a normal dependency of any transitive non-dev dependency of the app
See [`compute_dev_dependencies_test.dart`](51676093a3/packages/flutter_tools/test/general.shard/compute_dev_dependencies_test.dart) for probably the best specification of this behavior.
We (still) do not write the property to disk (i.e. it never makes it to `.flutter-plugins-dependencies`), so there is no impact to build artifacts at this time; that would come in a follow-up PR (and then follow-up follow-up PRs for the various build systems in both Gradle and Xcode to actually use that value to omit dependencies).
Some tests had to be updated; for the most part it was updating the default `ProcessManager` because a call to `dart pub deps --json` is now made in code that computes what plugins are available, but there should be no change in behavior.
_/cc @jonasfj @sigurdm for FYI only (we talked on an internal thread about this; see https://github.com/dart-lang/sdk/issues/56968)._

This PR introduces the `dartFileName` parameter for platform plugin configurations with Dart platform implementations. This new parameter allows plugin developers to specify a custom path to the file where the `dartPluginClass` is defined.
**Implementation is opt-in**. `dartFileName` is completely optional and is taken in account only with `dartClassName`. Possibility to set `dartClassName` without `dartFileName` remains.
**Implementation is backward compatible** â existing configurations using only `dartClassName` remain fully supported. If `dartFileName` is omitted, the system falls back to the previous behavior of deriving the file name from the plugin name.
## Example
```yaml
flutter:
plugin:
platforms:
some_platform:
dartPluginClass: MyPlugin
dartFileName: 'src/my_plugin_implementation.dart'
```
fixes#152833
Currently, if creating a symlink on Windows fails due to `ERROR_ACCESS_DENIED`, you'll get an error message like:
```
Error: ERROR_ACCESS_DENIED file system exception thrown while trying to create a symlink from source to dest
```
The `source` and `dest` paths are incorrect.
This will help us debug: https://github.com/flutter/flutter/issues/153758
These changes allow to override existing native endorsed (federated & inline) plugins with e.g. non-endorsed plugin implementations via direct dependencies as described in the section *Platform implementation selection* in the [design doc](https://docs.google.com/document/d/1LD7QjmzJZLCopUrFAAE98wOUQpjmguyGTN2wd_89Srs).
```yaml
# pubspec.yaml

dependencies:
my_plugin: ^0.0.1
my_plugin_android_alternative: ^0.0.1

This PR adds initial support for Swift Package Manager (SPM). Users must opt in. Only compatible with Xcode 15+.
Fixes https://github.com/flutter/flutter/issues/146369.
## Included Features
This PR includes the following features:
* Enabling SPM via config
`flutter config --enable-swift-package-manager`
* Disabling SPM via config (will disable for all projects)
`flutter config --no-enable-swift-package-manager`
* Disabling SPM via pubspec.yaml (will disable for the specific project)
```
flutter:
disable-swift-package-manager: true
```
* Migrating existing apps to add SPM integration if using a Flutter plugin with a Package.swift
* Generates a Swift Package (named `FlutterGeneratedPluginSwiftPackage`) that handles Flutter SPM-compatible plugin dependencies. Generated package is added to the Xcode project.
* Error parsing of common errors that may occur due to using CocoaPods and Swift Package Manager together
* Tool will print warnings when using all Swift Package plugins and encourage you to remove CocoaPods
This PR also converts `integration_test` and `integration_test_macos` plugins to be both Swift Packages and CocoaPod Pods.
## How it Works
The Flutter CLI will generate a Swift Package called `FlutterGeneratedPluginSwiftPackage`, which will have local dependencies on all Swift Package compatible Flutter plugins.
The `FlutterGeneratedPluginSwiftPackage` package will be added to the Xcode project via altering of the `project.pbxproj`.
In addition, a "Pre-action" script will be added via altering of the `Runner.xcscheme`. This script will invoke the flutter tool to copy the Flutter/FlutterMacOS framework to the `BUILT_PRODUCTS_DIR` directory before the build starts. This is needed because plugins need to be linked to the Flutter framework and fortunately Swift Package Manager automatically uses `BUILT_PRODUCTS_DIR` as a framework search path.
CocoaPods will continue to run and be used to support non-Swift Package compatible Flutter plugins.
## Not Included Features
It does not include the following (will be added in future PRs):
* Create plugin template
* Create app template
* Add-to-App integration
Pre work for https://github.com/flutter/engine/pull/51229. Removes a lot of code referencing v1 of the android embedding, though not necessarily all of it (I may have missed some, it is hard to know).
Will hopefully make landing that PR less painful (or maybe painless?)
Part of https://github.com/flutter/flutter/issues/130277
Without this, if a user runs an app that has plugins that call method channels with the `preview` device, the app will build successfully, however, they will get a runtime error when their dart code tries to call the method channel that does not exist in the native build (which was pre-built and thus does not include the plugin code).
This change adds a validation when injecting plugins that will tool exit if the device-id is `preview` and their project contains plugins with method channels.
