Opening a Swift package in Xcode generates `.build` and `.swiftpm` directories. These should be ignored as they contain intermediary build artifacts that aren't meant to be checked-in.

Stop running link hooks in debug mode.
Rationale: link hooks only get access to tree-shaking info in release builds, so they can't do anything meaningful in debug builds. Debug builds should be fast as development cycle, so running less is better.
More details:
* https://github.com/dart-lang/native/issues/1252
Also: rolls packages to latest versions.
## Implementation details
The decision whether linking is enabled is made as follows:
* For normal builds `build_info.dart::BuildMode` is used to determine whether Dart is compiled in JIT or AOT mode.
* Testers always run in JIT, so no linking.
* Native asset dry runs only run for JIT builds (e.g only when hot reload and hot restart are enabled).
## Testing
The integration test is updated to output an asset for linking if `BuildConfig.linkingEnabled` is true, and to output an asset for bundling directly if linking is not enabled.
PR to pave the way for https://github.com/flutter/engine/pull/53001 to re-land
Summary:
- Enforces use of Kotlin >= `1.7.0` (please see below note)
- Fixes ci failures that prevented the above PR from landing.
Details:
Because it landed initially, we are able to fake the roll in this PR to fix all the tests ([see my comment](https://github.com/flutter/flutter/pull/149204#discussion_r1617924772)).
Fixes all the tests that failed:
1. `module_test` failing on multiple platforms (3/9 of the failures).
Failure is
```
> Android resource linking failed
ERROR:/b/s/w/ir/x/t/flutter_module_test.KECMXW/hello/.android/plugins_build_output/device_info/intermediates/merged_res/release/values/values.xml:194: AAPT: error: resource android:attr/lStar not found.
```
This is a rather unhelpful error message but some [folks online suggest](https://stackoverflow.com/a/69050529) that upgrading your `compileSdk` version fixes this.
These resolve when I remove the dependency on the long discontinued [package_info](https://pub.dev/packages/package_info) and [device_info](https://pub.dev/packages/device_info) packages, perhaps because they are transitively pulling in low `compileSdk` versions? This is unclear to me.
2. `module_custom_host_app_name_test` was failing for the same reason (another 3/9, or cumulative 6/9).
3. `tool_integration_tests_3_4` was a flake ð (7/9)
4. `framework_tests_slow` needed a newer version of the Kotlin Gradle plugin (the flutter tool tells us this, so I just upgraded as suggested) and it resolved (8/9)
5.`android_preview_tool_integration_tests` needed newer AGP and KGP versions. I also refactored the tests, and bumped our error versions, fixing https://github.com/flutter/flutter/issues/142653.
**Note that the bump to KGP is not in line with our policy** - we didn't warn for `1.5.0-1.6.x` for a release (or at all) before dropping support. But I think it might still be justified:
- The bump to our androidx libraries unblocks ongoing Scribe work, and also includes a fix for a [memory leak](https://github.com/flutter/flutter/issues/129307#issuecomment-1601636959) and a [crash on folding phones](https://github.com/flutter/flutter/issues/114868#issuecomment-2133226962), among many other bug fixes.
- Gradle [doesn't test on half of that range](https://docs.gradle.org/current/userguide/compatibility.html#kotlin), and so we implicitly can't claim to support it either. More generally, our Java and Kotlin support ranges should probably strictly fall within what Gradle tests.
This PR adds support invoking `link.dart` hooks.
Link hooks can add new assets. Link hooks can transform assets sent to link hook from build hooks.
This PR does not yet add support for getting tree-shake information in the link hooks. This is pending on defining the `resources.json` format (https://github.com/dart-lang/sdk/issues/55494).
Issue:
* https://github.com/flutter/flutter/issues/146263
## Implementation considerations
The build hooks could be run before Dart compilation and the link hooks after Dart compilation. (This is how it's done in Dart standalone.) However, due to the way the `Target`s are set up, this would require two targets and serializing and deserializing the `BuildResult` in between these. This would lead to more code but no benefits. Currently there is nothing that mandates running build hooks before Dart compilation.
## Testing
* The unit tests verify that the native_assets_builder `link` and `linkDryRun` would be invoked with help of the existing fake.
* The native assets integration test now also invokes an FFI call of a package that adds the asset during the link hook instead of the build hook.
* In order to keep coverage of the `flutter create --template=package_ffi`, `flutter create` is still run and the extra dependency is added and an extra ffi call is added. (Open to alternative suggestions.)
Adds an empty privacy manifest, and commented out code to include it in the build, to the plugin template. This will make it much easier to explain how to add a privacy manifest in plugin docs, since instead of explaining the format of the file from scratch and providing example code to inculde it, we can just instruct people to add entries to an exisitng file and then uncomment a line or two. This will also make it much easier to figure out from the template output itself how to add support for people who don't find the documentation.

When Swift Package Manager feature is enabled, create app and create plugin will have Swift Package Manager integration already added and will not need to undergo a migration.
Fixes https://github.com/flutter/flutter/issues/146371.
```
flutter config --enable-swift-package-manager
flutter create --ios-language swift --platforms ios,macos swift_app_name
flutter create --ios-language objc --platforms ios objc_app_name
flutter create --template=plugin --ios-language swift --platforms ios,macos swift_plugin_name
flutter create --template=plugin --ios-language objc --platforms ios objc_plugin_name
```
It looks like the formatter was updated.
We have a test running on the FFIgen repo that checks that rerunning the generated bindings with FFIgen generates identical bindings.
Closes:
* https://github.com/dart-lang/native/issues/1072
* Adds support for `flutter test --wasm`.
* The test compilation flow is a bit different now, so that it supports compilers other than DDC. Specifically, when we run a set of unit tests, we generate a "switchboard" main function that imports each unit test and runs the main function for a specific one based off of a value set by the JS bootstrapping code. This way, there is one compile step and the same compile output is invoked for each unit test file.
* Also, removes all references to `dart:html` from flutter/flutter.
* Adds CI steps for running the framework unit tests with dart2wasm+skwasm
* These steps are marked as `bringup: true`, so we don't know what kind of failures they will result in. Any failures they have will not block the tree at all yet while we're still in `bringup: true`. Once this PR is merged, I plan on looking at any failures and either fixing them or disabling them so we can get these CI steps running on presubmit.
This fixes https://github.com/flutter/flutter/issues/126692
This makes several changes to flutter web app bootstrapping.
* The build now produces a `flutter_bootstrap.js` file.
* By default, this file does the basic streamlined startup of a flutter app with the service worker settings and no user configuration.
* The user can also put a `flutter_bootstrap.js` file in the `web` subdirectory in the project directory which can have whatever custom bootstrapping logic they'd like to write instead. This file is also templated, and can use any of the tokens that can be used with the `index.html` (with the exception of `{{flutter_bootstrap_js}}`, see below).
* Introduced a few new templating tokens for `index.html`:
* `{{flutter_js}}` => inlines the entirety of `flutter.js`
* `{{flutter_service_worker_version}}` => replaced directly by the service worker version. This can be used instead of the script that sets the `serviceWorkerVersion` local variable that we used to have by default.
* `{{flutter_bootstrap_js}}` => inlines the entirety of `flutter_bootstrap.js` (this token obviously doesn't apply to `flutter_bootstrap.js` itself).
* Changed `IndexHtml` to be called `WebTemplate` instead, since it is used for more than just the index.html now.
* We now emit warnings at build time for certain deprecated flows:
* Warn on the old service worker version pattern (i.e.`(const|var) serviceWorkerVersion = null`) and recommends using `{{flutter_service_worker_version}}` token instead
* Warn on use of `FlutterLoader.loadEntrypoint` and recommend using `FlutterLoader.load` instead
* Warn on manual loading of `flutter_service_worker.js`.
* The default `index.html` on `flutter create` now uses an async script tag with `flutter_bootstrap.js`.
## Description
This PR simplifies one external link in a commented section of the Android manifest template.
## Related Issue
Fixes https://github.com/flutter/flutter/issues/144249
## Tests
Documentation only PR.
This is a direct revert of (the revert of (the reland of (the policy pr))): https://github.com/flutter/flutter/pull/143132.
The only change is:
1. to put a conditional all on one line, because the packages repository has a test that uses an old flutter project to make sure nothing regresses. The old project uses an old gradle version, and the old gradle version bundles an old groovy version, and the old groovy version has a bug where lines that start with `&&` don't always work: https://issues.apache.org/jira/browse/GROOVY-7218 (I enjoy that the revert reason ends up providing another strong justification to go forward with the policy). Also thanks to @reidbaker for pointing out this bug.
2. I also made a slight formatting change to the messages that print when out of the support bounds, which I think looks slightly better.
I tested this with on a branch that included a revert of https://github.com/flutter/flutter/pull/142008, and was able to recreate the failure and verify that it was resolved by 1).
Re land of https://github.com/flutter/flutter/pull/142000.
Differences:
1. Fixed the test that was failing in postsubmit. The reason was that the Flutter Gradle Plugin was being applied after KGP in that test, so we couldn't find the KGP version. This caused a log, and the test expects no logs. I moved FGP to after KGP
2. Added to the logs for when we can't find AGP. Change is from
> "Warning: unable to detect project AGP version. Skipping version checking."
to
> ~"Warning: unable to detect project AGP version. Skipping version checking. \nThis may be because you have applied the Flutter Gradle Plugin after AGP."~
update: the above is wrong, changed to
> "Warning: unable to detect project KGP version. Skipping version checking. \nThis may be because you have applied AGP after the Flutter Gradle Plugin."
3. Added a note to the app-level build.gradle templates that FGP must go last
> // The Flutter Gradle Plugin must be applied after the Android and Kotlin Gradle plugin.
Re-sets two jvmargs that were getting cleared because we set a value for `-Xmx`. Could help with https://github.com/flutter/flutter/issues/142957. Copied from comment here https://github.com/flutter/flutter/issues/142957:
>Two random things I ran into while looking into this that might help:
>
>1. Gradle has defaults for a couple of the jvmargs, and setting any one of them clears those defaults for the others (bug here https://github.com/gradle/gradle/issues/19750). This can cause the "Gradle daemon to consume more and more native memory until it crashes", though the bug typically has a different associated error. It seems worth it to re-set those defaults.
>2. There is a property we can set that will give us a heap dump on OOM ([-XX:HeapDumpOnOutOfMemoryError](https://docs.oracle.com/javase/8/docs/technotes/guides/troubleshoot/clopts001.html))
Mostly just a find and replace from `find . -name gradle.properties -exec sed -i '' 's/\-Xmx4G/-Xmx4G\ \-XX:MaxMetaspaceSize=2G\ \-XX:+HeapDumpOnOutOfMemoryError/g' {} \;`, with the templates and the one test that writes from a string replaced by hand. I didn't set a value for `MaxMetaspaceSize` in the template files because I want to make sure this value doesn't cause problems in ci first (changes to the templates are essentially un-revertable for those who `flutter create` while the changes exist).
Previously, we were comparing the signed int `target_length` (returned by WideCharToMultiByte) to a size_t string length, resulting in a signed/unsigned comparison warning as follows:
```
windows\runner\utils.cpp(54,43): warning C4018: '>': signed/unsigned mismatch
```
WideCharToMultiByte returns:
* 0 on error
* the number of bytes written to the buffer pointed to by its fifth parameter, lpMultiByteStr, on success.
As a result it's safe to store the return value in an unsigned int, which eliminates the warning.
No changes to tests since this is dependent on end-user project settings/modifications and does not trigger a warning with default project settings.

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.
On `Podfile`:
```ruby
flutter_application_path = '../flutter_module'
load File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')
target 'OCProject' do
# Comment the next line if you don't want to use dynamic frameworks
use_frameworks!
# Pods for OCProject
# install_all_flutter_pods(flutter_application_path)
# install_flutter_engine_pod(flutter_application_path)
# install_flutter_application_pod(flutter_application_path)
install_flutter_plugin_pods(flutter_application_path)
end
post_install do |installer|
flutter_post_install(installer)
end
```
Encountering the following error after executing `pod install`:
```shell
pod install
[!] Invalid `Podfile` file: undefined method `flutter_relative_path_from_podfile' for #<Pod::Podfile:0x000000010e74c520 @defined_in_file=#<Pathname:/Users/lxf/gitHub/flutter_hybrid_bug/OCProject/Podfile>, @internal_hash={}, @root_target_definitions=[#<Pod::Podfile::TargetDefinition label=Pods>], @current_target_definition=#<Pod::Podfile::TargetDefinition label=Pods>>

#
# -------------------------------------------
```
The `flutter_relative_path_from_podfile` method is in `flutter_tools/bin/podhelper.rb`, but now `flutter_tools/bin/podhelper.rb` is only required in `install_all_flutter_pods` in `podhelper.rb.tmpl`.
Sometimes we only need to use the `install_flutter_plugin_pods` method in podhelper.rb. For example, using `Shorebird` in an iOS hybird app scenario, we need to build `Flutter.xcframework` and `App.xcframework` and embed them into the iOS native project. In order to avoid unnecessary conflicts, use `install_flutter_plugin_pods` method to install Flutter plugin pods.
[Shorebird - Code Push In Hybrid Apps](https://docs.shorebird.dev/guides/hybrid-app/ios)
So I adjust the position of `require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)`.

I continued [my mission](https://github.com/flutter/flutter/pull/141431) to find as many typos as I could. This time it's a smaller set than before.
There is no need for issues since it's a typo fix.
`swift-format` alphabetizes imports. Alphabetize them in swift template files and integration tests.
I found this as part of https://github.com/flutter/flutter/issues/41129 running `swift-import` on packages.
Added missing required newline at end of some `.gitignore` files. All other `.gitignore` files ends with a newline except the changed ones, hence the PR.
> *List which issues are fixed by this PR. You must list at least one issue. An issue is not required if the PR fixes something trivial like a typo.*
**Not listing any issues because of trivial fixes as mentioned above.**
Change the following in the `flutter create` templates. I didn't make any auto-migrations for existing apps because none seem that critical:
1. Turn on `ASSETCATALOG_COMPILER_GENERATE_SWIFT_ASSET_SYMBOL_EXTENSIONS` in iOS and macOS.
1. Turn on `BuildIndependentTargetsInParallel` in macOS template. https://github.com/flutter/flutter/pull/125827/files#r1181817619
1. Turn on `DEAD_CODE_STRIPPING` in macOS template.
1. Set `ENABLE_USER_SCRIPT_SANDBOXING=NO` in iOS and macOS template. `flutter` scripts don't work with this on. This might require a migration in the future to explicitly turn this one off. However at least for now if the setting isn't present it defaults to `NO`.
Add migration for `LastUpgradeVersion` so users won't see these validation issues in Xcode.
Run migrator on all the example apps. A few aren't Flutter apps so I edited them in Xcode.
