## Background
The Windows runner has a race at startup:
1. **Platform thread**: creates a hidden window
2. **Platform thread**: launches the Flutter engine
3. **UI/Raster threads**: renders the first frame
4. **Platform thread**: Registers a callback to show the window once the next frame has been rendered.
Steps 3 and 4 happen in parallel and it is possible for step 3 to complete before step 4 starts. In this scenario, the next frame callback is never called and the window is never shown.
As a result the `windows_startup_test`'s test, which [verifies that the "show window" callback is called](1f09a8662d/dev/integration_tests/windows_startup_test/windows/runner/flutter_window.cpp (L60-L64)), can flake if the first frame is rendered before the show window callback has been registered.
## Solution
This change makes the runner schedule a frame after it registers the next frame callback. If step 3 hasn't completed yet, this no-ops as a frame is already scheduled. If step 3 has already completed, a new frame will be rendered, which will call the next frame callback and show the window.

Adds the `namespace` property necessary for AGP 8 compatibility to the plugin templates, with the conditional logic to ensure that it doesn't break AGP <4.2, so that new plugins will be maximally compatible.

This PR removed the non-necessary required Koltin dependency. This is because the Kotlin Gradle adds the dependency on the standard library automatically.
Fixes#98212
*If you had to change anything in the [flutter/tests] repo, include a link to the migration guide as per the [breaking change policy]. *
1. Add iOS and macOS migration to mark "last upgraded" Xcode version to 14.3 to prevent `Update to recommended settings` warning.
2. Update iOS and macOS templates to same.
3. Update iOS template to set `BuildIndependentTargetsInParallel` to YES as suggested. I didn't add a migration for this since it seems like a minor optimization and I don't think it's worth a potentially botched/corrupted migration.
4. Run all example/integration test project to see migrator work.
5. Add some missing test projects to the build shard since I noticed they were missing and I had to build those manually outside `SHARD=build_tests`.
Fixes https://github.com/flutter/flutter/issues/125817
See https://github.com/flutter/flutter/pull/90304 for Xcode 13 example.
See https://docs.flutter.dev/reference/supported-platforms
I don't expect this to break anything, but if it does we can revert and figure out what else needs to happen first.
Without this change, engine changes upstream will get flagged in default flutter created apps.
* Add Linux unit tests to plugin template
Adds an example native unit test to the plugin template for Linux,
matching the structure we use for our 1P plugin unit tests. Once these
have been added for all platforms+languages, they will be documented on
a new plugin development page to explain their use.
While ideally we would adjust the engine APIs first to allow for testing
the method call handler directly, it's unclear when we will have time
for that work, and for a complex plugin most of the testing wouldn't be
at that layer anyway, so having the structure in place with the
limitations documented is still a significant improvement over having
nothing in the template.

* Add Windows unit tests to plugin template
Adds an example native unit test to the plugin template for Windows,
matching the format we use for our 1P plugin example app unit tests.
Once these have been added for all platforms+languages, they will be
documented on a new plugin development page to explain their use.
Since we don't appear to be running our current plugin e2e tests for
Windows, this adds a new configuration to run them. I haven't
`led`-tested this, so it may not work, but this will give a starting
point for getting them running.

* Minor fix
* Add test owner
* Fix typo
* Fix test feature flag
* Add Info.plist from build directory as input path to Thin Binary build phase
* fix directive ordering
* migrate benchmark, integration, and example tests
* Add an integration test to plugin template example
Dart unit tests don't exercise host-side plugin code at all, so the
example tests in the plugin template currently have very little
meaningful coverage. This adds an integration test to the example app
when creating a plugin, so that there's an example of how to actually
test that a complete round-trip plugin call works.
This is done as a separate template that's currently only used by the
plugin template because I don't know what a good example for a
non-plugin case would be that isn't largely just a duplicate of the
widget tests. However, the integration test pre-includes conditionals
around the parts that are plugin-specific so that it can more easily be
expanded to other use cases later (e.g., in
https://github.com/flutter/flutter/issues/68818).

* Add integration test to expected dependencies of a plugin app
* Test fixes
* Make an explicit test case
Increases the minimum macOS deployment target from macOS 10.13 (High Sierra) to 10.14 (Mojave) in the macOS app templates.
Includes:
* Update migration for macOS 10.11 apps to upgrade to 10.14
* Adds migration for macOS 10.13 apps to upgrade to 10.14
* Apply migration to all examples, and integration tests
This does not increase version in the plugin templates since those will need to wait until the 10.14 framework rolls to stable channel, so new plugins can build with apps created with `flutter create` on stable channel.
Issue: https://github.com/flutter/flutter/issues/114445
See RFC: http://flutter.dev/go/flutter-drop-macOS-10.13-2022-q4
See previous patch: https://github.com/flutter/flutter/pull/107689
Previously developers had to edit their `Runner.rc` file to update their executable's version information. Now, version information will automatically be set from `flutter build`'s arguments or the `pubspec.yaml` file for new projects.

* Implement trackpad gestures in framework
* Touch and Pan/Zoom pointers have separate IDs now
* Handle trackpad pointer device type
* Respect supportedDevices for pan/zoom events
* Update after rebase
* Fix check failures
* Avoid error with very short drags
* Address feedback
* Refactor drag event handler
* Address more feedback
* Add some missing punctuation
This patch adds an additional check to ensure the target length of a string is within the supported maximum string length prior to calling WideCharToMultiByte/MultiByteToWideChar in the Windows runner template.
This is to prevent resize() from failing if called with a count > std::string::max_size().
According to Win32 API docs (WideCharToMultiByte, MultiByteToWideChar) it's the caller responsibility to make sure the buffers are correctly allocated.

This change updates the platform runners in the benchmarks subdir.
I've attempted to replace the entire group with new code as if the project were recreated with flutter create so that they don't become a Frankenstein of minor changes to make it work again, but just plain old generated code that can be replaced and updated in place.

The first of three or four changes to update the platform directories of the packages in the Flutter repo that have out date platform code.
This batch includes updating the flutter_view example, updating the sanity check numbers in analyze.dart, and adding some missing Podfiles in the examples. I also eliminated some trailing whitespace in the templates for Android.
