Closes https://github.com/flutter/flutter/issues/132162.
I did a tiny bit of minor cleanup but didn't want to go 🍔 beyond the
scope of this change. After it lands I'll update the Wiki.
## Before
```bash
$ fl run \
--local-engine-src-path=$ENGINE \
--local-engine=android_debug_unopt_arm64
```
... would try to use `host_debug_unopt` (i.e. Rosetta).
## After
```bash
$ fl run \
--local-engine-src-path=$ENGINE \
--local-engine=android_debug_unopt_arm64 \
--local-engine-host=host_debug_unopt_arm64
```
... uses `host_debug_unopt_arm64`, as specified.

Migrate tests in flutter/flutter. Once the tests here and in `*_customer_testing` are migrated, the default value of the migration flag will be changed from false to true, making the rounding hack disabled by default.
This PR aims to support Android's predictive back gesture when popping the entire Flutter app. Predictive route transitions between routes inside of a Flutter app will come later.
<img width="200" src="https://user-images.githubusercontent.com/389558/217918109-945febaa-9086-41cc-a476-1a189c7831d8.gif" />
### Trying it out
If you want to try this feature yourself, here are the necessary steps:
1. Run Android 33 or above.
1. Enable the feature flag for predictive back on the device under "Developer
options".
1. Create a Flutter project, or clone [my example project](https://github.com/justinmc/flutter_predictive_back_examples).
1. Set `android:enableOnBackInvokedCallback="true"` in
android/app/src/main/AndroidManifest.xml (already done in the example project).
1. Check out this branch.
1. Run the app. Perform a back gesture (swipe from the left side of the
screen).
You should see the predictive back animation like in the animation above and be able to commit or cancel it.
### go_router support
go_router works with predictive back out of the box because it uses a Navigator internally that dispatches NavigationNotifications!
~~go_router can be supported by adding a listener to the router and updating SystemNavigator.setFrameworkHandlesBack.~~
Similar to with nested Navigators, nested go_routers is supported by using a PopScope widget.

A widget was added to explicitly and intentionally overlap the
PlatformView so that the rendering tree of Views would always have an
underlay and an overlay to match the test expectations.
Deprecate `textScaleFactor` in favor of `textScaler`, in preparation for Android 14 [Non-linear font scaling to 200%](https://developer.android.com/about/versions/14/features#non-linear-font-scaling). The `TextScaler` class can be moved to `dart:ui` in the future, if we decide to use the Android platform API or AndroidX to get the scaling curve instead of hard coding the curve in the framework.
I haven't put the Flutter version in the deprecation message so the analyzer checks are failing. Will do so after I finish the migration guide.
**Why `TextScaler.textScaleFactor`**
The author of a `TextScaler` subclass should provide a fallback `textScaleFactor`. By making `TextScaler` also contain the `textScaleFactor` information it also makes it easier to migrate: if a widget overrides `MediaQueryData.textScaler` in the tree, for unmigrated widgets in the subtree it would also have to override `MediaQueryData.textScaleFactor`, and that makes it difficult to remove `MediaQueryData.textScaleFactor` in the future.
## A full list of affected APIs in this PR
Deprecated: The method/getter/setter/argument is annotated with a `@Deprecated()` annotation in this PR, and the caller should replace it with `textScaler` instead. Unless otherwise specified there will be a Flutter fix available to help with migration but it's still recommended to migrate case-by-case.
**Replaced**: The method this `textScaleFactor` argument belongs to is rarely called directly by user code and is not overridden by any of the registered custom tests, so the argument is directly replaced by `TextScaler`.
**To Be Deprecated**: The method/getter/setter/argument can't be deprecated in this PR because a registered customer test depends on it and a Flutter fix isn't available (or the test was run without applying flutter fixes first). This method/getter/setter/argument will be deprecated in a followup PR once the registered test is migrated.

A lot of material widgets (`Slider`, `RangeSlider`, `TimePicker`, and different types of buttons) also change their layout based on `textScaleFactor`. These need to be handled in a case-by-case fashion and will be migrated in follow-up PRs.
This change enables Flutter to generate multiple Scenes to be rendered into separate FlutterViews from a single widget tree. Each Scene is described by a separate render tree, which are all associated with the single widget tree.
This PR implements the framework-side mechanisms to describe the content to be rendered into multiple views. Separate engine-side changes are necessary to provide these views to the framework and to draw the framework-generated Scene into them.
## Summary of changes
The details of this change are described in [flutter.dev/go/multiple-views](https://flutter.dev/go/multiple-views). Below is a high-level summary organized by layers.
### Rendering layer changes
* The `RendererBinding` no longer owns a single `renderView`. In fact, it doesn't OWN any `RenderView`s at all anymore. Instead, it offers an API (`addRenderView`/`removeRenderView`) to add and remove `RenderView`s that then will be MANAGED by the binding. The `RenderView` itself is now owned by a higher-level abstraction (e.g. the `RawView` Element of the widgets layer, see below), who is also in charge of adding it to the binding. When added, the binding will interact with the `RenderView` to produce a frame (e.g. by calling `compositeFrame` on it) and to perform hit tests for incoming pointer events. Multiple `RenderView`s can be added to the binding (typically one per `FlutterView`) to produce multiple Scenes.
* Instead of owning a single `pipelineOwner`, the `RendererBinding` now owns the root of the `PipelineOwner` tree (exposed as `rootPipelineOwner` on the binding). Each `PipelineOwner` in that tree (except for the root) typically manages its own render tree typically rooted in one of the `RenderView`s mentioned in the previous bullet. During frame production, the binding will instruct each `PipelineOwner` of that tree to flush layout, paint, semantics etc. A higher-level abstraction (e.g. the widgets layer, see below) is in charge of adding `PipelineOwner`s to this tree.
* Backwards compatibility: The old `renderView` and `pipelineOwner` properties of the `RendererBinding` are retained, but marked as deprecated. Care has been taken to keep their original behavior for the deprecation period, i.e. if you just call `runApp`, the render tree bootstrapped by this call is rooted in the deprecated `RendererBinding.renderView` and managed by the deprecated `RendererBinding.pipelineOwner`.
### Widgets layer changes
* The `WidgetsBinding` no longer attaches the widget tree to an existing render tree. Instead, it bootstraps a stand-alone widget tree that is not backed by a render tree. For this, `RenderObjectToWidgetAdapter` has been replaced by `RootWidget`.
* Multiple render trees can be bootstrapped and attached to the widget tree with the help of the `View` widget, which internally is backed by a `RawView` widget. Configured with a `FlutterView` to render into, the `RawView` creates a new `PipelineOwner` and a new `RenderView` for the new render tree. It adds the new `RenderView` to the `RendererBinding` and its `PipelineOwner` to the pipeline owner tree.
* The `View` widget can only appear in certain well-defined locations in the widget tree since it bootstraps a new render tree and does not insert a `RenderObject` into an ancestor. However, almost all Elements expect that their children insert `RenderObject`s, otherwise they will not function properly. To produce a good error message when the `View` widget is used in an illegal location, the `debugMustInsertRenderObjectIntoSlot` method has been added to Element, where a child can ask whether a given slot must insert a RenderObject into its ancestor or not. In practice, the `View` widget can be used as a child of the `RootWidget`, inside the `view` slot of the `ViewAnchor` (see below) and inside a `ViewCollection` (see below). In those locations, the `View` widget may be wrapped in other non-RenderObjectWidgets (e.g. InheritedWidgets).
* The new `ViewAnchor` can be used to create a side-view inside a parent `View`. The `child` of the `ViewAnchor` widget renders into the parent `View` as usual, but the `view` slot can take on another `View` widget, which has access to all inherited widgets above the `ViewAnchor`. Metaphorically speaking, the view is anchored to the location of the `ViewAnchor` in the widget tree.
* The new `ViewCollection` widget allows for multiple sibling views as it takes a list of `View`s as children. It can be used in all the places that accept a `View` widget.
## Google3
As of July 5, 2023 this change passed a TAP global presubmit (TGP) in google3: tap/OCL:544707016:BASE:545809771:1688597935864:e43dd651
## Note to reviewers
This change is big (sorry). I suggest focusing the initial review on the changes inside of `packages/flutter` first. The majority of the changes describe above are implemented in (listed in suggested review order):
* `rendering/binding.dart`
* `widgets/binding.dart`
* `widgets/view.dart`
* `widgets/framework.dart`
All other changes included in the PR are basically the fallout of what's implemented in those files. Also note that a lot of the lines added in this PR are documentation and tests.
I am also very happy to walk reviewers through the code in person or via video call, if that is helpful.
I appreciate any feedback.
## Feedback to address before submitting ("TODO")
Manual roll is needed because incoming dart sdk requires updated version

they continue to pass when the default for `ThemeData.useMaterial3` is
changed to true.
This is the final set of changes required for
https://github.com/flutter/flutter/issues/127064.
- Bumps `vm_service` from `11.6.0` to `11.7.1`
- Bumps `web` from `0.1.3-beta` to `0.1.4-beta` and adds it everywhere.
- Moves `js` from `dependencies` to `dev_dependencies`
Unpins flutter_plugin_android_lifecycle where it is pinned. I then
1. ran `flutter update-packages --force-upgrade` (but only committed the changes within `dev/integration_tests/gradle_deprecated_settings/`, which is where it had been pinned)
2. followed by `./gradlew :generateLockfiles` from `dev/integration_tests/gradle_deprecated_settings/android/` (the lockfile was what was causing the CI dependency resolution failure, so this second step is the fix for that).
See the reason it was pinned: https://github.com/flutter/flutter/pull/121847#discussion_r1124797112 followed by the PR that pinned it: https://github.com/flutter/flutter/pull/122043
Fixes https://github.com/flutter/flutter/issues/122039
Fixes#124252, finishing work on the umbrella tracking issue, #126126.
Essentially, after this PR, no (non-test) code should be be referencing/invoking the java home or binary paths.
I think the flake is due to setclipboard or semantics update race condition. I migrated the test to use integration test package which relies less on timing
fixes https://github.com/flutter/flutter/issues/124636
## 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.

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`.

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.
Most of these imports were never appropriate. The `test_api` package was never intended for use in `_test.dart` files.
Where possible move imports to `matcher`, otherwise move them to `test` or `flutter_test`.
Leave uses of `test_api` from `flutter_test` library code.
- Update gradle and AGP version for abstract_method_smoke_test
#125138 part 1/N
To update successfully:
1. Update gradle to a version supported by jdk 17
2. Uncommented the lockfile lines in android/build.gradle
3. Then ran the AGP update assistant from AndroidStudio -> tools
4. From android ran `./gradlew dependencies --write-locks`
5. From android/app ran `./gradlew dependencies --write-locks`
6. Re enabled the lockfiles section of android/build.gradle
7. Ensured `flutter build apk` passed

Doc covering a broad set of issues related to android studio updating.
https://docs.google.com/document/d/1hTXkjbUrBnXgu8NQsth1c3aEqo77rWoEj8CcsQ39wwQ/edit?pli=1#
Specifically this pr:
- Adds new functions to find a projects AGP, Gradle and java versions,
and tests.
- Adds new functions that take versions and parse if the versions are
compatible with each other, and tests.
- Adds validator for `flutter analyze --suggestions` that evaluates the
java/gradle/agp versions and checks if they are compatible, and
integration test.
- Updates the version of gradle used by
dev/integration_tests/flutter_gallery/ to the minimum supported by java
18 so that the integration tests pass (It is unknown why the java
version is 18.9 instead of 11)
- Moves `isWithinVersionRange` to version.dart, and tests.
- Adds FakeAndroidStudio to fakes to be used in multiple tests but does
not remove existing copies.
Metrics will be included as part of the definition of done for this bug
but not as part of this cl. It is already too big.
Known work still left in this pr:
* Understand why analyze integration tests are failing.
