Updates Gradle version for Flutter project templates and integration tests to at least 7.6.3 (changed all of those with versions below it) to fix security vulnerability.
Part of fix for https://github.com/flutter/flutter/issues/138336.
Upgrades agp versions and lockfiles for `dev/`. Also changes the lockfile generation script to represent the newer form of the `settings.gradle` template, and therefore also propagates these changes.
~~Potentially related to https://github.com/flutter/flutter/issues/134419~~, but worth doing anyways. (not actually related)
Addresses #63507, and is a follow up to the engine PR https://github.com/flutter/engine/pull/46857
Changes the font family string when attempting to use Apple system fonts to the new proxies added by the engine. For the "Text" font this will be more secure in the future against possible changes to Apple's API. For the "Display" font, this will now work correctly when it didn't before.
I checked the letter spacing values against a native app for all font sizes between 17-28. I made a few adjustments to better match native, but especially for the "Text" font we were either really close, or close enough to not make a large breaking change to default fonts worth it.

The smaller text in both the before and after should be the same. The large system font that Flutter used before was incorrect, which caused it to look more spread out. Now we use the correct font.
I previously made a PR (#136140) that used `switch` expressions to make some parts of the Flutter codebase easier to understand. It was assigned to the framework team, and @christopherfujino let me know that it was too large to effectively review and recommended breaking it up into smaller pull requests.
Here's a PR that only targets files in the `dev/` directory. Hopefully this will be easier to work with!
(solves issue https://github.com/flutter/flutter/issues/136139)
This version is needed so that dart:js_interop can move to extension
types. Also adds some code to handle some breaking changes:
- Body -> Response. Body was an IDL interface mixin type we exposed in
dart:html. Going forward, users should either use Request or Response.
- Casts to JSAny. These are temporary until we move package:web types to
extension types. Currently, package:web types can't implement JSObject
as JSObject will move to be an extension type itself.

Original Description:
Adds support for Android 34 in the following ways:
- Bumps integration tests compile SDK versions 33 --> 34
- Bumps template compile SDK version 33 --> 34
- Also changes deprecated `compileSdkVersion` to `compileSdk`

Fixes in preparation for https://dart-review.googlesource.com/c/sdk/+/330561.
The change referenced above tightens the `use_build_context_synchronously` to ensure that `mounted` is checked on the appropriate `BuildContext` or `State`. This change fixes up the flutter/flutter in preparation of this new enforcement.
Analyzer's dependency on autosnapshotting causes issues.
Because every version of integration_test from sdk depends on leak_tracker from hosted and autosnapshotting depends on leak_tracker from path, integration_test from sdk is forbidden.
So, because autosnapshotting depends on integration_test from sdk, version solving failed.
This enables our various date picker classes to have a null `initialDate`.
It also fixes the logic of some of the widgets which used to do something when you _changed_ the `initial*` parameters, which is wrong for `initial*` properties (they by definition should only impact the initial state) and wrong for properties in general (behaviour should not change based on whether the widget was built with a new value or not, that violates the reactive design principles).
Fixes https://github.com/flutter/flutter/issues/638.
* Pulled `FinderBase` out of `Finder`
* `FinderBase` can be used for any object, not just elements
* Terminology was updated to be more "find" related
* Re-implemented `Finder` using `FinderBase<Element>`
* Backwards compatibility maintained with `_LegacyFinderMixin`
* Introduced base classes for SemanticsNode finders
* Introduced basic SemanticsNode finders through `find.semantics`
* Updated some relevant matchers to make use of the more generic `FinderBase`
Closes#123634Closes#115874
Implement expected functionalities when supplying `--web-launch-url` and/or `--web-hostname` arguments to `flutter drive`.
- `--web-launch-url` now sets the starting url for the (headless) browser
- Which for example means you can start at a certain part of the app at the start of your integration test
- `--web-hostname` now sets the hostname where the target of flutter drive will be hosted
- Which allows you to set something other than localhost (allowing access via a reverse-proxy for example)
Fixes#118028
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.
