Original Description:
Reverts flutter/flutter#143973
This is a reland for #138521 with an updated g3fix(cl/605555997). Local test: cl/609608958.
This pull request fixes#143803 by taking advantage of Dart's null-aware operators.
And unlike `switch` expressions ([9 PRs](https://github.com/flutter/flutter/pull/143634) and counting), the Flutter codebase is already fantastic when it comes to null-aware coding. After refactoring the entire repo, all the changes involving `?.` and `??` can fit into a single pull request.
Entire pr generated with [ktlint](https://github.com/pinterest/ktlint) --format. First step before enabling linting as part of presubmit for kotlin changes.

We currently drop the first N frames of all benchmarks. For the app based benchmarks (not microbenchmarks) this is harmful as we miss first time initialization costs in our CI.
Still need to do this with flutter/gallery, but that lives in a different repo.
This is an attempt at a reland of https://github.com/flutter/flutter/pull/141396
The main changes here that are different than the original PR is fixes to wire up the `flutter test` command properly with the web renderer.
Dual Web Compile has had some issues where `flutter test` is not respecting the `--web-renderer` flag for some reason. I haven't gotten entirely to the bottom of the issue, but for now we need to rever these changes while I investigate. This reverts the following PRs:
https://github.com/flutter/flutter/pull/143128https://github.com/flutter/flutter/pull/141396
While doing this revert, I had a few merge conflicts with https://github.com/flutter/flutter/pull/142760, and I tried to resolve the merge conflicts within the spirit of that PR's change, but @chingjun I might need your input on whether the imports I have modified are okay with regards to the change you were making.
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.
Fixes: https://github.com/flutter/flutter/issues/134227
This PR updates almost* all Gradle buildscripts in the Flutter repo the `example` and `dev` (in particular, in `dev/integration_tests` and in `dev/benchmarks`) directories to apply Flutter's Gradle plugins using the declarative `plugins {}` block.
*almost, because:
- add-to-app (aka hybrid) apps are not migrated (related https://github.com/flutter/flutter/issues/138756)
- apps that purposefully use build files to ensure backward compatibility (e.g. [`gradle_deprecated_settings`](https://github.com/flutter/flutter/tree/3.16.0/dev/integration_tests/gradle_deprecated_settings))
This implements dual compile via the newly available flutter.js bootstrapping APIs for intelligent build fallback.
* Users can now use the `FlutterLoader.load` API from flutter.js
* Flutter tool injects build info into the `index.html` of the user so that the bootstrapper knows which build variants are available to bootstrap
* The semantics of the `--wasm` flag for `flutter build web` have changed:
- Instead of producing a separate `build/web_wasm` directory, the output goes to the `build/web` directory like a normal web build
- Produces a dual build that contains two build variants: dart2wasm+skwasm and dart2js+CanvasKit. The dart2wasm+skwasm will only work on Chrome in a cross-origin isolated context, all other environments will fall back to dart2js+CanvasKit.
- `--wasm` and `--web-renderer` are now mutually exclusive. Since there are multiple build variants with `--wasm`, the web renderer cannot be expressed via a single command-line flag. For now, we are hard coding what build variants are produced with the `--wasm` flag, but I plan on making this more customizable in the future.
* Build targets now can optionally provide a "build key" which can uniquely identify any specific parameterization of that build target. This way, the build target can invalidate itself by changing its build key. This works a bit better than just stuffing everything into the environment defines because (a) it doesn't invalidate the entire build, just the targets which are affected and (b) settings for multiple build variants don't translate well to the flat map of environment defines.
`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.

1. Move leak_tracker and leak_tracker_testing out of direct dependencies.
2. Move leak_tracker_flutter_testing from dev to prod dependencies for flutter_test
It is prerequisite for https://github.com/flutter/flutter/issues/135856
Pinning the package:web dependency constrains downstream packages from
using newer versions and making sure they support the version pinned in
Flutter. Since the usage of package:web in Flutter is light, we should
instead have a small shim like the engine and keep package:web as a dev
dependency only.
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)
This updates the implementation to use the stopwatch from the Clock object and pipes it through to the TestWidgetsFlutterBinding so it will be kept in sync with FakeAsync.
Relands https://github.com/flutter/flutter/pull/138843 attempted to reland https://github.com/flutter/flutter/pull/137381 which attempted to reland #132291
Fixes https://github.com/flutter/flutter/issues/97761
1. The original change was reverted due to flakiness it introduced in tests that use fling gestures.
* Using a mocked clock through the test binding fixes this now
2. It was reverted a second time because a change at tip of tree broke it, exposing memory leaks, but it was not rebased before landing.
* These leaks are now fixed
3. It was reverted a third time, because we were so excellently quick to revert those other times, that we did not notice the broken benchmark that only runs in postsubmit.
* The benchmark is now fixed
