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.
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.

~Still a WIP while I clean up some error handling, remove some prints, and figure out a Java test (more difficult than the others because I believe we can only install one java version per ci shard).~
~Also it looks like there are errors that I need to fix when this checking is applied to a project that uses the old way of applying AGP/KGP using the top-level `build.gradle` file (instead of the new template way of applying them in the `settings.gradle` file).~ Done, this is why [these lines exist](9af6bae6b9/packages/flutter_tools/gradle/src/main/groovy/flutter.groovy (L72-L88)) in `flutter.groovy`. They just needed to be added
Add a new `BuildTargets` class that provides commonly used build targets. And avoid importing files from `build_system/targets` except from the top level entrypoints or from top level commands.
Also move `scene_importer.dart` and `shader_compiler.dart` into `build_system/tools` because they are not `Target` classes, but wrapper for certain tools.
With this change, we can ignore all files in `build_system/targets` internally and make PR #142709 easier to land internally. See cl/603434066 for the corresponding internal change.

Also note that I have opted to add a new variable in `globals.dart` for `BuildTargets` in this PR, but I know that we are trying to get rid of globals. Several alternatives that I was considering:
1. Add a new field in `BuildSystem` that returns a `BuildTargets` instance. Since `BuildSystem` is already in `globals`, we can access build targets using `globals.buildSystem.buildTargets` without adding a new global variable.
2. Properly inject the `BuildTargetsImpl` instance from the top level `executable.dart` and top level commands.
Let me know if you want me to do one of the above instead. Thanks!
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.
When the Dart VM is not found within 10 minutes in CI on CoreDevices (iOS 17+), stop the app and upload the logs from DerivedData. The app has to be stopped first since the logs are not put in DerivedData until it's stopped.
Also, rearranged some logic to have CoreDevice have its own function for Dart VM url discovery.

This PR increases Android's `minSdkVersion` to 21.
There are two changes in this PR aside from simply increasing the number
from 19 to 21 everywhere.
First, tests using `flutter_gallery` fail without updating the
lockfiles. The changes in the PR are the results of running
`dev/tools/bin/generate_gradle_lockfiles.dart` on that app.
Second, from
[here](https://developer.android.com/build/multidex#mdex-pre-l):
> if your minSdkVersion is 21 or higher, multidex is enabled by default
and you don't need the multidex library.
As a result, the `multidex` option everywhere is obsolete. This PR
removes all logic and tests related to that option that I could find.
`Google testing` and `customer_tests` pass on this PR, so it seems like
this won't be too breaking if it is at all. If needed I'll give this
some time to bake in the framework before landing the flutter/engine
PRs.

It's now possible to natively compile a flutter app for windows-arm64. Cross-compilation is not yet implemented.
Uses arm64 artifacts now available for Dart/Flutter. Platform detection is based on Abi class, provided by Dart. Depending if Dart is an arm64 or x64 binary, the Abi is set accordingly. Initial bootstrap of dart artifacts (update_dart_sdk.ps1) is checking PROCESSOR_ARCHITECTURE environment variable, which is the way to detect host architecture on Windows.
This is available only for master channel (on other channels, it fallbacks to windows-x64).
On windows-x64, it produces an x64 app. On windows-arm64, it produces an arm64 app.

- https://github.com/flutter/flutter/issues/128251
This PR includes 3 major updates:
- Adding the `commandHasTerminal` parameter for `Event.flutterCommandResult`
- In `packages/flutter_tools/lib/src/runner/flutter_command.dart`
- Adding the new event for `sendException` from package:usage to be `Event.exception` (this event can be used by all dash tools)
- In `packages/flutter_tools/lib/runner.dart`
- Migrating the generic `UsageEvent` which was only used for Apple related workflows for iOS and macOS. I did an initial analysis in this [sheet](https://docs.google.com/spreadsheets/d/11KJLkHXFpECMX7tw-trNkYSr5MHDG15XNGv6TgLjfQs/edit?resourcekey=0-j4qdvsOEEg3wQW79YlY1-g#gid=0) to identify all the call sites
- Found in several files, highlighted in the sheet above

This event was only called from one file (`flutter_command.dart`). With the previous implementation, we actually sent 2 events, one for the result of the `commandPath` and another containing the `maxRss` value from `ProcessInfo`.
I have consolidated this down to just one event and used a function to safely get the `maxRss` value, or return null when if there was an error getting that integer value

Without this, if a user runs an app that has plugins that call method channels with the `preview` device, the app will build successfully, however, they will get a runtime error when their dart code tries to call the method channel that does not exist in the native build (which was pre-built and thus does not include the plugin code).
This change adds a validation when injecting plugins that will tool exit if the device-id is `preview` and their project contains plugins with method channels.
Fixes https://github.com/flutter/flutter/issues/134279.
Changes:
* Moves all tests of `--dart-define-from-file` behavior from `build_bundle_test.dart` and `assemble_test.dart` to `flutter_command_test.dart`.
* Deletes a duplicate test of malformed JSON detection behavior.
* Renames the `useDartDefineFromFileOption` method of `FlutterCommand` to `_usesDartDefineFromFileOption`. This 1) makes the name more consistent with the other `uses*Option` methods and 2) hides the method since it is not used outside of the file.
* Renames several tests to better articulate what is under test and what the expected result is.
* Adds a test for the case where a `.env` file with a malformed line is provided to `--dart-define-from-file`.
Adds support for a new --web-header option to flutter run.
Creates a workaround for https://github.com/flutter/flutter/issues/127902
This PR allows adding additional headers for the flutter run web server. This is useful to add headers like Cross-Origin-Embedder-Policy and Cross-Origin-Opener-Policy without the use of a proxy server. These headers are required enable advanced web features. This approach provides flexibility to the developer to make use of the feature as they see fit and is backward-compatible. One tradeoff is that it increases the surface area to support for future changes to the flutter web server.
https://github.com/flutter/flutter/issues/127902 is not fully addressed by this change. The solution for that task will be more opinionated. This PR creates a general-purpose workaround for anyone who needs a solution sooner while the bigger solution is developed.
Resolves#128046.
Adds a services API that allows flutter app developers to write app code that determines `--flavor` the app was built with.
This is implemented by having the tool adding the value of `--flavor` to its list of dart environment declarations, which will be available to the app at run time. Specifically,`FLUTTER_APP_FLAVOR` is set. I chose this implementation for its simplicity. There is some precedent for this, but only for web ([example](cd2f3f5e78/packages/flutter_tools/lib/src/runner/flutter_command.dart (L1231))).
Remove double.fromEnvironment from dart-define doc.
Fixes#124665
The current dart-define docs reads:
```
Additional key-value pairs that will be available as constants from the String.fromEnvironment, bool.fromEnvironment, int.fromEnvironment, and
double.fromEnvironment constructors.
```
while dart-define-from-file reads:
```
The path of a json format file where flutter define a global constant pool.
Json entry will be available as constants from the String.fromEnvironment, bool.fromEnvironment, int.fromEnvironment,
and double.fromEnvironment constructors; the key and field are json values
```
