This change adds the following events:
- `widget_preview.initializing`: sent immediately after the widget
previewer starts. This event includes the PID of the process starting
the widget previewer for use by tooling to explicitly kill the tool
process.
- `widget_preview.logMessage`: sent for calls to `Logger` methods when
in machine mode. This follows the same format as `daemon.logMessage`.
This change also fixes and improves testing of
`WidgetPreviewMachineAwareLogger` in `widget_preview_machine_test.dart`
as the existing test validator did not cause tests to fail correctly.
Fixes https://github.com/flutter/flutter/issues/175002
Closes https://github.com/flutter/flutter/issues/74165.
The original issue called for, on Windows, telling `CYGWIN` to use
`=noglob`, to work around some git operation errors that happen when
using non-native Git. There ... was no great way to do this with the
existing codebase without, IMO, adding lots of confusing code.
So, I refactored all the calls of:
- before: `processUtils.<method>(['git', ...args], ...params)`
- after: `git.<method>([...args], ...params)`
... and implicitly add the new environment variables, if
`Platform.isWindows`.
Did some minor test cleanup and process execution cleanup while I was at
it.
Sources under `packages/flutter_tools/` aren't accessible to the average
Flutter user by navigating through sources from their projects, so it
doesn't need to be as explicitly verbose with types for readability
purposes. The `always_specify_types` lint results in extremely verbose
code within the tool which adds little value.
This change disables `always_specify_types` in favor of a new set of
lints that aim to reduce verbosity by removing obvious types while also
maintaining readability in cases where variable types otherwise wouldn't
be obvious:
- `omit_obvious_local_variable_types`
- `omit_obvious_property_types`
- `specify_nonobvious_local_variable_types`
- `specify_nonobvious_property_types`

Switch Flutter to use pub workspaces as a preparation to unpin selected
packages.
Assumptions:
1. No packages in this repository are published to pub.dev --> We can
use `any` dependencies in most local pubspecs, as the global constraint
defines the version. An exception are the packages used outside of this
repo with an `sdk` dependency, namely `flutter_localizations`,
`flutter_test`, and `flutter`.
2. The "universes" `{flutter_tools}` and `{flutter,
flutter_localizations, flutter_goldens}` can use different packages
versions, as they are not resolved together. --> We do not need to
upgrade them in sync, we can first do one "universe", then the other.
Based on these assumptions, we use
https://github.com/mosuem/pubspec_merger.dart to merge all packages in
the `flutter` universe into a top-level pub workspace.
The `flutter` and `flutter_tools` workspaces being separate also ensures
that changes to `flutter` will not inadvertently break `flutter_tools`,
with not-so-nice consequences for our users which would be unable to run
`flutter upgrade`.
There is a third "top-level" pubspec besides `./pubspec.yaml` and
`packages/flutter_tools/pubspec.yaml`, namely
`packages/flutter_tools/.../widget_preview_scaffold/pubspec.yaml`. This
is an artifact due to it living under `flutter_tools`, so it can't be
part of the `./pubspec.yaml` workspace. Moving it would be a larger
change, and out of the scope of this PR.
This required a rewrite of the update-packages tool, but the main
functionality stays the same, as well as the argument names, to ensure a
seamless transition.

This PR makes the following improvements to web hot reload support and
related tests:
- The `--start-paused` flag is now silently added when running with `-d
web-server --web-experimental-hot-reload` if it is not already present.
- Refactored test infrastructure to allow specifying the device
parameter (e.g., `'chrome'`, `'web-server'`) when running integration
tests.
- Added a new `web_run_web_server_test` to run flows on the web-server
device.
- Updated existing tests to explicitly pass the correct device parameter
where needed.
- We are currently not able to test hot reload on the web-server device
as this is not yet supported.

This reverts commit 059326d49dcdf8aca1ddbe755cdb337059fe5b21 and updates

Fixes#166417
- Adds better instructions for hot reload (if using the right flags),
hot restart, quitting, clearing, and more. These were already being
printed when using the VM, so this aligns with that.
- Adds an extra parameter for `CommandHelp` to `ResidentRunner` so
`ResidentWebRunner` can pass a version of it that uses its separate
logger and not `globals`. In order to support this, classes up the stack
also provide a `Terminal`, `Platform`, and `OutputPreferences`.
- Fixes up use of `globals` from an earlier change to implement hot
reload to use the logger instead. Same with `globals.platform`.
- Adds tests to check that only hot restart is printed when not using
the extra front-end flags, and both hot restart and hot reload is
printed when you are.

This also wires up the preview detector to trigger hot reloads when new
previews are detected or previews are removed.
Note: while this change results in lib/generated_preview.dart being
generated and updated, it's not currently referenced by lib/main.dart
and the preview environment will render a black screen.

This auto-formats all *.dart files in the repository outside of the

a presubmit check.
**Reviewers:** Please carefully review all the commits except for the
one titled "formatted". The "formatted" commit was auto-generated by
running `dev/tools/format.sh -a -f`. The other commits were hand-crafted
to prepare the repo for the formatting change. I recommend reviewing the

This is the initial tooling work for Flutter Widget Previews, adding two
commands: `flutter widget-preview start` and `flutter widget-preview
clean`.
The `start` command currently only checks to see if
`.dart_tool/widget_preview_scaffold/` exists and creates a new Flutter
project using the widget_preview_scaffold template if one isn't found.
The widget_preview_scaffold template currently only contains some
placeholder files and will be updated to include additional code
required by the scaffold.
The `clean` command simply deletes `.dart_tool/widget_preview_scaffold/`
if it's found.
This change also includes some refactoring of the `create` command in
order to share some project creation logic without requiring `flutter
widget-preview start` to spawn a new process simply to run `flutter
create -t widget_preview .dart_tool/widget_preview_scaffold`.

This PR introduces a `NativeAssetsManifest.json` next to the
`AssetManifest.bin` and `FontManifest.json`. This removes the need for
embedding the native assets mapping inside the kernel file and enables
decoupling native assets building and bundling from the kernel
compilation in flutter tools. This means `flutter run` no longer does a
dry run of `hook/build.dart` hooks.
(It also means all isolate groups will have the same native assets.
However, since Flutter does not support `Isolate.spawnUri` from kernel
files, this is not a regression.)
Implementation details:
* g3 is still using kernel embedding.
https://github.com/flutter/flutter/pull/142016 introduced an argument to
embed a `native_assets.yaml` inside `flutter attach` and `flutter run`
(the outer flutter process), but it is not used in `flutter assemble`
(the inner process when doing `flutter run`). So, those arguments need
to still be respected. However, all other logic related to embedding a
yaml encoding in the kernel file has been removed.
* All dry-run logic has been removed. 🎉
* The `KernelSnapshot` target no longer depends on the
`InstallCodeAssets` target. Instead, the various OS-specific
"BundleAsset" targets now depend on the `InstallCodeAssets` target. The
`InstallCodeAssets` invokes the build hooks and produces the
`NativeAssetsManifest.json`. The various "BundleAsset" commands
synchronize the `NativeAssetsManifest.json` to the app bundle.
* `InstallCodeAssets` produces a `native_assets.json`, which is renamed
to `NativeAssetsManifest.json` in the various "Bundle" targets. This
means that all unit tests of the "Bundle" targets now need to create
this file. (Similar to how `app.dill` is expected to exist because
`KernelSnapshot` is a dependency of the "Bundle" targets.)
* Because dynamic libraries need to be code signed (at least on iOS and
MacOS), the bundling of the dylibs is _not_ migrated to reuse
`_updateDevFS` (which is used for ordinary assets). Only the 2nd and 3rd
invocation of `flutter assemble` from `xcodebuild` has access to the
code signing identity.
Relevant tests:
* test/integration.shard/isolated/native_assets_test.dart - runs
`flutter run` with native assets including hot restart and hot reload.
TODO:
* Undo engine-roll in this PR after engine has rolled in.

Native libraries that are contributed by native asset builders can depend on each other. For macOS and iOS, native libraries are repackaged into Frameworks, which renders install names that have been written into dependent libraries invalid.
With this change, a mapping between old and new install names is maintained, and install names in dependent libraries are rewritten as a final step.

Reland of https://github.com/flutter/flutter/pull/142709.
The revert of the revert is in the first commit, the fix in the commit on top.
The move of the fakes for packages/flutter_tools/test/general.shard/resident_runner_test.dart was erroneous before, as it was trying to use setters instead of a private field. This PR changes the private `_devFS` field in the fake to be a public `fakeDevFS` in line with other fakes.
## Original PR description
Native assets in other build systems are not built with `package:native_assets_builder` invoking `build.dart` scripts. Instead all packages have their own blaze rules. Therefore we'd like to not depend on `package:native_assets_builder` from flutter tools in g3 at all.
This PR aims to move the imports of `native_assets_builder` and `native_assets_cli` into the `isolated/` directory and into the files with a `main` function that are not used in with other build systems.
In order to be able to remove all imports in files used by other build systems, two new interfaces are added `HotRunnerNativeAssetsBuilder` and `TestCompilerNativeAssetsBuilder`. New parameters are then piped all the way through from the entry points:
* bin/fuchsia_tester.dart
* lib/executable.dart
The build_system/targets dir is already excluded in other build systems.
So, after this PR only the two above files and build_system/targets import from `isolated/native_assets/` and only `isolated/native_assets/` import `package:native_assets_cli` and `package:native_assets_builder`.

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!

1. introduce a hidden `flutter build _preview` command, that will build a debug windows desktop app and copy it into the SDK's binary cache. This command is only intended to be run during packaging.
2. introduce a new device type, called `PreviewDevice`, which relies on the prebuilt desktop debug app from step 1, copies it into the target app's assets build folder, and then hot reloads their dart code into it.

Before this change, there were two places we overrode the `Artifacts` in a Zone:
1. if/when we parse local-engine CLI options: 1cf3907407/packages/flutter_tools/lib/src/runner/flutter_command_runner.dart (L281)
2. an additional override for fuchsia platform dill (no longer used, deleted in this PR): 1cf3907407/packages/flutter_tools/lib/src/commands/attach.dart (L274)
Note 1 above creates a new instance of `Artifacts.getLocalEngine()`. In this flow, there exist two instances of `Artifacts`:
1. The default fallback instance of `CachedArtifacts` (which gets all artifacts from flutter/bin/cache), instantiated in context_runner.dart: 1cf3907407/packages/flutter_tools/lib/src/context_runner.dart (L137)
2. An instance of `CachedLocalEngineArtifacts` created in the command runner once the CLI options have been parsed: 1cf3907407/packages/flutter_tools/lib/src/runner/flutter_command_runner.dart (L281)
The regression happened when we direct injected the Artifacts 1 from above BEFORE we parsed the local-engine flag, and then used this in the second zone override, and then when creating the `FlutterDevice` there are multiple calls to `globals.artifacts` returned it when it should have returned Artifacts 2: 1cf3907407/packages/flutter_tools/lib/src/resident_runner.dart (L80)
Device.artifactOverrides was originally introduced in https://github.com/flutter/flutter/pull/32071, but is no longer used, so I deleted it.
I also removed direct injection of `Artifacts` to the attach sub-command, because that class now no longer references artifacts.
I believe the ideal true fix for this would be to:
1. Migrate all leaf calls to `globals.artifacts` to use direct injection (in this case, the offending invocations were in [`FlutterDevice.create()`](1cf3907407/packages/flutter_tools/lib/src/resident_runner.dart (L80-L218)), but I'm not sure that something else would not have broken later)
2. Ensure we are always direct injecting the desired instance of `Artifacts`--that is, if the user desires local engine artifacts, that we are passing an instance of `CachedLocalEngineArtifacts`.
a. Alternatively, and probably simpler, teach `CachedArtifacts` to know about the local engine. This would mean parsing the global CLI options BEFORE we ever construct any instance of `Artifacts`.
As an overall recommendation for implementing https://github.com/flutter/flutter/issues/47161, in the overall tree of tool function calls, we should probably migrate the leaves first (that is, migrate the sub-commands last). We should also audit and reconsider any usage of `runZoned()` or `context.run()` for the purpose overriding zoneValues.
You can now specify a --local-web-sdk flag to point to a wasm_release folder. This will make it so that only artifacts that pertain to the web sdk are overridden to point to the wasm_release folder. Other artifacts (such as impellerc) will pull from the cache, or from the --local-engine path if that is specified.
This also uses precompiled platform kernel files for both ddc and dart2js
