* opt out the flutter tool

* oops EOF

* fix import

* Update tool_backend.dart

* Update daemon_client.dart

* fix more

* Launch DevTools from pub instead of devtools_server

* Move web integration tool tests to web.shard

Web integration tool tests depend on DDC changes in SDK. This change
moves them to a separate shard and subshard so CI bot configurations
can run them separately.

In particular, with will allow running those tests on dart CI flutter
HHH web bot instead of a non-web one, allowing early detection and easy
classification of issues caused by SDK changes as VM- or Web related.

* Enabled verbose mode for flaky web_tool_tests

* fixed local engine crash with --enable-asserts

* Disable failing tests, fix local engine with asserts

* Removed mac web_tool_tests bot

* Addressed CR comments

* Add disabled mac web_tool_tests and disable win web_tool_tests

Support --web-renderer options which would allow user to specify which rendering backend to use. (#68848)

* Add punctuation for unterminated sentences in doc comments

* Addressing review nit

In web debug mode, infer sound null safety by default. When sound null safety is enabled, provide a separate dill and precompiled Dart SDK. Release builds do not need this setting since we run dart2js from source.

Fixes #59873

Revert "[flutter_tools] separate target platform, host platform, and architecutre (#60119)" (#60147)

This reverts commit 30d97d89.

separate target platform, host platform, and architecture

Refactors KernelCompiler and ResidentCompiler to no longer use globals (except as a fallback for g3 migration). Improves the compilation error when running flutter test on a package without a flutter_test dependency.

Updates machine mode to output trace text to stderr

Updates the tooling to use the GTK embedding, rather than the GLFW embedding:
- Adds new requirements to `doctor`
- Updates the app and plugin templates to make GTK-based runners and plugins
- Stops downloading and installing the GLFW artifacts

Final part of #54860, other than cleanup.

flutter analyze was unconditionally using the cached dart-sdk for analysis, and was not running with the built SDK during local engine. This broke when trying to update the analyzer for null safety, since it required us to wait for the dart change to roll into the framework first.

This reverts commit 9ed3e5be.

Builds and bundles an 'app.so' containing AOT data, and downloads and packages the release/profile artifacts for those builds, rather than always using the debug artifacts.

To simplify development of the in-progress GTK embedding, which will
replace the GLFW embedding on Linux, add the GTK artifacts to the unpack
list. This means that until the transition, both the GLFW and GTK
artifacts will be unpacked.

Part of #54860

- Update windows precache to include placeholder profile/release artifacts
- Update Linux and windows unpack to account for the cpp_client_wrapper code to live separate from the engine binaries
- Cleanup testing in unpack_linux and remove test cases that are covered in build_system_test.dart

* Update project.pbxproj files to say Flutter rather than Chromium

Also, the templates now have an empty organization so that we don't cause people to give their apps a Flutter copyright.

* Update the copyright notice checker to require a standard notice on all files

* Update copyrights on Dart files. (This was a mechanical commit.)

* Fix weird license headers on Dart files that deviate from our conventions; relicense Shrine.

Some were already marked "The Flutter Authors", not clear why. Their
dates have been normalized. Some were missing the blank line after the
license. Some were randomly different in trivial ways for no apparent
reason (e.g. missing the trailing period).

* Clean up the copyrights in non-Dart files. (Manual edits.)

Also, make sure templates don't have copyrights.

* Fix some more ORGANIZATIONNAMEs

* Reland: [flutter_tool] Fuchsia AOT builds

* Fixes
