Some runs of DeviceLab performance tests are run without a gitBranch option, but
still must save their results to a local file.

(Attempt to reland #85993)

This reverts commit 2175e64e.

Migrate core devicelab framework to null safety.

This reverts commit 297c7b5c.

This reverts commit 9d1d0cfe.

Remove devicelab specific code for shutting down gradle daemon, add --android-gradle-daemon option to build/run/drive`. Avoids need for un-tested devicelab specific handler. There are also some feature requests for this, so 2 birds one stone.

Example:

flutter build apk --no-android-gradle-daemon will pass --no-daemon on to gradle

This reverts commit ddab72e7.

This crash affects anyone using flutter, so move it into the tool where it can be tested and documented. Ensure it works on windows devicelab too.

This is a workaround for https://github.com/flutter/flutter/issues/62139
so that the engine roll pipeline can proceed.

* Implement device selection for devicelab/run.dart

* Add test to --device-id option for devicelab/run

* Update dev/devicelab/bin/run.dart by jonahwilliam

* Rename deviceOperatingSystem enum mock -> fake

This reverts commit 283ec9e2.

* 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

Revert "replace package:vm_service_client with package:vm_service in the devicelab project (#41646)" (#41960)

* Added support for authentication codes for the VM service.

Previously, a valid web socket connection would use the following URI:

`ws://127.0.0.1/ws`

Now, by default, the VM service requires a connection to be made with a
URI similar to the following:

`ws://127.0.0.1:8181/Ug_U0QVsqFs=/ws`

where `Ug_U0QVsqFs` is an authentication code generated and shared by
the
service.

This behavior can be disabled with the `--disable-service-auth-codes`
flag.

This reverts commit 19d6e7b6.

This renames the "module" template to the "application" template, and makes "application" the default. The existing "app" template is now deprecated.

flutter create also now recognizes the type of project in an existing directory, and is able to recreate it without having the template type explicitly specified (although you can still do that). It does this now by first looking in the .metadata file for the new project_type field, and if it doesn't find that, then it looks at the directory structure. Also, the .metadata file is now overwritten even on an existing directory so that 1) the project_type can be added to legacy projects, and 2) the version of Flutter that updated the project last is updated.

I also cleaned up a bunch of things in create_test.dart, added many more tests, and added an example test to the test/ directory in the generated output of the application template.
