* Fix expression evaluation test leaking flutter_tester processes.
Let flutter_tester process complete, wait for it completion, kill the test only if didn't complete on time.
* Type annotation
* 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
* Resume isolate before terminating tests to prevent flutter_tester leak
* Fix lint
* Catch exceptions from resume() as well as timeout()
* Formatting fixes
* Don't try to resume if there's no vm service
* Fix handling of timeouts to not leak futures
Plus:
- Resume the app being run after expression has been evaluated to prevent the test run being forcefully terminated because it didn't end
- Skip non-JSON when waiting for JSON (eg. when running in verbose mode for debugging locally)
- Pass defaultTimeout in waitForJson (otherwise the assert in _timeoutWithMessages fails when it's not provided)
Closes https://github.com/flutter/flutter/issues/26518 (the original reason for skip was fixed in https://github.com/dart-lang/sdk/issues/34224).
