* 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

* add trailing commas on list/map/parameters

* add trailing commas on Invocation with nb of arg>1

* add commas for widget containing widgets

* add trailing commas if instantiation contains trailing comma

* revert bad change

These are essentially self-inflicted race conditions. Instead of timeouts we're going to try a more verbose logging mechanism that points out when things are taking a long time.

This reverts commit 76f70810.

* Remove many timeouts.

These are essentially self-inflicted race conditions. Instead of timeouts we're going to try a more verbose logging mechanism that points out when things are taking a long time.

* Get the attach tests to pass.

* Apply review comments from Todd

* More review comment fixes

* Put back the extended timeouts here now that I know why we have them...

Fixes #22247.

* enable lint unnecessary_new

* fix tests

* fix tests

* fix tests

* Add --create option to flutter emulators

* Tweaks to error message

* Simplify emulator search logic

* Make name optional

* Add a note about this option being used with --create

* Tweaks to help information

* Switch to processManager for easier testing

* Don't crash on missing files or missing properties in Android Emulator

* Move name suffixing into emulator manager

This allows it to be tested in the EmulatorManager tests and also used by daemon later if desired.

* Pass the context's android SDK through so it can be mocked by tests

* Misc fixes

* Add tests around emulator creation

Process calls are mocked to avoid needing a real SDK (and to be fast). Full integration tests may be useful, but may require ensuring all build environments etc. are set up correctly.

* Simplify avdManagerPath

Previous changes were to emulatorPath!

* Fix lint errors

* Fix incorrect file exgtension for Windows

* Fix an issue where no system images would crash

reduce throws on an empty collection.

* Fix "null" appearing in error messages

The name we attempted to use will now always be returned, even in the case of failure.

* Add additional info to missing-system-image failure message

On Windows after installing Andriod Studio I didn't have any of these and got this message. Installing with sdkmanager fixed the issue.

* Fix thrown errors

runResult had a toString() but we moved to ProcessResult when switching to ProcessManager to this ended up throwing "Instance of ProcessResult".

* Fix package import

* Fix more package imports

* Move mock implementation into Mock class

There seemed to be issues using Lists in args with Mockito that I couldn't figure out (docs say to use typed() but I couldn't make this compile with these lists still)..

* Rename method that's ambigious now we have create

* Handle where there's no avd path

* Add another toList() :(

* Remove comment that was rewritten

* Fix forbidden import

* Make optional arg more obviously optional

* Reformat doc

* Note that we create a pixel device in help text

* Make this a named arg

Emaultor keeps running on a seuccessful launch, so this automatically returns after 3 seconds if the process hasn't quit (we have to wait for some period to get stderr in the case of a failure).

It's too fast and leaves weird output on the screen

Very basic support for "flutter emulators" which just lists the available Android AVDs.
