* Adding segmented control to gallery

* Fix use of Future<void> as a Future<bool>

This should make it more obvious from the error what's gone wrong if we see a repeat of #19096 (previously the error was something like "Bad state: future already completed").

* Rename util -> test_utils

* Rename flutter_test_driver -> test_driver

* Switch testWithContext -> test

* Remove unused import

* Move test project into a class to make it easier to have multiple of these

Each "TestProject" class can contain its files and things like named breakpoint locations.

* Split expression evaluation tests into own file

* Include last response in error messages

* Update expectations based on current bugs

* Fix async-ness in tests

* Fix incorrect expectation in test

* Fix incorrect evaluations

* Remove skips for tests that are now passing on master

* Expect pass on Linux

🤷‍♂️

* Call the code

* Skip expression evaluation tests on Windows

* Skip whole group, not just one test

* Remove duplicated method from merge

* Fix misplaced close of group

* Remove code that was duplicated from test we copied

Not sure how this ended up in here?

* Re-fix typo

Added animation to segmented control widget.

This allows us to collect code coverage for Fuchsia tests.

A significant amonut of code uses defaultTargetPlatform, so it's
currently impossible to run most apps on Windows. This adds a mapping
from Windows as a host to Android as a target, paralleling the
macOS->iOS and Linux->Android mappings.

This allows more use of Windows as a host platform (e.g., for testing,
as in issue #17768).

This will let us re-use that code from fuchsia_tester.dart.
Tested by running the stocks example tests with coverage collection before and after.
.lcov files are identical.

Put the nav bar padding inside the CustomMultiChildLayout for correct centering and allow custom padding (#19129)
