GoldenFileComparator class
Compares rasterized image bytes against a golden image file.
Instances of this comparator will be used as the backend for matchesGoldenFile.
Instances of this comparator will be invoked by the test framework in the TestWidgetsFlutterBinding.runAsync zone and are thus not subject to the fake async constraints that are normally imposed on widget tests (i.e. the need or the ability to call WidgetTester.pump to advance the microtask queue).
