Todd Volkert e19db89a0e Add basic support for golden image file testing (#17094) ... * Add a `matchesGoldenFile()` async matcher that will match a finder's widget's rasterized image against a golden file. * Add support for pluggable image comparison backends * Add a default backend that does simplistic PNG byte comparison on locally stored golden files. * Add support for `flutter test --update-goldens`, which will treat the rasterized image bytes produced during the test as the new golden bytes and update the golden file accordingly Still TODO: * Add support for the `flutter_test_config.dart` test config hook * Utilize `flutter_test_config.dart` in `packages/flutter/test` to install a backend that retrieves golden files from a dedicated `flutter/goldens` repo https://github.com/flutter/flutter/issues/16859		2018-04-30 10:35:56 -07:00
