Matan Lurey 4cd0e33013 Implement golden-file matching for integration_test on Android and iOS devices (#160484) ... Work towards https://github.com/flutter/flutter/issues/143299. Work towards https://github.com/flutter/flutter/issues/160043. --- This PR implements, end-to-end, support for `matchesGoldenFile` when (a) running with `package:integration_test` (b) on a device, such as an Android emulator, Android device, iOS simulator, or iOS device, where the _runner_ of a test file does not have process and local-file system access. There are multiple parts to this PR; I could make it smaller than 1K lines, but the bulk of that is tests, and it would mean landing PRs that are incomplete and unused, which does not seem useful - so instead here is a quick overview of the PR's contents - questions/feedback welcome, and I am willing to break code out or land incremental refactors if requested. 1. Augmented `flutter_platform.dart` (used for iOS and Android), similar to [`flutter_web_platform.dart`](1398dc7eec/packages/flutter_tools/lib/src/test/flutter_web_platform.dart (L117-L128)), now creates and uses [`test_golden_comparator.dart`](https://github.com/flutter/flutter/blob/master/packages/flutter_tools/lib/src/test/test_golden_comparator.dart) to proxy calls (coming from the VM service protocol) for golden-file updates and comparisons to a `flutter_tester` process. A full explanation of how (or why) it works this way is too hard to include here, but see https://github.com/flutter/flutter/pull/160215 for more details. 1. Added `VmServiceProxyGoldenFileComparator`, which is a currently unused (outside of a single e2e test) comparator that forwards calls to `compare` and `update` to the VM service protocol (of which, the other side of this is implemented above, in `flutter_platform.dart`. The idea is that this comparator would be used automatically when running in an integration test on a device that requires it (similar to how web works today), but that is **not** wired up yet and requires additional work in `flutter_tools`. 1. Added two unit tests (of both the client and server), and a full e2e-test using it to run `matchesGoldenFile`.		2024-12-28 19:48:20 +00:00
