Previously, we could not include any Objective-C types in test_metal_context.h, since that file was transitively included in pure C++ translation units. All users have been refactored into backend-specific files, and all Metal-related files are Objective-C++ files. We now use Metal types directly in the header, without the workarounds. Issue: https://github.com/flutter/flutter/issues/158998 Issue: https://github.com/flutter/flutter/issues/137801 [C++, Objective-C, Java style guides]: https://github.com/flutter/engine/blob/main/CONTRIBUTING.md#style
