The returned IDXGIAdapter is owned by caller, which is not obvious from the original signature.
Usual pattern in COM is to use out parameters with smart pointers:

ComPtr<IDXGIAdapter> ptr;
FlutterDesktopEngineGetGraphicsAdapter(engine, ptr.GetAddressOf());

With the old signature it's easy to leak the IDXGIAdapter

ComPtr<IDXGIAdapter> ptr;
// This retains the adapter instead of taking ownership
ptr = FlutterDesktopEngineGetGraphicsAdapter(engine);

Pre-launch Checklist

If you need help, consider asking for advice on the #hackers-new channel on Discord.

If this change needs to override an active code freeze, provide a comment explaining why. The code freeze workflow can be overridden by code reviewers. See pinned issues for any active code freezes with guidance.

Note: The Flutter team is currently trialing the use of Gemini Code Assist for GitHub. Comments from the gemini-code-assist bot should not be taken as authoritative feedback from the Flutter team. If you find its comments useful you can update your code accordingly, but if you are unsure or disagree with the feedback, please feel free to wait for a Flutter team member's review for guidance on which automated comments should be addressed.

FlutterDesktopEngineGetGraphicsAdapter is a new API and it would be good to get this in beta before it lands in stable.

Code Review

This pull request refactors the Windows graphics adapter retrieval API to use output parameters and boolean return values across the public C API and C++ wrapper. Review feedback recommends updating the view-specific adapter retrieval function to match this new pattern for consistency and adding null pointer validation for the output parameter in the engine implementation.
