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.

It looks like this pull request may not have tests. Please make sure to add tests or get an explicit test exemption before merging.

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. If you believe this PR qualifies for a test exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!). The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group.

Code Review

This pull request removes the explicit wide gamut enablement from the macOS integration test configuration and updates the enableWideGamut logic to default to the hardware's support status when no configuration is provided. Feedback was provided to simplify the conditional logic in FlutterDartProject.mm to improve readability and eliminate redundant calls to DoesHardwareSupportWideGamut().

Nevermind, this is ready to commit. I forgot we had the flag checked in. We should be good now.

Code Review

This pull request removes the FLTEnableWideGamut key from the macOS integration test Info.plist and modifies the engine to default to hardware-supported wide gamut when the configuration is missing. Feedback suggests refactoring the enableWideGamut method to simplify the logic and remove redundant hardware checks.

I have a comment about reporting the discrepancy when they don't get the support they explicitly ask for, but I'm not sure it has a good answer.

Meanwhile I think that Gem has a good point about trying (and not being able) to disable the support. And then that adds the idea that maybe we should have a test that shows you can disable it if it is available? Or do we not want them to disable it in that case?

Yea good point, I'll add that.

Or do we want them to enable or disable it at all? Should this be more of a case of:

  • The screen is either wide gamut or not - we should go with that flow?
  • A screen capture has a format now I think? Should the format request wide gamut on a per-capture basis?
  • Images are either loaded wide gamut or not depending on the image format?

Yea, let's just remove the option to opt out. We don't gate every feature behind a flag. We have automated tests that this should work now.

@flar okay, I removed the the option to opt out of wide gamut. This is in alignment with the original issue and absolves us from supporting that workflow and writing a test for it.
