Pre-launch Checklist

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

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.

Code Review

This pull request enables Impeller by default on macOS by updating the default return value of enableImpeller to YES in FlutterDartProject.mm. It also updates the hello_world_impeller_macos_sdfs devicelab task to run without the explicit --enable-impeller flag. A formatting issue was identified in the Dart test file where a line exceeds the length limit and needs to be wrapped to comply with the style guide.

'run',
options: <String>['--enable-impeller', '-d', 'macos'],
);
final Process process = await startFlutter('run', options: <String>['-d', 'macos']);

medium

This line exceeds the 80-character limit and will be wrapped by dart format. Please format it to comply with the style guide and avoid CI failures.

Suggested change
final Process process = await startFlutter('run', options: <String>['-d', 'macos']);
final Process process = await startFlutter(
'run',
options: <String>['-d', 'macos'],
);
