[google_maps_flutter] native-test fails - "bitwise operation between different enumeration types ('enum CGBitmapInfo' and 'enum CGImageAlphaInfo')"

[preethi0228-git]

Steps to reproduce

1. Clone flutter/packages
2. Navigate to google_maps_flutter_ios example
3. Run:
   dart run script/tool/bin/flutter_plugin_tools.dart native-test --ios --packages=google_maps_flutter_ios

• Reproduced on:

  • iOS 26.4 simulator
  • iOS 26.5 simulator

• Works correctly when run via Xcode on the same simulators / real device

Expected results

Build and tests should pass as they do in Xcode.

Actual results

Build is failing with which the tests are not executed.

Note : Issue repro on both Master and Stable channels too

Hi @preethi0228-git
Thanks for providing the logs.

Routing to team-ecosystem to evaluate the plugin's dependencies and compiler flags for compatibility with upcoming Xcode releases.

Essentially a duplicate of #184470, but I wonder why it wasn't excluded from native-test and still failed after flutter/packages#11480. Maybe passing in --packages=google_maps_flutter_ios overrides the exclusion.

Ah, I see, CI knows to pass in --xcode-warnings-exceptions=script/configs/xcode_warnings_exceptions.yaml

https://github.com/flutter/packages/blob/4a2091d89f77d4c202d6c6a9b541a42c954fbfff/.ci/targets/ios_platform_tests.yaml#L29
@preethi0228-git can you update your test scripts to match the exclusions in that ios_platform_tests.yaml files? For example:
drive-examples --ios --exclude=script/configs/exclude_integration_ios.yaml
https://github.com/flutter/packages/blob/4a2091d89f77d4c202d6c6a9b541a42c954fbfff/.ci/targets/ios_platform_tests.yaml#L39
