After upgrading Flutter, the integration tests on the iOS emulator crash

[tformatix]

If you are looking for help, please confirm the following...

• I confirm I have searched the Docs, Codemagic Sample Projects, and GitHub Discussions.
• I confirm the software versions on my local computer match the ones in CI environment (e.g. Xcode version, Gradle version). See here
• I confirm I am able to do a fresh clone of the repository and build the project on my local computer.

Which mobile framework are you using?

Flutter (Dart)

Steps to reproduce

1. Upgrade from Flutter 3.19.1 to Flutter 3.22.3 (flutter upgrade)
2. Upgrade packages with flutter pub upgrade
3. Change from Theme.of(context).colorScheme.background to Theme.of(context).colorScheme.surface as background is deprecated
4. Fixing other integration tests that did not work with the new version (too little scrolling and missing/wrong mocks)

Expected results

All integration tests should be run as before.

Actual results

Apparently the tests crash at a certain point. The tests crash at different points (somehow different, sometimes they are the same). Rarely do all tests run successfully.

This is the error message:

hey @tformatix try localy to remove pubspec.lock and podfile.lock files then run flutter pub get and pod install. New .lock files will be generated, then try your tests again. If everything is ok push the changes and re-run the build

Hey @dtrdic, thank you for your fast replay. Seems to be working now. Sorry to have wasted your time - this is an issue we could have considered as well.

no problem, i'm glad it worked:)
