AssertionError: /Volumes/Work/s/w/ir/cache/builder/src/out/ios_debug_sim_arm64_extension_safe/libios_test_flutter.dylib is older than /Volumes/Work/s/w/ir/cache/builder/src/out/ios_debug_sim_arm64_extension_safe/libFlutter.dylib. Please run the following commands: 
gn --ios --unoptimized --runtime-mode=debug --no-lto --simulator
ninja -C /Volumes/Work/s/w/ir/cache/builder/src/out/ios_debug_sim_arm64_extension_safe ios_test_flutter
```

It failed we in run_test.py we check if the ios_test is built after the framework, which is not true anymore after moving the test inside the build target.
