As far as I can tell, the tests for dev/integration_tests/hook_user_defines were never added to a CI build and currently don't run.

They also fail when running them locally with flutter test:

Unhandled exception:
Invalid argument(s): User-define `magic_value` must be an integer, found: null.
#0      main.<anonymous closure> (file:///Users/goderbauer/dev/flutter/dev/integration_tests/hook_user_defines/hook/build.dart:13:7)
#1      build (package:hooks/src/api/build_and_link.dart:158:18)
#2      main (file:///Users/goderbauer/dev/flutter/dev/integration_tests/hook_user_defines/hook/build.dart:10:9)
#3      _delayEntrypointInvocation.<anonymous closure> (dart:isolate-patch/isolate_patch.dart:312:33)
#4      _RawReceivePort._handleMessage (dart:isolate-patch/isolate_patch.dart:193:12)

This failure is probably due to resolution: workspace in the package's pubspec.yaml. The workspace pubspec does not define a value for the magic_value user define. Only the package-local pubspec does. We probably don't want random test user defines in the root pubspec. Maybe this packages has to be removed from the workspace?

Steps necessary to close this issue:

• Fix the tests of dev/integration_tests/hook_user_defines
• Make these tests run on CI somewhere (maybe as parts of the tools integration test shard?) so they don't break again.
