fix: Using dart_code_metrics and bloc_test creates a dependency problem

[quoc-huynh-cosee]

Description
If I use the latest version of dart_code_metrics and bloc_test, I'm getting a dependency problem.

Steps To Reproduce

1. Create an empty project with these dependencies.

dev_dependencies:
  flutter_test:
    sdk: flutter

  dart_code_metrics: ^5.4.0
  bloc_test: ^9.1.0

2. Run flutter pub get
3. This error will be printed:

Because test >=1.16.0-nullsafety.19 <1.16.6 depends on test_api 0.2.19 and test >=1.16.6 <1.17.10 depends on analyzer ^1.0.0, test >=1.16.0-nullsafety.19 <1.17.10 requires test_api 0.2.19 or analyzer ^1.0.0.
And because test >=1.17.10 <1.20.0 depends on analyzer >=1.0.0 <3.0.0 and test >=1.20.0 <1.21.2 depends on test_api 0.4.9, test >=1.16.0-nullsafety.19 <1.21.2 requires analyzer >=1.0.0 <3.0.0 or test_api 0.2.19 or 0.4.9.
And because test >=1.21.0 <1.21.6 depends on analyzer >=2.0.0 <5.0.0 and test >=1.21.6 <1.21.7 depends on test_api 0.4.14, test >=1.16.0-nullsafety.19 <1.21.7 requires analyzer >=1.0.0 <5.0.0 or test_api 0.2.19 or 0.4.9 or 0.4.14.
And because test >=1.21.7 <1.22.0 depends on test_api 0.4.15 and test >=1.22.0 <1.22.1 depends on test_api 0.4.16, test >=1.16.0-nullsafety.19 <1.22.1 requires analyzer >=1.0.0 <5.0.0 or test_api 0.2.19 or 0.4.9 or 0.4.14 or 0.4.15 or 0.4.16.
And because test >=1.22.1 <1.22.2 depends on test_api 0.4.17 and test >=1.22.2 depends on test_api 0.4.18, test >=1.16.0-nullsafety.19 requires test_api 0.2.19 or 0.4.9 or 0.4.14 or 0.4.15 or 0.4.16 or 0.4.17 or 0.4.18 or analyzer >=1.0.0 <5.0.0.
Because no versions of dart_code_metrics match >5.4.0 <6.0.0 and dart_code_metrics 5.4.0 depends on analyzer >=5.1.0 <5.4.0, dart_code_metrics ^5.4.0 requires analyzer >=5.1.0 <5.4.0.
Thus, if dart_code_metrics ^5.4.0 and test >=1.16.0-nullsafety.19 then test_api 0.2.19 or 0.4.9 or 0.4.14 or 0.4.15 or 0.4.16 or 0.4.17 or 0.4.18.
And because bloc_test >=8.0.0-nullsafety.5 depends on test ^1.16.0, if dart_code_metrics ^5.4.0 and bloc_test >=8.0.0-nullsafety.5 then test_api 0.2.19 or 0.4.9 or 0.4.14 or 0.4.15 or 0.4.16 or 0.4.17 or 0.4.18.
And because untitled depends on flutter_test from sdk which depends on test_api 0.4.12, dart_code_metrics ^5.4.0 is incompatible with bloc_test >=8.0.0-nullsafety.5.
So, because untitled depends on both dart_code_metrics ^5.4.0 and bloc_test ^9.1.0, version solving failed.
pub get failed (1; So, because untitled depends on both dart_code_metrics ^5.4.0 and bloc_test ^9.1.0, version solving failed.)

Expected Behavior
Both packages are compatible with each other.

Hello, this seems like a similar issue to felangel/mocktail#178 (comment), you can find a temporary fix there.
