Not compatible with freezed 2.4.2

[rxseb]

Describe the bug Mocktail is not compatible with latest freezed version (2.4.2).

To Reproduce

1. flutter create sample_app
2. Install freezed
3. flutter pub add --dev mocktail
4. See error

   
   The current Dart SDK version is 3.0.2.

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, test >=1.16.0-nullsafety.19 <1.20.0 requires test_api 0.2.19 or analyzer >=1.0.0 <3.0.0. And because test >=1.20.0 <1.21.2 depends on test_api 0.4.9 and test >=1.21.0 <1.21.6 depends on analyzer >=2.0.0 <5.0.0, test >=1.16.0-nullsafety.19 <1.21.6 requires test_api 0.2.19 or 0.4.9 or analyzer >=1.0.0 <5.0.0. And because test >=1.21.6 <1.24.4 depends on analyzer >=2.0.0 <6.0.0 and test >=1.24.4 depends on test_api 0.6.1, test >=1.16.0-nullsafety.19 requires test_api 0.2.19 or 0.4.9 or 0.6.1 or analyzer >=1.0.0 <6.0.0. And because freezed >=2.4.2 depends on analyzer ^6.0.0 and matcher >=0.12.15 <0.12.16 depends on test_api ^0.5.0, one of freezed >=2.4.2 or test >=1.16.0-nullsafety.19 or matcher >=0.12.15 <0.12.16 must be false. And because every version of flutter_test from sdk depends on matcher 0.12.15 and mocktail >=0.1.3 depends on test ^1.16.0, one of freezed >=2.4.2 or flutter_test from sdk or mocktail >=0.1.3 must be false. And because mocktail <0.1.3 requires SDK version >=2.12.0-0 <2.17.0 and sample_app depends on flutter_test from sdk, freezed >=2.4.2 is incompatible with mocktail. So, because sample_app depends on both freezed ^2.4.2 and mocktail any, version solving failed.

Yep, I think it is because the test package, mocktail is currently using a version of the test package 2 years old.

The test version constraint that mocktail has supports the latest version of package:test so that shouldn’t be an issue.

[rxseb]

I think @omensight is right. According to the error message the conflict comes from incompatible resolution for analyzer version, which needs to be >=6.0.0 for freezed 2.4.2, but <6.0.0 for test ^1.16.

test package increased its analyzer version constraint since 1.24.4. So I guess increasing test version constraint to ^1.24.4 should make mocktail compatible with packages requiring analyzer >=6.0.0.

[felangel]

This is due to an incompatibility between package:test (from mocktail), package:analyzer (from freezed), and flutter_test (from the flutter sdk). I took a closer look and I think mocktail can safely avoid depending on package:test with minimal impact to end users which should resolve this sort of issue moving forward (as this isn't the first time this has happened).

[felangel]

This should be resolved in mocktail v1.0.1 apologies for the inconvenience! 👍
