Cannot install package `mocktail v0.3.0` with `build_runner 2.3.2` - version solving fails

[dorontal]

Describe the bug

it's not possible to use mocktail with build_runner - both current versions - seem to clash and version solving reports an error.

The current mocktail package v0.3.0 is not building when added to a new project.

When you run flutter pub get with mocktail having been just added, you get the following error:

--

[mocktail_test] flutter pub get
Running "flutter pub get" in mocktail_test...                    1,216ms
exit code 0

--

[mocktail_test] flutter pub get
Running "flutter pub get" in mocktail_test...                   
Because no versions of test match >1.21.4 <1.21.5 and test >=1.16.0-nullsafety.19 <1.16.6 depends on test_api 0.2.19, test >=1.16.0-nullsafety.19 <1.16.6-∞ or >1.21.4 <1.21.5-∞ requires test_api 0.2.19.
And because test >=1.16.6 <1.17.10 depends on analyzer ^1.0.0, test >=1.16.0-nullsafety.19 <1.17.10-∞ or >1.21.4 <1.21.5-∞ 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-∞ or >1.21.4 <1.21.5-∞ requires test_api 0.2.19 or 0.4.9 or analyzer >=1.0.0 <3.0.0.
And because test >=1.21.2 <1.21.3 depends on test_api 0.4.10 and test >=1.21.3 <1.21.4 depends on test_api 0.4.11, test >=1.16.0-nullsafety.19 <1.21.4-∞ or >1.21.4 <1.21.5-∞ requires test_api 0.2.19 or 0.4.9 or 0.4.10 or 0.4.11 or analyzer >=1.0.0 <3.0.0.
And because test >=1.21.5 <1.21.6 depends on test_api 0.4.13 and test >=1.21.6 <1.21.7 depends on test_api 0.4.14, test >=1.16.0-nullsafety.19 <1.21.4-∞ or >1.21.4 <1.21.7-∞ requires test_api 0.2.19 or 0.4.9 or 0.4.10 or 0.4.11 or 0.4.13 or 0.4.14 or analyzer >=1.0.0 <3.0.0.
And because test >=1.21.7 <1.22.0 depends on test_api 0.4.15 and test >=1.22.0 depends on test_api 0.4.16, test >=1.16.0-nullsafety.19 <1.21.4-∞ or >1.21.4 requires test_api 0.2.19 or 0.4.9 or 0.4.10 or 0.4.11 or 0.4.13 or 0.4.14 or 0.4.15 or 0.4.16 or analyzer >=1.0.0 <3.0.0.
And because test 1.21.4 depends on test_core 0.4.16 which depends on frontend_server_client ^2.1.0, test >=1.16.0-nullsafety.19 requires test_api 0.2.19 or 0.4.9 or 0.4.10 or 0.4.11 or 0.4.13 or 0.4.14 or 0.4.15 or 0.4.16 or analyzer >=1.0.0 <3.0.0 or frontend_server_client ^2.1.0.
And because build_runner >=2.2.1 depends on analyzer >=4.4.0 <6.0.0 and every version of flutter_test from sdk depends on test_api 0.4.12, if flutter_test from sdk and test >=1.16.0-nullsafety.19 and build_runner >=2.2.1 then frontend_server_client ^2.1.0.
And because build_runner >=2.3.1 depends on frontend_server_client ^3.0.0 and mocktail 0.3.0 depends on test ^1.16.0, one of flutter_test from sdk or build_runner >=2.3.1 or mocktail 0.3.0 must be false.
And because no versions of mocktail match >0.3.0 <0.4.0 and mocktail_test depends on mocktail ^0.3.0, flutter_test from sdk is incompatible with build_runner >=2.3.1.
So, because mocktail_test depends on both build_runner ^2.3.2 and flutter_test from sdk, version solving failed.
pub get failed (1; So, because mocktail_test depends on both build_runner ^2.3.2 and flutter_test from sdk, version solving failed.)
exit code 1

To Reproduce Steps to reproduce the behavior:

1. In VSCode, start a new flutter project
2. Add mocktail to your pubspect.yaml's dev dependencies
3. Add 'build_runner to your pubspect.yaml's dev dependencies`
4. Run flutter pub get

When you run flutter pub get you will see the version solving error .

Expected behavior I expected flutter pub get to not fail.

Logs Run flutter analyze and attach any output of that command below.

Hi @dorontal 👋 Thanks for opening an issue!

I am not able to reproduce. The pubspec.yaml I have looks like:

Does the above pubspec.yaml not work for you as well?

[dorontal]

Hi @felangel, please accept my apologies for reporting less than I should have.

Originally I thought the conflict was with package build_runner - it is.

Try adding build_runner as a package - that's when I had the version solving failure.

[dorontal]

The pubspec.yaml for that test code (created by VSCode on new project, with manually added mocktail and build_runner) that failed version solving is (relevant excerpt):

dependencies:
  cupertino_icons: ^1.0.2
  flutter:
    sdk: flutter

dev_dependencies:
  build_runner: ^2.3.2
  flutter_lints: ^2.0.0
  flutter_test:
    sdk: flutter
  mocktail: ^0.3.0

[dorontal]

Here's a workaround: If you change the version of build_runner from ^2.3.2 to 2.2.1 version solving works and flutter pub get doesn't crash. The following dependency combo works:

dependencies:
  cupertino_icons: ^1.0.2
  flutter:
    sdk: flutter

dev_dependencies:
  build_runner: 2.2.1
  flutter_lints: ^2.0.0
  flutter_test:
    sdk: flutter
  mocktail: ^0.3.0

[Sureya]

I am also facing the same issue with the following dependecies. When I comment out mocktail, everything seems to work fine.

dev_dependencies:
  flutter_test:
    sdk: flutter

  flutter_lints: ^2.0.1
  mocktail: ^0.3.0
  build_runner: ^2.3.2
  freezed_annotation: ^2.2.0
  freezed: ^2.2.1
  hive_generator: ^2.0.0

Error message

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 test_api 0.2.19 or 0.4.9 or analyzer >=1.0.0 <3.0.0.
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 test_api 0.2.19 or 0.4.9 or 0.4.14 or analyzer >=1.0.0 <5.0.0.
And because test >=1.21.7 <1.22.0 depends on test_api 0.4.15 and test >=1.22.0 depends on test_api 0.4.16, 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 analyzer >=1.0.0 <5.0.0.
Because no versions of hive_generator match >2.0.0 <3.0.0 and hive_generator 2.0.0 depends on analyzer ^5.0.0, hive_generator ^2.0.0 requires analyzer ^5.0.0.
Thus, if hive_generator ^2.0.0 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.
And because mocktail >=0.1.3 depends on test ^1.16.0, if hive_generator ^2.0.0 and mocktail >=0.1.3 then test_api 0.2.19 or 0.4.9 or 0.4.14 or 0.4.15 or 0.4.16.
And because $PROJECT depends on flutter_test from sdk which depends on test_api 0.4.12, hive_generator ^2.0.0 is incompatible with mocktail >=0.1.3.
So, because $PROJECT depends on both mocktail ^0.3.0 and hive_generator ^2.0.0, version solving failed.
pub get failed (1; So, because $PROJECT depends on both mocktail ^0.3.0 and hive_generator ^2.0.0, version solving failed.)

[se1ya]

Same problem for me. Fixed it with test_api dependency override like: dependency_overrides: test_api: 0.4.16

Here the stackoverflow answer

[felangel]

Unfortunately, it doesn't appear to be related to mocktail. The following pubspec.yaml has the same issue:

publish_to: none

  sdk: ">=2.18.0 <3.0.0"

  flutter:
    sdk: flutter

dev_dependencies:
  build_runner: ^2.3.2
  flutter_test:
    sdk: flutter
  test: any
