[SEVERE] Failed to precompile build script .dart_tool/build/entrypoint/build.dart. This is likely caused by a misconfigured builder definition.

I have tried overriding the analyzer dependency to 1.5.0 but it causes conflicts with other dependencies in the project.

Running flutter doctor shows the same errors in the terminal.

This is related to upgrading to mockito v5.3.0, dart pub upgrade might solve it. if not, revert mockito version to 5.2.0 and it should work.

mockito: 5.2.0 without the ^

both does not work for me. Also overriding code_builder: ^4.2.0 as recommended here does not work for me. github.com/dart-lang/mockito/issues/552#issuecomment-1208973838
Make sure you write 5.2.0 without ^
And try doing flutter clean if still not fixed
writing mockito: 5.2.0 without the ^did the trick, thanks! :-) Maybe you could include that explicitly into your answer.
With mockito 5.3.2 the problem was solved for me.

The issue is caused by analyzer package, that it's used as a dependency for mockito.

Seems like the new version 4.4.0 deprecated a few APIs.

What I did to fix it for now (until maintainers fix it on the package) is to include analyzer as a dependency on my pubspec.yaml with latest stable version 4.3.1 and it works now.

dev_dependencies:
  analyzer: 4.3.1

Hope this helps
