Failed to precompile build script .dart_tool/build/entrypoint/build.dart – Flutter

I am facing a problem while updating the ferry package from 0.10.4 to 0.13.0. When executing dart run build_runner build --delete-conflicting-outputs, it always throws the next error:

`[WARNING] Invalidated precompiled build script due to core package update
[WARNING] Error: Cannot run with sound null safety, because the following dependencies
don’t support null safety:

  • package:quiver

For solutions, see https://dart.dev/go/unsound-null-safety
[INFO] Precompiling build script… completed, took 3.3s
[SEVERE] Failed to precompile build script .dart_tool/build/entrypoint/build.dart.
This is likely caused by a misconfigured builder definition.`

These are my ferry packages:

 #ferry configurations:
  ferry: ^0.13.0
  gql_http_link: ^0.4.5

dev_dependencies:
   flutter_test:
    sdk: flutter
  ferry_generator: ^0.7.0
  flutter_lints: ^2.0.1
  build_runner: ^2.3.3

I have also tried adding gql 0.14.0 to dependency_overrides but it throws the same error. Any clue about a possible solution?

    The problem was 'mockito' library. After upgrading it version I was able to upgrade 'ferry' and 'ferry_generator' libraries.

dependency_overrides:
