Generating build_script fails in Flutter channel Dev (1.10.7)

[GregorySech]

Steps to Reproduce

1. Create a new application with the default template flutter create example
2. Add functional_widget and functional_widget_annotation to pubspec.yaml

   
   dependencies:
   flutter:
   sdk: flutter
   functional_widget_annotation: ^0.5.1

builders: functional_widget: ^0.7.1

3. Run the application. It will fail with: `Error generating build_script snapshot: Could not find a file named "pubspec.yaml" in "/Users/gregorysech/.pub-cache/hosted/pub.dartlang.org/functional_widget-0.7.1".
`

## Logs

<!--
      Run your application with `flutter run --verbose` and attach all the
      log output below between the lines with the backticks. If there is an
      exception, please see if the error message includes enough information
      to explain how to solve the issue.

Consider reporting this to Flutter repo. The package cannot do much about it, it's an exception from Flutter's tooling

Thank you, I just wanted to make sure. I'll post it after work, should I keep this open?
