DartUri: Cannot read packages spec in workspace environment #161469
Description
Steps to reproduce
Short: Create a flutter project inside a workspace and add a web target.
- Create an empty folder
- Add a
pubspec.yamlwith anameandworkspaceattribute - Create a subfolder using
flutter create --platforms=web -e app - Add
resolution: workspaceto itspubspec.yamland the package directory to the root pubspec - Run the project in web
Expected results
Not to print anything (-> not to throw errors)
Actual results
DartUri: Cannot read packages spec: file:///C:/Users/jakob/Documents/GitHub/upsheep/packages/test_app/.dart_tool/package_config.jsonError: PathNotFoundException: Cannot open file, path = 'C:\Users\jakob\Documents\GitHub\upsheep\packages\test_app\.dart_tool\package_config.json' (OS Error: Das System kann die angegebene Datei nicht finden., errno = 2)
(second part is German and means something along the lines of "The system could not find the specified file")
I did some digging and by judging by previous issues, I believe this is an issue directly related to Flutter.
It occurs because pub get deletes said .dart_tool/package_config.json file and "relocates" it to the root project.
Running the project still works, but on every refresh the error is printed. Not very cool

Logs
The instructions say I have to add --verbose, it's quite a long output, so I also attached the output without verbose.

This reveals a lot more DartUri errors than initially thought. Wow
