Failed to recognize a platform plugin after Flutter 3.27

[AlexV525]

This crashes users without notice or awareness, please consider this a severe regression.

Workaround

Adding the plugin to app/pubspec.yaml can solve the issue.

Steps to reproduce

See https://github.com/AlexV525/flutter_issue_160143 for a reproducible example

1. flutter create app
2. flutter create --template=package foundation
3. Under the foundation, run flutter pub add fvp
4. Under the app, run `flutter pub add 'foundation:{"path":"../foundation"}'
5. Run flutter pub get for app
6. No com.mediadevkit.fvp was generated in the android/app/src/main/java/io/flutter/plugins/GeneratedPluginRegistrant.java.
7. Import package:fvp/fvp.dart and add registerWith() before runApp.
8. Run the app on Android and see exceptions occurred.

Expected results

The plugin registrant should be generated no matter the plugin was declared at once it's been referenced.

Actual results

The plugin was unrecognized through the above setup.

Thanks for the report @AlexV525
I tried to follow the steps provided but at step 4, I am hitting below error:

Using a naked argument for directory is deprecated and will stop working in a
  future Flutter release.

  Use --directory instead.
Expected to find project root in foundation:{"path":"../foundation"}.

Which is same as #144898

Is there a way for you to provide us a repo that we can directly clone to verify this further ?

Thanks for it. I somehow missed it from OP.
Using the repo, I was able to replicate on latest sdk versions (stable and master).
Based on the report and error received with it, I will keep the issue open for team's tracking.
I wasn't able to verify this on previous stable though due to version conflict, as the message said to upgrade to latest stable.

stable : 3.27.0
master : 3.28.0-1.0.pre.87
