Description

The stable plugins table still lists Data Connect as N/A on Windows. firebase_data_connect is published with Windows as a supported platform, and its Firebase dependencies (firebase_core, firebase_auth, and firebase_app_check) all ship Windows implementations. The other Windows plugins in that table (Authentication, Cloud Firestore, Cloud Storage, Core, and Remote Config) are marked (*): development only, with production unsupported.

This changes the Data Connect Windows cell from N/A to (*).
