firebase/flutterfire

This system is a comprehensive suite of Flutter plugins for Firebase services, including Firestore, Cloud Functions, Analytics, App Check, App Installations, and Authentication. It provides cross-platform implementations (Android, iOS, macOS, Windows, and Web) that bridge Dart code to native SDKs using the Pigeon framework for type-safe, efficient communication. The codebase has been modernized to support advanced features such as Firestore pipelines, streaming callable functions, and multi-factor authentication, while standardizing project configurations and error handling across all platforms.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 19 July 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 3cefea2c0e — the exact code this score is about.
  • Scored under rubric rubric-2026.08.17. Score the same commit under that rubric and you get the same number.
