Flutter Firebase Kit

Flutter Firebase Kit is a complete, production-ready Flutter boilerplate built for developers who want to skip the setup and start shipping. Every feature you need for a real app is already wired up — Firebase Authentication (email, Google, Apple), Firestore with offline support, Cloud Functions, push notifications via FCM, and a clean project structure that scales. The architecture follows Clean Architecture principles with Riverpod for state management, making your codebase easy to test, maintain, and hand off to a team. No more copy-pasting from tutorials or fighting with boilerplate. Whether you're building a SaaS, marketplace, or a client project — this kit gives you a solid foundation so you can focus on what makes your app unique.
