Why Use Firebase with Flutter?

Firebase is a Backend-as-a-Service (BaaS) platform provided by Google. It offers a comprehensive suite of tools like authentication, cloud storage, real-time database, analytics, and more. Integrating Firebase into a Flutter app offers several advantages:

• Cross-platform support (iOS, Android, Web)
• Built-in scalability
• Rapid development cycle
• Secure and reliable infrastructure
• Managed services with minimal configuration

When you combine the flexibility of Flutter with the power of Firebase, the result is a modern, efficient, and production-ready mobile application stack.
