React Native FirebaseUI Auth

A React Native library that wraps FirebaseUI Authentication, providing a drop-in UI for sign-in methods (email, Google, Facebook, anonymous) on iOS and Android. Version 2.0.0 updates Android dependencies and is compatible with React Native >=0.59.0. Ships TypeScript types. Key differentiators: uses native FirebaseUI SDKs for consistent look-and-feel, supports auth state event listeners, and allows automatic upgrade of anonymous users.
