Expo Google Auth Module

The `expo-google-auth` package, currently at version 0.3.0, offers a dedicated solution for integrating Google authentication into React Native Expo applications. It achieves this by leveraging Google's modern Identity API and Credential Manager, presenting an updated approach to handling user sign-ins compared to traditional methods. While it provides two primary authentication methods, the module explicitly recommends "Method 1" as the latest approach endorsed by Google. A crucial aspect of this library is its current platform limitation: it exclusively supports Android environments. Developers targeting iOS are directed to use `expo-auth-session` for their authentication needs. Launched publicly in November 2025, the package has seen a consistent, albeit minor, release cadence, signaling ongoing development. To function correctly, users must perform essential Google Credentials setup for both Android and web clients, which includes obtaining and configuring a Google Web Client ID. This package aims to simplify Google sign-in workflows specifically for Android within the Expo ecosystem.
