Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a new getting started guide for FirebaseUI Auth v10 on Android. The guide focuses on the new Compose-based authentication library, detailing its integration, configuration, and customization capabilities. It aims to provide developers with a clear path to implement modern authentication flows using Jetpack Compose, while also offering guidance for migrating from previous versions.

Highlights

New Compose-based Authentication Flow: The recommended sign-in flow for FirebaseUI Auth v10 now leverages Jetpack Compose screens, moving away from Intent builders and ActivityResultLauncher callbacks for a more modern Android development experience.
Enhanced Features and UI: FirebaseUI Auth v10 introduces Credential Manager integration for faster sign-in, Material 3 UI that can inherit app themes, and built-in flows for multi-factor authentication, account management, linking, and anonymous user upgrades.
Comprehensive Provider Configuration: The guide details how to configure various authentication providers, including email/password, phone, Google, Facebook, Apple, GitHub, Microsoft, Yahoo, Twitter, anonymous auth, and custom OAuth, with specific setup instructions for Google Sign-In and Facebook Login.
Customization and Theming: Version 10.x offers significantly more customization options, allowing developers to set themes directly in authUIConfiguration, inherit app themes, or build fully custom AuthUITheme instances.
Migration Guidance: The documentation provides clear mapping for migrating from older FirebaseUI Auth flows (9.x), explaining how AuthUI.getInstance().createSignInIntentBuilder() and AuthUI.IdpConfig.*Builder() translate to the new Compose-based APIs.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Code Review

The pull request introduces a new GETTING_STARTED.md documentation file for FirebaseUI Auth for Android, detailing its features, setup, provider configuration, sign-in/out flows, customization, and migration guidance. A review comment suggests improving the dependency declarations in this new guide by replacing <latest-version> placeholders with specific, known-working versions to prevent potential build issues and enhance user experience.

What does this mean? Is there a way for us to point developers to docs for them to check whether or not their app is setup for Jetpack Compose?

Let's assume developers reading this guide are already using Jetpack Compose and remove this line.

What if we had a list pointing to the other docs instead of detailing the steps for each of the providers?
