Firebase UI Android v10.0.0-beta01 Release

We're excited to announce Firebase UI Android v10.0.0-beta01. This major update upgrades this library to natively support Jetpack Compose.

What's New in Beta

This development phase focused on 3 key areas of the Auth module:

• Compose Upgrade: Removing legacy XML-based components in favor of modern Kotlin-based Composable components.
• API Redesign: A complete redesign to better support developers and improve maintenance.
• Feature Development: Build and improve upon a suite of features to provide a complete set of authentication flows, including MFA, custom providers and multi-app support.

Note: There are no major changes to the other Firebase UI Android modules (database, firestore and storage).

Improved Core API

The new API comes packed with a host of new supporting features and utilities for managing authentication in your applications. New features include:

• FirebaseAuthScreen: A single entry point that manages the entire auth flow based on your configuration i.e AuthUIConfiguration.

• AuthUIConfiguration: A type-safe configuration object that defines providers, UI theming, MFA, anonymous upgrade, and validation rules for the authentication flow.

• Custom auth injection: For adding custom authentication via create(app, auth).

Native Compose UI & Theming

• Fully Themed: With AuthUITheme, buttons and inputs automatically adopt your app’s Material branding. You can override typography, shapes, and colors, or inject your own ProviderStyle for distinct button looks.

• Slot APIs: The new EmailAuthScreen and PhoneAuthScreen expose slot APIs, giving you access to state (EmailAuthContentState) while letting you render your own UI.

State Management

• State Management: Access multiple supporting functions for managing authentication state is your application. Included in this release are isSignedIn(), getCurrentUser(), and authStateFlow to expose authentication state reactively.

• Reactive Streams: Built on Kotlin Flow for improved integration with Compose and modern Android architecture.

• Lifecycle Management: Controller returned by createAuthFlow(configuration) with start(), cancel(), and dispose() methods.

• Flow Control: start() drives authentication flow per configuration.

• Safe Cancellation: cancel() transitions to Cancelled state gracefully.

• Resource Management: dispose() releases coroutines and listeners to prevent memory leaks

Sample app

The repository's sample application has been upgraded to use the new updates. Updated features include:

• Upgraded application: A "Quickstart" example using FirebaseAuthScreen to demonstrate how to implement a full authentication flow with just a few lines of code.

• Advanced Customization (Slot APIs): A deep dive into using the new Slot APIs (EmailAuthScreen, PhoneAuthScreen), showing how to inject your own custom UI layouts while retaining the library's state management and validation logic.

• Theming & Styling: Examples of using AuthUITheme.fromMaterialTheme() to inherit your app’s branding, and using ProviderStyle to create custom buttons.

• Feature Walkthroughs: End-to-end demonstrations of complex flows, including federated providers, Custom providers, Multi-Factor Authentication (SMS & TOTP) enrollment and Deep Linking.
