A complete Flutter login example with biometric authentication, dark mode, and JSON API integration.
Flutter Login is an open-source example project that demonstrates how to implement a complete authentication system for Flutter apps. It includes login with biometrics (FaceID, TouchID, fingerprint), dark mode, JSON API integration, and a settings page. The project solves the problem of building a secure, polished login flow from scratch by providing a reusable module.
Flutter developers building cross-platform mobile apps who need a ready-to-use authentication system with modern features like biometric login and dark mode.
Developers choose Flutter Login because it offers a production-ready, fully-featured login example with 100% shared code between Android and iOS, reducing development time and ensuring best practices for authentication in Flutter.

Implements FaceID, TouchID, and fingerprint login on both iOS and Android, with sticky auth options to handle app backgrounding, as detailed in the README's platform integration sections.
Includes auto-login, remember me toggle, settings page, and dark mode, providing a full-featured module ready for customization, evidenced by the features list and screenshots.
Uses 100% shared code between Android and iOS, leveraging Flutter's capabilities for efficient development, as stated in the README's description.
Utilizes json_serializable for automatic JSON parsing with REST APIs, simplifying data handling, which is highlighted in the features and getting started sections.
Requires manual updates to Info.plist for iOS and AndroidManifest.xml for Android to enable biometric features, adding complexity and potential for errors, as noted in the README.
As an example project, it lacks regular updates and dedicated support compared to established authentication packages, which could lead to compatibility issues with newer Flutter versions.
Designed to be forked and adapted, making it challenging to integrate into existing projects without significant refactoring, as it's not packaged as a reusable component.
