Overview
Flutter App Lock is a Flutter package that enables developers to implement a lock screen interface when the app launches or pauses. It provides a simple way to secure app access using biometric authentication (like fingerprint or face recognition) or a custom PIN/password. The package supports multiple platforms including Android, iOS, Web, macOS, Windows, and Linux, making it ideal for cross-platform applications requiring user authentication. It integrates seamlessly with Flutter's widget system and allows customization of the lock screen UI and behavior.
Use cases
