Overview
A Flutter plugin that enables biometric authentication using device sensors like fingerprint readers and Touch ID on Android and iOS. Unlike standard implementations, it supports invisible authentication on Android, meaning no visible dialog appears during the process, providing a seamless user experience. It integrates with native biometric APIs and is ideal for apps requiring background or silent authentication. The plugin is maintained by dvaplus.eu and available via GitHub for customization.
