Flutter Local Auth vs Android Biometric API

Developers should use Flutter Local Auth when building mobile apps that need local user authentication for features like app locking, sensitive data access, or transaction approvals meets developers should use the android biometric api when building apps that require secure user authentication, such as banking apps, password managers, or any application handling sensitive data. Here's our take.
