There is an open Pull Request to merge into bases local_auth package.

Addresses issue: #49703

Device credentials

The original plugin only supports biometric authentication. This package add a method that allows for device credentials if biometric authentication is not available.

localAuth.authenticate() behaves the same as the original plugin's localAuth.authenticateWithBiometrics() but also allows device credentials (pin, pattern, passcode) to be use.

Check if device supports

final LocalAuthentication auth = LocalAuthentication();

// API 23 and up with security features enabled for Android
// Any iOS device
bool isSupported = await auth.isDeviceSupported();

Authenticate by any means

final LocalAuthentication auth = LocalAuthentication();

authenticated = await auth.authenticate(
    localizedReason: 'Let OS determine authentication method',
    useErrorDialogs: true,
    stickyAuth: true);

Check biometrics

final LocalAuthentication auth = LocalAuthentication();

bool isBiometricsAvailable = await auth.canCheckBiometrics();

Authenticate with only biometrics

final LocalAuthentication auth = LocalAuthentication();

authenticated = await auth.authenticateWithBiometrics(
    localizedReason: 'Biometrics only',
    useErrorDialogs: true,
    stickyAuth: true);
