BiometricService class

Service for handling biometric authentication.

This service provides a platform-agnostic interface for biometric authentication (Face ID, Touch ID, Fingerprint). It uses the local_auth package when available, or provides a fallback interface.

Example usage:

final service = BiometricService();
if (await service.isAvailable()) {
  final authenticated = await service.authenticate();
  if (authenticated) {
    // Handle successful authentication
  }
}
