Authentication Flow Example

The Flutter example includes a complete authentication implementation:

// From: lib/examples/auth/email_auth_example.dart
Future<void> authenticateWithEmail(String email) async {
  final authState = await para.initiateAuthFlow(
    auth: Auth.email(email)
  );
  
  switch (authState.stage) {
    case AuthStage.verify:
      // New user - show verification UI
      showVerificationScreen();
      break;
    case AuthStage.login:
      // Existing user - login with passkey
      await para.handleLogin(
        authState: authState,
        webAuthenticationSession: webAuthSession,
      );
      break;
  }
