authowl_client library

AuthOwl headless client SDK for Flutter apps.

This entrypoint exposes the client and session layer without importing widgets. Most applications should import authowl.dart, which re-exports this API together with the managed Flutter UI.

final auth = AuthOwlClient(
  publishableKey: 'pk_live_…',
  apiUrl: 'https://api.authowl.dev',
  storage: mySecureStorage,   // flutter_secure_storage in an app
);

await auth.getSession();
auth.session.changes.listen((state) => setState(() {}));

final result = await auth.signInWithEmail(email: e, password: p);
if (!result.isSuccess) showError(result.error!.message);

Social sign-in takes an ID token from the provider's native SDK. Redirect OAuth is unsupported on purpose - it completes inside a system browser whose cookie jar this client cannot read, so the session would land somewhere the app can never see it.

The paths this calls are pinned by conformance/client-surface.json, derived from @authowl/core and drift-checked in CI.

Constants

authChallengeHeader → const String
Header carrying a single-use bot-challenge token.
maxAkedlyShieldDifficulty → const int
Same ceiling enforced by the AuthOwl server and web SDK.
maxResponseBytes → const int
Ceiling on a response body. A hostile or misconfigured endpoint should not be able to exhaust memory on a phone.
requestTimeout → const Duration

Functions

createAuthOwlIdempotencyKey() → String
Create a cryptographically random RFC 4122 version 4 identifier.
decodePublishableKey(String key) → PublishableKey
Validate a publishable key and extract its project id.
projectAuthPayload(String path, Object? payload) → Object?
Strip the engine's long-lived session token out of the exact response families that carry one.
readSetCookie(List<String> setCookieValues, String name) → String?
Parse one named cookie out of the response's Set-Cookie headers.

Typedefs

AuthOwlChallengeTokenProvider = Future<String?> Function(AuthOwlChallengeAction action)
Mints a fresh, single-use bot-challenge token for a built-in auth form.

Exceptions / Errors

AuthOwlException
Error types shared across the AuthOwl Flutter SDK. Base class for every error this SDK throws.
PublishableKeyException
A publishable key could not be decoded.
