koolbase_flutter 3.2.0

Flutter SDK for Koolbase — feature flags, remote config, version enforcement, authentication, storage, database, realtime, OTA updates, and code push for mobile apps.

3.2.0 - 2026-05-24

• Added KoolbaseConflictException, thrown by insert, update, and upsert when a write violates a collection's unique constraint (HTTP 409). Catch it to handle duplicates.

3.1.1 - 2026-05-23

• Docs: document upsert and deleteWhere in the README (no code changes).

3.1.0 - 2026-05-23

• Added Koolbase.db.upsert(collection:, match:, data:) — insert-or-update by a match filter; returns KoolbaseUpsertResult { record, created }. Online-only.
• Added Koolbase.db.deleteWhere(collection:, filters:) — bulk delete by filter; returns the number of records deleted. Online-only.

3.0.0 — 2026-05-22

Breaking

• Flat record shape. KoolbaseRecord no longer wraps your fields under a data envelope. Your fields are now top-level, with system metadata in a reserved $-prefixed namespace: $id, $createdAt, $updatedAt, $collection, and $createdBy (when set).
• Removed KoolbaseRecord.projectId and KoolbaseRecord.collectionId — internal identifiers are no longer exposed on records.
• Requires a Koolbase server on the flat record contract (shipped alongside this release). Older servers return the legacy envelope and will not parse.

Added

• record['field'] — direct field access, shorthand for record.data['field'].
• record.collection — the record's collection name.

Changed

• Populated/related records (via populate()) and realtime payloads now use the same flat $-shape as direct reads.
• Offline cache (Drift) bumped to schema v2: stale read caches are cleared on upgrade so they refetch in the new shape; pending offline writes are preserved.

Migration

• Remove any record.projectId / record.collectionId usage — those fields are gone.
• record.data['field'] still works; record['field'] is the new shorthand.

2.11.0 — 2026-05-19

Added

• Sign in with Google — production-ready end-user OAuth via Koolbase.auth.signInWithGoogle(idToken: ..., nonce: ...). Routes to the server endpoint at /v1/sdk/auth/oauth/google with RS256-only JWKS verification against Google's certs endpoint, multi-audience support (iOS / Android / web client IDs configured per environment), 15-minute replay defense, and optional nonce check.
• Three new typed exceptions in auth_exceptions.dart: GoogleSignInNotConfiguredException, InvalidGoogleTokenException, GoogleEmailRequiredException. Reuses existing OAuthEmailConflictException and UserDisabledException.

Example with the google_sign_in package

import 'package:google_sign_in/google_sign_in.dart';

final googleUser = await GoogleSignIn().signIn();
final googleAuth = await googleUser?.authentication;

final user = await Koolbase.auth.signInWithGoogle(
  idToken: googleAuth!.idToken!,
);

Auto-link policy

Same as Apple Sign-In (v2.10.0). A new Google identity attaches to an existing user only when BOTH the Google email AND the existing user's email are verified, AND emails match (case-insensitive). Otherwise sign-in either creates a new user (no email collision) or surfaces OAuthEmailConflictException.

Configuration required

Before users can sign in with Google, configure the provider for your environment. Run this against your Koolbase project's project_oauth_configs (dashboard UI for OAuth config lands in a later release):

UPDATE project_oauth_configs
   SET google_client_ids = ARRAY[
         '<your-ios-client-id>.apps.googleusercontent.com',
         '<your-android-client-id>.apps.googleusercontent.com',
         '<your-web-client-id>.apps.googleusercontent.com'
       ],
       enabled = true
 WHERE environment_id = '<your-env-id>'
   AND provider = 'google';

Get the client IDs from Google Cloud Console under Credentials → OAuth 2.0 Client IDs. You'll need one per platform (iOS, Android, web).

Coming next

• React Native SDK v1.11.0 — same surface
• Dashboard UI for OAuth config — replaces the SQL workflow

Documentation

• README rewritten to accurately reflect the v2.10.0 SDK surface. No SDK code changes; this release exists to refresh the README rendered on the pub.dev package page.
• Removed fictional Koolbase.auth.signInWithGoogle reference. Google Sign-In is planned for v2.11.0 — noted explicitly in the OAuth section.
• Replaced the deprecated KoolbaseAppleAuth.signIn() example with the new Koolbase.auth.signInWithApple(identityToken: ..., nonce: ..., fullName: ...) v2.10.0 API using the sign_in_with_apple package.
• Added Koolbase.auth.authStateChanges.listen() example.
• Replaced the Firebase/Supabase comparison table with a Koolbase-only feature inventory.
• Bumped install snippet from ^2.8.0 to ^2.10.0.

2.10.0 — 2026-05-19

✨ New features

Sign in with Apple — production-ready end-user OAuth.

After being deprecated in v2.5.0 through v2.9.x (the old implementation routed to the dashboard OAuth endpoint at /v1/auth/oauth and never created project-scoped end-user sessions), Apple Sign-In is now properly supported via a dedicated server endpoint at /v1/sdk/auth/oauth/apple.

// Get the Apple credential using any native Apple Sign-In library
// (sign_in_with_apple, etc.) — the SDK is library-agnostic.
final credential = await SignInWithApple.getAppleIDCredential(
  scopes: [AppleIDAuthorizationScopes.email, AppleIDAuthorizationScopes.fullName],
);

// Pass the credential to Koolbase.
final user = await koolbase.auth.signInWithApple(
  identityToken: credential.identityToken!,
  nonce: credential.nonce,  // optional but recommended (replay defense)
  fullName: credential.givenName != null
      ? AppleFullName(
          givenName: credential.givenName,
          familyName: credential.familyName,
        )
      : null,
);

Server-side verification runs against the project's configured Bundle ID via Apple's JWKS — RS256-only, audience-bound to your project's iOS app, with replay defense (iat max-age of 15min) and optional nonce check.

Auto-link policy: A new Apple identity attaches to an existing user only when BOTH the provider email AND the existing user's email are verified, AND emails match (case-insensitive). Otherwise sign-in either creates a new user (no email collision) or surfaces OAuthEmailConflictException (collision but auto-link rule blocked — user can sign in with existing method and link from settings).

Four new typed exceptions for granular error handling:

Exception	When
AppleSignInNotConfiguredException	Apple not enabled for this environment in dashboard OAuth config
InvalidAppleTokenException	Token signature, audience, expiry, replay, or nonce check failed
AppleEmailRequiredException	Apple didn't return email AND no existing identity. Recovery: revoke this app's Apple ID access in iOS Settings → Apple ID → Sign-In & Security → Apps Using Apple ID
OAuthEmailConflictException	Email matches existing user but auto-link rule blocked

Configuration required

Before users can sign in with Apple, configure the provider for your environment via direct DB insert against project_oauth_configs (the dashboard UI is on its way — landing in v2.10.1 or v2.11.0):

INSERT INTO project_oauth_configs (environment_id, provider, bundle_id, enabled)
VALUES ('<your-environment-id>', 'apple', 'com.yourapp.bundle', true);

You'll need your iOS app's Bundle ID — it's the audience claim in identity tokens from native Sign in with Apple, and must match exactly.

Still deprecated — KoolbaseAppleAuth.signIn and oauthLogin

These remain deprecated and continue to throw UnimplementedError. The v2.10.0 surface is koolbase.auth.signInWithApple(...) on the auth client — same place as all other auth methods. The class-level KoolbaseAppleAuth.signIn(callback) API from v1.5.0 was a wrong-shape design (callback-based, locked consumers to a specific native library) and won't be revived.

Coming next

• Dashboard UI for OAuth config (v2.10.1) — minimal Bundle-ID input, enable/disable toggle, validation. Removes the SQL-direct workflow.
• Google Sign-In (v2.11.0) — same endpoint pattern at /v1/sdk/auth/oauth/google
• GitHub OAuth (v2.12.0) — code-exchange flow

2.9.1

Polish release: configurable HTTP timeout, injectable HTTP client, and a logout() that lets you know whether the server-side call succeeded. Also fixes a wiring oversight from v2.9.0: the device metadata headers introduced in that release were not actually being attached to requests — the SDK had the code but no construction site. v2.9.1 wires it through properly.

Fixed

• Device metadata headers (from v2.9.0) are now actually attached to authentication requests. v2.9.0 introduced the DeviceMetadata class and the supporting koolbaseSdkVersion constant, and AuthApi was updated to accept a DeviceMetadata instance — but the Koolbase.initialize() flow was not updated to construct one and pass it in. As a result, no x-koolbase-* headers or structured User-Agent were sent on the wire from v2.9.0. v2.9.1 restores the intended behavior. Upgrade from v2.9.0 to get the metadata features described in the v2.9.0 release notes.

Added (2.9.1)

• KoolbaseConfig.authTimeout (Duration, default 10s): timeout applied to every authentication HTTP request. Tune up for high-latency networks; tune down for fast-fail UX on first-byte latency.
• KoolbaseConfig.httpClient (http.Client?, default null): inject your own HTTP client for logging interception, retry middleware, proxy configuration, or sharing connection pools. The SDK will NOT close a caller-supplied client; the caller owns its lifecycle. Currently scoped to auth requests; other SDK modules (storage, database, realtime, etc.) will adopt this in a future release.
• AuthApi.dispose() closes the underlying HTTP client iff the SDK owns it. Called automatically by KoolbaseAuthClient.dispose() for clean shutdown.

Changed

• KoolbaseAuthClient.logout() now returns Future<bool> instead of Future<void>. The local session is always cleared regardless of whether the server-side logout succeeded (intentional best-effort behavior to avoid leaving stale tokens client-side after a network error). The return value indicates whether the server-side call succeeded — true if it did (or if there was no access token to invalidate), false if the server call failed. Source-compatible for callers ignoring the return value.
• KoolbaseAuthClient.dispose() now also cascades to AuthApi.dispose() so the HTTP client gets closed on shutdown.

Usage

// Default: 10s auth timeout, SDK-owned http.Client
await Koolbase.initialize(KoolbaseConfig(
  publicKey: 'pk_live_...',
  baseUrl: 'https://api.koolbase.com',
));

// Custom timeout for slow networks
await Koolbase.initialize(KoolbaseConfig(
  publicKey: 'pk_live_...',
  baseUrl: 'https://api.koolbase.com',
  authTimeout: const Duration(seconds: 30),
));

// Inject your own HTTP client (logging, retries, proxy, etc.)
final myClient = MyLoggingClient();
await Koolbase.initialize(KoolbaseConfig(
  publicKey: 'pk_live_...',
  baseUrl: 'https://api.koolbase.com',
  httpClient: myClient,
));

// Check whether server logout succeeded
final ok = await Koolbase.auth.logout();
if (!ok) {
  // Local session was cleared; server may not be fully aware
}

2.9.0

A comprehensive overhaul of the authentication module. This release closes seven independent gaps identified by a focused security and reliability audit, adds proper device-attributed session tracking, fixes a refresh-token race that could invalidate concurrent in-flight requests, and honestly deprecates OAuth methods that were never fully wired up on the server side.

Highlights

• Pluggable storage: a new KoolbaseAuthStorage abstract interface lets you plug in custom storage backends (compliant encryption layers, web targets, in-memory test mocks). The default SecureAuthStorage now persists the full session — access token, refresh token, expiry, and user — not just the refresh token.
• Offline-aware session restoration: restoreSession() returns a RestoreResult enum (noSession / restored / expired / offline) so your app can render the correct UI immediately. App launches no longer require a network round-trip to show authenticated state.
• Single-flight refresh: concurrent API calls that find an expired token now share one underlying refresh call, fixing a race where parallel refreshes could invalidate each other's tokens.
• Expanded typed exceptions: AccountLockedException, RateLimitException, UnlockTokenInvalidException, TokenRevokedException — covering brute-force lockouts (HTTP 429), general rate limits, the unlock-email flow, and centrally revoked sessions.
• Device metadata on every auth request: a structured User-Agent plus x-koolbase-* headers (SDK version, platform, app version, stable per-install device label) so the server's sessions infrastructure can attribute activity for the sessions UI, future security alerts, and analytics.

Added

• KoolbaseAuthStorage abstract interface — implement your own to plug in custom auth storage backends.
• SecureAuthStorage default implementation backed by flutter_secure_storage with explicit iOS Keychain accessibility (first_unlock_this_device) and Android EncryptedSharedPreferences.
• PersistedSession value class for fully-typed session persistence.
• RestoreResult enum returned by KoolbaseAuthClient.restoreSession().
• KoolbaseAuthClient.unlock(String token) — consume an unlock token from a brute-force unlock email.
• DeviceMetadata class built automatically at Koolbase.initialize(); persists a stable per-install device label.
• koolbaseSdkVersion constant exported for consumers who need to assert SDK version at runtime.
• New typed exceptions:
  • AccountLockedException — brute-force lockout (HTTP 429 + lockout marker). Includes a forward-compatible nullable lockedUntil field.
  • RateLimitException — general HTTP 429 without the lockout marker.
  • UnlockTokenInvalidException — invalid or expired unlock email token (one-shot).
  • TokenRevokedException — session has been revoked centrally (distinct from SessionExpiredException).

Changed

• KoolbaseAuthClient.restoreSession() signature changed from Future<void> to Future<RestoreResult>. Source-compatible for callers ignoring the return value; callers wanting offline-aware UI should branch on the enum.
• AuthApi constructor is no longer const — it now accepts optional DeviceMetadata. Source-compatible for code that doesn't use the const keyword (the default in most apps).
• KoolbaseAuthClient.refreshSession() and the internal _ensureValidToken() go through a single-flight refresh path; concurrent callers share one underlying refresh.
• Every authenticated request now carries User-Agent, x-koolbase-sdk, x-koolbase-sdk-version, x-koolbase-platform, x-koolbase-platform-version, x-koolbase-app-version, and x-koolbase-device-label headers.

Fixed

• Refresh-token race: parallel API calls hitting an expired token no longer trigger competing refresh calls. Server-side refresh-token rotation no longer invalidates peer in-flight tokens.
• Offline launch: restoreSession() previously cleared all auth state on any error including network failures, silently logging users out. It now distinguishes auth rejection from network errors and keeps optimistic state in the offline case.
• 401-on-refresh: refresh failures returning HTTP 401 previously surfaced as InvalidCredentialsException ("wrong password"). They now correctly throw SessionExpiredException.
• Profile updates not persisting: updateProfile(), getCurrentUser(), and linkPhone() updated in-memory state but didn't re-persist the user. Changes were lost on app restart. Now persisted via a new internal helper.
• linkPhone listener not firing: profile updates after phone linking now correctly emit on authStateChanges.
• forgotPassword silently swallowed errors: now properly checks the response status and surfaces errors as typed exceptions.

Deprecated

• OAuth methods: KoolbaseAuthClient.oauthLogin(), AuthApi.oauthLogin(), and KoolbaseAppleAuth.signIn(). The previous implementations targeted /v1/auth/oauth — the dashboard's developer OAuth handler — which never created project-scoped sessions for end-users. All three methods now throw UnimplementedError. Proper end-user OAuth endpoints (/v1/sdk/auth/oauth/apple, /google, /github) are tracked for v2.10.x. Use KoolbaseAuthClient.login() with email/password until then.
• AuthStorage class: replaced by SecureAuthStorage. The old class remains as a @Deprecated subclass for source compatibility and will be removed in v3.0.0.

Migration

If you construct AuthStorage directly:

// Before
final client = KoolbaseAuthClient(api: api, storage: AuthStorage());

// After (recommended — uses the default)
final client = KoolbaseAuthClient(api: api);

// Or explicit
final client = KoolbaseAuthClient(api: api, storage: SecureAuthStorage());

If you handle restoreSession():

// Before
await Koolbase.auth.restoreSession();
if (Koolbase.auth.isAuthenticated) {
  // Show app
} else {
  // Show login
}

// After (recommended — branch on outcome)
final result = await Koolbase.auth.restoreSession();
switch (result) {
  case RestoreResult.noSession:
    // Show login
  case RestoreResult.restored:
    // Show app
  case RestoreResult.expired:
    // Show login with "session expired" message
  case RestoreResult.offline:
    // Show app optimistically; retry refresh when network returns
}

If you call oauthLogin() or KoolbaseAppleAuth.signIn():

These now throw UnimplementedError. End-user OAuth is blocked on a server-side endpoint that ships in v2.10.x. Use email/password authentication via KoolbaseAuthClient.login() for now.

If you catch generic KoolbaseAuthException for lockout or rate-limit cases:

Consider catching the more specific types now:

try {
  await Koolbase.auth.login(email: email, password: password);
} on AccountLockedException {
  // Show "account temporarily locked" UI; offer "unlock via email" path
} on RateLimitException {
  // Show "too many attempts, please wait" UI
} on InvalidCredentialsException {
  // Show "wrong email or password"
}

Internal

• KoolbaseAuthClient no longer imports package:flutter/material.dart (was only needed for debugPrint in OAuth error paths, which are now deprecated stubs).
• New lib/src/auth/device_metadata.dart module.

2.8.0

• Functions: Authenticated invocations now forward the signed-in user's session automatically.
  • When a user is signed in via Koolbase.auth, calls to Koolbase.functions.invoke() include their access token in the request.
  • Functions receive caller identity via ctx.auth — a map with user_id (string or null) and is_authenticated (bool).
  • Unauthenticated invokes continue to work; Functions decide whether they require auth and respond with AUTH_REQUIRED if needed.
  • Token refresh is handled transparently — the next invoke after a refresh uses the fresh token without any client-side wiring.
• Backwards compatible: no breaking changes. Existing code paths continue to work.

2.7.0

Phone + OTP authentication

Sign users in with their phone number — for emerging markets and apps where email isn't the primary identifier.

New methods on Koolbase.auth:

• sendOtp({required String phoneNumber}) — sends a 6-digit OTP to an E.164 phone number, returns the expiry timestamp.
• verifyOtp({required String phoneNumber, required String code}) — verifies the code and signs the user in (creates the account if new). Returns PhoneVerifyResult with an isNewUser flag for routing first-time users to onboarding.
• linkPhone({required String phoneNumber, required String code}) — links a phone number to an already-authenticated user.

New types: OtpSendResult, PhoneVerifyResult.

KoolbaseUser now exposes phoneNumber and phoneVerified fields.

New exceptions: InvalidPhoneNumberException, OtpExpiredException, OtpInvalidException, OtpMaxAttemptsException, OtpRateLimitException, PhoneAlreadyLinkedException, SmsConfigMissingException.

Phone numbers must be in E.164 format (e.g. [phone]). Configure your SMS provider (Twilio, Africa's Talking, or Hubtel) in the Koolbase dashboard before using.

final result = Koolbase.executeFlow(
  flowId: 'on_checkout_tap',
  context: { 'plan': user.plan },
);
if (result.hasEvent) {
  Navigator.pushNamed(context, result.eventName!);
}

2.1.0

Layer 2 — Server-Driven UI via rfw

• Added KoolbaseDynamicScreen — drop-in widget that renders server-defined UI from the active bundle
• Added KoolbaseCodePushScope — InheritedWidget that wires the code push client into the widget tree

Usage

// Wrap your app with KoolbaseCodePushScope
KoolbaseCodePushScope(
  client: Koolbase.codePush,
  child: MyApp(),
)

// Drop KoolbaseDynamicScreen anywhere
KoolbaseDynamicScreen(
  screenId: 'onboarding',
