influto 1.1.1

Track influencer referrals, attribution, and store-direct purchase validation in your Flutter app. Mirrors the InfluTo React Native SDK.

Changelog

1.1.1

Fixed

• setReferralCode() / applyCode() fall back to the user stored by identifyUser() when appUserId isn't passed. Without it the backend rejected free-access codes with MISSING_USER_ID.
• setReferralCode() stores the code (and the manual_entry attribution record) and calls the revenueCatHook only after the backend answers success == true, using the canonical code it returns. A rejected code is no longer stored or tagged. Still fail-soft.
• ReferralCodeInput: the field no longer drops _ (codes allow [A-Z0-9_-]), and onApplied fires only when the code was actually applied (applied == true), not merely valid.

1.1.0

Fixed

• checkAttribution() no longer re-fires /sdk/track-install on every cold start for organic users: the organic (non-attributed) result is now persisted like the attributed one (contract 1.6.0). A failed request still retries on the next launch.

Added

• Persisted per-install UUID (@influto/install_id) sent as device_id, so the backend counts unique devices instead of launches. No permissions, no fingerprinting; resets on reinstall by design.
• Deterministic eventId for once-only monetization events (trial_started, subscription_purchased, subscription_renewed) derived from (event type, user, properties) — cross-launch re-fires collapse server-side.

1.0.0

Initial release of the InfluTo Flutter SDK.

Added

• Full influencer attribution API: initialize, checkAttribution, identifyUser, trackEvent, getActiveCampaigns, validateCode, setReferralCode, applyCode, getReferralCode, getPrefilledCode, clearAttribution — matching the canonical cross-platform contract (wire 1.0.0).
• Store-direct purchase validation via reportPurchase (StoreKit 2 JWS on iOS, Play purchase token on Android), posting to /sdk/purchase. Supports one-time / consumable products via productId/price/currency (NON_RENEWING validation).
• checkAccess — server-authoritative premium-access check powering platform-independent comp (free-access codes that grant entitlement without a purchase); works for both RevenueCat and store-direct apps. Positive results are cached in memory and persisted across cold starts (~5-min TTL).
• Default-on automatic purchase capture for store-direct apps via the companion influto_iap package (InfluToPurchaseObserver) — listens to in_app_purchase and auto-reports purchases; RevenueCat apps stay silent. Declare one-time SKUs via oneTimeProductIds. Configurable through InfluToConfig.autoCapture.
• Optional RevenueCat integration through a host-supplied revenueCatHook callback — no hard dependency on purchases_flutter.
• ReferralCodeInput widget with live debounced validation; showCampaignName and showReferrerName both default to false (influencer name hidden unless explicitly opted in).
• Pure Dart implementation — only http and shared_preferences. Fail-soft behavior on all methods except initialize and reportPurchase.
