lander_flutter 0.2.0

Deep linking without the fuss: receive, resolve and create Lander links, and report opens and conversions from Flutter apps.

0.2.0

Deferred deep linking.

• Deferred links from POST /v1/sdk/init arrive through getInitialLink and onDeepLink as before, now with isDeferred, confidence (deterministic, probabilistic or unattributed) and the new LanderLink.method (install_referrer, probabilistic_match, landing_page, authenticated_handoff, universal_link, app_link). Still delivered exactly once, and a link that opened the app wins over a deferred one.
• Android: installs from a Lander link land on that link's screen. The redirector now puts a single use lander_token in the Play Store referrer, which the SDK already sends on first launch (deterministic, install_referrer).
• Lander.claimHandoff(userId): after sign in, returns the link your backend bound to that user with POST /v1/handoffs (deterministic, authenticated_handoff), or null. Returned only, never emitted on onDeepLink. Retries reuse one Idempotency-Key, so a lost response does not lose the link.
• Custom scheme URLs that carry a short link in lander_link (the iOS "Continue in app" page's open button) are resolved like the link itself; uri stays the scheme URL, and if resolving fails the scheme URL's path still routes.
• sdkVersion reported as 0.2.0.

0.1.0

First release: the installed app path.

• Lander.initialize: random install ID (UUID v4, stored outside backups), POST /v1/sdk/init on every launch with isFirstLaunch, Play Install Referrer on Android first launch. Never throws on network errors; a failed first launch report is retried on the next launch with the same idempotency key, and an install_id_conflict gets a fresh install ID.
• Lander.onDeepLink and Lander.getInitialLink: Universal Links, App Links and custom scheme URLs on cold and warm start, resolved through POST /v1/sdk/resolve. Links are buffered until the app listens, the launch link is delivered exactly once, and unknown links (404) or network failures still deliver the raw URL.
• Lander.createLink: short links from inside the app via POST /v1/sdk/links.
• Lander.trackEvent: persistent offline queue, batches of up to 100, exponential backoff with jitter and Retry-After, deduplication by client generated event ID, flush on app background, held until the install is registered. Optional linkId for attribution.
• Request timeouts (10 s) and an Idempotency-Key on every write, reused across retries.
• Android (Kotlin): launch intent and onNewIntent delivery, Recents replay ignored, Play Install Referrer.
• iOS (Swift): app delegate and UIScene based apps, NSUserActivity Universal Links and URL opens, privacy manifest.
• Example app: Acme Shop with go_router.
