AttributionContext class

Last-click attribution + session tracking for in-app events.

LinkForty attributes in-app activity (events and screen views) to the deep link that drove it, using a last-click + window model:

• Every deep-link open (deferred install OR direct re-engagement) pins an active context to THAT link. The newest open wins (supersede).
• Every event is stamped with the active context so the backend can credit the link. The conversion window and session grouping are applied server-side at query time — the SDK only reports the active link, when it opened, and the current session.
• A sessionId identifies one app-open journey: generated on cold start and rotated on each new deep-link open.

The active context is persisted so a reopen without a new click still attributes to the last link. The session is in-memory: a cold start is a new session.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

sessionId → String

The current session id (one app-open journey).

no setter

Methods

clear() → Future<void>

Clears the persisted context and starts a fresh session (used by clearData).

getStamp() → AttributionStamp

The attribution fields to merge into every event payload.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

recordDeepLinkOpen({String? linkId, String? clickId}) → Future<void>

Records a deep-link open. The newest open supersedes the previous one (last-click) and starts a new session. A no-op when no linkId is known (organic/unresolved open) — there is nothing to attribute to.

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
