whisperr 0.2.2

Official Whisperr SDK for Flutter — identify users and track product events to power churn-prevention interventions.

Changelog

0.2.2

• Wire-format conformance with the other Whisperr SDKs (verified against whisperr-spec): identify() now supports preferred_channel, shortcut channels send an explicit opted_in, and empty track() events include a default properties object.

0.2.1

• Each track() event now carries a stable per-event idempotency key ($message_id) in context, reusing the persisted queue op id so it survives restarts and retries. Prevents duplicate events when the durable queue resends after a timeout, matching server-side dedup.

0.2.0

• Breaking: identify() no longer accepts preferredChannel. Whisperr now derives the best channel from engagement; express an explicit user choice with optedIn: false on the channels they don't want.
• Added email, phone, and pushToken shortcut parameters to identify() that expand into opted-in channels — no need to build WhisperrChannel objects for the common case.

0.1.0

• Initial release.
• Whisperr.initialize, identify, track, flush, reset.
• Durable, ordered outbound queue with batched delivery (/v1/events/batch), offline persistence, exponential-backoff retry, and 429/auth/client-error handling.
• App-lifecycle flush on pause/detach.
