nemu_tracking_flutter 1.2.0

Nemu Smart Links attribution SDK for Flutter - UTM tracking, deep linking, and install attribution.

Changelog

1.2.0

• Add support for Nemu-format UTM parameters (nemu_source, nemu_medium, nemu_adset, nemu_campaign, nemu_content, nemu_term).
• When any nemu_* parameter is present, the Nemu set takes full precedence and traditional utm_* parameters are ignored (no merging). utm_medium resolves from nemu_adset first, then nemu_medium.
• URLs with only traditional utm_* parameters keep the existing behavior.
• Nemu keys are excluded from custom_params.

1.1.1

• Fix type 'Null' is not a subtype of type 'String' crash when deserializing session/attribution responses that omit optional fields. Tolerant JSON parsing across TrackingSession, CreateTrackingSessionResponse, TrackingSessionHistory, TrackingInfo, Attribution, and SessionDetail.
• Make server-optional metadata fields nullable (ip, origin, createdAt, updatedAt, dashboardId, accountId, nested tracking/lastHistory) so missing values no longer abort requests and trigger retries.
• Example app now targets the production base URL by default (removed hardcoded local baseUrl).

1.1.0

• Track organic cold starts with origin: 'direct' when the app opens without a URL.
• Allow custom baseUrl without requiring debug mode.
• Handle Universal Links without a smartLinkId in the path by falling back to URI scheme attribution flow.
• Default productData to utmSource: 'direct' when no UTMs are present.
• Enrich utmContent with nemu_{trackingSessionId} suffix in getLastSessionHistory().
• Breaking: Upgrade app_links dependency to v7 (requires Flutter >= 3.38.1 and Dart >= 3.10.0).

1.0.0

• Initial release on pub.dev.
• Smart Links attribution, UTM tracking, deep linking (Universal Links and custom URL scheme), and deferred install attribution.
• Session management aligned with the Nemu trackings API (/trackings/.../sessions, histories, prefetch/cache).
• HTTP client with retries and structured error logging.
