Sahha Flutter Plugin

1.4.0 #

Stable release of the 1.4.0 line, consolidating the 1.4.0-beta.1 and 1.4.0-beta.2 changes with the final native 1.4.0 SDKs.

Added #

  • engagement biomarker category in SahhaBiomarkerCategory.
  • Android: skipped unreadable Health Connect records are now reported to Sahha error telemetry, so affected devices are visible without device logs.

Changed #

  • Breaking: SahhaBiomarkerCategory now contains exactly the six documented categories (activity, body, engagement, nutrition, sleep, vitals). Removed characteristic and reproductive, which never returned biomarker data.
  • Breaking: renamed SahhaBiomarkerType.activity_mid_intensity_duration to activity_medium_intensity_duration, matching the server vocabulary — the old name always returned no data.
  • Deprecated getStats and getSamples — use getBiomarkers to read server-processed biomarkers instead.
  • Stat and sample category values now carry the sensor's data-log logType — the same label stamped on uploaded data on both platforms: heart rate types report heart, blood pressure/glucose report blood, oxygen/VO2 max/respiratory rate report oxygen, temperature types report temperature, and energy/daylight types report energy. vitals no longer appears.
  • Rebuilt the example app as a full SDK testing harness.
  • Updated iOS to 1.4.0 — check release notes https://github.com/sahha-ai/sahha-ios/releases
  • Updated Android to 1.4.0 — check release notes https://github.com/sahha-ai/sahha-android-sdk/releases

Fixed #

  • iOS: sensor sets with no HealthKit-backed types (such as device_lock alone, or Android-only sensors) no longer make permission requests throw "Health data types not specified" — requesting permissions now succeeds as a no-op and sensor status reports correctly through the normal lifecycle.
  • iOS: enableSensors no longer risks hanging indefinitely without invoking its callback; profile token refresh and session-expiry handling are hardened against transient network and server errors.
  • Android: enableSensors reports the real sensor status reliably (the native callback now returns a SahhaSensorStatus).
  • Android: eliminated phantom step spikes caused by step-counter regressions and implausible jumps; reboots are detected reliably, and steps recorded during collection outages are recovered.
  • Android: Health Connect reads now step around records the client library cannot parse instead of dropping the surrounding data, and an interrupted read no longer advances the sync marker past unread data.
  • Android: getSamples for steps no longer returns empty or partial results after background sync has run, and queries no longer interfere with upload de-duplication.
  • Android: device-lock events are now stamped with the correct phone form factor.

1.4.0-beta.2 #

Added #

Changed #

Fixed #

  • Android: getSamples for steps no longer returns empty or partial results — step queries previously shared the background upload pipeline's de-duplication state, hiding records already collected by sync (fixed in the native 1.4.0-beta.2 release).

1.4.0-beta.1 #

Added #

  • engagement biomarker category in SahhaBiomarkerCategory.

Changed #

  • Breaking: SahhaBiomarkerCategory now contains exactly the six documented categories (activity, body, engagement, nutrition, sleep, vitals). Removed characteristic and reproductive, which never returned biomarker data.
  • Breaking: renamed SahhaBiomarkerType.activity_mid_intensity_duration to activity_medium_intensity_duration. The old name was outside the documented vocabulary and silently returned no data.
  • Deprecated getStats and getSamples — use getBiomarkers to read server-processed biomarkers instead.
  • Stat and sample category values are now labeled with the sensor's data-log logType: heart rate types report heart, blood pressure/glucose report blood, oxygen/VO2 max/respiratory rate report oxygen, temperature types report temperature, and energy/daylight types report energy. vitals no longer appears.
  • Rebuilt the example app as a full testing harness — biomarker, score, stats and samples query screens with type selectors and date ranges, a checked-list sensor permissions screen, a per-sensor diagnostics screen, and a Material 3 UI.
  • Updated iOS to 1.4.0-beta.1 — check release notes https://github.com/sahha-ai/sahha-ios/releases
  • Updated Android to 1.4.0-beta.1 — check release notes https://github.com/sahha-ai/sahha-android-sdk/releases

Fixed #

  • iOS: enableSensors callback no longer hangs indefinitely; hardened token refresh and session-expiry handling.
  • Android: enableSensors reports sensor status reliably, plus Health Connect read-robustness fixes from the native 1.4.0-beta.1 release.

1.3.9 #

Added #

Changed #

Fixed #
