Scale weighings are now written to Apple Health and Health Connect as weight samples. Before this, the scale weight stayed inside the app.
What changes
New lib/health/health_weight_export.dart. It applies the same household filter as the trend (10 to 300 kg, chained 10% band, re-seed after 3 near rejects). It keeps a persisted set of exported timestamps per device (health_weight_exported:<id>, newest 2000), so a re-run does not duplicate samples.
Failures are bounded: kMaxWeightAttempts (6), cleared by reset and by force retry. A failed weighing is skipped and the rest continue. A hung store is guarded by a timeout and _storeHung, as for the deletes.
Permission is requested once per install, on both platforms. The write is always attempted afterwards, because Health Connect's hasPermissions(WRITE) is unreliable.
health_export.dart: WEIGHT joins _types but deliberately not healthDeleteTypes or _rewriteTypes, so a delete or rewrite pass can never touch the user's weight history. A test enforces this. exportScaleWeighings runs at the end of exportAll.
Imported profile weights are not echoed back to Health.
Maintainer decisions needed
New Android permission WRITE_WEIGHT in AndroidManifest.xml.
It reuses the existing health_sync toggle; there is no separate opt-in for weight.
The iOS usage-description wording in Info.plist.
Tests: test/health_weight_export_test.dart, test/health_profile_import_test.dart; the weight, health and observation tests pass (50). 4 commits, fine to squash.
Known limits
A guest or child as the very first weighing is still exported, and a Health write cannot be recalled.
Only the newest 2000 exported timestamps are tracked per device, so very old late arrivals beyond that are skipped.
Weight export runs inside _workoutLock, so a hung permission prompt could briefly delay workout export.
The exported set is rewritten after every weighing and the weight table is re-read on each drain.
Deleted or edited weighings are not removed from Health.
The ±500 ms delete-own window can remove a neighbouring sample.
Export only runs at the tail of exportAll, so a new weighing alone does not trigger it.
Independent of the trend PR (#666); the files are disjoint.
Summary by Sourcery
Export paired-scale weighings to Apple Health and Health Connect without affecting imported profile weights or existing health rewrite flows.
New Features:
Export eligible scale weighings to Apple Health and Health Connect as weight samples with per-device idempotency tracking.
Bug Fixes:
Prevent imported profile weights and health maintenance passes from being echoed into or removing user weight history.
Bound failed weight writes and continue exporting later weighings when individual writes fail or the health store becomes unresponsive.
Enhancements:
Reuse the health sync setting, request weight-write access at most once per installation, and support retries after permission grants or forced retries.
Keep weight-export state local to the device and exclude it from backups and restores.
Apply household plausibility filtering and safe duplicate handling for resets and potentially landed writes.
Deployment:
Declare Health Connect weight-write permission and update the iOS Health usage description for scale weighings.
Tests:
Add coverage for filtering, idempotency, retries, permission behavior, timeout handling, reset safety, backup policy, and exclusion from day-based health deletion and rewrite passes.
Summary by CodeRabbit
New Features
Scale weight readings can now be exported to Health alongside other health data, using kilograms.
Health write access is checked and requested when needed for weight exports.
Weight export progress and retry information is included in backups.
Bug Fixes
Invalid, out-of-range, and already-exported readings are skipped.
Failed exports can be retried, with limits on repeated attempts; timed-out writes are handled to help avoid duplicates.
Nearby readings from other scales are protected from deletion during export.
Weight export errors do not affect the reported result of the broader health-data export.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
Health export now requests WEIGHT authorization and exports eligible scale weighings after bulk export unless the store is marked hung. The exporter tracks per-device state, retries, and permission status. Health weight export preferences receive backup handling.
Changes: Scale weighing Health export
Layer / File(s)
Summary
Weighing selection and export state lib/health/health_weight_export.dart, lib/data/backup_extras.dart
Filters candidate weighings, selects pending weighings under retry and run limits, and persists per-device export state. Backup preferences exclude per-install permission keys and assign stored types to the new per-item keys.
Permission and sample write behavior lib/health/health_weight_export.dart
Checks WEIGHT write permission and requests it at most once. Supports guarded deletion before eligible retries and tracks successful exports, failed attempts, and possibly landed writes.

Merge Risk: Moderate · up to ca5ec
Weight samples can be duplicated in Health after a restore on the same phone, after very long histories, or after an interrupted reset. These cases are uncommon and the effect is duplicate samples rather than data loss. Resolve the deduplication gaps before merge, or accept them explicitly.

**Guest weight reaches health store**
When a guest or child is the first person weighed after pairing or a reset, `exportableWeighings` accepts the first plausible weighing without establishing who used the scale, and `exportScaleWeighings` sends it to the linked health store under the account owner. A guest’s or child’s weight is therefore disclosed as the owner’s health data.
Require user confirmation or another reliable attribution signal before exporting an unassigned first weighing.

**Opt-outs do not stop an active drain**
When the user disables Health Sync or a scale after the export has started but before that scale's pending weighings are written, `exportScaleWeighings` continues using the earlier sync and device-enabled checks without rechecking either setting before writing. If the user turns off Health Sync or disables the scale during a long export, pending weighings are still sent to Health after the opt-out.
Recheck the current Health Sync and device-enabled settings before each weighing is written, and stop the drain when either is disabled.

**Reset can erase existing weighings**
When a reset re-sends a weighing already present in Health and deletion succeeds but the replacement write fails repeatedly, `writeWeighings` deletes the existing sample before attempting its replacement. If that write fails, the weighing is counted as a failed attempt; after the retry cap, the previously exported sample is gone from Health.
Avoid deleting the existing sample until the replacement is safely written, or otherwise preserve and restore the prior sample when the write fails.

</code_context>
<issue_to_address>
**Timed-out writes can duplicate samples**
When a Health write exceeds `_deleteTimeout`, remains active, and completes after a later drain's delete-and-write retry, `Future.timeout` does not cancel the underlying Health write. A later drain can delete the sample before that timed-out write finishes, then write a replacement; when the original write completes afterward, both samples remain in Health.
Prevent a new attempt until the timed-out native operation is known to have settled, or reconcile the matching interval after the original operation completes.

<issue_to_address>
**One scale blocks later scale exports**
When loading one enabled scale's weight observations throws, the outer `try` catches the loader error and exits `exportScaleWeighings` instead of continuing the device loop, so weighings from every later enabled scale remain unexported until a later run succeeds.
Catch and log failures per device so one scale's database error does not stop exports for the remaining scales.

</code_context>
<issue_to_address>
**Older failed weighings disappear**
When more than 2,000 newer weighings are exported while an older weighing is still failing, `exportScaleWeighings` uses the minimum retained exported timestamp as `floor` to filter `pending`, including weighings that have not reached the retry limit. Once newer exports move `floor` past an older failed weighing, every later run skips it, leaving it missing from Health.
Apply the retained-export floor only to successful exports that need deduplication, not to pending failed weighings.

</code_context>
<issue_to_address>
**Retry limit is not verified**
When the retry limit is reduced below `kMaxWeightAttempts` while still allowing one retry, `failure continues to later weighings; bounded retries` never counts failed writes, so an implementation that permanently suppresses a weighing after only two failures still passes this loop and final zero-write assertion. The separate retry test requires only one retry, so the configured six-attempt limit is not protected.
Count attempts for the failing timestamp and assert it is tried exactly `kMaxWeightAttempts` times before being suppressed.
</issue_to_address>

</code_context>
<issue_to_address>
**Hung-store stop is not verified**
When the store becomes hung on the first fake write, `a hung store ends the run without burning attempts` only checks that the run returns zero; its fake write always returns false and records no call count or attempt state. An implementation that ignores `stopped` and processes the second weighing still passes, as does one that counts the hung failure before the later successful run.
Record the initial run's write calls and persisted failure counts, then assert it stops after the first call without incrementing that weighing's attempts.
</issue_to_address>

Prune persisted attempt entries for weighings that are no longer loaded.
Each failed weighing adds an entry under healthWeightAttemptsKey. Entries are removed only on success, reset, or forced retry. Each save writes the full map, including entries for weighings that are no longer in raw. Those entries cannot match any pending weighing.
Persist only entries whose weighing is still in raw. Keep entries for every loaded weighing, including those at kMaxWeightAttempts. Removing those would restart their retry budget. This limits the map to the weighings the device still has stored. It does not set a fixed size limit.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
The WEIGHT write timeout stops awaiting the Future but does not cancel the underlying store write; a late completion can race a later delete-and-retry and create a duplicate.
Two samples for the same weighing can remain in Health despite the timestamp-set deduplication.
This can occur when: A platform write times out, then eventually commits after the next export has deleted the window and begun its retry write.

- Around line 1143-1149: Update exportAll so exportScaleWeighings does not hold
_workoutLock while processing an unbounded queue: move the weight pass outside
the lock or impose a per-run cap, while preserving existing reset, retry, stop,
permission, and deletion behavior.
- Around line 1142-1144: Restructure the flow around exportPriorityOrBulk so
failures in its day-result reads or bulk export do not skip
exportScaleWeighings. Keep the _storeHung guard and preserve the existing error
and return behavior while ensuring weighings are attempted independently.
- Around line 580-583: Update request() so that after requestAuthorization
returns normally, it records kHealthWeightPermAskedPref because the
authorization request includes HealthDataType.WEIGHT. Leave the marker unset if
requestAuthorization throws, preserving the scale path’s existing retry
behavior.
- Around line 684-688: Update weightWritePermitted so a thrown or timed-out
permission check cannot prevent the one-time permission request from running.
Define how an unknown check result is handled after the request: preserve the
rule that the write is attempted once the ask has run without treating an
unknown result as a confirmed grant that can consume attempts when permission is
absent; establish the existing permission-request outcome or safeguard that
supports both behaviors before changing the write path.
Review comments at @lib/health/health_weight_export.dart:
- Around line 158-162: Update the delete-before-write logic in the weighing loop
so it only removes the app-written WEIGHT sample belonging to the current scale
and weighing, rather than any sample within 500 ms; preserve samples from other
scales and ensure a failed delete still prevents writing over the uncleared
instant.
- Around line 256-262: Update the weight export flow that builds pending from
exportableWeighings to clear the relevant attempts counts when WEIGHT access
changes, so weighings previously capped can be retried after access is granted;
preserve the attempt cap during ordinary exports.
- Around line 229-233: Update exportScaleWeighings so each device’s database
read, enabled check, and export work is isolated in its own try-catch inside the
device loop, allowing later scales to proceed after a failure. Keep the outer
try-catch limited to loading SharedPreferences and deviceRows.

…neighbour, a failed reset rewrite stays pending
a write that timed out may have landed. the instant is now stored per scale and cleared before the retry, only when no other weighing sits inside the match window. when a reset deleted our sample and the replacement failed, the weighing was still marked exported and stayed missing from health until the next reset; it is pending again now.

Restore on the same phone can duplicate weight samples in Health.
The backup exclusion assumes the restored install writes to an empty Health store. On the same phone, the earlier samples may still exist. The exporter then sees those weighings as unexported and writes them again. The normal write path does not check for existing samples, so the duplicates are not prevented. The same applies to an interrupted write recorded only in health_weight_maybe_landed:.
Choose one of these changes:
Keep the exported state for a restore onto the same Health store, and exclude it only for a new phone.
Check the Health store for an existing sample at the same instant before writing.

…s, late older weighings are sent
the exporter's marks now restore with the rest of the settings, since the health store usually survives a restore and re-sending everything would stack duplicates. only the permission flags stay per install. a switched-off scale's instants count in the collision check. exported weighings that age out of the bounded set are remembered separately, so an older weighing that shows up late is still sent instead of being mistaken for one that aged out.

Keep deduplication information after the trimmed-history limit.
After 12,001 eligible weighings have been exported, the two persisted sets retain only the newest 12,000 timestamps. The oldest weighing remains in d.raw, but neither set contains its timestamp.
The next ordinary export selects that weighing again. Saving immediately evicts its old timestamp from exported, and this bound drops it from trimmed again. Each later export can therefore write another duplicate. With enough omitted timestamps, these repeated writes also consume the 200-weighing budget.
Keep durable deduplication information for entries removed by this bound. Preserve the distinction between previously exported entries and unseen backfills.

…ved too
the trimmed set was only written when the bound evicted something, so after a reset deleted an aged-out sample and the rewrite failed, the old mark came back on restart and the weighing looked exported. it is saved whenever it changes now. the cap's comment says what is forgotten past it.

Persist the exported mark before the trimmed mark is removed.
When a reset replaces a trimmed weighing, save() persists the trimmed removal before the exported addition. If the app stops or a preference write fails between them, the instant is in neither persisted set. The next ordinary export then writes that weighing again. The new sample can duplicate the replacement already in Health.
Write additions to trimmed before the exported write, so an evicted instant is never in neither set. Write removals from trimmed after the exported write. Alternatively, persist the related state atomically.

Scale weighings are now written to Apple Health and Health Connect as weight samples. Before this, the scale weight stayed inside the app.
What changes
lib/health/health_weight_export.dart. It applies the same household filter as the trend (10 to 300 kg, chained 10% band, re-seed after 3 near rejects). It keeps a persisted set of exported timestamps per device (health_weight_exported:<id>, newest 2000), so a re-run does not duplicate samples.kMaxWeightAttempts(6), cleared by reset and by force retry. A failed weighing is skipped and the rest continue. A hung store is guarded by a timeout and_storeHung, as for the deletes.hasPermissions(WRITE)is unreliable.health_export.dart:WEIGHTjoins_typesbut deliberately nothealthDeleteTypesor_rewriteTypes, so a delete or rewrite pass can never touch the user's weight history. A test enforces this.exportScaleWeighingsruns at the end ofexportAll.Maintainer decisions needed
WRITE_WEIGHTinAndroidManifest.xml.health_synctoggle; there is no separate opt-in for weight.Info.plist.Tests:

_workoutLock, so a hung permission prompt could briefly delay workout export.exportAll, so a new weighing alone does not trigger it.Independent of the trend PR (#666); the files are disjoint.
