Empty daytime metrics: ask for the band through the day, not overnight by kurexw · Pull Request #690 · OpenStrap/edge

kurexw · 2026-11-10T19:00:16Z

Why

On a fresh install, Activity › Steps shows:

Nothing recorded today · Wear the band overnight to start the series

Every metric with no history at all gets that same fix line (metricDetailWearBandFix). It's right for resting heart rate, HRV or sleep, and wrong for metrics a day's wear produces: nobody needs to wear the band overnight to get a step count. Seen on an Android emulator.

What changes

metric_detail.dart: kDaytimeMetricKeys (steps, calories, strain, trimp, active_min, wear, i.e. Steps, Active energy, Strain, Heart effort, Movement minutes, Wear time). For those, the never-recorded card's fix line is the strain screen's existing "Wear the band through the day" (dayStrainWearBandFix).
Every other metric keeps "Wear the band overnight to start the series".
No new l10n key: dayStrainWearBandFix is already translated in all 8 locales.

Only the all.isEmpty case changes; a metric with any history still shows no fix line, as before.

Tests

New test/metric_detail_empty_hint_test.dart: each daytime key shows the daytime hint and not the overnight one; resting_hr, hrv, sleep keep the overnight hint. With the old line restored, the 6 daytime cases fail.
Related suites (metric detail, step goal, advanced charts, Home/Health, metric row trend, component sweep, noun-in-sentence, day steps): 146 passed. flutter analyze: no issues.
Full flutter test --concurrency=1 not re-run for this copy-only change.

🤖 Generated with Claude Code

Summary by Sourcery

Correct empty metric guidance so users are told to wear the band during the day for metrics generated by daytime activity.

Bug Fixes:

Show a daytime wear instruction for never-recorded daytime metrics instead of incorrectly suggesting overnight wear.

Tests:

Add widget coverage confirming daytime metrics use the daytime hint while overnight metrics retain the existing overnight hint.

Summary by CodeRabbit

Bug Fixes
- Empty states now show guidance tailored to the selected metric: daytime metrics prompt users to wear the band during the day, while other metrics retain the overnight instruction.

A metric with no history at all showed "Wear the band overnight to start the series" whatever the metric was. Right for resting heart rate, HRV or sleep; wrong for steps, active energy, strain, heart effort, movement minutes and wear time, which come from the day. Those keys (kDaytimeMetricKeys) now get the strain screen's existing "Wear the band through the day" (dayStrainWearBandFix, already translated in every locale), so no new string. Seen on the Steps screen of a fresh install on an Android emulator.

Reviewer's Guide

UI

Classify daytime-produced metrics and use the existing daytime wear hint for their never-recorded empty state, while preserving the overnight hint for other metrics.

lib/ui2/screens/metric_detail.dart L59-70, L971-975

Tests

Add widget tests verifying that daytime metrics show the daytime hint and selected overnight metrics retain the overnight hint.

Walkthrough

When a metric has no history, the detail screen shows daytime-wear guidance for six defined metrics. Other metrics retain overnight-wear guidance.

Changes: Metric empty-state guidance

Layer / File(s)	Summary
Select empty-state wear guidance `lib/ui2/screens/metric_detail.dart`	`kDaytimeMetricKeys` identifies six daytime metrics. When history is absent, the screen uses daytime-wear guidance for those metrics and overnight-wear guidance for other metrics.

Estimated code review effort: 2 (Simple) | ~8 minutes

Change: Bug fix

Suggested reviewers: abdulsaheel

Merge Risk: Low · up to 324de

New users with no resting HR who follow the daytime-wear instruction for calories, strain or TRIMP may still see an empty series. Adding overnight-wear or manual resting HR guidance would fix this; the issue is bounded and does not block merge.

**Daytime metrics get overnight advice**

When an empty `hrr` or `nap_min` history is opened, `kDaytimeMetricKeys` omits both keys, so `MetricDetail` selects `metricDetailWearBandFix` and tells users to wear the band overnight even though these metrics come from daytime bouts or sleep outside the main night.

Add `hrr` and `nap_min` to `kDaytimeMetricKeys`.

Also at `test/metric_detail_empty_hint_test.dart:27`, `lib/ui2/screens/metric_detail.dart:69`.

**Steps regression goes unnoticed**

When a daytime key such as `steps` is accidentally removed from `kDaytimeMetricKeys`, when `kDaytimeMetricKeys` omits `steps`, the loop at line 27 of `metric_detail_empty_hint_test.dart` stops creating the Steps case, so Steps can show the overnight hint while every remaining assertion passes.

Use an independent explicit list of expected daytime keys in the test, so omissions from the production set fail coverage.

🟡 Medium · Daytime metrics get overnight advice

When an empty hrr or nap_min history is opened, kDaytimeMetricKeys omits both keys, so MetricDetail selects metricDetailWearBandFix and tells users to wear the band overnight even though these metrics come from daytime bouts or sleep outside the main night.

Add hrr and nap_min to kDaytimeMetricKeys.

Include resting-HR guidance for these metrics.

If a new user has no measured, manual or historical resting HR, daytime wear alone cannot produce calories, strain or TRIMP. Add guidance to wear the band overnight or enter resting HR manually, as well as wearing it during the day.
