Description

What problem does this PR solve?

The Android macro widget's protein/carbs/fat bars never showed goal progress — they showed each macro's share of total macro calories, which barely moves as the day fills up, so the bars looked stuck while the kcal header updated.

How did you implement the solution?

  • The three bars are independent LinearProgressIndicators, but progressFor returned macroKcal / macroKcalTotal. Those fractions always sum to one, so they track the day's macro ratio, not progress. With 87 g protein / 184 g carbs / 94 g fat the bars drew 18/38/44% where the dashboard showed 81/77/114%.
  • The widget could not do better, because the snapshot only ever carried consumed grams. useWidgetSync now sends proteinGoal, carbsGoal and fatGoal in the Android macro snapshot. The push dedupe key is the stringified snapshot, so a goal-only change re-pushes rather than being skipped.
  • progressFor now returns consumed / goal, falling back to the previous share-of-total when a goal is absent — snapshots written by an older build, and macros with no goal set, degrade instead of collapsing to empty.
  • The three new optional doubles and the existing remaining parse through one optionalDouble helper, so absent, JSON null and non-finite all read as "not supplied".

The iOS widget is deliberately unchanged. It has the same share-of-total maths, but renders a single segmented MacroRing, where three shares summing to one is the intended reading of a composition chart. Only Android maps those shares onto independent progress bars.

Linked Issue: Closes #2228

How to Test

  1. Check out this branch, then cd SparkyFitnessMobile && pnpm test __tests__/hooks/useWidgetSync.test.ts.
  2. Run npx expo prebuildMacroWidget.kt.tmpl is a template that withCalorieWidget.ts copies into android/ at prebuild, so the change does not reach the app without it.
  3. Launch on an Android emulator or device and add the 2x2 macro widget to the home screen. Make sure macro goals are set, otherwise the fallback path renders the old behaviour.
  4. Open the Dashboard at least once — useWidgetSync is mounted there — and log food against today.
  5. Verify each bar matches the dashboard's per-macro percentage, and that logging something protein-heavy moves the protein bar while carbs and fat stay put. Previously all three shifted as they rebalanced against each other.

Before

The reporter's screenshots in #2228 show the stuck bars: the widget reads 87 g / 184 g / 94 g while the bars sit at their share-of-total positions rather than the dashboard's 81% / 77% / 114%.

After

Verified on an Android emulator: each bar tracks its own goal and matches the dashboard.

Notes for Reviewers

pnpm run validate passes and the mobile suite is green (5884 tests). Verified on an Android emulator.

Coverage note: the behavioural change is split across two layers and only one is testable here. The snapshot payload is covered by useWidgetSync.test.ts, including a regression test that a goal-only change still re-pushes. The Kotlin half has no automated coverage because the repo has no Kotlin test harness, so progressFor was verified by inspection plus the emulator run.

MacroWidget.kt.tmpl is the tracked source for the widget — withCalorieWidget.ts strips the .tmpl suffix and substitutes {{APPLICATION_ID}} during prebuild, and the generated android/ copy is gitignored.

Fallback behaviour worth a second opinion: when a goal is missing the bar keeps the old share-of-total rather than rendering empty. That keeps some signal for users with no goals set, at the cost of two different meanings for the same bar. Rendering empty instead would be more honest but looks broken.

Summary by CodeRabbit

  • New Features

    • Android macro widgets now display progress for protein, carbohydrates, and fat based on their configured daily goals.
    • Macro progress remains available using total consumption when a valid goal is unavailable.
  • Bug Fixes

    • Updated macro goals now immediately refresh the widget with the latest progress and goal values.
    • Improved handling of missing or invalid macro goal values.

The macro widget's three bars rendered each macro's share of total macro
calories rather than progress toward its goal. Those fractions always sum
to one, and a day's macro ratio barely shifts as the day fills up, so the
bars looked frozen while the kcal header moved. With 87g protein, 184g
carbs and 94g fat the bars drew 18/38/44% where the dashboard showed
81/77/114%.

The widget had no way to do better: the snapshot only ever carried
consumed grams, never the goals.

- Send proteinGoal, carbsGoal and fatGoal in the Android macro snapshot.
  The push dedupe key is the stringified snapshot, so a goal-only change
  now re-pushes instead of being skipped
- Draw each bar as consumed/goal, falling back to the old share-of-total
  when a goal is missing, so snapshots written by an older build and
  macros with no goal set degrade instead of collapsing to empty
- Parse the optional doubles through one helper, so absent, JSON null and
  non-finite all read as "not supplied"

The iOS widget keeps the share-of-total maths: it draws one segmented
ring, where three shares summing to one is the intended reading.

📝 Walkthrough

Walkthrough

Android macro snapshots now include protein, carbohydrate, and fat goals. The Android widget parses these goals and uses them for macro progress bars. Tests cover goal serialization and updates triggered by changing only a macro goal.

Changes

Android macro synchronization

Layer / File(s) Summary
Macro goal snapshot payload
SparkyFitnessMobile/src/hooks/useWidgetSync.ts, SparkyFitnessMobile/__tests__/hooks/useWidgetSync.test.ts
The hook defines typed Android snapshot payloads and includes macro goals. Tests verify serialization and a new push when only the protein goal changes.
Goal-based widget progress
SparkyFitnessMobile/targets/android-widget/kotlin/com/sparkyapps/sparkyfitness/widget/MacroWidget.kt.tmpl
MacroSnapshot stores optional goals. Positive finite goals drive clamped progress. Invalid or missing goals use the existing calorie-share fallback.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 0ab38

This change makes Android macro bars track each macro’s goal progress while preserving fallback behavior for missing goals. No actionable merge-blocking risk remains beyond normal checks and review.

Comment thread SparkyFitnessMobile/src/hooks/useWidgetSync.ts Outdated
…itly

Both Android widget payloads were inferred object literals, so a renamed or
dropped field passed typecheck and only surfaced as a widget rendering a
stale or empty value. Typing them turns that into a compile error.

- Add AndroidCalorieSnapshot and AndroidMacroSnapshot, mirroring the keys
  parseSnapshot reads in CalorieWidget.kt.tmpl and MacroWidget.kt.tmpl
- Wrap the pushed payloads in AndroidWidgetPayload<T>, which adds the
  lastUpdated timestamp that is deliberately absent from the dedupe key

This does not make the boundary type-safe: setCalorieSnapshot and
setMacroSnapshot take a string, and the Kotlin readers match these keys by
name, so both halves still have to be kept in step by hand.
