`fillControllersFromDish` set the dish's name, four macros and `grams` but left `perGrams` untouched. A `100` left there by an earlier food-bank pick made `nutritionForPortion` read the dish's per-portion macros as per-100g and rescale them: one real entry on 2026-08-23 logged 472 kcal as 1217.8 (258/100). The PC never had this -- `_gatelock_delivery.py` calls `_clear_inputs()` first -- so the fix is that same discipline, as one `MacroControllers.clear()` call rather than a `perGrams.clear()` line a seventh field could forget. `fillFrom` now clears too, and `edit_entry_screen` routes through it instead of six hand-written assignments; its `initState` fill had the same shape. The old tests asserted controller *text* and passed throughout the bug, so the new ones assert the computed `Nutrition` -- verified failing (400 -> 1200.0) before the fix. `clear()` gets an enumerated test so a new field fails until it is cleared too. Also adds the log screen's "Today's delivery" button, matching the PC lock screen's affordance: explicit taps are unguarded per the Triggers table, still skip dishes already logged, and show the queue count. The whole action row moved to its own widget, which put `log_meal_screen.dart` back under the cap. The label is a FittedBox in an Expanded -- measured, since a Row clips an oversized label without ever throwing.

diet_guard_app
Companion app for diet_guard: log meals on the phone, and on the Linux
desktop, sharing one food log through GitHub-backed sync.
Two targets, and only two
| Target | What it is |
|---|---|
| Android | a normal Flutter app (flutter build apk) |
| Linux desktop | the Flutter web build, served by a local wrapper and shown in a Chrome --app window |
There is no linux/ directory. Flutter's GTK embedder manages ~20fps at
3840x2160 -- measured on a stock flutter create counter app, so it is the
toolkit rather than this code -- where the same Dart rendered by Chrome
sustains ~144fps (~/todo/docs/desktop-performance-findings.md). Running
flutter create --platforms linux here would silently restore the slow path.
Commands
flutter test # the app's suite
flutter analyze
bash run.sh # build the web bundle and launch the desktop app
bash install_arch.sh # build + install the pacman package and .desktop entry
flutter build apk --release # the phone build
adb install -r build/app/outputs/flutter-apk/app-release.apk
Never adb uninstall or pm clear this package: both wipe the on-device log.
The desktop wrapper
bin/diet_guard_desktop.dart is the other half of the desktop app, because a
browser cannot touch the filesystem. It:
- serves the built web assets from
build/web(or/opt/diet-guard-app/webonce packaged); - keeps an on-disk copy of every document and photo under
~/.local/share/diet-guard-desktop/, which is what makes a wiped Chrome profile recoverable -- for photos it is the only copy, since they never sync; - holds the GitHub token (
~/.config/diet_guard_app/sync_token, falling back to the PC gate's~/.config/diet_guard/sync_token) and proxiesapi.github.complus the device flow, whose endpoints send no CORS headers and so cannot be called from a page at all.
The port (8732) and the Chrome --user-data-dir must stay fixed.
IndexedDB is keyed by origin and lives inside that profile, so changing either
looks to the app like a device with no history.
Platform seams
dart:io does not fail a web compile; it becomes a stub that throws at
runtime, so the symptom of a missed seam is a blank white window rather than a
build error. Every platform edge is a conditional export -- document_store*,
blob_store*, background_tasks*, notification_backend*, token_vault*,
github_client_factory*, attached_image*. Branch on kIsWeb before any
Platform.is…, which itself throws on web.
What the desktop genuinely loses, by design rather than omission:
- Background reminders. A browser runs nothing once its window is closed,
so the due-slot check runs in-page every 5 minutes while the window is open.
On the PC the real backstop is
diet-guard-gate.timer, which locks the screen. - Camera capture. The browser picker is a file input.
- Photo sharing between devices -- unchanged:
imagePathwas always stripped before push.
Sync identity
Three devices push under diet-guard-sync/devices/: pc (the Python gate),
phone, and desktop. Each must keep its own id -- two devices sharing one
would overwrite each other's pushed log on every tick.
