Flutter app for scanner staff at drop-off points, package
ph.verde.verde_scanner. Built on the same foundation as
mobile-driver — Riverpod 2, Dio, go_router, secure_storage —
plus mobile_scanner for native MLKit-backed QR/Code-128 detection.
Backend:
- DropOffPointResource now exposes db_id alongside the public uuid.
The /scanner/scan endpoint takes the integer drop_off_point_id, so
the picker screen needs both to resolve a tap → scan target.
Auth + tenancy (mirrors driver app):
- Tenant gate at /tenant with the same SAN-PASCUAL-BAT shortcut.
- Login validates user.role ∈ { scanner, admin } and stashes the
bearer in keychain.
- ResolveTenant headers attached automatically on every request.
DOP picker (new):
- /dop screen lists drop-off points within 50 km of current GPS,
sorted by distance. Pick one → stored in secure storage as the
active session DOP. The router redirects authenticated scanners
here until they pick.
- GPS prompt screen if location services / permission are missing,
with retry.
Home screen (new):
- "STATIONED AT" banner showing the active DOP with a Change link
that returns to the picker.
- Premium gradient "Start scanning" CTA. Disabled until a DOP is
picked.
- Two stat counters (accepted / total) for the current session.
- Recent scans list with outcome-colored icons.
Camera scan screen (new):
- mobile_scanner with QR + Code-128 formats and noDuplicates speed.
- Verde reticle overlay with corner brackets, dimmed surroundings.
- Bottom translucent banner shows active DOP + accepted count.
- Full-screen toast overlay on every scan: green "Accepted" / amber
"Duplicate" / red "Expired" / red "Invalid" / gray "Network
error". Haptic + system click on accept. 1.5 s cooldown so the
same code can't pump.
- Torch + camera-flip controls top-right.
Data layer:
- DopRepository: GET /drop-off-points/nearby, returns DopOption with
both id and uuid.
- ScanRepository: POST /scanner/scan with current GPS, maps the
backend's "rejected: reason[]" response onto a typed ScanOutcome
(accepted / duplicate / expired / invalid / networkError).
- RecentScansController: in-memory ring buffer capped at 50.
Phase 2 will persist + add an offline buffer.
Permissions:
- iOS Info.plist: NSCameraUsageDescription + NSLocationWhenInUseUsageDescription.
- Android manifest: CAMERA + ACCESS_FINE_LOCATION + INTERNET +
uses-feature camera.
Tests: TenantScreen builds. flutter analyze: 6 style infos, no errors.
