Running the app on an emulator for the first time showed two problems that the unit tests could not have caught, because both are about what the pixels actually do. The configured initial zoom of 7.2 puts the viewport entirely inside the region on a 411dp-wide screen, so the map rendered as a flat expanse of fill colour with no outline, border or reference point anywhere in view — it read as a failure to load. A single zoom number cannot frame a region on both a phone and a tablet, so the camera now fits the region bounds once the map is ready, which is correct at any screen size. The configured zoom stays as the starting position before the fit. The attribution bar sat behind the system gesture pill. A credit that is covered by the navigation bar is a credit that is not being displayed, which is the thing ODbL and CC BY-SA actually require, so it now sits inside a SafeArea. Also records how to run and screenshot the app on the `nuvolari` AVD, and notes the pre-existing broken `pixel_7_-_api_35` AVD that is holding 4.8 GB. Verified on the emulator: the region outline is framed with margin, the attribution bar is clear of the pill, and the Sources screen shows the disclaimer, all four credits with their licences, the "no licence stated" line for ARPA and the share-alike note.

# Roadmap
|
|
|
|
Each milestone ends with `tool/verify.ps1` green and one commit. A milestone is not
|
|
done until its acceptance criteria hold.
|
|
|
|
Legend: ✅ done · 🔨 in progress · ⛔ blocked on credentials from the project owner
|
|
|
|
---
|
|
|
|
## M0 — Toolchain and repository hygiene ✅
|
|
|
|
Flutter 3.47.3 stable, Android SDK (platform-tools, platform 36, build-tools 36.0.0),
|
|
JDK 21, environment variables. Commit the removal of the old Xamarin skeleton.
|
|
|
|
**Accepts when:** `flutter doctor -v` reports no blocking Android toolchain error and
|
|
`git status` is clean.
|
|
|
|
**Done.** `flutter doctor -v` reports "No issues found!". Installed: Flutter 3.47.3 at
|
|
`C:\src\flutter` (telemetry disabled), Android SDK at `C:\Android\Sdk` with
|
|
platform 36, build-tools 36.0.0, platform-tools and all licences accepted, and
|
|
`JAVA_HOME` pointing at the JDK 21 a previous Visual Studio install had already left
|
|
on the machine.
|
|
|
|
## M1 — Scaffold, Italian l10n, region config, CI ✅
|
|
|
|
`flutter create` with applicationId `it.nuvolari.app`; `flutter_localizations` + `intl`
|
|
with `app_it.arb` as template and no hardcoded UI strings; `RegionConfig` loaded from
|
|
`assets/regions/piemonte.json` with parsing tests; `.gitignore`, `env.example.json`,
|
|
`tool/verify.ps1`, `.gitea/workflows/ci.yml`.
|
|
|
|
**Accepts when:** `flutter analyze` reports 0 issues, `flutter test` passes,
|
|
`flutter build appbundle --debug` succeeds.
|
|
|
|
**Done.** All four stages green; the AAB carries applicationId `it.nuvolari.app`,
|
|
minSdk 24, targetSdk 36. 50 tests, including assertions against the shipped Piemonte
|
|
asset and a captured copy of the live ARPA CAP feed.
|
|
|
|
> The Gitea instance may have no Actions runner. The workflow file is written to be
|
|
> GitHub-Actions compatible, but `tool/verify.ps1` is the verification that must pass.
|
|
|
|
## M2 — Map, attribution, Sources screen ✅
|
|
|
|
MapLibre with the style from `MAP_STYLE_URL`, falling back to a local minimal style.
|
|
Permanent OSM/ODbL attribution. Sources / Licenses / Disclaimer screen covering
|
|
Radar-DPC (CC BY-SA), MET Norway, ARPA, OSM, with the explicit "not an official app"
|
|
disclaimer.
|
|
|
|
**Accepts when:** the map opens centred on Piedmont, attribution is visible at all
|
|
times, and the Sources screen is reachable and complete.
|
|
|
|
**Done**, with one gap. The fallback style is generated from the region bounding box
|
|
rather than loaded from an asset, so it needs no third-party boundary dataset and no
|
|
network. The attribution bar lists only the sources actually rendered — crediting
|
|
OpenStreetMap while showing the fallback would be a false attribution — and sits below
|
|
the map rather than floating over it so no map control can occlude it.
|
|
|
|
**Verified on an emulator** (`nuvolari`, API 36.1, x86_64, GPU host). Running it caught
|
|
two things the unit tests could not: the configured initial zoom put the viewport
|
|
entirely inside the region so the map read as a blank expanse, and the attribution bar
|
|
sat behind the system gesture pill. Both fixed — the camera now fits the region bounds
|
|
at runtime, which works on any screen size, and the bar is inside a SafeArea.
|
|
|
|
## M3 — Animation and timeline 🔨
|
|
|
|
`RadarSource` with `MockRadarSource` (synthetic frames in assets) and `DpcRadarSource`.
|
|
Timeline scrubber, play/pause, adjacent-frame prefetch, `FrameCache` LRU, animation
|
|
suspended in background, graceful degradation with a data-age banner.
|
|
|
|
**Accepts when:** animation runs smoothly in demo mode **with the network off**, and
|
|
prefetch, LRU eviction and the fallback paths are covered by tests.
|
|
|
|
## M4 — Forecast
|
|
|
|
`MetNoForecastSource` with the mandatory identifying User-Agent, honouring `Expires`
|
|
and `If-Modified-Since`. `IconIt2Source` as a flagged fallback. Hourly and daily views.
|
|
|
|
**Accepts when:** a forecast renders for a Piedmont location, caching respects the
|
|
response headers, and fixture-based tests pass.
|
|
|
|
## M5 — UMP consent and AdMob ⛔
|
|
|
|
UMP consent form before any ad request; non-personalised ads when consent is declined.
|
|
Anchored adaptive banner — never over the map, never an interstitial during animation.
|
|
**Test ad unit IDs only** until real ones are supplied.
|
|
|
|
**Blocked on:** AdMob App ID and ad unit IDs.
|
|
|
|
## M6 — Rain notifications and alerts ⛔
|
|
|
|
`ArpaCapAlertSource` reading the CAP feed through the backend; zones `Piem-A`…`Piem-M`
|
|
with levels shown verbatim and a link to the official bulletin. Rain notifications via
|
|
FCM topics per geographic cell, subscribed from the device.
|
|
|
|
**Blocked on:** Firebase project and `google-services.json`.
|
|
|
|
## M7 — Android home widget
|
|
|
|
Glance widget showing the latest frame and the next rain, refreshed by WorkManager.
|
|
|
|
**Accepts when:** the widget renders a real frame on the home screen and updates.
|
|
|
|
## M8 — Backend worker ⛔
|
|
|
|
`dpc_client` (with the `origin` header), `crop` (bbox + reproject to EPSG:3857),
|
|
`palette` (dBZ colormap, legend exported into the manifest), `render` (RGBA PNG,
|
|
transparent below threshold), `manifest`, and `publisher/` with `LocalPublisher` and
|
|
`S3Publisher`. WebSocket trigger with cron fallback. pysteps nowcast present but
|
|
disabled behind a flag.
|
|
|
|
**Accepts when:** `python -m pytest` passes and one full run produces PNGs plus a
|
|
`manifest.json` that the app consumes from a local server.
|
|
|
|
**Blocked on (publishing only):** VPS / object storage endpoint and credentials.
|
|
Development proceeds against `LocalPublisher`.
|
|
|
|
## M9 — Play Store release preparation ⛔
|
|
|
|
Signing config reading `key.properties`, release AAB, target API 36, privacy policy
|
|
draft, store listing copy, Data safety draft, prominent disclosure for location.
|
|
|
|
**Blocked on:** upload keystore and Play Console account.

## Verifying on the emulator
|
|
|
|
An AVD named `nuvolari` is set up on this machine: API 36.1, `google_apis`, x86_64,
|
|
GPU passthrough to the host. It uses a 2 GB data partition and no SD card because disk
|
|
is tight.
|
|
|
|
```bash
|
|
# Boot it
|
|
"$ANDROID_HOME/emulator/emulator" -avd nuvolari -no-audio -no-boot-anim -gpu host
|
|
|
|
# Build, install, launch
|
|
cd app
|
|
flutter build apk --debug
|
|
adb install -r build/app/outputs/flutter-apk/app-debug.apk
|
|
adb shell am start -n it.nuvolari.app/.MainActivity
|
|
|
|
# Capture what it looks like
|
|
adb exec-out screencap -p > screen.png
|
|
```
|
|
|
|
`flutter run -d emulator-5554` works too and gives hot reload; the steps above are what
|
|
a non-interactive session uses.
|
|
|
|
> An unrelated AVD, `pixel_7_-_api_35`, is present but broken — its system image
|
|
> (`android-35/google_apis_playstore`) is not installed, so it cannot boot. It occupies
|
|
> about 4.8 GB. It predates this project and has been left alone.
