Office data pipeline

The app’s office/mailbox list is bundled as a static asset: assets/lm_offices.json. It’s loaded once at runtime by OfficeService.loadOffices() and never fetched from the network, so the app works fully offline once the user’s coordinates are known.

Format

Each entry maps to an Office:

{
  "name": "LM Plus Aalst",
  "address": "Capucienenlaan 93 E",
  "city": "Aalst",
  "postal_code": "9300",
  "phone": "053 21 58 16",
  "lat": 50.9338912,
  "lng": 4.0295921,
  "type": "office",
  "opening_hours": {
    "1": [[900, 1200], [1300, 1630]],
    "2": [[900, 1200]],
    "6": [],
    "0": []
  }
}

• type is "office" or "mailbox" (mailboxes typically have no opening_hours).
• opening_hours maps weekday ("0" = Sunday .. "6" = Saturday) to a list of [start, end] time slots in HHMM integer form (e.g. 900 = 09:00). An empty list means closed all day. A missing entry means “unknown” (e.g. by-appointment offices).

Regenerating the data

Two Python scripts in scripts/ scrape https://www.lm-ml.be/nl/kantoren (31 pages, 12 offices/page):

Script	Use it to…	What it touches
scrape_offices.py	Do a full rebuild	Scrapes everything (name/address/phone/type/hours) and geocodes each address via Nominatim. Slow (one geocoding request per office, rate-limited), only needed when offices are added, removed, or moved.
update_office_metadata.py	Refresh type & opening hours	Re-scrapes the listing pages and merges just type/opening_hours into the existing JSON by matching on name/address/postal code/city. Leaves coordinates untouched, much faster, safe to re-run periodically.

Both write back to assets/lm_offices.json. Run with:

python scripts/scrape_offices.py
# or, for a lighter refresh:
python scripts/update_office_metadata.py

Requires requests and (for the full scrape) beautifulsoup4.

App icon

scripts/generate_app_icon.py draws the app icon (a navy map-pin “blob” with a light-blue ”+”) and writes assets/icon/icon.png and assets/icon/icon_foreground.png. After running it, regenerate the platform-specific icons with:

dart run flutter_launcher_icons
