- Increase background refresh threshold: Raised the edge distance check in GpsController from 1000m to 2500m to guarantee new Overpass data is fetched well before the user drives out of the cached bounding box.
- Fix bounding box race condition: Added await to the background fetch handler in MapView so tracking bounds only shift forward after the network request successfully finishes.
- Make debounced fetches awaitable: Refactored fetchAndUpdate in NodeProviderWithCache to return a Future<void> using a Completer, bridging the 400ms debounce timer.
- Prevent hanging futures: Added state checks for _activeCompleter to instantly resolve canceled network requests during rapid map panning, preventing fatal StateError crashes and infinite UI hangs.
Tested on a Pixel 10 Pro. These changes were needed to work on real hardware. Also, which background location updating was working, the data was not refreshing in the background. This also adds that. It will pull nodes in a 5km area around your location and update when you within 1km of the area. These values may need to be adjusted if there is increased load on the servers.
- Add ServicePolicy framework with OSM-specific rate limiting and TTL
- Add per-provider disk tile cache (ProviderTileCacheStore) with O(1)
lookup, oldest-modified eviction, and ETag/304 revalidation
- Rewrite DeflockTileProvider with two paths: common (NetworkTileProvider)
and offline-first (disk cache -> local tiles -> network with caching)
- Add zoom-aware offline routing so tiles outside offline area zoom ranges
use the efficient common path instead of the overhead-heavy offline path
- Fix HTTP client lifecycle: dispose() is now a no-op for flutter_map
widget recycling; shutdown() handles permanent teardown
- Add TileLayerManager with exponential backoff retry (2s->60s cap),
provider switch detection, and backoff reset
- Guard null provider/tileType in download dialog with localized error
- Fix Nominatim cache key to use normalized viewbox values
- Comprehensive test coverage (1800+ lines across 6 test files)

Cancel in-progress follow-me animations on pointer-down and suppress
new ones while any pointer is on the map. Without this, GPS position
updates trigger 600ms animateTo() calls that fight with the user's
stationary finger, causing visible wiggle — especially at low zoom
where small geographic shifts cover more pixels.

Change mapBounds from LatLngBounds? to final LatLngBounds so the
compiler can prove it's non-null after the inner try-catch. Addresses
review comment on PR #45.
