- 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.
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.
