Dart implementation of the bdcc GeoDistanceAlgorithm. The algorithm calculates if a single coordinate is near a polyline path in a given radius. This can be used to detect when it is a good moment to recalculate a route in navigation.
This package has the following method:
isLocationOnPathWithRadius(List<LatLng> polyline, LatLng point, int radius)
returnstrue
if the distance frompoint
topolyline
is at leastradius
meters, andfalse
if it is not.
if (isLocationOnPathWithRadius(ppoints, currentPosition, 20)) {
// continue
} else {
// recalculates the route
}
