isLocationOnEdge static method
Computes whether the given point lies on or near the edge of a polygon, within a specified tolerance in meters. The polygon edge is composed of great circle segments if geodesic is true, and of Rhumb segments otherwise. The polygon edge is implicitly closed - the closing segment between the first point and the last point is included.
Implementation
static bool isLocationOnEdge(
LatLng point, List<LatLng> polygon, bool geodesic,
{num tolerance = defaultTolerance}) =>
_isLocationOnEdgeOrPath(point, polygon, true, geodesic, tolerance);
