Methods

isPointInside(List<double> point) → bool
Determines if a point is inside
isPointInsideComplex(List<double> point) → bool
Checks if a point is within a complex polygon, considering the outer boundary and any inner holes.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
optimalPointInside({double resolution = 2.0}) → List<double>
Calculates the optimal point within a complex polygon using a custom grid-based search algorithm.
toJSON({int indent = 0}) → String
Converts the object to a JSON string representation.
override
toMap() → Map<String, dynamic>
Converts GeoJSON object to a Map.
override
toString() → String
A string representation of this object.
