setPolygon method

  1. @override
bool setPolygon(
  1. LocationPolygon polygon
)
override

Method is used to specify the source polygon of the object. polygon Metrics coordinates of the polygon LocationPolygon. Returns true if success, false otherwise.

Example:

// Set polygon geometry
List<Point> points = [
 Point(100.0, 200.0),
 Point(150.0, 250.0),
 Point(200.0, 200.0),
 Point(150.0, 150.0),
];
Polygon metricPolygon = Polygon(points);
LocationPolygon polygon = LocationPolygon(metricPolygon, 1, 0);
bool success = _polygonMapObject!.setPolygon(polygon);
print("Set polygon with ${points.length} points: $success");

Implementation

@override
bool setPolygon(LocationPolygon polygon) {
    final _setPolygonFfi = __lib.catchArgumentError(() => __lib.nativeLibrary.lookupFunction<
        Uint8 Function(Pointer<Void>, Pointer<Void>),
        int Function(Pointer<Void>, Pointer<Void>)
      >('navigine_sdk_flutter_PolygonMapObject_setPolygon__Polygon'));
    final _polygonHandle = navigine_sdk_flutter_LocationPolygon_ToFfi(polygon);
    final _handle = this.handle;
    final __resultHandle = _setPolygonFfi(_handle, _polygonHandle);
    navigine_sdk_flutter_LocationPolygon_ReleaseFfiHandle(_polygonHandle);
    final _result = navigine_sdk_flutter_bool_FromFfi(__resultHandle);
    navigine_sdk_flutter_bool_ReleaseFfiHandle(__resultHandle);
    return _result;
}
