intersects method

bool intersects(Polygon poly)

Returns whether the two Polygons intersect. Uses the toLineString to check for intersections, rather than checking for shared volume.

Example:

Polygon poly1 = Polygon([
  LinearRing([
    Coordinate(0, 0),
    Coordinate(0, 1),
    Coordinate(1, 1),
    Coordinate(1, 0),
    Coordinate(0, 0),
  ]),
]);
Polygon poly2 = Polygon([
  LinearRing([
    Coordinate(0.5, 0.5),
    Coordinate(0.5, 1.5),
    Coordinate(1.5, 1.5),
    Coordinate(1.5, 0.5),
    Coordinate(0.5, 0.5),
  ]),
]);
print(poly1.intersects(poly2)); // true

Implementation

bool intersects(Polygon poly) {
  return toLineString()
      .intersections(poly.toLineString())
      .features
      .isNotEmpty;
}
