search method
Returns all items whose rectangles overlap searchRect
If shouldInclude
is specified, each item will be passed to the
method and excluded if shouldInclude
evaluates to false.
Note: Rectangles that share only a border are not considered to overlap
Implementation
List<RTreeDatum<E>> search(Rectangle searchRect, {bool Function(E item)? shouldInclude}) {
shouldInclude ??= (_) => true;
if (_root is LeafNode<E>) {
return _root.search(searchRect, shouldInclude);
}
return _root.search(searchRect, shouldInclude);
}
