toString method
A string representation of this object.
Some classes have a default textual representation,
often paired with a static parse function (like int.parse).
These classes will provide the textual representation as
their string representation.
Other classes have no meaningful textual representation
that a program will care about.
Such classes will typically override toString to provide
useful information when inspecting the object,
mainly for debugging or logging.
Implementation
@override
String toString() {
return 'SpatialIndexStats('
'objects: $objectCount, '
'gridCells: $gridCellCount, '
'dragging: $isDragging, '
'draggingObjects: $draggingObjectCount, '
'cacheSize: $cacheSize)';
}
