project method
Returns an object of the same subtype as this with all position data
projected using projection
and non-positional properties left intact.
If bounds object is available on this, then it's not projected and the returned object has it set null.
Examples:
// just project, the returned object has not bounds populated
someBoundedObject.project(someProjection);
// project and populate, the returned object has bounds populated
someBoundedObject.project(someProjection).populated(onBounds: true);
Implementation
@override
MultiLineString project(Projection projection) {
final projected = _lineStrings
.map((chain) => chain.project(projection))
.toList(growable: false);
return MultiLineString(projected);
}
