globalToLocal method
Converts the point object from the Stage
's global coordinates to this
display object's local coordinates.
This method allows you to convert any given x- and y-coordinates from
values that are relative to the origin (0,0) of the Stage
's global
coordinates to values that are relative to the origin of this display
object's local coordinates.
Implementation
Point<num> globalToLocal(Point<num> globalPoint, [Point<num>? returnPoint]) {
final p = returnPoint is Point ? returnPoint : Point<num>(0.0, 0.0);
p.x = globalPoint.x.toDouble();
p.y = globalPoint.y.toDouble();
_globalToLocalRecursion(p);
return p;
}
