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() {
// TODO: implement toString
return {
'point':[point?.x,point?.y,point?.z],
'normal': [normal.x,normal.y,normal.z],
'depth':depth
}.toString();
}
