toString method
override
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() {
if (reverseCurve == null) {
return '$parent\u27A9$curve';
}
if (_useForwardCurve) {
return '$parent\u27A9$curve\u2092\u2099/$reverseCurve';
}
return '$parent\u27A9$curve/$reverseCurve\u2092\u2099';
}
