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 'Instruction{points: $points, annotation: $annotation, sign: $sign, name: $name, distance: $distance, time: $time, extraInfoJSON: $extraInfoJSON, length: $length}';
}
