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() {
switch (this) {
case CacheMode.on:
return 'on';
case CacheMode.off:
return 'off';
case CacheMode.cacheOnly:
return 'cache-only';
}
}
