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 array:
return 'array';
case boolean:
return 'boolean';
case integer:
return 'integer';
case number:
return 'number';
case nullValue:
return 'null';
case object:
return 'object';
case string:
return 'string';
}
return '<unknown>';
}
