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
String toString() {
var result = clauses
.mapIndexed((index, clause) =>
"@${index == 0 ? 'if' : 'else if'} ${clause.expression} "
"{${clause.children.join(' ')}}")
.join(' ');
var lastClause = this.lastClause;
if (lastClause != null) result += " $lastClause";
return result;
}
