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() {
final text = compositionNode.toString();
// Remove outer parentheses for clarity and because they're unnnecessary.
if (text.startsWith("(") && text.endsWith(")") && text.length > 2) {
return text.substring(1, text.length - 1);
} else {
return text;
}
}
