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 StringBuffer buffer = StringBuffer(message);
if (element case final Element element?) {
try {
final SourceSpan span = spanForElement(element);
buffer
..writeln()
..writeln(span.start.toolString)
..write(span.highlight());
} catch (e) {
buffer
..writeln()
..writeln('Cause: ${element.runtimeType} : ${element.name}');
}
}
if (node case final AstNode node?) {
try {
final SourceSpan span = spanForNode(node);
buffer
..writeln()
..writeln(span.start.toolString)
..write(span.highlight());
} catch (_) {
buffer
..writeln()
..writeln('Cause: $node');
}
}
return buffer.toString();
}
