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() {
var result = super.toString();
if (queryString != null) {
if (errorPosition != null) {
result +=
'\n${highlightPosition(queryString!, offset: errorPosition!)}';
} else {
result += '\n$queryString';
}
}
return result;
}
