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 g = groups.map(_convert).join(', ');
return 'TextElement('
'matcherType: $matcherType, '
'matcherIndex: $matcherIndex, '
'offset: $offset, '
'text: ${_convert(text)}, '
'groups: [$g]'
')';
}
