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() {
String gap(double value) => value.toStringAsFixed(1);
return '$owner: "$text" in ${border.width.round()}×${border.height.round()}: '
'left ${gap(gaps.left)}, top ${gap(gaps.top)}, '
'right ${gap(gaps.right)}, bottom ${gap(gaps.bottom)}';
}
