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 parent = super
.toString()
.joinWithValues(['pixelate'], actionSeparator: paramKeyValueSeparator);
if (_region != null) {
if (_region is Faces) {
return parent.joinWithValues([_region],
actionSeparator:
paramKeyValueSeparator).joinWithValues([_squareSize]);
}
return parent +
'_region'.joinWithValues([_squareSize]).joinWithValues([_region],
separator: paramSeparator, actionSeparator: paramSeparator);
}
return parent.joinWithValues([_squareSize]);
}
