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() {
return '''
groupItemsSelect: ${groupItemsSelect},
hasGroups: ${hasGroups},
itemsSelect: ${itemsSelect},
rotation: ${rotation},
values: ${values},
getValues: ${getValues},
getValue: ${getValue}
''';
}
