toString method Null safety

  1. @override
String toString()
override

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() {
  List<String?> paramsList = [
    '$_format',
    ((_background != null) ? 'b_$_background' : null),
    ((_color != null) ? 'co_$_color' : null)
  ];
  paramsList.add(Flag.waveform().toString());
  return asComponentString(paramsList);
}
