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 represetion.

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 List<String> arguments = <String>[
    if (top != BorderSide.none) 'top: $top',
    if (start != BorderSide.none) 'start: $start',
    if (end != BorderSide.none) 'end: $end',
    if (bottom != BorderSide.none) 'bottom: $bottom',
  ];
  return '${objectRuntimeType(this, 'BorderDirectional')}(${arguments.join(", ")})';
}
