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() {
  if (curve is! _Linear) {
    return '${objectRuntimeType(this, 'Interval')}($begin\u22EF$end)\u27A9$curve';
  }
  return '${objectRuntimeType(this, 'Interval')}($begin\u22EF$end)';
}
