toString method

@override String toString()

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() {
  final start = this.start != null ? this.start.toString() : 'start';
  final end = this.end != null ? this.end.toString() : 'end';
  return 'Segment($line, $start -> $end)';
}
