toString method

@override String toString({ int? precision, })

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({int? precision}) {
  final p = precision ?? 2;
  final sign = _im >= 0 ? '+' : '-';
  return '${_re.toStringAsFixed(p)} $sign ${_im.abs().toStringAsFixed(p)}i';
}
