toString method

  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() {
  final formattedString = val.toString();
  var split = formattedString.split('.');
  if (microsecond > 0) {
    split[1] = split[1].replaceFirst('Z', '');
    String microsecondsStr = microsecond.toString().padLeft(3, '0');
    if (microsecondsStr.length < 3) {
      microsecondsStr = microsecondsStr.padLeft(
        3 - microsecondsStr.length,
        '0',
      );
    }

    split[1] = split[1].substring(0, 3) + microsecondsStr;
    var result = '${split.join('.')}Z';
    return result;
  }

  return formattedString;
}
