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 buffer = StringBuffer();
  if (type == xsDate) {
    _writeYear(buffer, year ?? 1970);
    buffer.write('-');
    buffer.write((month ?? 1).toString().padLeft(2, '0'));
    buffer.write('-');
    buffer.write((day ?? 1).toString().padLeft(2, '0'));
  } else if (type == xsTime) {
    _writeTime(buffer);
  } else if (type == xsGYearMonth) {
    _writeYear(buffer, year ?? 1970);
    buffer.write('-');
    buffer.write((month ?? 1).toString().padLeft(2, '0'));
  } else if (type == xsGYear) {
    _writeYear(buffer, year ?? 1970);
  } else if (type == xsGMonthDay) {
    buffer.write('--');
    buffer.write((month ?? 1).toString().padLeft(2, '0'));
    buffer.write('-');
    buffer.write((day ?? 1).toString().padLeft(2, '0'));
  } else if (type == xsGMonth) {
    buffer.write('--');
    buffer.write((month ?? 1).toString().padLeft(2, '0'));
  } else if (type == xsGDay) {
    buffer.write('---');
    buffer.write((day ?? 1).toString().padLeft(2, '0'));
  } else {
    // xsDateTime, xsDateTimeStamp
    _writeYear(buffer, year ?? 1970);
    buffer.write('-');
    buffer.write((month ?? 1).toString().padLeft(2, '0'));
    buffer.write('-');
    buffer.write((day ?? 1).toString().padLeft(2, '0'));
    buffer.write('T');
    _writeTime(buffer);
  }
  buffer.write(_formatTimezone());
  return buffer.toString();
