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() {
  if (isEmpty) {
    return 'NIL';
  }
  final standardValues = [
    name,
    version,
    os,
    osVersion,
    vendor,
    supportUrl,
    address,
    date,
    command,
    arguments,
    environment,
  ];
  final buffer = StringBuffer()..write('(');
  var addSpace = false;
  for (var i = 0; i < standardValues.length; i++) {
    final value = standardValues[i];
    if (value != null) {
      if (addSpace) {
        buffer.write(' ');
      } else {
        addSpace = true;
      }
      final name = _standardFieldNames[i];
      buffer
        ..write('"')
        ..write(name)
        ..write('" ')
        ..write('"')
        ..write(value)
        ..write('"');
    }
  }
  buffer.write(')');
  return buffer.toString();
}
