toString method Null safety

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.


String toString() {
  final buffer = StringBuffer();
  var addNewline = false;
  for (final line in response.responseLines) {
    if (addNewline) {
    } else {
      addNewline = true;
    buffer..write(line.code)..write(' ')..write(line.message);
  if (stackTrace != null) {
  return buffer.toString();
