toString method

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() {
  var b = StringBuffer()
    ..write('HttpException: ')
  var uri = this.uri;
  if (uri != null) {
    b.write(', uri = $uri');
  return b.toString();
