toString method

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 represetion.

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

String toString() {
  StringBuffer sb = new StringBuffer();
  sb.write("SocketException");
  if (message.isNotEmpty) {
    sb.write(": $message");
    if (osError != null) {
      sb.write(" ($osError)");
    }
  } else if (osError != null) {
    sb.write(": $osError");
  }
  if (address != null) {
    sb.write(", address = ${address!.host}");
  }
  if (port != null) {
    sb.write(", port = $port");
  }
  return sb.toString();
}
