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() {
  StringBuffer buffer = StringBuffer();
  if (isSuccess()) {
    buffer.write('Success(');
    buffer.write(data);
  } else {
    buffer.write('Failure($code');
  }
  if (msg != null) buffer.write(', $msg');
  if (requestId != null) buffer.write(', $requestId');
  buffer.write(')');
  return buffer.toString();
}
