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() {
  final buffer = StringBuffer();
  final parts = <dynamic>[];

  if (isSuccess()) {
    buffer.write('Success(');
    if (data != null) {
      parts.add(data);
    }
  } else {
    buffer.write('Failure(');
    parts.add(code);
  }

  if (msg != null) parts.add(msg);
  if (requestId != null) parts.add(requestId);

  buffer.write(parts.join(', '));
  buffer.write(')');
  return buffer.toString();
}
