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('ImException(code: $code');
  if (message != null && message!.isNotEmpty) {
    buffer.write(', message: $message');
  }
  if (err != null) {
    buffer.write(', err: $err');
  }
  buffer.write(')');
  return message ?? buffer.toString();
}
