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('AsyncError: $code - $message');
  if (sqlState != null) buffer.write(' (SQLSTATE: $sqlState)');
  if (nativeCode != null) buffer.write(' (Native: $nativeCode)');
  return buffer.toString();
}
