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 params = [
    ...parameterNames,
    if (namedParameterNames.isNotEmpty) '{${namedParameterNames.join(', ')}}',
  ].join(', ');
  final returnStr = returnType != null ? ' -> $returnType' : '';
  final asyncStr = isAsync ? 'async ' : '';
  final genStr = isGenerator ? '* ' : '';
  return '$asyncStr${genStr}function $name($params)$returnStr';
}
