toString method

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

String toString() {
  var components = [
    for (var argument in positional) _parenthesizeArgument(argument),
    for (var (name, value) in named.pairs)
      "\$$name: ${_parenthesizeArgument(value)}",
    if (rest case var rest?) "${_parenthesizeArgument(rest)}...",
    if (keywordRest case var keywordRest?)
      "${_parenthesizeArgument(keywordRest)}..."
  ];
  return "(${components.join(', ')})";
}
