toString method

  1. @override
String toString()
override

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 String valueString = T == String ? "<'$value'>" : '<$value>';
  // The crazy on the next line is a workaround for
  // https://github.com/dart-lang/sdk/issues/33297
  if (runtimeType == _TypeLiteral<ValueKey<T>>().type) {
    return '[$valueString]';
  }
  return '[$T $valueString]';
}
