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 str = StringBuffer();
  inputs?.forEach((i) => str.write(i.toString() + ','));
  str.write(' => ');
  for (final i in outputs) {
    str.write(i.toString() + ',');
  }
  return str.toString();
}
