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 sb = StringBuffer();
  final length = expressions.length;
  for (var i = 0; i < length; i++) {
    final expression = expressions[i];
    sb.write(expression);
    if (i < length - 1) {
      sb.write(' ');
    }
  }

  return sb.toString();
}
