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 buffer = StringBuffer();
  buffer.write('[');
  for (var i = 0; i < elements.length; i++) {
    if (elements[i] is String) {
      final value = elements[i].toString().replaceAll("'", r"\'");
      buffer.write("'$value'");
    } else {
      buffer.write(elements[i].toString());
    }
    buffer.write(i < elements.length - 1 ? ', ' : '');
  }
  buffer.write(']');
  return buffer.toString();
}
