# 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() {
      if (isEmpty) return '[]';
      final buffer = StringBuffer('[');
      _Node<E>? current = _head;
      while (current != null) {
        buffer.write(current.value);
        if (current.next != null) {
          buffer.write(', ');
        }
        current = current.next;
      }
      buffer.write(']');
      return buffer.toString();
    }
