toString method Null safety

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.


String toString() {
  final block = style.value(NotusAttribute.block);
  final buffer = StringBuffer('§ {$block}\n');
  for (var child in children) {
    final tree = child.isLast ? '└' : '├';
    buffer.write('  $tree $child');
    if (!child.isLast) buffer.writeln();
  return buffer.toString();
