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 parts = <String>[];
  if (sources.isNotEmpty) {
    parts.add('sources: ${sources.length}');
  }
  if ($directives != null && $directives!.isNotEmpty) {
    parts.add('directives: ${$directives!.length}');
  }

  return '$runtimeType(${parts.join(', ')})';
}
