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>[];
  parts.add(valid ? 'Valid' : 'Invalid');
  for (final e in errors) {
    parts.add('  ERROR: $e');
  }
  for (final w in warnings) {
    parts.add('  WARN: $w');
  }
  return parts.join('\n');
}
