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('ValidationException: $message');
  if (violations.isNotEmpty) {
    buffer.write('\nViolations:');
    for (final violation in violations) {
      buffer.write('\n  - ${violation.field}: ${violation.message}');
    }
  }
  return buffer.toString();
}
