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() {
  if (issues.isEmpty) return 'ValidationResult: OK';
  return 'ValidationResult(${errors.length} errors, '
      '${warnings.length} warnings):\n'
      '${issues.map((i) => '  $i').join('\n')}';
}
