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();
  buffer.writeln('Capability Validation Report:');
  buffer.writeln('  Valid: $isValid');
  buffer.writeln('  Supported: ${supported.length} capabilities');
  buffer.writeln('  Required: ${required.length} capabilities');

  if (missing.isNotEmpty) {
    buffer.writeln('  Missing: ${missing.map((c) => c.name).join(', ')}');
  }

  if (extra.isNotEmpty) {
    buffer.writeln('  Extra: ${extra.map((c) => c.name).join(', ')}');
  }

  return buffer.toString();
}
