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 header = [
    instructionClass,
    instructionCode,
    p1Parameter,
    p2Parameter,
  ].map((b) => b.toRadixString(16).padLeft(2, '0')).join(' ');
  final body = data;
  return 'CommandApdu($header, ${body == null ? 'no data' : '${body.length} bytes'}, '
      'Le ${expectedResponseLength ?? 'none'}${isExtended ? ', extended' : ''})';
}
