toString method Null safety

  1. @override
String toString()
override

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() {
  String more;
  try {
    more = ', $asDouble';
  } catch (ignored) {
    final m = asMatrix;
    if (m == null) {
      more = '';
    } else {
      more = ', Matrix ${['A', 'B', 'C', 'D', 'E'][m]}';
    }
  }
  return 'Value(0x${internal.toRadixString(16).padLeft(16, '0')}$more)';
}
