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 (isZero) return '0';
  if (isNegative) {
    final mag =
        (~_bits) +
        Uint64.one; // correct even at Int64.min: wraps to itself, i.e. 2^63
    return '-${mag.toString()}';
  }
  return _bits.toString();
}
