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() {
  final sb = StringBuffer('Matrix');
  sb.write(toStringDim);
  if (columns != 0 && rows != 0) {
    sb.writeln(':');
  }
  sb.write(
      formatValueWith((v) => (const FixFloatFormatter(4)).format(v, false)));
  return sb.toString();
}
