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() {
  String s = 'Matrix(\n';
  for (int i = 0; i < nrows; i++) {
    s += _rows[i].toString() + '\n';
  }
  return s + ')';
}
