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 sb = StringBuffer();
  sb.write('Affine:\n');
  for (int r = 0; r < 3; r++) {
    for (int c = 0; c < 3; c++) {
      sb.write('\t${get(r, c)}');
    }
    sb.write('\n');
  }
  return sb.toString();
}
