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() {
  return "${_rectangular ? "Rectangular Symbol:" : "Square Symbol:"}"
      ' data region $matrixWidth'
      'x$matrixHeight'
      ', symbol size $symbolWidth'
      'x$symbolHeight'
      ', symbol data size $symbolDataWidth'
      'x$symbolDataHeight'
      ', codewords $_dataCapacity'
      '+$_errorCodewords';
}
