toString method

  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 StringBuffer buffer = StringBuffer();
  for (final List<int> i in grid) {
    for (final int j in i) {
      buffer.write("${Colorize("o").apply(colors[j]!)} ");
    }
  }

  return buffer.toString();
}
