toString method

@override String toString({ int precision = 4, })

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({int precision = 4}) {
  if (length == 0) {
    return '{empty}';
  }

  var minStr = formatDecimal(min, precision: precision);
  var maxStr = formatDecimal(max, precision: precision);
  var centerStr = formatDecimal(center, precision: precision);

  var meanStr = formatDecimal(mean, precision: precision);
  var standardDeviationStr =
      formatDecimal(standardDeviation, precision: precision);

  return '{~$meanStr +-$standardDeviationStr [$minStr..($centerStr)..$maxStr] #$length}';
}
