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() => [
      'SumInterface[$width]',
      if (fixedAmount != null) ' = $fixedAmount',
      if (increments) ' ++ ' else ' -- ',
      if (hasEnable) ' (enable)',
    ].join();
