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() {
  switch (type) {
    case BoundType.inclusive:
      return '$value]';
    case BoundType.exclusive:
      return '$value)';
    case BoundType.unbounded:
      return ')';
    default:
      assert(false, 'unknown bound type ($type)');
      return '';
  }
}
