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() {
  if (_type != null && _height.value != null) {
    return '$_cover at ${heightInFeet!.toStringAsFixed(1)} feet of $_type';
  }

  if (_height.value != null) {
    return '$_cover at ${heightInFeet!.toStringAsFixed(1)} feet';
  }

  final undefinedCovers =
      <String>['NSC', 'NCD', '///'].map((el) => skyCover[el]).toList();
  if (undefinedCovers.contains(_cover)) {
    return '$_cover';
  }

  if (_cover == skyCover['VV']) {
    if (_height.value != null) {
      return '$_cover at ${heightInFeet!.toStringAsFixed(1)} feet';
    }
    return '$_cover';
  }

  return '$_cover at undefined height';
}
