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 contents = [
    if (boolValue != null) 'boolValue=$boolValue',
    if (doubleValue != null) 'doubleValue=$doubleValue',
    if (int64Value != null) 'int64Value=$int64Value',
    if (stringValue != null) 'stringValue=$stringValue',
    if (bytesValue != null) 'bytesValue=$bytesValue',
  ].join(',');
  return 'FeatureValue($contents)';
}
