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() {
  final fields = toStringFields.entries
      .where((field) => field.value != null)
      .map((field) => ', ${field.key}: ${field.value}')
      .join();
  return '$runtimeType($queryKey$fields)';
}
