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() {
  return 'Your cache document does not exist on Firestore, which means you '
      'will always be fetching your documents from the server. Create your '
      'cache document on Firestore first with your specified field name of a '
      'timestamp.';
}
