Methods

toJson

1. @override

Map<String, dynamic> toJson()

override

Return a JSON encoding of this object.

toString

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.
