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() =>
    'Invalid Value type. \nSupported types are "String", "Map<String, dynamic>",List<dynamic>, "bool" or "num"'
    '\n For Maps and Lists, the values should conform to the types stated above';
