toString method
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() => (ClassToString('Location')
..add('address', _self.address)
..add('displayName', _self.displayName)
..add('id', _self.id)
..add('livemode', _self.livemode)
..add('metadata', _self.metadata))
.toString();
