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() =>
'SharePayload(family: $familyId, v$engineVersion, '
'seed: 0x${seed.toRadixString(16)}'
'${intent == null ? '' : ', $intent'}${centred ? ', centred' : ''})';
