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() =>
'${_addIfNotNull('arrival_time', arrivalTime!.millisecondsSinceEpoch)}'
'${_addIfNotNull('departure_time', departureTime!.millisecondsSinceEpoch)}'
'${_addIfNotNull('transit_mode', modes!.map((_) => _.toString()).join('|'))}'
'${_addIfNotNull('transit_routing_preference', routingPreference)}';
