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