isAllTime property

  1. @override
bool get isAllTime
override

true if this date range represents all available history.

All time ranges might be handled specially by backends. For instance, Shasta has preaggregated all time stats tables, so queries are a lot faster if it knows the all-time-ness of a range, instead of just the start and end dates.

Implementation

@override
bool get isAllTime => false;
