isWheelchairFriendly property
True when wheelchair access is available for this stop.
Bits 0-1 of stop_details hold the GTFS wheelchair_boarding value
(0 = no info, 1 = accessible, 2 = not accessible); the higher bits are
unrelated stop flags (big stop, transfers, zone ids, ...).
Implementation
bool get isWheelchairFriendly => (_stopDetails & 0x3) == 1;
