heading
The heading
read-only property of the GeolocationCoordinates
interface is a double
representing the direction in which the device is
traveling. This value, specified in degrees, indicates how far off from
heading due north the device is. 0
degrees represents true north, and
the direction is determined clockwise (which means that east is 90
degrees and west is 270
degrees). If GeolocationCoordinates.speed is
0
, heading
is NaN
. If the device is not able to provide heading
information, this value is null
.
Implementation
external double? get heading;
