PositionDataDeliveryPolicy class Sensor Data Source
Delivers a position update when the position changes meaningfully.
Works with DataType.position and DataType.improvedPosition. An update is delivered when any one of these happens: the fix quality changes, the position moves by at least minDistanceMeters, the speed changes by at least minSpeedChange, or the course changes by at least minCourseChangeDegrees. With no threshold set, throttleInterval alone decides.

Static Methods
-
create(
{required DataType dataType, Duration throttleInterval = Duration.zero, double minDistanceMeters = 0, double minSpeedChange = 0, double minCourseChangeDegrees = 0, bool deliverOnFixQualityChange = true}) → PositionDataDeliveryPolicy? -
Create a policy for
dataType, which must be DataType.position or DataType.improvedPosition.override
