NextSpeedLimit class Routes & Navigation

Speed limit variation data.

Encapsulates information about upcoming speed limit changes during navigation, including the geographic coordinates where the change occurs, the distance to the change, and the new speed limit value.

Properties

  • coords: Geographic coordinates where the speed limit change begins.
  • distance: Distance (in meters) from current position to the speed limit change.
  • speed: New speed limit value (in current unit system).
  • status: Availability status of the speed limit data (computed property).

Usage

This class is returned by NavigationInstruction.getNextSpeedLimitVariation and should not be instantiated directly. Use the status property to determine how to interpret the data.

Constructors

NextSpeedLimit.new({required Coordinates coords, required int distance, required double speed})
NextSpeedLimit.fromJson(Map<String, dynamic> json)
Returns a simplified turn icon for the upcoming maneuver. For a detailed geometry image, use nextTurnDetails.abstractGeometryImg. Returns null Deserializes a JSON-compatible map to create an instance.
