getTimeDistanceCoordinates method

List<TimeDistanceCoordinate> getTimeDistanceCoordinates({ required int start, required int end, required int step, required StepType stepType, })

Build a timestamped list of coordinates sampled along the route.

Samples coordinates at regular intervals between start and end. The sampling interval is determined by step and stepType (distance or time).

Parameters

• start: Start distance from route start in meters.
• end: End distance from route start in meters.
• step: Step size (units determined by stepType).
• stepType: Unit used for step — see StepType.

Returns

• A List<TimeDistanceCoordinate> containing sampled coordinates with associated time/distance metadata.

Implementation

List<TimeDistanceCoordinate> getTimeDistanceCoordinates({
  required final int start,
  required final int end,
  required final int step,
  required final StepType stepType,
}) {
  final OperationResult resultString = objectMethod(
    pointerId,
    'RouteBase',
    'getTimeDistanceCoordinates',
    args: <String, Object>{
      'start': start,
      'end': end,
      'step': step,
      'stepType': stepType == StepType.distance,
    },
  );

  final List<dynamic> timeDistanceJson = resultString['result'];

  return timeDistanceJson
      .map((final dynamic e) => TimeDistanceCoordinate.fromJson(e))
      .toList();
}
