TrafficMergeWarningListener constructor
- void onTrafficMergeWarningUpdatedLambda()
This abstract class should be implemented in order to receive traffic merge warnings.
Note: The traffic merge warner is a point warner, which means that for a traffic merge there will always be
2 warnings emitted, with the TrafficMergeWarning.distance_type set to DistanceType.AHEAD and DistanceType.PASSED
which is given when the location of the traffic merge is reached.
A TrafficMergeWarning will not be given until the previous warning of that type has been passed.
For example, a route with TrafficMergeWarning 120 meters and TrafficMergeWarning 160 meters ahead,
the first TrafficMergeWarning.distance_to_traffic_merge_in_meters is 120 meters
and the next TrafficMergeWarning.distance_to_traffic_merge_in_meters is then 40 meters,
since that is the distance between the first and second warnings.
Implementation
factory TrafficMergeWarningListener(
void Function(TrafficMergeWarning) onTrafficMergeWarningUpdatedLambda,
) => TrafficMergeWarningListener$Lambdas(
onTrafficMergeWarningUpdatedLambda,
);
