Methods
-
addRoute(
{required LatLng start, required LatLng destination, required List< LatLng> waypoints, required bool optimize, required String profile, required String language, bool fitCamera = true}) → Future<PowerMapRouteResult?> -
Calculates and draws a route between
startanddestination. -
addRouteWithAlternatives(
{required LatLng start, required LatLng destination, String profile = 'driving', String language = 'th', int maxAlternatives = 3, bool fitCamera = true}) → Future< PowerMapRoutesResult?> -
Calculates multiple routes between
startanddestinationusing the Alternative Route API. -
clearAlternativeRoutes(
) → Future< void> - Clears only the alternative route lines (used when starting navigation).
-
clearRoutes(
) → Future< void> -
clearStepTurnArrows(
) → Future< void> - Clears step turn arrow data (sets empty GeoJSON). Layers stay alive for instant reuse.
-
disposeStepTurnArrows(
) → Future< void> - Fully removes step arrow layers and source. Call on route dismissal/disposal only.
-
drawRoutes(
List< PowerMapRouteResult> routes, {int selectedIndex = 0, bool fitCamera = true}) → Future<void> - Renders multiple routes on the map.
-
drawSavedRoute(
List< LatLng> geometry) → void - Redraws an existing geometry without calling the API again. Used for restoring the original path after stopping navigation.
-
drawStepTurnArrows(
{required List< PowerRouteStep> steps, required List<LatLng> routeGeometry, int? selectedStepIndex, int? currentStepIndex, int maxUpcomingCount = 3, double? distanceTraveled, double? zoom, String? belowLayerId}) → Future<void> - Renders compact white sub-polyline turn arrows focused tightly at turn corners (Google Maps Style). Mutex-serialized: if called while a previous draw is in progress, waits for it to finish first.
-
findNearestRouteIndex(
LatLng tapLocation, {double maxDistanceMeters = 35.0, double? zoom, double touchRadiusPixels = 56.0}) → int -
Finds the route index whose polyline is closest to
tapLocation. -
getRouteDivergentPoint(
int routeIndex) → LatLng -
Calculates the point along _currentRoutes
routeIndexthat has the greatest separation from all other routes, ideal for placing on-map floating tooltips (Google Maps style). -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
selectRoute(
int index, {bool animateCamera = false}) → Future< void> -
Changes the active/selected route to
indexand redraws the layers accordingly. -
toString(
) → String -
A string representation of this object.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
