LocationIndicator class abstract

Graphical object to represent the location of the user on the map.

It is either a green dot for pedestrian style or a triangular arrow for vehicle navigation style. This style can be changed by LocationIndicator.locationIndicatorStyle

The location is made available to an instance of this class by calling LocationIndicator.updateLocation or LocationIndicator.updateLocationAndCamera.

Use LocationIndicator.enable to add this object to the map and LocationIndicator.disable to remove it.

Note: The LocationIndicator is always rendered at a fixed altitude near 0. Changing the MapCamera to look at geographic coordinates with an altitude that is higher can cause the following behavior: If the MapCamera angle is tilted and altitude is too high, the LocationIndicator can unexpectedly disappear from the viewport due to the new perspective.

Constructors

Properties

hashCode → int
The hash code for this object.
no setterinherited
isAccuracyVisualized ↔ bool
Whether the horizontal accuracy is visualized by scaling the accuracy indicator halo. Returns whether Location.horizontalAccuracyInMeters is used to scale the accuracy indicator halo. Default is false, in which case the halo has a fixed and zoom level independent size.
getter/setter pair
isActive ↔ bool
A Boolean value that determines whether the active on inactive version of location indicator is shown. Returns true if active version of the location indicator is shown or false when inactive version is shown. By default, it is true.
getter/setter pair
locationIndicatorStyle ↔ LocationIndicatorIndicatorStyle
The visual style of location indicator. By default, it is set to LocationIndicatorIndicatorStyle.navigation. Returns visual style of location indicator.
getter/setter pair
materialReflectivity ↔ MaterialReflectivity?
The material reflectivity properties of the location indicator. Enables per‑pixel lighting for all internal markers (navigation, pedestrian, inactive variants) and the halo when assigned. While materialReflectivity is non‑null the markers are shaded by scene lights using the provided ambient / diffuse factors. When set back to null, lighting is disabled and markers revert to unlit (emissive) rendering.
getter/setter pair
opacity ↔ double
The factor applied to the alpha channel of both the location indicator's texture and the accuracy indicator's halo color. Default value is 1.0 which means location indicator is displayed with the default alpha channel of the texture. Gets the current opacity of the location indicator.
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
