Properties

fillExtrusionAmbientOcclusionGroundAttenuation ↔ double?
Provides a control to futher fine-tune the look of the ambient occlusion on the ground beneath the extruded buildings. Lower values give the effect a more solid look while higher values make it smoother.
getter/setter pair
fillExtrusionAmbientOcclusionGroundRadius ↔ double?
The extent of the ambient occlusion effect on the ground beneath the extruded buildings in meters.
getter/setter pair
fillExtrusionAmbientOcclusionIntensity ↔ double?
Controls the intensity of shading near ground and concave angles between walls. Default value 0.0 disables ambient occlusion and values around 0.3 provide the most plausible results for buildings.
getter/setter pair
fillExtrusionAmbientOcclusionRadius ↔ double?
Shades area near ground and concave angles between walls where the radius defines only vertical impact. Default value 3.0 corresponds to height of one floor and brings the most plausible results for buildings. This property works only with legacy light. When 3D lights are enabled fill-extrusion-ambient-occlusion-wall-radius and fill-extrusion-ambient-occlusion-ground-radius are used instead.
getter/setter pair
fillExtrusionAmbientOcclusionWallRadius ↔ double?
Shades area near ground and concave angles between walls where the radius defines only vertical impact. Default value 3.0 corresponds to height of one floor and brings the most plausible results for buildings.
getter/setter pair
fillExtrusionBase ↔ double?
The height with which to extrude the base of this layer. Must be less than or equal to fill-extrusion-height.
getter/setter pair
fillExtrusionColor ↔ int?
The base color of the extruded fill. The extrusion's surfaces will be shaded differently based on this color in combination with the root light settings. If this color is specified as rgba with an alpha component, the alpha component will be ignored; use fill-extrusion-opacity to set layer opacity.
getter/setter pair
fillExtrusionCutoffFadeRange ↔ double?
This parameter defines the range for the fade-out effect before an automatic content cutoff on pitched map views. The automatic cutoff range is calculated according to the minimum required zoom level of the source and layer. The fade range is expressed in relation to the height of the map view. A value of 1.0 indicates that the content is faded to the same extent as the map's height in pixels, while a value close to zero represents a sharp cutoff. When the value is set to 0.0, the cutoff is completely disabled. Note: The property has no effect on the map if terrain is enabled.
getter/setter pair
fillExtrusionEdgeRadius ↔ double?
Radius of a fill extrusion edge in meters. If not zero, rounds extrusion edges for a smoother appearance.
getter/setter pair
fillExtrusionEmissiveStrength ↔ double?
Controls the intensity of light emitted on the source features.
getter/setter pair
fillExtrusionFloodLightColor ↔ int?
The color of the flood light effect on the walls of the extruded buildings.
getter/setter pair
fillExtrusionFloodLightGroundAttenuation ↔ double?
Provides a control to futher fine-tune the look of the flood light on the ground beneath the extruded buildings. Lower values give the effect a more solid look while higher values make it smoother.
getter/setter pair
fillExtrusionFloodLightGroundRadius ↔ double?
The extent of the flood light effect on the ground beneath the extruded buildings in meters.
getter/setter pair
fillExtrusionFloodLightIntensity ↔ double?
The intensity of the flood light color.
getter/setter pair
fillExtrusionFloodLightWallRadius ↔ double?
The extent of the flood light effect on the walls of the extruded buildings in meters.
getter/setter pair
fillExtrusionHeight ↔ double?
The height with which to extrude this layer.
getter/setter pair
fillExtrusionOpacity ↔ double?
The opacity of the entire fill extrusion layer. This is rendered on a per-layer, not per-feature, basis, and data-driven styling is not available.
getter/setter pair
fillExtrusionPattern ↔ String?
Name of image in sprite to use for drawing images on extruded fills. For seamless patterns, image width and height must be a factor of two (2, 4, 8, ..., 512). Note that zoom-dependent expressions will be evaluated only at integer zoom levels.
getter/setter pair
fillExtrusionRoundedRoof ↔ bool?
Indicates whether top edges should be rounded when fill-extrusion-edge-radius has a value greater than 0. If false, rounded edges are only applied to the sides. Default is true.
getter/setter pair
fillExtrusionTranslate ↔ List<double?>?
The geometry's offset. Values are x, y where negatives indicate left and up (on the flat plane), respectively.
getter/setter pair
fillExtrusionTranslateAnchor ↔ FillExtrusionTranslateAnchor?
Controls the frame of reference for fill-extrusion-translate.
getter/setter pair
fillExtrusionVerticalGradient ↔ bool?
Whether to apply a vertical gradient to the sides of a fill-extrusion layer. If true, sides will be shaded slightly darker farther down.
getter/setter pair
fillExtrusionVerticalScale ↔ double?
A global multiplier that can be used to scale base, height, AO, and flood light of the fill extrusions.
getter/setter pair
hashCode → int
The hash code for this object.
no setterinherited
id ↔ String
The ID of the Layer.
getter/setter pairinherited
maxZoom ↔ double?
The maximum zoom level for the layer. At zoom levels equal to or greater than the maxzoom, the layer will be hidden.
getter/setter pairinherited
minZoom ↔ double?
The minimum zoom level for the layer. At zoom levels less than the minzoom, the layer will be hidden.
getter/setter pairinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
slot ↔ String?
The slot this layer is assigned to. If specified, and a slot with that name exists, it will be placed at that position in the layer order.
getter/setter pairinherited
sourceId ↔ String
The id of the source.
getter/setter pair
sourceLayer ↔ String?
A source layer is an individual layer of data within a vector source. A vector source can have multiple source layers.
getter/setter pair
visibility ↔ Visibility?
The visibility of the layer.
