Properties

filter ↔ List<Object>?
An expression specifying conditions on source features. Only features that match the filter are displayed.
read / writeinherited
hashCode → int
The hash code for this object.
read-onlyinherited
hillshadeAccentColor ↔ int?
The shading color used to accentuate rugged terrain like sharp cliffs and gorges. Default value: "#000000".

hillshadeEmissiveStrength ↔ double?
Controls the intensity of light emitted on the source features. Default value: 0. Minimum value: 0.

hillshadeExaggeration ↔ double?
Intensity of the hillshade Default value: 0.5. Value range: 0, 1
read / write
hillshadeExaggerationExpression ↔ List<Object>?
Intensity of the hillshade Default value: 0.5. Value range: 0, 1
read / write
hillshadeHighlightColor ↔ int?
The shading color of areas that faces towards the light source. Default value: "#FFFFFF".
read / write
hillshadeHighlightColorExpression ↔ List<Object>?
The shading color of areas that faces towards the light source. Default value: "#FFFFFF".
read / write
hillshadeIlluminationAnchor ↔ HillshadeIlluminationAnchor?
Direction of light source when map is rotated. Default value: "viewport".
read / write
hillshadeIlluminationAnchorExpression ↔ List<Object>?
Direction of light source when map is rotated. Default value: "viewport".
read / write
hillshadeIlluminationDirection ↔ double?
The direction of the light source used to generate the hillshading with 0 as the top of the viewport if hillshade-illumination-anchor is set to viewport and due north if hillshade-illumination-anchor is set to map and no 3d lights enabled. If hillshade-illumination-anchor is set to map and 3d lights enabled, the direction from 3d lights is used instead. Default value: 335. Value range: 0, 359
read / write
hillshadeIlluminationDirectionExpression ↔ List<Object>?
The direction of the light source used to generate the hillshading with 0 as the top of the viewport if hillshade-illumination-anchor is set to viewport and due north if hillshade-illumination-anchor is set to map and no 3d lights enabled. If hillshade-illumination-anchor is set to map and 3d lights enabled, the direction from 3d lights is used instead. Default value: 335. Value range: 0, 359
read / write
hillshadeShadowColor ↔ int?
The shading color of areas that face away from the light source. Default value: "#000000".
read / write
hillshadeShadowColorExpression ↔ List<Object>?
The shading color of areas that face away from the light source. Default value: "#000000".
read / write
id ↔ String
The ID of the Layer.
read / writeinherited
maxZoom ↔ double?
The maximum zoom level for the layer. At zoom levels equal to or greater than the maxzoom, the layer will be hidden.
read / writeinherited
minZoom ↔ double?
The minimum zoom level for the layer. At zoom levels less than the minzoom, the layer will be hidden.
read / writeinherited
runtimeType → Type
A representation of the runtime type of the object.
read-onlyinherited
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.
read / writeinherited
sourceId ↔ String
The id of the source.
read / write
sourceLayer ↔ String?
A source layer is an individual layer of data within a vector source. A vector source can have multiple source layers.
read / write
visibility ↔ Visibility?
The visibility of the layer.
read / writeinherited
visibilityExpression ↔ List<Object>?
The visibility of the layer.
