Properties

filter ↔ List<Object>?

An expression specifying conditions on source features. Only features that match the filter are displayed.

getter/setter pair, inherited

hashCode → int

The hash code for this object.

no setter, inherited

hillshadeAccentColor ↔ int?

The shading color used to accentuate rugged terrain like sharp cliffs and gorges. Default value: "#000000".

getter/setter pair

hillshadeAccentColorExpression ↔ List<Object>?

The shading color used to accentuate rugged terrain like sharp cliffs and gorges. Default value: "#000000".

getter/setter pair

hillshadeEmissiveStrength ↔ double?

Controls the intensity of light emitted on the source features. Default value: 0. Minimum value: 0.

getter/setter pair

hillshadeEmissiveStrengthExpression ↔ List<Object>?

Controls the intensity of light emitted on the source features. Default value: 0. Minimum value: 0.

getter/setter pair

hillshadeExaggeration ↔ double?

Intensity of the hillshade Default value: 0.5. Value range: 0, 1

getter/setter pair

hillshadeExaggerationExpression ↔ List<Object>?

Intensity of the hillshade Default value: 0.5. Value range: 0, 1

getter/setter pair

hillshadeHighlightColor ↔ int?

The shading color of areas that faces towards the light source. Default value: "#FFFFFF".

getter/setter pair

hillshadeHighlightColorExpression ↔ List<Object>?

The shading color of areas that faces towards the light source. Default value: "#FFFFFF".

getter/setter pair

hillshadeIlluminationAnchor ↔ HillshadeIlluminationAnchor?

Direction of light source when map is rotated. Default value: "viewport".

getter/setter pair

hillshadeIlluminationAnchorExpression ↔ List<Object>?

Direction of light source when map is rotated. Default value: "viewport".

getter/setter pair

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

getter/setter pair

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

getter/setter pair

hillshadeShadowColor ↔ int?

The shading color of areas that face away from the light source. Default value: "#000000".

getter/setter pair

hillshadeShadowColorExpression ↔ List<Object>?

The shading color of areas that face away from the light source. Default value: "#000000".

getter/setter pair

id ↔ String

The ID of the Layer.

getter/setter pair, inherited

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 pair, inherited

minZoom ↔ double?

The minimum zoom level for the layer. At zoom levels less than the minzoom, the layer will be hidden.

getter/setter pair, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

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 pair, inherited

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.

getter/setter pair, inherited

visibilityExpression ↔ List<Object>?

The visibility of the layer.
