Constructors

BackgroundLayer({required String id, Visibility? visibility, List<Object>? visibilityExpression, List<Object>? filter, double? minZoom, double? maxZoom, String? slot, int? backgroundColor, List<Object>? backgroundColorExpression, double? backgroundEmissiveStrength, List<Object>? backgroundEmissiveStrengthExpression, double? backgroundOpacity, List<Object>? backgroundOpacityExpression, String? backgroundPattern, List<Object>? backgroundPatternExpression})

Properties

backgroundColor ↔ int?
The color with which the background will be drawn. Default value: "#000000".
read / write
backgroundColorExpression ↔ List<Object>?
The color with which the background will be drawn. Default value: "#000000".
read / write
backgroundEmissiveStrength ↔ double?
Controls the intensity of light emitted on the source features. Default value: 0. Minimum value: 0.
read / write
backgroundEmissiveStrengthExpression ↔ List<Object>?
Controls the intensity of light emitted on the source features. Default value: 0. Minimum value: 0.
read / write
backgroundOpacity ↔ double?
The opacity at which the background will be drawn. Default value: 1. Value range: 0, 1
read / write
backgroundOpacityExpression ↔ List<Object>?
The opacity at which the background will be drawn. Default value: 1. Value range: 0, 1
read / write
backgroundPattern ↔ String?
Name of image in sprite to use for drawing an image background. 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.

backgroundPatternExpression ↔ List<Object>?

read / write
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
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
visibility ↔ Visibility?
The visibility of the layer.
read / writeinherited
visibilityExpression ↔ List<Object>?
The visibility of the layer.
