BackgroundLayer class
The background color or pattern of the map.
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".
getter/setter pair
-
backgroundColorExpression
↔ List<
Object> ? -
The color with which the background will be drawn.
Default value: "#000000".
getter/setter pair
- backgroundEmissiveStrength ↔ double?
-
Controls the intensity of light emitted on the source features.
Default value: 0. Minimum value: 0.
getter/setter pair
-
backgroundEmissiveStrengthExpression
↔ List<
Object> ? -
Controls the intensity of light emitted on the source features.
Default value: 0. Minimum value: 0.
getter/setter pair
- backgroundOpacity ↔ double?
-
The opacity at which the background will be drawn.
Default value: 1. Value range:
0, 1getter/setter pair -
backgroundOpacityExpression
↔ List<
Object> ? -
The opacity at which the background will be drawn.
Default value: 1. Value range:
0, 1getter/setter pair - 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.
getter/setter pair
-
backgroundPatternExpression
↔ List<
Object> ? -
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.
getter/setter pair
-
filter
↔ List<
Object> ? -
An expression specifying conditions on source features.
Only features that match the filter are displayed.
getter/setter pairinherited
- 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
- visibility ↔ Visibility?
-
The visibility of the layer.
getter/setter pairinherited
-
visibilityExpression
↔ List<
Object> ? -
The visibility of the layer.
