Properties

hashCode → int
The hash code for this object.
read-onlyinherited
id ↔ String
The ID of the Layer.
read / writeinherited
lineBlur ↔ double?
Blur applied to the line, in pixels.
read / write
lineBorderColor ↔ int?
The color of the line border. If line-border-width is greater than zero and the alpha value of this color is 0 (default), the color for the border will be selected automatically based on the line color.
read / write
lineBorderWidth ↔ double?
The width of the line border. A value of zero means no border.
read / write
lineCap ↔ LineCap?
The display of line endings.
read / write
lineColor ↔ int?
The color with which the line will be drawn.
read / write
lineDasharray ↔ List<double?>?
Specifies the lengths of the alternating dashes and gaps that form the dash pattern. The lengths are later scaled by the line width. To convert a dash length to pixels, multiply the length by the current line width. Note that GeoJSON sources with lineMetrics: true specified won't render dashed lines to the expected scale. Also note that zoom-dependent expressions will be evaluated only at integer zoom levels.
read / write
lineDepthOcclusionFactor ↔ double?
Decrease line layer opacity based on occlusion from 3D objects. Value 0 disables occlusion, value 1 means fully occluded.
read / write
lineEmissiveStrength ↔ double?
Controls the intensity of light emitted on the source features.
read / write
lineGapWidth ↔ double?
Draws a line casing outside of a line's actual path. Value indicates the width of the inner gap.
read / write
lineGradient ↔ int?
A gradient used to color a line feature at various distances along its length. Defined using a step or interpolate expression which outputs a color for each corresponding line-progress input value. line-progress is a percentage of the line feature's total length as measured on the webmercator projected coordinate plane (a number between 0 and 1). Can only be used with GeoJSON sources that specify "lineMetrics": true.
read / write
lineJoin ↔ LineJoin?
The display of lines when joining.
read / write
lineMiterLimit ↔ double?
Used to automatically convert miter joins to bevel joins for sharp angles.
read / write
lineOffset ↔ double?
The line's offset. For linear features, a positive value offsets the line to the right, relative to the direction of the line, and a negative value to the left. For polygon features, a positive value results in an inset, and a negative value results in an outset.
read / write
lineOpacity ↔ double?
The opacity at which the line will be drawn.
read / write
linePattern ↔ String?
Name of image in sprite to use for drawing image lines. For seamless patterns, image width must be a factor of two (2, 4, 8, ..., 512). Note that zoom-dependent expressions will be evaluated only at integer zoom levels.
read / write
lineRoundLimit ↔ double?
Used to automatically convert round joins to miter joins for shallow angles.
read / write
lineSortKey ↔ double?
Sorts features in ascending order based on this value. Features with a higher sort key will appear above features with a lower sort key.
read / write
lineTranslate ↔ List<double?>?
The geometry's offset. Values are x, y where negatives indicate left and up, respectively.
read / write
lineTranslateAnchor ↔ LineTranslateAnchor?
Controls the frame of reference for line-translate.
read / write
lineTrimOffset ↔ List<double?>?
The line part between trim-start, trim-end will be marked as transparent to make a route vanishing effect. The line trim-off offset is based on the whole line range 0.0, 1.0.
read / write
lineWidth ↔ double?
Stroke thickness.
read / write
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
