Properties

hashCode → int

The hash code for this object.

no setter, inherited

id ↔ String

The ID of the Layer.

getter/setter pair, inherited

lineBlur ↔ double?

Blur applied to the line, in pixels.

getter/setter pair

lineCap ↔ LineCap?

The display of line endings.

getter/setter pair

lineColor ↔ int?

The color with which the line will be drawn.

getter/setter pair

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.

getter/setter pair

lineGapWidth ↔ double?

Draws a line casing outside of a line's actual path. Value indicates the width of the inner gap.

getter/setter pair

lineGradient ↔ int?

Defines a gradient with which to color a line feature. Can only be used with GeoJSON sources that specify "lineMetrics": true.

getter/setter pair

lineJoin ↔ LineJoin?

The display of lines when joining.

getter/setter pair

lineMiterLimit ↔ double?

Used to automatically convert miter joins to bevel joins for sharp angles.

getter/setter pair

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.

getter/setter pair

lineOpacity ↔ double?

The opacity at which the line will be drawn.

getter/setter pair

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.

getter/setter pair

lineRoundLimit ↔ double?

Used to automatically convert round joins to miter joins for shallow angles.

getter/setter pair

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.

getter/setter pair

lineTranslate ↔ List<double?>?

The geometry's offset. Values are x, y where negatives indicate left and up, respectively.

getter/setter pair

lineTranslateAnchor ↔ LineTranslateAnchor?

Controls the frame of reference for line-translate.

getter/setter pair

lineTrimOffset ↔ List<double?>?

The line trim-off percentage range based on the whole line gradinet range 0.0, 1.0. The line part between trim-start, trim-end will be marked as transparent to make a route vanishing effect. If either 'trim-start' or 'trim-end' offset is out of valid range, the default range will be set.

getter/setter pair

lineWidth ↔ double?

Stroke thickness.

getter/setter pair

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

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
