Properties

accuracyRadius ↔ double?

The accuracy, in meters, of the position source used to retrieve the position of the location indicator. Default value: 0.

getter/setter pair

accuracyRadiusBorderColor ↔ int?

The color for drawing the accuracy radius border. To adjust transparency, set the alpha component of the color accordingly. Default value: "#ffffff".

The color for drawing the accuracy radius, as a circle. To adjust transparency, set the alpha component of the color accordingly. Default value: "#ffffff".

getter/setter pair

accuracyRadiusColorExpression ↔ List<Object>?

The color for drawing the accuracy radius, as a circle. To adjust transparency, set the alpha component of the color accordingly. Default value: "#ffffff".

getter/setter pair

accuracyRadiusExpression ↔ List<Object>?

The accuracy, in meters, of the position source used to retrieve the position of the location indicator. Default value: 0.

getter/setter pair

bearingImage ↔ String?

Name of image in sprite to use as the middle of the location indicator.

getter/setter pair

bearingImageExpression ↔ List<Object>?

Name of image in sprite to use as the middle of the location indicator.

getter/setter pair

bearingImageSize ↔ double?

The size of the bearing image, as a scale factor applied to the size of the specified image. Default value: 1.

getter/setter pair

bearingImageSizeExpression ↔ List<Object>?

The size of the bearing image, as a scale factor applied to the size of the specified image. Default value: 1.

getter/setter pair

emphasisCircleColor ↔ int?

The color of the circle emphasizing the indicator. To adjust transparency, set the alpha component of the color accordingly. Default value: "#ffffff".

getter/setter pair

emphasisCircleColorExpression ↔ List<Object>?

The color of the circle emphasizing the indicator. To adjust transparency, set the alpha component of the color accordingly. Default value: "#ffffff".

getter/setter pair

emphasisCircleGlowRange ↔ List<double?>?

Specifies a glow effect range of the emphasis circle, in pixels. If 0,0 values are provided, it renders the circle as a solid color. The first value specifies the start of the glow effect where it is equal to the circle's color, the second is the end, where it's fully transparent. Between the two values the effect is linearly faded out. Default value: 0,0.

getter/setter pair

emphasisCircleGlowRangeExpression ↔ List<Object>?

Specifies a glow effect range of the emphasis circle, in pixels. If 0,0 values are provided, it renders the circle as a solid color. The first value specifies the start of the glow effect where it is equal to the circle's color, the second is the end, where it's fully transparent. Between the two values the effect is linearly faded out. Default value: 0,0.

getter/setter pair

emphasisCircleRadius ↔ double?

The radius, in pixel, of the circle emphasizing the indicator, drawn between the accuracy radius and the indicator shadow. Default value: 0.

getter/setter pair

emphasisCircleRadiusExpression ↔ List<Object>?

The radius, in pixel, of the circle emphasizing the indicator, drawn between the accuracy radius and the indicator shadow. Default value: 0.

getter/setter pair

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

id ↔ String

The ID of the Layer.

getter/setter pair, inherited

imagePitchDisplacement ↔ double?

The displacement off the center of the top image and the shadow image when the pitch of the map is greater than 0. This helps producing a three-dimensional appearence. Default value: "0".

getter/setter pair

imagePitchDisplacementExpression ↔ List<Object>?

The displacement off the center of the top image and the shadow image when the pitch of the map is greater than 0. This helps producing a three-dimensional appearence. Default value: "0".

getter/setter pair

locationIndicatorOpacityExpression ↔ List<Object>?

The opacity of the entire location indicator layer. Default value: 1. Value range: 0, 1

getter/setter pair

maxZoom ↔ double?

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

perspectiveCompensation ↔ double?

The amount of the perspective compensation, between 0 and 1. A value of 1 produces a location indicator of constant width across the screen. A value of 0 makes it scale naturally according to the viewing projection. Default value: "0.85".

getter/setter pair

perspectiveCompensationExpression ↔ List<Object>?

The amount of the perspective compensation, between 0 and 1. A value of 1 produces a location indicator of constant width across the screen. A value of 0 makes it scale naturally according to the viewing projection. Default value: "0.85".

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited
