Properties

geometry ↔ Point

The geometry that determines the location/shape of this annotation

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

iconAnchor ↔ IconAnchor?

Part of the icon placed closest to the anchor. Default value: "center".

getter/setter pair

iconColor ↔ int?

The color of the icon. This can only be used with SDF icons. Default value: "#000000".

getter/setter pair

iconEmissiveStrength ↔ double?

Controls the intensity of light emitted on the source features. Default value: 1. Minimum value: 0.

getter/setter pair

iconHaloBlur ↔ double?

Fade out the halo towards the outside. Default value: 0. Minimum value: 0.

getter/setter pair

iconHaloColor ↔ int?

The color of the icon's halo. Icon halos can only be used with SDF icons. Default value: "rgba(0, 0, 0, 0)".

getter/setter pair

iconHaloWidth ↔ double?

Distance of halo to the icon outline. Default value: 0. Minimum value: 0.

getter/setter pair

iconImage ↔ String?

Name of image in sprite to use for drawing an image background.

getter/setter pair

iconImageCrossFade ↔ double?

Controls the transition progress between the image variants of icon-image. Zero means the first variant is used, one is the second, and in between they are blended together. Default value: 0. Value range: 0, 1

getter/setter pair

iconOcclusionOpacity ↔ double?

The opacity at which the icon will be drawn in case of being depth occluded. Absent value means full occlusion against terrain only. Default value: 0. Value range: 0, 1

getter/setter pair

iconOffset ↔ List<double?>?

Offset distance of icon from its anchor. Positive values indicate right and down, while negative values indicate left and up. Each component is multiplied by the value of icon-size to obtain the final offset in pixels. When combined with icon-rotate the offset will be as if the rotated direction was up. Default value: 0,0.

getter/setter pair

iconOpacity ↔ double?

The opacity at which the icon will be drawn. Default value: 1. Value range: 0, 1

getter/setter pair

iconRotate ↔ double?

Rotates the icon clockwise. Default value: 0.

getter/setter pair

iconSize ↔ double?

Scales the original size of the icon by the provided factor. The new pixel size of the image will be the original pixel size multiplied by icon-size. 1 is the original size; 3 triples the size of the image. Default value: 1. Minimum value: 0.

getter/setter pair

iconTextFit ↔ IconTextFit?

Scales the icon to fit around the associated text. Default value: "none".

getter/setter pair

iconTextFitPadding ↔ List<double?>?

Size of the additional area added to dimensions determined by icon-text-fit, in clockwise order: top, right, bottom, left. Default value: 0,0,0,0.

getter/setter pair

id ↔ String

The id for annotation

getter/setter pair

image ↔ Uint8List?

The bitmap image for this Annotation Will not take effect if iconImage has been set.

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

symbolSortKey ↔ double?

Sorts features in ascending order based on this value. Features with lower sort keys are drawn and placed first. When icon-allow-overlap or text-allow-overlap is false, features with a lower sort key will have priority during placement. When icon-allow-overlap or text-allow-overlap is set to true, features with a higher sort key will overlap over features with a lower sort key.

getter/setter pair

symbolZOffset ↔ double?

Specifies an uniform elevation from the ground, in meters. Default value: 0. Minimum value: 0.

getter/setter pair

textAnchor ↔ TextAnchor?

Part of the text placed closest to the anchor. Default value: "center".

getter/setter pair

textColor ↔ int?

The color with which the text will be drawn. Default value: "#000000".

getter/setter pair

textEmissiveStrength ↔ double?

Controls the intensity of light emitted on the source features. Default value: 1. Minimum value: 0.

getter/setter pair

textField ↔ String?

Value to use for a text label. If a plain string is provided, it will be treated as a formatted with default/inherited formatting options. SDF images are not supported in formatted text and will be ignored. Default value: "".

getter/setter pair

textHaloBlur ↔ double?

The halo's fadeout distance towards the outside. Default value: 0. Minimum value: 0.

getter/setter pair

textHaloColor ↔ int?

The color of the text's halo, which helps it stand out from backgrounds. Default value: "rgba(0, 0, 0, 0)".

getter/setter pair

textHaloWidth ↔ double?

Distance of halo to the font outline. Max text halo width is 1/4 of the font-size. Default value: 0. Minimum value: 0.

getter/setter pair

textJustify ↔ TextJustify?

Text justification options. Default value: "center".

getter/setter pair

textLetterSpacing ↔ double?

Text tracking amount. Default value: 0.

getter/setter pair

textLineHeight ↔ double?

Text leading value for multi-line text. Default value: 1.2.

getter/setter pair

textMaxWidth ↔ double?

The maximum line width for text wrapping. Default value: 10. Minimum value: 0.

getter/setter pair

textOcclusionOpacity ↔ double?

The opacity at which the text will be drawn in case of being depth occluded. Absent value means full occlusion against terrain only. Default value: 0. Value range: 0, 1

getter/setter pair

textOffset ↔ List<double?>?

Offset distance of text from its anchor. Positive values indicate right and down, while negative values indicate left and up. If used with text-variable-anchor, input values will be taken as absolute values. Offsets along the x- and y-axis will be applied automatically based on the anchor position. Default value: 0,0.

getter/setter pair

textOpacity ↔ double?

The opacity at which the text will be drawn. Default value: 1. Value range: 0, 1

getter/setter pair

textRadialOffset ↔ double?

Radial offset of text, in the direction of the symbol's anchor. Useful in combination with text-variable-anchor, which defaults to using the two-dimensional text-offset if present. Default value: 0.

getter/setter pair

textRotate ↔ double?

Rotates the text clockwise. Default value: 0.

getter/setter pair

textSize ↔ double?

Font size. Default value: 16. Minimum value: 0.

getter/setter pair

textTransform ↔ TextTransform?

Specifies how to capitalize text, similar to the CSS text-transform property. Default value: "none".

getter/setter pair
