getter/setter pairinherited
- hashCode → int
-
The hash code for this object.
no setterinherited
- id ↔ String
-
The ID of the Layer.
getter/setter pairinherited
- imagePitchDisplacement ↔ double?

An array of
latitude, longitude, altitudeposition of the location indicator. Default value:0,0,0.getter/setter pair -
locationExpression
↔ List<
Object> ? -
An array of
latitude, longitude, altitudeposition of the location indicator. Default value:0,0,0.getter/setter pair - locationIndicatorOpacity ↔ double?
