Properties
- annotationHeight → double
-
final
-
annotations
→ List<
ArAnnotation> -
final
- annotationViewBuilder → AnnotationViewBuilder
-
final
- annotationWidth → double
-
final
- backgroundRadar → Color?
-
background radar color
final
- cameraFieldOfView → double?
-
Field of view of the back camera along its long side, in degrees. When
null, it is read from the device, falling back to
AnnotationLayoutConfig.defaultCameraFieldOfView.
final
- frame → Size
-
final
- groupBadgeBuilder → AnnotationGroupBadgeBuilder?
-
Badge shown on a label that has annotations grouped into it. Defaults
to a "+N" bubble on its top-right corner; return
const SizedBox.shrink()to hide it.final - hashCode → int
-
The hash code for this object.
no setterinherited
- hideWithinLocationAccuracy → bool
-
Hide POIs closer than the location accuracy, see
AnnotationLayoutConfig.hideWithinLocationAccuracy.
final
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- markerColor → Color?
-
Radar
marker color in radar
final
- maxRows → int?
-
Maximum number of stacked rows of labels, see
AnnotationLayoutConfig.maxRows.
final
- maxVisibleDistance → double
-
final
- minDistanceReload → double
-
final
- minScale → double
-
Scale of a label at maxVisibleDistance when scaleWithDistance: labels
shrink linearly from 1 next to the user down to this value.
final
- onLocationChange → ChangeLocationCallback
-
final
- paddingOverlap → double
-
final
- previewAspectRatio → double?
-
Aspect ratio (long side / short side) of the camera preview shown behind
this view. Defaults to AnnotationLayoutConfig.defaultPreviewAspectRatio.
final
- radarPosition → RadarPosition?
-
radar position in view
final
- radarWidth → double?
-
Radar width
final
- rowAnimationDuration → Duration
-
Duration of the transition when a label moves to another overlap row.
Duration.zero disables the animation.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- scaleWithDistance → bool
-
Scale annotation view with distance from user
final
- sensorErrorBuilder → ArSensorErrorBuilder?
-
Widget shown when the sensor source reports an error (e.g. location
permission denied) before any location is known. Defaults to a short
message.
final
- sensorSource → ArSensorSource?
-
Source of fused sensor/location samples. Defaults to a device-backed
ArSensorManager instantiated per ArView. Provide your own
implementation (e.g. a fake source) to test without real hardware or
to share a single sensor pipeline across multiple views. A provided
source is not disposed by ArView: its owner must dispose it.
final
- showDebugInfoSensor → bool
-
final
- showRadar → bool
-
Show radar in view
final
- useAltitude → bool
-
Place POIs above/below the horizon from their altitude, see
AnnotationLayoutConfig.useAltitude.
final
- yOffsetOverlap → double?
-
final
Methods
-
createElement(
) → StatefulElement -
Creates a StatefulElement to manage this widget's location in the tree.
inherited
-
createState(
) → State< ArView> -
Creates the mutable state for this widget at a given location in the tree.
override

children.
inherited

Invoked when a nonexistent method or property is accessed.
inherited
-
toDiagnosticsNode(
{String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode -
Returns a debug representation of the object that is used by debugging
tools and by DiagnosticsNode.toStringDeep.
inherited
-
toString(
{DiagnosticLevel minLevel = DiagnosticLevel.info}) → String -
A string representation of this object.
inherited
-
toStringDeep(
{String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String -
Returns a string representation of this node and its descendants.
inherited
-
toStringShallow(
{String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String -
Returns a one-line detailed description of the object.
inherited
-
toStringShort(
) → String -
A short, textual description of this widget.
