Constructors

ModelViewer({Key? key, Color backgroundColor = Colors.transparent, required String src, String? alt, bool? ar, List<String>? arModes, String? arScale, bool? autoRotate, int? autoRotateDelay, bool? autoPlay, bool? cameraControls, String? iosSrc, VoidCallback? onLoadError, VoidCallback? onLoadSuccess, Widget? loadingView, String? rotationPerSecond, bool? openCache, ModelViewController? modelViewController, bool? openGesture = false, bool? openInteractionPrompt, bool? autoZoom})
const

Properties

alt → String?
Configures the model with custom text that will be used to describe the model to viewers who use a screen reader or otherwise depend on additional semantic context to understand what they are viewing.
final
ar → bool?
Enable the ability to launch AR experiences on supported devices.
final
arModes → List<String>?
A prioritized list of the types of AR experiences to enable, if available.
final
arScale → String?
Controls the scaling behavior in AR mode in Scene Viewer. Set to "fixed" to disable scaling of the model, which sets it to always be at 100% scale. Defaults to "auto" which allows the model to be resized.
final
autoPlay → bool?
If this is true and a model has animations, an animation will automatically begin to play when this attribute is set (or when the property is set to true). The default is false.
final
autoRotate → bool?
Enables the auto-rotation of the model.
final
autoRotateDelay → int?
Sets the delay before auto-rotation begins. The format of the value is a number in milliseconds. The default is 3000.
final
autoZoom → bool?
按比例缩放
final
backgroundColor → Color
The background color for the model viewer.
final
cameraControls → bool?
Enables controls via mouse/touch when in flat view.
final
hashCode → int
The hash code for this object.
no setterinherited
iosSrc → String?
The URL to a USDZ model which will be used on supported iOS 12+ devices via AR Quick Look.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
loadingView → Widget?
final
modelViewController → ModelViewController?
final
onLoadError → VoidCallback?
final
onLoadSuccess → VoidCallback?
final
openCache → bool?
final
openGesture → bool?
final
openInteractionPrompt → bool?
final
rotationPerSecond → String?
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
src → String
The URL or path to the 3D model. This parameter is required. Only glTF/GLB models are supported.
final

Methods

createElement() → StatefulElement
Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → State<ModelViewer>
Creates the mutable state for this widget at a given location in the tree.
override
debugDescribeChildren() → List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void

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}) → 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.
