Methods

activate() → void
Called when this object is reinserted into the tree after having been removed via deactivate.
inherited
addMargins(Widget view) → Widget
applies margins to the view based on the widget model
inherited
applyConstraints(Widget view, Constraints constraints) → Widget
This routine applies the given constraints to the supplied view and then returns a widget with the view wrapped in those constraints
inherited
applyTransforms(Widget view) → Widget
applies transforms like rotate, flip, etc.
inherited
build(BuildContext context) → Widget
Describes the part of the user interface represented by this widget.
override
calculateSize(Map<String, int> srcSize, Map<String, int> dstSize) → Map<String, dynamic>
deactivate() → void
Called when this object is removed from the tree.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
inherited
didChangeDependencies() → void
Called when a dependency of this State object changes.
inherited
didUpdateWidget(covariant dynamic oldWidget) → void
Called whenever the widget configuration changes.
inherited
dispose() → void
Called when this object is removed from the tree permanently.
override
initState() → void
Called when this object is inserted into the tree.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onError(dynamic error) → dynamic
onLayout(BoxConstraints constraints) → void
inherited
onModelChange(Model model, {String? property, dynamic value}) → dynamic
Callback to fire the _ViewState.build when the CameraModel changes
override
onSnapshot(List<int> bytes, int width, int height, UriData uri) → Future<void>
onStream(List<int> bytes, int width, int height) → void
pause() → Future
performDetection() → void
play() → Future
reassemble() → void
Called whenever the application is reassembled during debugging, for example during hot reload.
inherited
renderFrame(num epoch) → void
setState(VoidCallback fn) → void
Notify the framework that the internal state of this object has changed.
inherited
snapshot() → Future
start() → Future
stop() → Future
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toggleCamera() → dynamic
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String
A string representation of this object.
inherited
toStringShort() → String
A brief description of this object, usually just the runtimeType and the hashCode.
