                      ARAnnotationsView

Content View which displays the card and marker views after a discovery flow for a single Image in the scene after the discoveryFlowHasFinished has been set to True. Only displays the views which are set to isVisible. Cards and Markers are initially set to isVisible.

Usage

// Constructor for Default ScanningView, CardView, and MarkerView
ARAnnotationsView(arModel: arModel,
                      image: Image("qrImage"),
                      cardAction: { id in
                            // set the card action for id corresponding to the CardItemModel
                            print(id)
                      })
        .onAppear(perform: loadData)

// Constructors with viewbuilders for each combination of Views
// Use the CarouselOptions View Modifier to adjust the behavior of the Carousel
ARAnnotationsView(arModel: arModel,
                      scanLabel: { anchorPosition in
                          CustomScanView(image: Image("qrImage"), position: anchorPosition)
                      },
                      cardLabel: { cardmodel, isSelected in
                          CustomCardView(networkModel: cardmodel, isSelected: isSelected)
                      },
                      markerLabel: { state, icon  in
                          CustomMarkerView(state: state)
                      })
        .carouselOptions(CarouselOptions(itemSpacing: 5, carouselHeight: 200, alignment: .center))
        .onAppear(perform: loadData)

func loadData() {
    let cardItems = Tests.cardItems
    guard let anchorImage = UIImage(named: "qrImage") else { return }
    let strategy = RealityComposerStrategy(cardContents: cardItems, anchorImage: anchorImage, rcFile: "ExampleRC", rcScene: "ExampleScene")
    arModel.load(loadingStrategy: strategy)
}
