SolidScrollView-example.swift

struct ContentView: View {
  var config = ScrollViewConfig()
  @State var scrollViewProxy: SolidScrollViewProxy?

  var body: some View {
    VStack(spacing: 0) {
      SolidScrollView(config) {
        VStack(spacing: 0) {
          Color.red.frame(height: 200)
          Color.green.frame(height: 200)
          Color.blue.frame(height: 200)
          Color.black.frame(height: 200)
        }
      }
      Button("Scroll to 3/4 of the content height via proxy") {
        guard let scrollViewProxy = scrollViewProxy else { return }
        let contentOffset = CGPoint(x: 0, y: min(scrollViewProxy.contentSize.height * 3.0 / 4, scrollViewProxy.maxContentOffset.y))
        scrollViewProxy.setContentOffset(contentOffset, animated: true, completion: { completed in
          print("Scrolled via proxy to \(contentOffset)! Completed: \(completed)")
        })
      }
    }
    .onPreferenceChange(ContainedScrollViewKey.self) {
      scrollViewProxy = $0
    }
