Using ScrollViewReactiveHeader is easy:

ScrollViewReactiveHeader(header: {

    MyHeaderBackground()
        .frame(height: 300)
}, headerOverlay: {

    MyHeaderContent()
        .frame(height: 300)
}, body: {

    // Note: This view will be placed inside a ScrollView
    MyScrollingContentView()
}, configuration: .init(showStatusBar: true, backgroundColor: .white))

Future Todos

• [ ] Make headerOverlay interactive. At the moment, taps will be blocked by the overlaid ScrollView
• [ ] Add optional callback that reports internally-calculated scroll offset.
• [ ] Remove dependency on GeometryReader for calculating status bar height. (at the moment, setting .edgesIgnoringSafeArea(.top) will interfere with this package's ability to calculate the height of the status bar. )
