## Usages

1. Scroller

    ```swift

    Scroller(.vertical, value: $valueV) {

        ForEach(0...5, id: \.self) { index in

            GeometryReader { proxy in

                ScrollerVContent(value: proxy.scrollerValue(.vertical))

            }

        }

    } lastContent: {

        Rectangle()

            .fill(Color.blue)

            .overlay(Text("LastView"))

            .foregroundColor(Color.white)

    }

    ```

2. Each view only needs to conform to the ScrollerContent protocol.

    ```swift

    struct ScrollerVContent: ScrollerContent {

    

        /// Bind each view's scroll-relative value. It is a value between 0 and 1.

        var value: CGFloat = 0

        

        var body: some View {

            GeometryReader { proxy in

                ScrollerInfoView(axes: .vertical, value: value, proxy: proxy)

                    .offset(y: proxy.size.height * value)

                    .padding(10)

                Rectangle().fill(Color.blue)

                    .frame(width: proxy.size.width * value, height: 5)

                    .offset(y: proxy.size.height * value)

            }

            .background(Color.orange.opacity(1.0 - value))

        }

    }

    ```

## Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler. Once you have your Swift package set up, adding Scroller as a dependency is as easy as adding it to the dependencies value of your Package.swift.

```swift

dependencies: [

    .package(url: "https://github.com/jasudev/Scroller.git", .branch("main"))

]

```
