### Present a Toast with Loading State and Callbacks (SwiftUI)

Source: https://github.com/sunghyun-k/swiftui-toasts/blob/main/README.md

This advanced usage example demonstrates presenting a toast that indicates a loading state. It utilizes a `task` closure for the asynchronous operation and provides `onSuccess` and `onFailure` closures to handle the outcome, displaying appropriate messages and icons.

```swift
presentToast(
  message: "Loading...",
  task: {
    // Handle loading task
    return "Success"
  },
  onSuccess: { result in
    ToastValue(icon: Image(systemName: "checkmark.circle"), message: result)
  },
  onFailure: { error in
    ToastValue(icon: Image(systemName: "xmark.circle"), message: error.localizedDescription)
  }
)
```

### Install Toast in Root View (SwiftUI)

Source: https://github.com/sunghyun-k/swiftui-toasts/blob/main/README.md

This code snippet demonstrates how to install the toast notification library in the root view of a SwiftUI application. It uses the `.installToast` modifier to set the default position of the toasts. This is a prerequisite for presenting any toasts.

```swift
import SwiftUI
import Toasts

@main
struct MyApp: App {
  var body: some Scene {
    WindowGroup {
      ContentView()
        .installToast(position: .bottom)
    }
  }
}
```

### Present a Basic Toast with Icon and Message (SwiftUI)

Source: https://github.com/sunghyun-k/swiftui-toasts/blob/main/README.md

This snippet shows how to present a simple toast notification using the `presentToast` environment variable. It includes an icon and a message. The `ToastValue` struct is used to define the content of the toast.

```swift
@Environment(\.presentToast) var presentToast

Button("Show Toast") {
  let toast = ToastValue(
    icon: Image(systemName: "bell"),
    message: "You have a new notification."
  )
  presentToast(toast)
}
```

### Present a Toast with a Button Action (SwiftUI)

Source: https://github.com/sunghyun-k/swiftui-toasts/blob/main/README.md

This snippet shows how to add an actionable button to a toast notification. The `ToastButton` struct allows defining a title, color, and an action closure that is executed when the button is tapped.

```swift
let toast = ToastValue(
  message: "Toast with action required.",
  button: ToastButton(title: "Confirm", color: .green, action: {
    // Handle button action
  })
)
```

--------------------------------

### Present a Toast with Only a Message (SwiftUI)

Source: https://github.com/sunghyun-k/swiftui-toasts/blob/main/README.md

This code illustrates how to create and present a toast notification that only contains a message, without any icon. This is useful for simple informational toasts where an icon is not necessary.

```swift
let toast = ToastValue(
  message: "Message only toast."
)
```

### Add Toast Safe Area Observer (SwiftUI)

Source: https://github.com/sunghyun-k/swiftui-toasts/blob/main/README.md

This modifier, `.addToastSafeAreaObserver()`, is used to manually manage safe area insets for toasts, particularly in complex view hierarchies like TabView. It ensures toasts are displayed correctly in relation to safe areas.

```swift
struct ContentView: View {
  var body: some View {
    TabView {
      Tab1View()
      Tab2View()
    }
  }
}

struct Tab1View: View {
  var body: some View {
    ScrollView {
      // Your content here
    }
    .addToastSafeAreaObserver()
  }
}
```
