import SwiftUI


struct FullScreenModalView: View {
  @Environment(\.presentationMode) var presentationMode
  var body: some View {
    VStack {
      Text("Hello, World!")
        .padding()
      Button("Dismiss") {
        presentationMode.wrappedValue.dismiss()
      }
    }
    .frame(maxWidth: .infinity, maxHeight: .infinity)
    .background(Color.red)
    .edgesIgnoringSafeArea(.all)
    .onTapGesture {
      presentationMode.wrappedValue.dismiss()
    }
  }
}



struct ContentView: View {
  @State private var isPresented = false
  var body: some View {
    Button("Show Full Screen Modal") {
      self.isPresented.toggle()
      // isPresented.toggle()
    }
    .fullScreenCover(isPresented: $isPresented, content: FullScreenModalView.init)
  }
}

struct ContentView_Previews: PreviewProvider {
  static var previews: some View {
    ContentView()
  }
}

@main
struct MyApp: App {
  var body: some Scene {
    WindowGroup {
      ContentView()
    }
  }
}

The provided code defines a SwiftUI view named FullScreenModalView. This view is designed to be displayed as a full-screen modal. It uses the @Environment property wrapper to access the presentationMode environment value, which allows the view to dismiss itself.

The body property of the FullScreenModalView struct contains the view's layout. It consists of a vertical stack (VStack) that includes a Text view displaying "Hello, World!" and a Button labeled "Dismiss". When the button is pressed, it triggers the dismissal of the modal by calling presentationMode.wrappedValue.dismiss().

The VStack is configured to take up the maximum available width and height using the .frame(maxWidth: .infinity, maxHeight: .infinity) modifier. The background color of the view is set to red with the .background(Color.red) modifier. The .edgesIgnoringSafeArea(.all) modifier ensures that the view extends to cover the entire screen, including areas like the status bar.

Additionally, the view includes a tap gesture recognizer with the .onTapGesture modifier. This gesture recognizer also calls presentationMode.wrappedValue.dismiss() when the view is tapped, providing an alternative way to dismiss the modal.

Overall, this code creates a full-screen modal view with a red background that can be dismissed either by tapping the "Dismiss" button or by tapping anywhere on the screen.
