🔧 Usage

import NavFlow
import SwiftUI

struct ContentView: View {
 @State private var navigationPath = NavigationPath()

 var body: some View {
     NavFlowNavigationBarView(
         path: $navigationPath,
         backgroundColor: .blue,
         navigationBarHeight: StandardNavigationHeight()
     ) {
        /// Custom View For Navigation Bar
         HStack {
             Text("Back").foregroundColor(.white)
             Spacer()
             Text("Home").bold().foregroundColor(.white)
             Spacer()
             Button("Edit") { /* action */ }.foregroundColor(.white)
         }
     } content: {
         VStack {
             Text("Main content here")
                 .padding()
         }
     }
 }
}

Push Navigation

import SwiftUI
import NavFlow

struct PushExampleView: View {
    var body: some View {
        NavFlowNavigationPushLink(
            color: .blue,
            navigationHeight: StandardNavigationHeight(),
            navigationBarView: {
                HStack {
                    Text("Custom Nav")
                        .bold()
                        .foregroundColor(.white)
                    Spacer()
                    Button("Action") { /* do something */ }
                        .foregroundColor(.white)
                }
            },
            destination: Text("Destination Page")
        ) {
            Text("Go to Destination")
                .padding()
                .background(Color.gray.opacity(0.2))
                .cornerRadius(8)
        }
    }
}

Sheet Navigation

NavFlowNavigationSheetLink(
    color: .purple,
    navigationBarView: {
        Text("Sheet View").foregroundColor(.white)
    },
    destination: Text("This is a sheet")
) {
    Text("Open Sheet")
        .padding()
        .background(Color.gray.opacity(0.2))
        .cornerRadius(8)
}

📏 Navigation Bar Height

NavFlow manages bar height through the NavigationBarHeight protocol.

Standard Height (status bar + nav bar, notch-aware):

let height = StandardNavigationHeight()

Custom Dynamic Height:

let customHeight = DynamicNavigationHeight(value: 100)

Hiding Navigation Bar:

If you want, you can hide navigation bar, but you can still use its features.

NavFlowNavigationBarView(
    backgroundColor: .black,
    navigationBarHeight: StandardNavigationHeight(),
    navigationBarView: { CustomBar() },
    content: { OnboardingView() }
)
.hideNavFlowNavigationBar()
