我用JetPack Compose 搭建的项目，有用到Navigation, 有20个页面，如何统一给所有页面加上转场动画

您可以在 Navigation 中使用 Transition API 来为所有页面添加转场动画。您可以使用 Transition API 中的 TransitionSpec 定义动画的持续时间、延迟和插值器。您还可以使用 Transition API 中的 TransitionSet 定义多个动画并将它们组合在一起。以下是一个示例代码：

val transition = MaterialSharedAxis(
    // Specify the animation direction for the X axis (horizontal).
    // The animation will move the outgoing view in the opposite direction
    // from the incoming view.
    xAxis = SharedAxisX(alignment = Alignment.Start),
    // Specify the animation direction for the Y axis (vertical).
    // The animation will move the outgoing view in the opposite direction
    // from the incoming view.
    yAxis = SharedAxisY(alignment = Alignment.Top),
    // Set the animation duration to 500 milliseconds (0.5 seconds).
    durationMillis = 500
)

NavHost(
    navController = navController,
    startDestination = "home"
) {
    // Define your navigation graph here.
}

// Add the transition to the NavHost.
NavHost(navController = navController) {
    navigation(startDestination = "home") {
        composable("home") {
            HomeScreen()
        }
        composable("profile") {
            ProfileScreen()
        }
        // Add more composable functions for each screen in your app.
    }
    // Add the transition to the NavHost.
    // The transition will apply to all screens in your app.
    navigation(startDestination = "home") {
        composable("home") {
            HomeScreen()
        }
        composable("profile") {
            ProfileScreen()
        }
        // Add more composable functions for each screen in your app.
    }
    // Add the transition to the NavHost.
    // The transition will apply to all screens in your app.
    navigation(startDestination = "home") {
        composable("home") {
            HomeScreen()
        }
        composable("profile") {
            ProfileScreen()
        }
        // Add more composable functions for each screen in your app.
    }
    // Add the transition to the NavHost.
    // The transition will apply to all screens in your app.
    navigation(startDestination = "home") {
        composable("home") {
            HomeScreen()
        }
        composable("profile") {
            ProfileScreen()
        }
        // Add more composable functions for each screen in your app.
    }
    // Add the transition to the NavHost.
    // The transition will apply to all screens in your app.
    navigation(startDestination = "home") {
        composable("home") {
            HomeScreen()
        }
        composable("profile") {
            ProfileScreen()
        }
        // Add more composable functions for each screen in your app.
    }
    // Add the transition to the NavHost.
    // The transition will apply to all screens in your app.
    navigation(startDestination = "home") {
        composable("home") {
            HomeScreen()
        }
        composable("profile") {
            ProfileScreen()
        }
        // Add more composable functions for each screen in your app.
    }
    // Add the transition to the NavHost.
    // The transition will apply to all screens in your app.
    navigation(startDestination = "home") {
        composable("home") {
            HomeScreen()
        }
        composable("profile") {
            ProfileScreen()
        }
        // Add more composable functions for each screen in your app.
    }
    // Add the transition to the NavHost.
    // The transition will apply to all screens in your app.
    navigation(startDestination = "home") {
        composable("home") {
            HomeScreen()
        }
        composable("profile") {
            ProfileScreen()
        }
        // Add more composable functions for each screen in your app.
    }
    // Add the transition to the NavHost.
    // The transition will apply to all screens in your app.
    navigation(startDestination = "home") {
        composable("home") {
            HomeScreen()
        }
        composable("profile") {
            ProfileScreen()
        }
        // Add more composable functions for each screen in your app.
    }
