如何在使用xamarin shell时更改状态栏颜色

using Xamarin.Forms;
using Xamarin.Essentials;

public partial class App : Application
{
    public App()
    {
        InitializeComponent();

        // 设置状态栏颜色
        SetStatusBarColor(Color.Red); // 替换为你想要的颜色

        MainPage = new AppShell();
    }

    protected override void OnStart()
    {
    }

    protected override void OnSleep()
    {
    }

    protected override void OnResume()
    {
    }

    // 设置状态栏颜色的方法
    private void SetStatusBarColor(Color color)
    {
        Device.BeginInvokeOnMainThread(() =>
        {
            var androidColor = color.ToPlatformColor();
            var window = Xamarin.Essentials.Platform.CurrentActivity.Window;
            window.SetStatusBarColor(androidColor);
        });
    }
}
