I fixed it on Android, but it still hasn't been merged.

Should I wait for merger approval, any tips to fix the issue separately on my project side?

You can do it as shown below in the AppShell.xaml.cs file:

public partial class AppShell : Shell
{
    public AppShell()
    {
        InitializeComponent();
    }

    protected override void OnHandlerChanged()
    {
        base.OnHandlerChanged();

        #if ANDROID
        
        var platformView = Handler.PlatformView;
        var shellFlyoutRenderer = (ShellFlyoutRenderer)platformView;
        shellFlyoutRenderer.LayoutDirection = Android.Views.LayoutDirection.Rtl;
        
        #elif IOS || MACCATALYST
        
        FlowDirection = FlowDirection.RightToLeft;
        
        #endif
    }
}

I couldn't find any way to correct it on Windows

Sorry it took a while @mohsenbgi! I think this looks good, thank you so much for your very first .NET MAUI contribution!

I think it might be good to add maybe some (snapshot) tests for this, but lets do that as a follow up.

Congrats @mohsenbgi! Go update your social media profiles with .NET MAUI contributor extraordinaire!

Thank you so much for your efforts on this! ^{and your patience...}
