Flutter Blank page when Open the App from facebook ads link with deep linking

Question

we have a flutter application, and we are doing a Facebook ads campaign to get conversion inside the app., and for that, we use deep-linking.

but the problem is that when the users that already installed the app, click on the Facebook ads link. they go to a blank page inside the app.

this is the app manifast , this is the AndroidManifast code :
