Add App link for sharing before submitting on app store


I am adding share button on my app, which shares my app link on FB whatsapp.
But how do i get app store link to add in my app, before submitting the same to Play store

You Play store link will be based on the package name you gave your app.

My Widget Id and package name is as below
<widget id=“” version=“0.0.1”
“name”: “hair”,

That would make the link

This is all documented at by the way.

Thanks a lot, for a quick help.
