[Flutter] Reviews are fetch to all users instead to the only one receiving them

I am creating a flutter app for booking services but I have a problem with retrieving the reviews , when a user is adding a review it shows that review to all users profiles instead to only him( I don't know if the problems starts from the way Add review functionality is or from displaying and fetching them or both). Im gonna let a video explaining here the issue https://imgur.com/a/Kd0ZMSo

milliseconds: 400,
