How to make a rating system like that of Kinopoisk in flutter?

Hello everyone I am developing an application in which the user will evaluate the book he has read, for this I want to implement a similar rating system as the streaming service Kinopoisk! The selected score must be saved to a variable. I use flutter, thanks in advance for the help.
