I am building an app that asks users to leave a star review on 5 things and a comment. It then saves to Firebase. When I want to display the ratings I would like to have all the stars added up and show an average based on all ratings left, then under that have all the comments show.
I can get each document to load separately but not sure how to average them out into one. I don't like having 25 star ratings and comments.
I have attached a screen shot of the current ListView but instead of showing the star from each submissions I would like it as described above.
I hope that makes sense.
