Firestore connection to Flutter app

I have a Firestore database connected to my Flutter app. The problem is, the database is only PARTIALLY connecting to my app. Data that I've entered manually connects perfectly, and is visible in the app. But data that is entered through a Google sheet app script does not appear in the app. The data is definitely there in the database - I can SEE it - but it's not connecting to my app.

I'm looking for someone to connect the data that I can see in the database to my app.
