I want to show a data string from firebase firestore in my flutter app. This should be an info text. I want that this text gets realtime updated. My problem is with this code that i'm getting this error:

StateError (Bad state: field does not exist within the DocumentSnapshotPlatform)

I've searched trough the entire internet but i haven't found any solutions for this... i hope someone can help me. If you need more code just ask in the comments section :)
