Hey I recently updated my cloud_firestore dependency from version 0.12.9+4 to 2.2.1. Now I have to make some changes in my code. I already read how to migrate the code for version 2.0.0 and changed parts of the code. But I dont get how to change it in this part:

 //imbiss list from snapshot
  List<Imbiss> _imbissListFromSnapshot(QuerySnapshot snapshot) {
    return snapshot.docs.map((doc) {
      return Imbiss(
        name: doc.data["name"],
        kind: doc.data["kind"],
        location: doc.data["location"],
        rating: doc.data["rating"],
        ratingFood: doc.data["ratingFood"],
        ratingLocation: doc.data["ratingLocation"],
        ratingPLV: doc.data["ratingPLV"],
        ratingService: doc.data["ratingService"],
        date: doc.data["date"],
        user: doc.data["user"],
      );
    }).toList();
  }

The code worked perfectly fine before and now I'm getting an error for the brackets after doc.data. Android Studio tells me: The operator '[]' isn't defined for the type 'Object Function(). Do you have any clue what I have to do?

Try this:

  List<Imbiss> _imbissListFromSnapshot(AsyncSnapshot<QuerySnapshot> snapshot) {
    return snapshot.docs.map((doc) {
      Map<String, dynamic> newDoc = doc.data();
      return Imbiss(
        name: newDoc["name"],
        kind: newDoc["kind"],
        location: newDoc["location"],
        rating: newDoc["rating"],
        ratingFood: newDoc["ratingFood"],
        ratingLocation: newDoc["ratingLocation"],
        ratingPLV: newDoc["ratingPLV"],
        ratingService: newDoc["ratingService"],
        date: newDoc["date"],
        user: newDoc["user"],
      );
    }).toList();
  }
