i am getting data from inside Doucument in firestor
CodePudding user response：
your code isn't clear but if your questionSnapShot is a DocumentSnapshot you can retrieve the data whiteout adding .data(), so just remove .data() if that's the case.
CodePudding user response：
If I‘d have to guess, I‘d say that you have a problem with null safety.
You can check beforhand if .data() is null or just add !
questionSnapshotData = questionSnapshot.data()!["question1"];
