How to retrieve the TotalClassesTook field value from this doc Error image

Solution

While using the FirebaseFirestore.instance to get your data, the .get() is for specifying the GetOptions with feature like cache.

But that is not what you require.

Use it like this,

totalClasses = await FirebaseFirestore.instance
    .collection('tutors')
    .doc(uid)
    .get()
    .then((value) {
       return value.data()['TotalClassesTook']; // Access your after your get the data
     });
