Flutter : read data from firebase using Getx

I am trying to display the data on the page But this error appears to me Is there a solution to this?

controller

RxInt pprofit = 0.obs ; 

void onInit() async{
      super.onInit();
    // TODO: implement onInit

      CollectionReference fprofits = FirebaseFirestore.instance.collection('admin');
      await fprofits.doc('profits').get().then((value) {
        pprofit = value.data()['profits'];
      }); }

iam trying to get this value only enter image description here

error

    Error: The operator '[]' isn't defined for the class 'Object?'.
 - 'Object' is from 'dart:core'.
Try correcting the operator to an existing operator, or defining a '[]' operator.
        pprofit = value.data()['profits'];

Maybe this can hel you

CollectionReference fprofits = FirebaseFirestore.instance;

final collection = await fprofits.collection('admin').doc('profits').get();
final data = collection.data();
print(data);

you can transform it in Map

CollectionReference fprofits = FirebaseFirestore.instance;

final collection = await fprofits.collection('admin').doc('profits').get();
Map<String, dynamic> data = collection.data() as Map<String, dynamic>;
print(data);

tell if worked for you
