ERROR: The operator '[]' isn't defined for the type 'Object'. Try defining the operator '[]'

Question

I have this error quite a bit in my code and I don't know how to fix it. I have read many answers, but none of them solve it?

    if (event.snapshot.value["car_details"] != null) {
            setState(() {
              carDetailsDriver = event.snapshot.value["car_details"].toString();
            });
          }
          if (event.snapshot.value["driver_name"] != null) {
            setState(() {
              driverName = event.snapshot.value["driver_name"].toString();
            });
          }
          if (event.snapshot.value["driver_phone"] != null) {
            setState(() {
              driverphone = event.snapshot.value["driver_phone"].toString();
            });
          }

          if (event.snapshot.value["driver_location"] != null) {
            double driverLat = double.parse(
                event.snapshot.value["driver_location"]["latitude"].toString());
            double driverLng = double.parse(
                event.snapshot.value["driver_location"]["longitude"].toString());
            LatLng driverCurrentLocation = LatLng(driverLat, driverLng);

By default the snapshot's data type is Object . You can explicit it to be of dynamic type by doing this,

builder: (context, AsyncSnapshot snapshot) { // setting up data type of snapshot as just AsyncSnapshot.
  ...
