@shehriyarmalik try converting element.data()["price"] into a double in your file product_provider.dart, line:131

Future getHomeAchiveData() async { List newList = []; QuerySnapshot featureSnapShot = await FirebaseFirestore.instance.collection("homeachive").get(); featureSnapShot.docs.forEach( (element) { featureData = Product( image: element.data()["image"], name: element.data()["name"], price: element.data()["price"]); <------- this might be int convert to double newList.add(featureData); }, ); homeAchive = newList; notifyListeners(); }

If the above answer doesn't help you, then also this error is not related to the provider.

[thechinkysight]

[VERBOSE-2:ui_dart_state.cc(166)] Unhandled Exception: type 'int' is not a subtype of type 'double' The second line of your issue itself is very clear, it says you are trying to pass or return a int value to a function or a variable which takes or is of type double. It is not related to Provider.

[rrousselGit]

Closing as this is unrelated to provider and instead a bug in your code (apparently the getHomeAchiveData method).

If you still have a problem, consider asking your question on StackOverflow
