🐛 [firebase_analytics] cannot set default parameter due to invalid type

[kkoken]

Bug report

Describe the bug
Cannot set Default parameter to firebase analytics using firebaseAnalytics.setDefaultEventParameters.
It gives me an error of invalid default event parameter type and only happens in Android.

W/FA      (24001): Invalid default event parameter type. Name, value: isFree, true
W/FA      (24001): Invalid default event parameter type. Name, value: optIn, true
W/FA      (24001): Invalid default event parameter type. Name, value: isGranted, true

Steps to reproduce

Test device -> Xiaomi Mi 9T(or K20) (Android 11)

// Defined top of the main func
final FirebaseAnalytics firebaseAnalytics = FirebaseAnalytics.instance;
void main() {
// code
}

// Method runs after after splash
Future<void> initializeAnalytics() async {
 await firebaseAnalytics.setUserId(id: model.id);

 final Map<String, Object?> superProperties = <String, Object?>{};

 final isAllowed = await NotificationService.instance.notificationPermissionStatus;

 superProperties.putIfAbsent('isFree', () => model.free);
 superProperties.putIfAbsent('optIn', () => isAllowed);
 superProperties.putIfAbsent('isGranted', () => model.isGranted);

 await firebaseAnalytics.setDefaultEventParameters(superProperties);
}

Expected behavior

To be able to set the default parameters to all events.

[darshankawar]

Thanks for the report @kkoken
Can you provide a complete minimal reproducible code sample that shows the current behavior ?

[kkoken]

@darshankawar Should I include google-services.json under android/app/src or will you guys add to project?

[kkoken]

@darshankawar without google-services.json example

[darshankawar]

Thanks for the details. Using it, I am getting same behavior on Android as reported.

/cc @russellwheatley

[kkoken]

@darshankawar @russellwheatley It appears to be analytics.setDefaultEventParameters (line 309) on FlutterFirebaseAnalyticsPlugin.java file does not accept boolean values.

---

Method Explanation:

public void setDefaultEventParameters (Bundle parameters)

Adds parameters that will be set on every event logged from the SDK, including automatic ones. The values passed in the parameters bundle will be added to the map of default event parameters. These parameters persist across app runs. They are of lower precedence than event parameters, so if an event parameter and a parameter set using this API have the same name, the value of the event parameter will be used. The same limitations on event parameters apply to default event parameters.

Parameters

parameters
Parameters to be added to the map of parameters added to every event. They will be added to the map of default event parameters, replacing any existing parameter with the same name. **Valid parameter values are String, long, and double.** Setting a key's value to null will clear that parameter. Passing in a null bundle will clear all parameters.

Valid parameter values are String, long, and double.

[darshankawar]

Valid parameter values are String, long, and double.

That is correct. The plugin is wrapper around native Firebase SDK and leverages what is provided by Android Firebase SDK, so this may not be an actual issue as bool is not a valid type to use and plugin throws correct error as reported originally.

That is correct. The plugin is wrapper around native Firebase SDK and leverages what is provided by Android Firebase SDK, so this may not be an actual issue as bool is not a valid type to use and plugin throws correct error as reported originally.

Since the flutter side accepts any object(primitive types), should not the flutter side warn us? or should not the types be limited to those three? If I have not to look the detail of the actual method, I would not have figured that out.

Then, I need to ask another question about that. Why the iOS accept the bool type? One platform accepts and the other does not. It looks weird when we think of Flutter's perspective

[russellwheatley]

@kkoken We have a PR for this reason which will enforce stricter types (i.e. strings & numbers) to avoid this confusion: #9520. Although setDefaultEventParameters() hasn't been included in the PR, I will update the description to mark this as a TODO. Thanks.

In relation to iOS accepting booleans. are you sure that is true? See docs: https://firebase.google.com/docs/reference/ios/firebaseanalytics/api/reference/Classes/FIRAnalytics#+setdefaulteventparameters:

Quote:

The same limitations on event parameters apply to default event parameters.

Then read the event parameters documentation: https://firebase.google.com/docs/reference/ios/firebaseanalytics/api/reference/Classes/FIRAnalytics#+logeventwithname:parameters:

Quote:

Only String, Int, and Double parameter types are supported

We checked the firebase events on BigQuery, and we were seeing the bool parameters.

Could swift/objc parse bool as int?

[russellwheatley]

@kkoken What type is it appearing as on BigQuery? We actually pass the values straight to logEvent with next to no type checking on values here.

If you check Flutter docs, a boolean passed over the method channel to obj-c implementation is parsed as NSNumber numberWithBool:. See docs. So maybe it is sent as a number?

We were sending as bool for both clients. Ios was appearing on BigQuery and android was not. Thats why I only reported android.

I will talk again with the analytic team to send the previous output and get back to you with outputs.

[russellwheatley]

@kkoken sorry, my question wasn't worded correctly. I know you're sending the value as a boolean. I want to know if it appears as a boolean on BigQuery?

I'm wondering if the Firebase iOS SDK is reading the value as a number and sending it along as a number to Analytic's server. Or, maybe it doesn't type check for boolean as might be the case for android, and that is why you're able to get a boolean in BgQuery 🤔

[kkoken]

@russellwheatley I am very sorry for the late response. I talked with the analytic team, and they said they saw the data as bool on BigQuery. Also, I checked our app's FirebaseCrashlytics iOS logs.

the parameters' values are shown as int. I am adding the screenshots to look more in detail.
(PS: parameter names can differ, but they are identical.)

(isFree = isPremium, pushOptIn = optIn, isGranted = iysPermitted)

[kkoken]

@russellwheatley any news? I can offer my help on this matter.

[russellwheatley]

Hey @kkoken, we're waiting for confirmation from the Analytic's team. However, all signs indicate that the values accepted are string, int, and double parameter types. Once we have the green light, we will be strongly typing the inputs accepted for default event parameters and custom events which will be updated in this PR. I'd recommend following the documentation if you don't want unexpected results.

Thank you very much for your answer. I am looking forward to checking the changes in the documentation.

[russellwheatley]

We have updated the setDefaultEventParameters() implementation to assert() on the values accepted. See here: #9520

In a nutshell; default parameters can only have the value num, String or null.
