On my way implementing firebase analytics into my flutter app, i cant get the proper events to trigger or i dont get how this should work. Lets take the following code:
firebaseAnalytics.setCurrentScreen(screenName: "Dashboard");
When i trigger this event, in the Firebase Analytics debug view i see this:
The same when i trigger the screen changes automatically via:
navigatorObservers: [
FirebaseAnalyticsObserver(analytics: appState.firebaseAnalytics),
],
So my question is: Why does Analytics prints out "screen_view" instead of "Dashboard" or any other name i have in my named routes ??
The screen name is in fact submitted to the inner workings of the API cause i debugged firebase_analytics.dart on that place:
Future<void> setCurrentScreen(
{#required String screenName,
String screenClassOverride = 'Flutter'}) async {
if (screenName == null) {
throw ArgumentError.notNull('screenName');
}
await _channel.invokeMethod<void>('setCurrentScreen', <String, String>{
'screenName': screenName,
'screenClassOverride': screenClassOverride,
});
}
Answering my own question and thus wasting the bounty is hard but thats the way it is. Here are my findings:
The user provided screenName in the API gets submitted to the Firebase Analytics Dashboard but you need to drill down on the event "screen_view" to see the actual clicked screen Names you supplied. Unfortunately the user supplied Name wont be shown in the debugView of the Firebase Analytics console which got me on the wrong trail in the first place, thinking that its missing altogether, which is wrong.
tl;dr: screenName is just a parameter of screen_view Event and its right inside the screen_view event which you can drill down on.
Why route names don't show in the DebugView by using navigatorObservers? Looking for an explanation to this issue I got here and found the answer in Marc's Answer. It is actually being collected and is located as a parameter called firebase_screen.🧐

Edited Question :
I have an issue with Firebase Dynamic Links Packag , My goal is getting know if new user installed and opend my app for first time to give him a rewards like 10 point . I tried to search everywhere but no answer,in firebase website there is option to know if user install for first time.
My Goal is : Getting value for first time install & how to debug this code ?
initDynamicLinks when app Lanched :
void initDynamicLinks() async {
FirebaseDynamicLinks.instance.onLink(
onSuccess: (PendingDynamicLinkData dynamicLink) async {
final Uri deepLink = dynamicLink?.link;
if (deepLink != null) {
Navigator.pushNamed(context, deepLink.path);
}
},
onError: (OnLinkErrorException e) async {
print('onLinkError');
print(e.message);
}
);
final PendingDynamicLinkData data = await FirebaseDynamicLinks.instance.getInitialLink();
final Uri deepLink = data?.link;
if (deepLink != null) {
Navigator.pushNamed(context, deepLink.path);
}
}
.
You're mixing two things here.
The First-opens tab gives you the number of unique users who clicked on your Firebase Dynamic Link for the first time.
If you want to know how many unique users used your app, by clicking the Firebase Dynamic Link or not to get to your app, you have to implement the Firebase Analytics plugin to your app.
This way you'll get access to Dashboards showing you how many Unique users you have.
EDIT
Reading your comment, looks like your question is not related to your problem.
What you want here is to attribute rewards for users who invited their friends thanks to a referral link.
Since I never implemented this witout a dedicated backend, the only thing I can share is a use-case I used some time ago explaining the logic to follow to implement it.
https://firebase.google.com/docs/dynamic-links/use-cases/rewarded-referral
EDIT 2
The logic explained in the documentation is the following :
1- Generate a Dynamic Link for UserA.
2- UserA sends the Dynamic Link to someone (called UserB).
3- When UserB starts the app from a Dynamic Link, retrieve the referral informations in the app (to retrieve UserA's informations)
4- Call a route on your backend to attribute the reward to UserA (and check if UserB is really a new user in your database).
The point is, you shouldn't manage a referral/referrer relationship on the client's side (it would be way too easily abused/hacked).
It's the job of a backend (or cloud function) to manage this.
Once you have received the link clickthrough in your app use the google_analytics package to log an event.

Flutter log event with google analytics
To be honest i have never used Firebase Dynamic Links , But if your Goal is to Achieve a first open or login token , you can always use the Sharedpreferences package , in my case iam using it to navigate to different pages passed on the first login value .
i think that Sharedpreferences is more reliable and easier than what you are trying to achieve with firebase
UPDATE:
what you actually want to do is make a firebase collection with IMEI numbers , when there is a new IMEI that means a new user , when that IMEI is in your collection that means that the app is not installed for the first time ,
you can use this package imei_plugin to get IMEI number and store it on firebase
I'm running in trouble here with Firebase.
The code is in flutter, I am testing in iOS
It's all going well, but when I try to get the dynamic link sent from:
auth.sendSignInWithEmailLink(parameters);
I get a debug message:
[Firebase/Analytics][I-ACS023001] Deep Link does not contain valid required params. URL params: {
amv = 16;
apn = "com.myproject.app";
ibi = "com.myproject.app";
ifl = "https://myproject-com.firebaseapp.com/__/auth/action?apiKey=XXXXXXXXXXX&mode=signIn&oobCode=XXXXXX&continueUrl=https://myproject-com.firebaseapp.com/email123&lang=en";
link = "https://myproject-com.firebaseapp.com/__/auth/action?apiKey=XXXXXXX&mode=signIn&oobCode=XXXXXX&continueUrl=https://myproject-com.firebaseapp.com/email123&lang=en";
}
where I changed my project name to "myproject" and put XXX inplace of apiKey/oobcode
and then, when I try to get the dynamic link with my app
final PendingDynamicLinkData data = await FirebaseDynamicLinks.instance.getInitialLink();
data is null.
So I am guessing Firebase Analytics is processing it and "killing" the dynamic link before my app can parse it.
Anyone managed to go through this?
I found the problem.
It is not that Firebase Analytics was "consuming" and killing the deep link.
The thing is that in iOS still today there is a delay the link and the state cycle...

This link explains it, problem 2 in the blog post.
Solved. I can still use analytics in Firebase.
It is impossible to remove analytics btw, you can only disable it.
So, I am currently using Flutter to develop an IOS-App and added Firebase.
I am trying to use PayPal-Connect with the url_launcher package. As the PayPal-Connect link looks like this:
https://www.sandbox.paypal.com/connect?flowEntry=static&client_id=[<my_client_Id>]&scope=&redirect_uri=[<my_url>]
I am trying to use Firebase Dynamic Links for the redirect_uri to go back to the app and fetch the data I got from Pay-Pal as url parameters. The problem is that whenever I run this code:
Future<void> retrieveDynamicLink() async {
final PendingDynamicLinkData data = await FirebaseDynamicLinks.instance.getInitialLink();
final Uri deepLink = data?.link;
if (deepLink != null) {
print(deepLink);
print(deepLink.queryParameters['code']);
}
}
The logs say:
flutter: https://domain.page.link/ppc
flutter: null
But I know from the Paypal-Connect Docs that they add a code=[<some_code>] parameter.
But is the thing I plan to do even possible with Dynamic Links? Or Am I doing something completely wrong?
Checking the implementation, it looks like you're trying to implement something similar to a reward referral use case. The reason why deepLink.queryParameters['code'] returns null is because there's no code parameter configured on the deep link of the Firebase Dynamic Link that has been handled.
To configure a query parameter for code, the deep link of your Dynamic Link should look something similar to https://example.com/?code={CODE}
I'm generating an event in my mobile app using this method:
var Param = {};
Param.VALUE = response[1];
firebase.analytics().logEvent(`Purchase_report`, Param);
and I am able to receive the log in StreamView and also Event dashboard. I also can see my parameter("VALUE") by correct sent value from my application in these views. However I don't know how may I link this value to the event value and I always see "0" as event value. Please refer to these images for more clarifications:
I found my answer. The point is if you set a value parameter, it takes about ONE DAY for an update to be appear in the firebase console.So I finally saw my report after one day.
I am new to firebase and I am having a bit of a nightmare trying to adapt old code to what is now deprecated and what is not. I am trying to write a function which updates one "single" record in my datasource using the now approved $save()promise but it is doing some really strange stuff to my data source.
My function (should) enables you to modify a single record then update the posts json array. However, instead of doing this, it deletes the whole datasource on the firebase server and it is lucky that I am only working with testdata at this point because everything would be gone.
$scope.update = function() {
var fb = new Firebase("https://mysource.firebaseio.com/Articles/" + $scope.postToUpdate.$id);
var article = $firebaseObject(ref);
article.$save({
Title: $scope.postToUpdate.Title,
Body: $scope.postToUpdate.Body
}).then(function(ref) {
$('#editModal').modal('hide');
console.log($scope.postToUpdate);
}, function(error) {
console.log("Error:", error);
});
}
Funnily enough I then get a warning in the console "after" I click the button:
Storing data using array indices in Firebase can result in unexpected behavior. See https://www.firebase.com/docs/web/guide/understanding-data.html#section-arrays-in-firebase for more information. Also note that you probably wanted $firebaseArray and not $firebaseObject.
(No shit?) I am assuming here that $save() is not the right call, so what is the equivalent of $routeParams/$firebase $update()to do a simple binding of the modified data and my source? I have been spending hours on this and really don't know what is the right solution.
Unless there's additional code that you've left out, your article $firebaseObject should most likely use the fb variable you created just before it.
var article = $firebaseObject(fb);
Additionally, the way in which you're using $save() is incorrect. You need to modify the properties on the $firebaseObject directly and then call $save() with no arguments. See the docs for more.
article.Title = $scope.postToUpdate.Title;
article.Body = $scope.postToUpdate.Body;
article.$save().then(...
