How to send notification to user on data changes in database using firebase ?
I am newbie and searched everywhere no such help.. please help me.
I got to know that it's possible using firebase cloud function but I did not got any example code to understand it. So please help by giving any example code.
Have a look at the first use-case mentioned in the Firebase documentation and the sample code for that use-case. They quite literally describe what you're asking for.
Note that this code is non-trivial, since the entire use-case is quite involved. You will have to make sure you understand all parts well, before you try to make any changes to the sample code. To get this understanding, you might be better served by following the more basic documentation for the Realtime Database and Cloud Messaging, and the codelab for iOS, Android, and/or Web.

Hello I am trying to firebase in my app and I keep running into problems. I've tried the suggestions in this screen shot, but I think perhaps I am not understanding properly.
Its saying cannot find correct Provider, I am guessing it can't find it in the tree. But it looks to me as if it is there
Here is my main where I call provider
So it turns out this is what works. Now i just need to figure out how to present the data.
I'm facing an issue where when I sign out a user (using FirebaseAuth.signOut() method) and sign in with another user, information of the previous user are loaded instead of the new one.
I believe this is caused by this information still being accessible in firebase's cache.
Is there a way to force firebase to clear its local cache?
Cheers!
For Android, there is FirebaseFirestore.clearPersistence().
For JavaScript/web, there is Firebase.clearPersistence().
For iOS, there is Firebase.clearPersistence().
Flutter does not seem to have this API yet.
Bear in mind that the clearPersistence API is not meant for the specific case you're talking about. If you read the API docs carefully, you can see they're meant for testing.
You might want to do a little more debugging to figure out what exactly it is that's not working the way you expect. Since you're not showing any code, it's hard to tell if you might be doing something wrong.
You can use the async call FirebaseFirestore.instance.clearPersistence(); for flutter projects.
Check this answer.
If clearPersistence() doesn't work, Programmatically restart your app
you can restart your app like this: https://stackoverflow.com/a/50116077/10041654
in addition, while restarting init your firebase: https://github.com/The-ring-io/flutter_phoenix/issues/27#issue-1490150037
I am using firebase functions and I am trying to find out if my users are subscribed to my app by using a firebase function. I wonder how the authentication should be done since I am trying to interface between two google services.
You asked this question a long time ago but since you haven't received an answer yet and for anyone else stumbling across this question:
I found this blog post giving a detailed description of how to do so.
It is basically straight forward, but the blog post guides you through it very well, I'm currently following it myself.
Disclaimer: I haven't published my app yet so I cannot verify if it works. If it doesn't, I will add an edit to this answer.
My question is pretty simple, I don´t know how to simulate multiple updates inside Firebase Simulator. Since I don´t know how to even start I can´t provide any code. Any guidance will be very helpful.
There is currently no way to execute multi-location updates in the Firebase Database security rules simulator.
It would be great to have that functionality, so can you file a feature request for it here?
I have done java for 6 months but when i try to go through the firebase android documentation on my own I don't understand it .I cant use the documentation on my own. please tell me what I should do to properly understand it thanks.
The documentation is one of the most clear ones i ever seen, it is detailed and organized, but you can also check the codeLab
